One end of the bidirectional screw rod 13 is butt-jointed, and a bearing seat 16 is provided at the end of the bidirectional screw rod 13 away from the motor 12. Two different threaded portions on the outer surface of the bidirectional screw rod 13 are provided with moving blocks 14. The other end of the bidirectional screw rod 13 is fixedly connected to the inner surface of the bearing seat 16. The outer surface of the bearing seat 16 is fixedly connected to the inner wall of the operating table 11 away from the motor 12. The two different threaded portions on the outer surface of the bidirectional screw rod 13 are threadedly connected with the moving blocks 14. Slide rods 15 are provided on both sides of the bidirectional screw rod 13. The tops of the two moving blocks 14 are provided with There is a clamping block 17, the inner wall of the card slot opened by the moving block 14 is slidably connected with a slide bar 15, the two ends of the two slide bars 15 are respectively fixedly connected to the two sides of the inner wall of the operating table 11, the bottom of the clamping block 17 is fixedly connected to the top of the moving block 14, and the two clamping blocks 17 are arranged on the opposite side with a plurality of buffer grooves 18 in an array, and a plurality of movable rods 19 are arranged in the plurality of buffer grooves 18, and the outer surfaces of the plurality of movable rods 19 are provided with buffer springs 110, and the end of the movable rod 19 away from the clamping block 17 is provided with a buffer pad 111, and the outer surface of the movable rod 19 is connected to the buffer spring 110. The inner wall of the groove 18 is slidably connected, and the other end of the movable rod 19 passes through the inner circle of the buffer spring 110 and is fixedly connected to the side of the buffer pad 111 close to the clamping block 17. A curtain 112 is provided in the card slot opened on the top of the operating table 11. One end of the buffer spring 110 is fixedly connected to the side of the clamping block 17 close to the buffer pad 111, and the other end of the buffer spring 110 is fixedly connected to the side of the buffer pad 111 close to the movable rod 19. The two ends of the curtain 112 are respectively fixedly connected to the opposite sides of the two moving blocks 14, and an anti-wear mechanism 2 is provided on the operating table 11.
[0024] In this embodiment, when the staff uses the clamp to clamp the fingerprint prism, the fingerprint prism is first placed on the placement plate 21, and the bidirectional screw 13 is driven to rotate by starting the motor 12, so that the two moving blocks 14 and the clamping block 17 will move relative to or towards each other synchronously. At the same time, during the movement of the moving block 14, the card slot opened on one side will slide in contact with the surface of the slide bar 15 to ensure that the moving block 14 can remain horizontal when moving, and at the same time provide a support effect for the moving block 14. When the two clamping blocks 17 clamp the two sides of the fingerprint prism respectively, the buffer pad 111 will contact the fingerprint prism, which will then push the movable rod 15. 9 generates a thrust, so the movable rod 19 will be recessed into the buffer groove 18. At the same time, as the buffer pad 111 moves toward the clamping block 17, the buffer spring 110 will also be squeezed and deformed, thereby ensuring that the edge of the fingerprint prism will not be damaged due to excessive clamping force. At the same time, the fingerprint prism that is firmly clamped will not shift during processing, which can ensure the stability of the fingerprint prism during processing and avoid processing errors caused by unstable clamping, thereby improving processing accuracy. In addition, the curtain 112 will block the debris generated during these processing to prevent these debris from entering the interior of the operating table 11 and affecting the internal components.

[0026] In this embodiment, the bottoms of the four legs 22 are fixedly connected to the top of the operating table 11, so as to ensure that the placement plate 21 will not move or slide during operation, thereby ensuring stability and safety during processing. In addition, an anti-wear pad 23 is fixedly connected to the placement plate 21, which can effectively provide friction for the fingerprint prism and avoid wear on the surface of the fingerprint prism due to friction.
[0027] The utility model provides a fingerprint prism processing fixture, and the specific working principle is as follows:
[0028] When the staff uses the clamp to clamp the fingerprint prism, first place the fingerprint prism on the placement plate 21, then start the motor 12 to drive the bidirectional screw 13 to rotate, and then the two moving blocks 14 and the clamping block 17 will move synchronously relative to or towards each other. In this process, the card slot opened on one side of the moving block 14 will slide in contact with the surface of the slide bar 15 to ensure that the moving block 14 can remain horizontal when moving. When the two clamping blocks 17 clamp the two sides of the fingerprint prism respectively, the buffer pad 111 will contact the fingerprint prism. This contact will generate a thrust acting on the movable rod 19. Therefore, the movable rod 19 will be recessed into the buffer groove 18. At the same time, as the buffer pad 111 moves toward the clamping block 17, the buffer spring 110 will also be squeezed and deformed. Through the cooperation of the buffer pad 111 and the movable rod 19, the clamp can provide appropriate force during the clamping process, which can not only ensure the stability of the fingerprint prism, but also avoid damage to it.
