An adjustment structure is provided between the two mounting seats 2, and a cutting structure is provided on the top of the operating table box body 1.

[0024] Specifically, when turning the handle 1, the worm 15 rotates inside the circular convex groove 200, the worm 15 engages with the worm wheel 14, and the worm wheel 4 drives the threaded rod 3 to rotate. The threaded rod 3 is threadedly connected to the internal threaded tube 6, and the internal threaded tube 6 drives the two sliders 202 to slide in the two slide grooves 201. The internal threaded tube 6 moves out of the circular convex groove 200, thereby adjusting the position of the clamping block 7 to achieve clamping and fixation of the steel part. This structure sets the worm wheel 4 and the worm 15 to have a self-locking effect, thereby solving the problem that the screw may loosen during the cutting process, resulting in unstable fixation of the steel part, and ensuring the cutting accuracy and quality.
