[0028] When ready for use, the operator places the workbench 1 in the designated position and adjusts the multiple U-shaped plates 21 through the two sets of adjustment mechanisms 27, and then places the absorbing material inside the four U-shaped plates 21. After the placement is completed, the operator twists the threaded rod 22 on one side, and the threaded rod 22 rotates and moves downward, thereby driving the pressure plate 23 to squeeze and fix the absorbing material. When the threaded rod 22 moves, the limit block on the gear 25 slides in the slide groove 24, thereby driving the gear 25 to rotate at the same time, and the gear 25 drives the synchronous belt 26 to move, and the synchronous belt 26 drives the gear 25 on the other side to rotate, thereby driving the threaded rod 22 on the other side to rotate, so that The device only needs to rotate one side of the threaded rod 22 to drive the two pressure plates 23 at the same time, and the operation is simple, which improves the practicality of the device; the operator turns on the servo motor 272 to drive the bidirectional threaded rod 271 to rotate, so that the bidirectional threaded rod 271 drives the two connecting blocks 273 to move relative to each other, thereby driving the positions of the two U-shaped plates 21 to be adjusted, which is simple to operate and improves the convenience of the device; a protective shell 4 is fixedly connected to the top of the two U-shaped plates 21, and the protective shell 4 can cover the gear 25 and the synchronous belt 26 to prevent dust and the like from falling onto the surface of the gear 25 and the synchronous belt 26, which may cause the gear 25 and the synchronous belt 26 to get stuck after long-term use, thereby improving the stability of the device.
