Technical background: optical lens processing production need to constantly through the cutter rotating grinding, make final accord with a standard, the existing optical lens processing cutting tool are unibody design, usually when a blade failure or other cannot continue to use, can only change the knife dish whole, design has certain defects, the cost is higher. In addition, the cutter in machining process are prone to wear and tear, the phenomenon such as loose, directly affect the machining accuracy. Cut out of the optical lens surface finish is poor, poor quality of the finished product. In addition, the tool is usually single processing, when the blade of the cutter wear, can be to replace the new cutter, laborious, the cost is higher also. Technical implementation elements: the utility model aims to overcome the defects that exist in the existing technology, put forward a kind of optical lens processing cutting tool, structure design, not easy to damage, and the cutter is the blade, long service life and low cost. Of the technical scheme of the utility model is that: an optical lens processing cutting tool, including the seat and disc knife seat can remove some cutter alone; Described the knife seat along the circumferential direction is equipped with several installation groove, the installation groove with fixed seat; Cutter including the handle and cutter head, cutter handle through bolted it fixed seat; It is a knife on a counterweight. Further, described in the cutter central triangle hole is opened. Further, described in central cutter opening with stiffener. Further, described the fixed seat is equipped with mounting holes, the cutter handle instrumentation described in the installation hole. Described further, set in the handle for bolt connecting hole, the wear of the connection holes for long holes along the handle length direction. Further, the installation groove as trapezoidal groove. Further, double blade cutter has described acute Angle intersect. Using the above technical scheme, the utility model beneficial effects as follows: 1) When the cutter wear and tear or damage, simply unscrewed the bolts, within the permanent seat on the new cutter can, at work, because of the balance block, even at high speed cutter holder is also very smooth. Cutter to receive strength evenly within the fixed seat, and work closely fixed bridge with a knife, knife is not easy to break, greatly extend the service life. 2) Open a triangle middle hole cutter, to reduce the weight of the cutter, reduces the total weight of this cutter, due to the central hole, so the cutter itself has certain elasticity, and encountered a sudden load change is not easy to break, as a result of the cutter central hole with stiffener, therefore, the central hole of cutter structural strength has also been a reliable guarantee. 3) Double blade cutter with acute Angle intersection, regardless of the cutter in the knife holder is forward or backward state, can very good cutting effect. Illustrated instructions in order to more clearly this utility model example existing technology or the technical proposal, the following described for example or existing technology in the appended drawings of the need to use introduce simply, clearly, described below the appended drawings is just some of the utility model example, for the field common technical personnel, under the premise of not pay a creative labor, can also according to the appended drawings for other appended drawings. Figure 1 for the utility model structure schematic diagram; Figure 2 for the utility model of cutter structure diagram. Among them: 1 - The knife; 2 - Cutter; 3 - Installation groove; 4 - The fixed seat; 5 - The handle; 6 - Cutting head; 7 - Bolt; 8 - Balance weight; 9 - Triangle hole; 10 - Strengthening rod; 11 - Connection hole; 12 - The blade; 13 - Weight loss. Concrete implementation way of the following will be combined with the appended drawings of the utility model implementation, this utility model implementation case clearly and completely describe the technical scheme of obviously, described the implementation of the case is just a part of the utility model implementation example, rather than the implementation of all cases. Based on the example of the utility model, the field common technical personnel under the precondition of not made a creative labor for all other cases, all fall within the scope of protection of the utility model. An optical lens processing cutting tool, as shown in figure 1 and figure 2, including 1 and disc knife block 1 can remove some cutter 2; Along the circumferential direction on knife block 1 has described several installation slot 3, the installation groove 3 with fixed seat 4; Cutter 2 including the handle 5 and 6 of the cutting tools, cutter 2 handle 5 through 7 fixed bolt it is fixed on a 4; It is a knife on a 1 a counterweight to 8. When cutter 2 worn or damaged, simply unscrewed the bolts (7, within the fixed seat four new cutter 2 can, at work, because of the balance block 8, even at high speed cutter holder is also very smooth. Cutter 2 within the fixed seat four force uniform, work closely and fixed bridge with a knife, the cutting tool is not easy to break, greatly extend the service life. Among them, the described runs triangle middle hole cutter 2 9. To reduce the weight of the cutter 2, reduces the total weight of this cutter, due to the central hole, so the cutter 2 itself has certain elasticity, and meet the sudden load change is not easy to break. The cutter 2 central hole with stiffener 10, to enhance the structural strength of the perforated cutter of 2. To be sure, in order to further reduce the weight of this tool, you can on the knife block 1 open 3 - symmetrical 5 hole 13 each weight loss, in reducing weight at the same time, tool does not affect the structural strength of cutter holder 1, because it is symmetrical design, also does not affect the knife block 1 rotational stability of the process, together with the balance of counterweight 8, in the process of turning, cutting tool overall stability is very good. , including 4 described the fixed seat is equipped with mounting holes, cutter 2 described the handle of the installation of instrumentation in the hole. Cooperate with stable, will not shift, ensure the stability of the cutter 2 work. Set in among them, described the handle 5 for bolt connecting hole 11, and wear of the connecting hole 11 for long holes along the handle length direction, can be adjusted according to the need to stretch out the length of the cutter 2. Among them, described in the installation groove 3 as the trapezoidal channel, make the fixed seat and cooperation more stable, in the production and processing, don't move, reduce the chances of the tool damage. Cutter 2 has described acute Angle intersection of 12 double edge, regardless of the cutter 2 at the 1 knife is forward or backward state, can very good cutting effect. To be sure, cutter 2 for symmetric structure design, install and use, on both sides of the blade can be used, because both sides have the blade, when one side blade wear, as long as you turn around the installation direction of cutter 2, or the rotation direction of cutter holder, can continue to use this tool for processing, again as a result, the cutting tool service life is long, the cost is low. The utility model structure design is reasonable, when cutter 2 worn or damaged, simply unscrewed the bolts (7, within the fixed seat four new cutter 2 can, at work, because of the balance block 8, even at high speed cutter holder is also very smooth. Cutter 2 within the fixed seat four force uniform, work closely and fixed bridge with a knife, the cutting tool is not easy to break, greatly extend the service life. Described above only for the better implementation of the utility model case, is not used to limit the utility model, all within the spirits and principles of the utility model, for any modification, equivalent replacement, improvement, etc. , shall be included within the scope of protection of the utility model.
