[0042] The working principle of the present invention is:

[0043] When the present invention is used, the anastomosis device mounting tube that needs to be punched is placed in the inner wall of the rubber mounting tube 8, and then the rotating arm 14 is rotated. The rotating arm 14 drives the blocking block 15 to seal the rubber mounting tube 8, and then the punching needle 3 is moved to the inside of the perforation 10 to prepare for punching. Then the driving motor 21 is started, and the driving motor 21 drives 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 is only necessary to increase the rotation speed of the driving motor 21 to vibrate 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 anastomosis device mounting tube;

[0044] 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 bars 23 to move, and the mounting bar 23 drives the rack 25 to abut against the card gear 26. When the rack 25 is engaged with the card gear 26 and abuts against the outer wall of the card gear 26, it moves back and forth. When the mounting bar 23 drives the rack 25 to abut against the outer wall of the card gear 26 and reset, since the tooth directions of the rack 25 and the outer wall of the card gear 26 are opposite, the rack 25 will enter the inner part of the mounting bar 23 when it resets. When the rack 25 drives the card gear 26 to rotate, the card gear 26 drives the card box 35 to rotate, and the card box 35 drives the third spring 38 to rotate through the card groove 36, and the third spring 38 drives the mounting round block 40 to rotate. When the gear 32 is pulled back, the gear 32 is pulled back and the engagement ball 39 is disengaged from the engagement with the engagement groove 36 and the engagement ball 39 is disengaged from the engagement with the engagement groove 36 and the engagement ball 39 is disengaged from the engagement with the engagement groove 36 and the engagement ball 39 is disengaged from the engagement with the engagement groove 36 and the engagement ball 39 is disengaged from the engagement with the engagement groove 36 and the engagement ball 39 is disengaged from the engagement with the engagement groove 36 and the engagement ball 39 is disengaged from the engagement with the engagement groove 36 and the engagement ball 39 is disengaged from the engagement with the engagement groove 36 and the engagement ball 39 is disengaged from the engagement with the engagement groove 36 and the engagement ball 39 is disengaged from the engagement with the engagement groove 36 and the engagement ball 39 is disengaged from the engagement with the engagement groove 36 and the engagement ball 39 is disengaged from the engagement with the engagement groove 36 and the engagement ball 39 is disengaged from the engagement with the engagement groove 36

[0045] As the recovery wheel 34 pulls the tension rope 12, the two sets of tension ropes 12 tighten all the extrusion ropes 11, and as the extrusion rope 11 is tightened, the extrusion rope 11 moves along the rubber hose on the outer wall of the extrusion bag 5 and the inner wall of the movable tube 16. 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 rope 11 can tighten and squeeze the extrusion bag 5. As the interior of the extrusion bag 5 is filled with iron sand, the extrusion bag 5 can squeeze the rubber mounting tube 8. The anastomosis device 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 squeeze the outer wall of the rubber mounting tube 8 more evenly, and the rubber mounting tube 8 squeezes the anastomosis device mounting tube more evenly. 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 movable plate 2 to move, and the movable plate 2 drives the punching needle 3 to punch the anastomosis device mounting tube through the perforation 10. When the punching needle 3 punches the anastomosis device mounting tube, the anastomosis device mounting tube is subjected to more even force and is not easily deformed.

[0046] Note that when the contact limit of the tension rope 12 is required, 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 will be disengaged from the connection with the outer wall of the threaded rod 30. At this time, the squeezing bag 5 will drive the squeezing rope 11 to reset due to its own elastic force, and the squeezing rope 11 will drive the corresponding tension rope 12 to reset, and the tension rope 12 will drive the recovery wheel 34 to rotate and reset.
