A rotating column 15 is rotatably connected to the bottom of the operating table 1. A rotating rod 17 is fixedly connected to the rotating column 15. A moving rod 18 is rotatably connected to the opposite ends of the rotating rod 17. One end of each moving rod 18 is rotatably connected to the bottom of the corresponding sliding block 6. A worm gear 16 is fixedly connected to the bottom of the rotating column 15. The worm gear 16 meshes with the worm gear 13. The buffer assembly 10 includes an outer frame 1001 fixedly connected to one side of the snap-fit ​​block 9.

With the buffer of multiple buffer springs 1003, it is beneficial to reduce the probability of the material being damaged by clamping.

[0033] To achieve rapid assembly and disassembly, the quick-disassembly structure 8 includes an elliptical disk 806 rotatably connected to one side of the fixed block 7. A toggle lever 807 is fixedly connected to one side of the elliptical disk 806. Two sliding rods 801 are fixedly connected to the opposite side of the fixed block 7. One end of each sliding rod 801 is fixedly connected to a limiting plate 802. A moving plate 803 is slidably connected to the two sliding rods 801 on the same side. A first spring 805 is movably mounted on each sliding rod 801.

One end of each locking pin 804 is slidably connected to the corresponding side of the fixed block 7. Each locking pin 804 is adapted to a corresponding locking hole. When the actuating rod 807 is moved, the actuating rod 807 drives the elliptical disk 806 to rotate. The elliptical disk 806 presses the two movable plates 803, causing the two movable plates 803 to slide on the corresponding sliding rod 801 and press the first spring 805. The two movable plates 803 drive the corresponding locking pins 804 to move, causing the locking pins 804 to disengage from the corresponding locking holes. This makes it convenient for workers to replace different clamping blocks 1002 according to different shaped materials without removing bolts, which helps to improve replacement efficiency.

[0034] Working principle: Actuating lever 807 rotates the elliptical disk 806, causing it to press against two movable plates 803. These plates slide on corresponding sliding rods 801 and compress the first spring 805. The two movable plates 803 then move their corresponding locking pins 804, disengaging them from their corresponding locking holes. This allows workers to easily replace different clamping blocks 1002 according to different material shapes without disassembling bolts, improving replacement efficiency. The servo motor 14... The rotating rod 12 drives the worm gear 13 to rotate, and the worm gear 13 drives the rotating column 15 to rotate through the worm wheel 16. The rotating column 15 drives the moving rod 18 to move through the rotating rod 17. The moving rod 18 drives the fixed block 7 to move through the sliding block 6. The fixed block 7 drives the outer frame 1001 to move through the snap-fit ​​block 9. The outer frame 1001 drives the clamping block 1002 to move, so that the rubber pads on the opposite side of the two clamping blocks 1002 clamp the material on both sides. With the buffering effect of multiple buffer springs 1003, it helps to reduce the probability of the material being damaged by clamping.
