[0033] The working principle of the present invention is: When the present invention is used, the stapler installation tube that needs to be punched is placed in the inner wall of the rubber installation tube 8, and then the rotating arm 14 is rotated. The rotating arm 14 drives the blocking block 15 to block the rubber installation tube 8, and then the punching needle 3 is moved to the inside of the perforation 10 to prepare for punching, and then the driving motor 21 is started to drive the driving motor 21 to drive the rotating disc 22 to rotate. Since the matching column 20 is not installed in the center of the rotating disc 22, when the rotating disc 22 drives the matching column 20 to move in the inner wall of the rectangular opening 19, the matching column 20 will drive the matching plate 18 to move through the rectangular opening 19, and the matching plate 18 will drive the movable plate 6 to move back and forth along the outer wall of the sliding column 17 in a fixed direction. It only needs to increase the rotation speed of the driving motor 21 to achieve the effect of vibration on the movable plate 6, which helps to make the iron sand in the squeezing bag 5 more solid, thereby increasing the positioning effect of the stapler installation tube; Since the movable plate 6 will move on the outer wall of the sliding column 17 when it vibrates, when the movable plate 6 moves on the outer wall of the sliding column 17, it will drive the two sets of mounting strips 23 to move, and the mounting strip 23 drives the rack 25 to abut against the card-connecting gear 26. When the rack 25 is carded with the card-connecting gear 26 and abuts against the outer wall of the card-connecting gear 26 to move back and forth, when the mounting strip 23 drives the rack 25 to abut against the outer wall of the card-connecting gear 26 to reset, since the tooth directions of the rack 25 and the outer wall of the card-connecting gear 26 are opposite, the rack 25 will enter the mounting strip 23 when it resets. When the rack 25 drives the card-connecting gear 26 to rotate, the card-connecting gear 26 drives the card-connecting box 35 to rotate, and the card-connecting box 35 drives the third spring 38 to rotate through the card-connecting circular groove 36, and the third spring 38 drives the mounting round block 40 to rotate. The mounting round block 40 drives the recovery wheel 34 to rotate, the recovery wheel 34 drives the connecting column 29 to rotate, the connecting column 29 drives all the rotating arms 27 to rotate, the rotating arms 27 drive the clamping strip 43 to abut and move with the inner wall of the fixed tube 33, and when the clamping strip 43 is clamped with the clamping tooth 32, the clamping strip 43 will limit the connecting column 29 through the rotating arm 27, and the connecting column 29 will limit the recovery wheel 34, and it cannot rotate in the opposite direction. It is worth noting that when the recovery wheel 34 cannot pull the tension rope 12, the clamping gear 26 drives the clamping circular groove 36 to rotate through the clamping box 35. Since the recovery wheel 34 cannot rotate, the abutting ball 39 will break away from the abutment with the clamping circular groove 36 and enter the inner wall of the clamping circular groove 36 of the next group to clamp; As the recovery wheel 34 pulls the tension rope 12, the two groups of tension ropes 12 tighten all the extrusion ropes 11, and as the extrusion ropes 11 are tightened, the extrusion ropes 11 move along the rubber hose on the outer wall of the extrusion bag 5 and the inner wall of the movable tube 16, and the rubber hose and the movable tube 16 can well reduce the friction between the extrusion rope 11 and the extrusion bag 5. As all the extrusion ropes 11 are gathered toward the direction of the rubber mounting tube 8, the extrusion ropes 11 can tighten and squeeze the extrusion bag 5. As the extrusion bag 5 is filled with iron sand, the extrusion bag 5 can squeeze the rubber mounting tube 8. The stapler mounting tube inside the tube 8 is squeezed and fixed, and the iron sand inside the extrusion bag 5 can make the extrusion bag 5 exert more uniform extrusion force on the outer wall of the rubber mounting tube 8, and the rubber mounting tube 8 exerts more uniform extrusion force on the stapler mounting tube. When the rubber mounting tube 8 is located at the bottom of the punching needle 3, the punching cylinder 1 is started to drive the moving plate 2 to move, and the moving plate 2 drives the punching needle 3 to punch the stapler mounting tube through the perforation 10. When the punching needle 3 punches the stapler mounting tube, the stapler mounting tube is subjected to more uniform force and is not easily deformed. Note that when it is necessary to limit the contact of the tension rope 12, it is only necessary to pull the movable sleeve 28 to move along the outer wall of the connecting column 29. When the movable sleeve 28 moves to the outer wall of the threaded rod 30, the movable sleeve 28 is threadedly connected to the outer wall of the threaded rod 30 through the threaded hole. During the movement, the movable sleeve 28 will drive the rotating arm 27 to fold and shrink, and the rotating arm 27 will drive the clamping strip 43 to disengage from the clamping of the clamping tooth 32. At this time, the movable sleeve 28 is disengaged from the connection with the outer wall of the threaded rod 30. At this time, the extrusion bag 5 drives the extrusion rope 11 to reset due to its own elastic force, and the extrusion rope 11 drives the corresponding tension rope 12 to reset, and the tension rope 12 will drive the recovery wheel 34 to rotate and reset. The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
