[0030] Embodiment 2: On the basis of embodiment 1, a slide groove 5 is provided at the bottom of the moving block 1, a cross bar 8 is fixed in the slide groove 5, the cross bar 8 is inserted into the inside of the blade 4, one end of the blade 4 is located in the slide groove 5, and the end of the blade 4 can move in the slide groove 5, a limit plate 6 is fixed at the bottom of the moving block 1, the limit plate 6 is inserted into the inside of the blade 4, the blade 4 can move outside the limit plate 6, and multiple groups of blades 4 are provided.

[0031] Two sets of first L-shaped plates 14 are fixed on the surface of the connecting rod 9. The other end of the first L-shaped plate 14 is inserted into the inside of the moving block 1. The end of the first L-shaped plate 14 can telescopically move inside the moving block 1. A second L-shaped plate 18 is fixed on the surface of the connecting rod 9. The other end of the second L-shaped plate 18 is inserted into the inside of the moving block 1, and one end of the second L-shaped plate 18 inserted into the moving block 1 can telescopically move inside the moving block 1. Multiple moving grooves 13 are formed on the surface of the connecting rod 9. An adjusting rod 21 is inserted into the moving groove 13. The adjusting rod 21 can move in the moving groove 13. A first holding plate 22 and a second holding plate 23 are fixed at the end of the adjusting rod 21. The heights of the first holding plate 22 and the second holding plate 23 are different, and both the first holding plate 22 and the second holding plate 23 move along with the connecting rod 9. Both the first holding plate 22 and the second holding plate 23 are trapezoidal. Both the first holding plate 22 and the second holding plate 23 are located between the blades 4. When the first holding plate 22 and the second holding plate 23 move, the surfaces of the first holding plate 22 and the second holding plate 23 abut against the ends of the blades 4. C-shaped plates 15 are fixed on both sides of the sleeve ring 17. A cross plate 10 is fixed at the bottom of the C-shaped plate 15. The cross plate 10 moves along with the C-shaped plate 15. A card slot 11 is formed on the surface of the cross plate 10. An extension plate 12 is fixed at the end of each blade 4. Teeth are provided on the surface of the extension plate 12.

The screw rod 16 can move inside the second L-shaped plate 18, and the end of the screw rod 16 abuts against the surface of the second L-shaped plate 18. The other end of the screw rod 16 is screwed into the inside of the moving block 1. By screwing the screw rod 16, the end of the screw rod 16 abuts against the second L-shaped plate 18 to move. A sleeve ring 17 is sleeved on the surface of the screw rod 16. A limiting strip 20 is provided on the surface of the screw rod 16. Multiple groups of limiting strips 20 are evenly distributed on the surface of the screw rod 16. A rubber strip that is mutually clamped with the limiting strip 20 is arranged inside the sleeve ring 17.

[0033] The lifting rod 2 is used to drive the moving block 1 to descend. The limiting rod 3 plays a limiting role. The blade 4 at the bottom of the moving block 1 descends along with the moving block 1 for operation. When it is necessary to adjust the distance between the blades 4, the screw rod 16 is rotated. The end of the screw rod 16 abuts against the surface of the second L-shaped plate 18, so that the second L-shaped plate 18 and the first L-shaped plate 14 are inserted into the inside of the moving block 1. The connecting rod 9 moves along with the first L-shaped plate 14 and the second L-shaped plate 18. The connecting rod 9 approaches the moving block 1, so that the adjusting rod 21 and the first abutting plate 22 approach the moving block 1 along with the connecting rod 9. The first abutting plate 22 abuts between the blades 4. Both the first abutting plate 22 and the second abutting plate 23 abut against the ends of the blades 4. The first abutting plate 22 and the second abutting plate 23 are at different heights to prevent the first abutting plate 22 and the second abutting plate 23 from interfering with each other. Through the abutment of the first abutting plate 22, the blades 4 move in the sliding groove 5 to adjust the distance between the blades 4. Since the advancing distances of the first abutting plate 22 and the second abutting plate 23 are the same, the distances between the two groups of blades 4 are the same, and multiple groups of blades 4 can adjust the distance simultaneously. The piston rod 19 drives the C-shaped plate 15 to move. The C-shaped plate 15 drives the cross plate 10 at the bottom to move, so that the clamping groove 11 is stuck on the surface of the extension plate 12. The surface of the clamping groove 11 is provided with teeth, and the surface of the extension plate 12 is provided with teeth. After the clamping groove 11 is stuck on the surface of the extension plate 12, the position of the blade 4 is limited to stabilize the position of the blade 4. Moreover, the sleeve ring 17 moves along with the C-shaped plate 15, and the sleeve ring 17 is stuck on the surface of the limiting strip 20, playing a role in preventing the screw rod 16 from rotating.
