[0106] The pull parts include:

[0107] The lifting rod 20 is fixed on the outside of the pneumatic push rod 3;

[0108] The frame plate 21 is fixed to the outer side of the lifting rod 20, and a cover plate 28 is fixed to a side of the frame plate 21 away from the lifting rod 20;

[0109] A pull rope 19, one end of which is fixed to an end of the T guide plate 16 close to the T plate 15, and moves through the T plate 15 and the frame plate 21;

[0110] A spring 22, one end of which is fixed to the inner side of the frame plate 21 and is located outside the pull rope 19;

[0111] The pressure plate 23 is fixed to the end of the spring 22 away from the fixing plate 6 and is fixedly connected to the other end of the pull rope 19;

[0112] The adjusting part is arranged on the outside of the lifting rod 20 and is located at an end of the lifting rod 20 away from the frame 1 and is connected to the pressure plate 23 .

[0113] Specifically, one end of the guide frame 13 away from the T guide plate 16 is rotatably connected to the pulley 17, and the pull rope 19 is in contact with the pulley 17. A through hole 18 is opened inside the T plate 15, and the through hole 18 is located on the outside of the pull rope 19. The lifting rod 20 can provide a stable support for the frame plate 21 under the support of the support plate 2. The frame plate 21 can provide a through channel for the pull rope 19 and can stably support the spring 22, and the frame plate 21 can provide a stable support for the cover plate 28. The cover plate 28 cooperates with the frame plate 21 to provide space and guiding function for the spring 22 to move telescopically. The spring 22 has a certain elasticity and can be stretched or contracted and deformed under the action of external force, and the spring 22 can stably support the pressure plate 23. The pull rope 19 can pull the spring 22 downward to retract through the pressure plate 23 under the action of external force, and the elastic band can pull the spring 22 upward through the pressure plate 23 under the action of external force to extend, and pull the pull rope 19 upward through the pressure plate 23 to move.

[0114] Adjustment parts include:

[0115] An elastic rope 24, one end of which is fixed to a side of the pressure plate 23 away from the spring 22;

[0116] C plate 25, fixed on the outer side of the lifting rod 20;

[0117] The first semicircular plate 26 is movably mounted on the outer side of the C plate 25 and is located above the lifting rod 20 and is fixedly connected to the other end of the elastic rope 24;

[0118] The adjusting rod 27 is fixed on the outside of the first semicircular plate 26 and is located on the outside of the lifting rod 20;

[0119] The cover plate 28 is fixed to a side of the frame plate 21 away from the lifting rod 20 .

[0120] Specifically, the elastic rope 24 has a certain elasticity and can be stretched and extended under the action of external force, and its elastic force is the same as the elastic force of the spring 22. The lifting rod 20 can firmly support the C plate 25, and the C plate 25 can provide mobile support and guiding function for the first semicircular plate 26. The first semicircular plate 26 can provide support for the adjusting rod 27, and the elastic rope 24 can bend and deform under the action of external force.

[0121] In actual application of this embodiment, the staff can push the adjusting rod 27 in the direction close to the lifting rod 20 according to the actual situation, so that the adjusting rod 27 pushes the first semicircular plate 26 under the action of external force, so that the first semicircular plate 26 moves along the C plate 25 to the telescopic end position of the lifting rod 20, and moves away from the C plate 25 to fit on the telescopic end of the lifting rod 20. At the same time, the adjusting rod 27 will fit with the outer side of the lifting rod 20 to prevent the first semicircular plate 26 from continuing to move towards the direction close to the shield 40 after fitting with the telescopic end of the lifting rod 20. Then, the lifting rod 20 is controlled to extend, so that the lifting rod 20 is supported by the support plate 2 and uses the extension The retracted end pushes the first semicircular plate 26 upward, so that the first semicircular plate 26 moves upward and pulls the elastic rope 24, so that the elastic rope 24 uses external force to pull the pressure plate 23 upward. At the same time, the pressure plate 23 will pull the spring 22 upward and stretch under the action of external force and the support of the frame plate 21. At the same time, the pressure plate 23 will pull one end of the pull rope 19 under the action of external force, so that the pull rope 19 moves upward under the support of the guide frame 13 and the resistance of the pulley 17. At the same time, the pull rope 19 will use its own friction force to push the pulley 17 to rotate under the support of the guide frame 13 during the movement, so that the pull rope 19 moves more smoothly. At the same time, the pull rope 19 will pass through the through hole 18 to approach the slide The pull rope 19 moves in the direction of the pulley 17, so that the pull rope 19 uses the end away from the pressure plate 23 under the action of external force to pull the T guide plate 16, so that the T guide plate 16 moves along the guide frame 13 in the direction close to the connecting head 4 under the action of external force. At the same time, the T guide plate 16 drives the template 7 and the punching die 8 to move together through the fixed plate 6 under the action of external force, and passes through the through slot 39 to contact the fixed plate 6 and the template 7 fixed under the T plate 15, and pushes the T plate 15 to move along the T slot 14 in the direction close to the pulley 17 through the fixed plate 6 and the template 7 fixed under the T plate 15, so that the T plate 15 passes through the through slot 39 and moves to the inner side of the guide frame 13 close to the pulley 17, and moves to the inner side of the guide frame 13 close to the pulley 17 on the guide frame 13. Under the support of the frame 13, the T-plate 15 drives the fixed plate 6, template 7 and punching die 8 below it to move out from the inside of the frame 1 to the outside along the guide frame 13. At the same time, the T-guide plate 16 will be inserted into the inside of the T-slot 14 during the movement, and drive the fixed plate 6, template 7 and punching die 8 to move to the inside of the frame 1 along the T-slot 14 until the position of a template 7 is moved to replace the template 7 and punching die 8 moved out of the frame 1, so that the connector 4 can push the T-guide plate 16 downward under the action of external force, so that the T-guide plate 16 pushes the fixed plate 6, template 7 and punching die 8 below it downward under the action of external force to perform punching work;

[0122] Then, the staff can remove the fixing parts on the fixed plate 6 moved out of the frame 1 according to the actual needs, and then release the fixing effect on the template 7 moved out of the frame 1, and then use the template 7 to drive the punching die 8 fixed below it to be removed from the fixed plate 6, and replace the new template 7 and punching die 8, and use the fixing parts to fix them at the bottom of the fixed plate 6 for standby. After that, the staff can control the lifting rod 20 to retract as needed, release the tension on the first semicircular plate 26, the elastic rope 24, the pressure plate 23 and the pull rope 19, so that the spring 22 rebounds, and then push The template 7 fixed below the T-plate 15 enables the T-plate 15 to move along the guide frame 13 through the through slot 39 to the inner side of the frame 1, and at the same time, pushes the T-guide plate 16 to move in the direction away from the pulley 17 during the movement, and inserts it into the inner side of the T-slot 14. Under the support and guidance of the T-slot 14, the T-plate 15 drives the fixed plate 6, template 7 and punching die 8 at the bottom thereof to move to the inner side of the frame 1. At this time, the pushed T-guide plate 16 will drive the fixed plate 6, template 7 and punching die 8 below it to pass through the through slot 39 away from the pulley 17 and move out from the inner side of the frame 1 to the outside for replacement by the staff.

[0123] As a preferred embodiment of the present invention, the transmission member includes:

[0124] The insertion rod 29 is inserted through the first semicircular plate 26;
