[0025] The moving block 3 and the clamping block 4 lack a guiding structure on the processing table 1, which will affect the stability of the moving block 3 and the clamping block 4 when moving. Two mounting frames are symmetrically arranged on the upper end of the processing table 1. The moving block 3 and the clamping block 4 can slide in the mounting frames. The inner walls of the mounting frames are provided with limiting grooves. Limiting blocks cooperating with the limiting grooves are provided on both sides of the moving block 3 and the clamping block 4. The slide groove 6 and the limiting groove are both rectangular. Through the cooperation of the mounting frames and the limiting blocks with the limiting grooves, a guiding structure can be provided for the moving block 3 and the clamping block 4 on the processing table 1, which can improve the stability of the moving block 3 and the clamping block 4 when moving.
