[0024] Referring to Figure 2 、 Figure 3 , a connection top block 7 is fixedly welded to the top of the connecting rod 2. An insertion block 4 protrudes below the connecting rod 2. Two groups of insertion blocks 4 are symmetrically and spaced apart at the bottom of the connecting rod 2. Insertion holes 3 are formed in the insertion blocks 4; the upper surface of the connection top block 7 has a connection groove 6. The insertion block 4 is adapted to the connection groove 6 and vertically slides along the inner side wall of the connection groove 6. Limit insertion blocks 9 are fixedly installed on the outer walls on both sides of the connection top block 7. The limit insertion blocks 9 are L-shaped structures and penetrate into the connection top block 7 to be inserted and fixed with the insertion block 4. Clamping blocks 5 are fixed on the outer wall of the connecting rod 2. The clamping blocks 5 are spaced apart and clamp the side wall of the workpiece placement frame 1.

[0025] Referring to Figure 4 , a limit insertion hole 14 is provided on the side wall of the connection top block 7, and the limit insertion block 9 penetrates into the limit insertion hole 14. One end of the connection top block 7 away from the limit insertion hole 14 is fixedly connected to a connecting pipe 11. The connecting pipe 11 is inserted into the connection top block 7 and horizontally slides inside the connection top block 7. The connecting pipe 11 has a hollow threaded inner hole structure, and a driving screw 12 is threadedly installed inside the connecting pipe 11. One end of the driving screw 12 away from the connecting pipe 11 is fixedly connected to a rotating rod 10.

[0026] The rotating rod 10 is horizontally and rotatably installed inside the connecting top block 7, and a fixed block 13 is rotatably sleeved outside the rotating rod 10. The fixed block 13 is fixed on the inner wall of the connecting top block 7.

After the insertion block 4 fits into the connecting groove 6 and slides in, rotate the regulating shaft 8. The regulating shaft 8 drives the rotating rod 10 to rotate through the cooperation of the driving gear and the driven gear. Then the driving screw rod 12 fixedly connected to the rotating rod 10 rotates under force, and thus the connecting pipe 11 threadedly sleeved outside the driving screw rod 12 is forced to retract towards the inside of the connecting top block 7. The other end of the connecting pipe 11 drives the limiting insertion block 9 to slide into the connecting groove 6 through the limiting insertion hole 14 and is inserted into the insertion block 4 installed inside the connecting groove 6.
