During the rightward movement, the right side groove surface of the L-shaped card slot and the left end of the size bar are initialized to be longitudinally aligned as the starting point, and the margin of the small holes for the stitches to be punched on the square piece is obtained by referring to the spacing of the right side groove surface of the L-shaped card slot that is retracted to the right.

[0024] The starting spacing adjustment member 4342 includes a starting spacing adjustment support 43421, and the starting spacing adjustment support 43421 is threadedly connected to a second screw adjustment member 43422, and the front end of the second screw adjustment member 43422 is provided with a distance stop block 43423 adapted to the punch layout sleeve groove 43411, and the left side of the distance stop block 43423 is engraved with a starting size chart 43424, and the initialization of the front end of the distance stop block 43423 is aligned with the rear side horizontal groove surface of the L-shaped positioning groove 3311.

[0025] The rotary locking member 4343 includes a rotating screw 43431 , and a pressing block 43432 is provided at the rear end of the rotating screw 43431 , and the pressing block 43432 is cylindrical, and an anti-wear pad 43433 is provided on the rear side of the pressing block 43432 , and the anti-wear pad 43433 is made of plastic.

[0026] The driving assembly 44 includes a driving shaft 441, and a plurality of bearings 442 are sleeved on the driving shaft 441. The rear end of the driving shaft 441 is transmission-connected to a motor 443. The front side of the driving shaft 441 is longitudinally connected to an eccentric pressure roller 444 that rotates against the surface of the pressure roller 435.

[0027] Each of the punch components 45 includes a punch sleeve 451, and two anti-drop edges 452 are arranged on the left and right sides of the punch sleeve 451, and a punch body 453 is vertically arranged in the middle of the bottom surface of the punch sleeve 451. The longitudinal thickness of the punch sleeve 451 is equal to the distance between two adjacent suture holes 51.

[0028] Working principle: First, according to the margin of the suture hole 51 to be punched on the cut piece 5, the margin adjustment mechanism 3 is adjusted to the right, and the first screw adjustment member 332 is rotated to make the clamping plate body 331 move right horizontally. During the rightward movement, the right side groove surface of the L-shaped clamping groove 3311 and the left end tail of the size horizontal strip 34 are initialized to be longitudinally aligned as the starting point, and the margin of the suture hole 51 to be punched on the square cut piece 5 is obtained by referring to the spacing of the right side groove surface of the L-shaped clamping groove 3311 shrinking to the right; It should be noted that after the above adjustment, since the lower end of each punch component is vertically aligned with the left end of the size bar 34, it is only necessary to compare the lateral spacing between the left end of the size bar 34 and the right side groove surface of the L-shaped clamping groove 3311 to obtain the lateral spacing between each punch component 45 and the right side groove surface of the L-shaped clamping groove 3311. Therefore, when the side of the square piece is to be punched, after being clamped on the right side groove surface of the L-shaped clamping groove 3311, each punch component 45 is vertically aligned and pressed down, and the required margin to be reserved for the suture holes 51 can be obtained, making the adjustment of the margin to be reserved for the suture holes 51 to be punched in the piece 5 very simple and quick.

[0029] Then, the starting distance adjusting member 4342 is adjusted according to the starting point of the suture small hole 51 to be punched on the cut piece 5, and the initialization of the front end of the fixed distance block 43423 is aligned with the rear side transverse groove surface of the L-shaped positioning groove 3311 as the starting point, and then the second screw adjusting member 43422 is twisted to make the fixed distance block 43423 slide forward at the rear end in the punch layout sleeve groove 43411, and refer to the forward distance of the starting size chart 43424 to confirm the positioning adjustment of the fixed distance block 43423 to the starting point of the suture small hole 51; It should be noted that when the cut piece 5 is to punch each stitch hole 51, a starting margin is required. However, it becomes very troublesome to directly refer to the vertical longitudinal spacing between the first punch member 45 at the last end and the rear side transverse groove surface of the L-shaped positioning groove 3311 as a reference for adjustment of the starting margin. However, through the engraving of the starting size chart 43424 on the left side of the fixed distance block 43423 of the present invention, the forward retracted spacing of the starting size chart 43424 can be directly referred to, and then half of the spacing of the punch sleeve 451 thickness can be subtracted, and the vertical longitudinal spacing between the first punch body 453 and the rear side transverse groove surface of the L-shaped positioning groove 3311 can be adjusted very conveniently.

[0030] Then, the number of punch pieces 45 required can be calculated according to the length of the suture holes 51 to be punched on the cut piece 5 by making the longitudinal thickness of the punch sleeve 451 equal to the spacing between two adjacent suture holes 51; It should be noted that the spacing between two adjacent stitching holes 51 to be punched on different cut pieces 5 is different. Therefore, the longitudinal thickness of the punch sleeve 451 on the punch member 45 of the present invention has multiple specifications. When each punch member 45 is assembled, the punch sleeve 451 with the same longitudinal thickness specification can be used for direct assembly, or the punch sleeves 451 with different longitudinal thickness specifications can be mixed and matched to obtain the desired spacing between the two stitching holes 51.

[0031] During installation, each punch component 45 is inserted into the punch layout sleeve groove 43411 in sequence at the loading and unloading port 43413, and each punch component 45 is squeezed and locked by extending backward at the front end of the punch layout sleeve groove 43411 to complete the layout installation of each punch component 45; It should be noted that when the punch component 45 is installed, the two anti-dropping edges 452 on the left and right sides of the punch sleeve 451 are stuck in the two Kara grooves 43412 on the left and right walls of the punch layout sleeve groove 43411, so the punch component 45 will not fall off. In addition, when the rotating screw 43431 on the spin-on lock 4343 is twisted backward, the pressure block 43432 is cylindrical and can directly move backward in the punch layout sleeve groove 43411 to press the front end of the punch component 45. The rear end of the pressure block 43432 also adopts a wear-resistant pad 43433 designed of plastic material, so that the spin-on lock 4343 uses a flexible pressure on the front end of the punch component 45, which is less likely to loosen.

[0032] Finally, the punching operation of the punching device is carried out. First, the cut piece 5 is placed on the punching plate 2, and the side of the cut piece 5 to be punched is clamped in the L-shaped clamping groove 3311, and then the foot switch 6 is stepped on to start the punching mechanism 4, and the eccentric pressure roller 444 is driven by the motor 443 to rotate one circle. During this process, the roller surface of the eccentric pressure roller 444 will spin downward against the pressing roller 435. Such spinning makes the whole row of punching parts 45 on the bottom surface of the punching plate group 434 more evenly stressed, so that the punching plate group 434 is vertically dropped between the two clamping slides 42, and the spring 433 is in a taut state, providing power for the automatic rise of the punching plate group 434. When the punching plate group 434 vertically drops to the lowest point, the whole longitudinal row of punching parts 45 will punch one side of the cut piece 5 to obtain a whole row of suture holes 51 on one side of the cut piece 5. The above-mentioned punching of the side holes of the cutting piece 5 is based on the premise that the side holes of the cutting piece 5 are flat and the square cutting piece 5 used in the square shape tool kit is suitable for the application in mass production, because mass production can punch one side of the cutting piece 5 in batches and then punch the other side, thus avoiding the frequent adjustment of the margin adjustment mechanism 3 and the starting spacing adjustment member 4342 on the punching device, and the frequent and repeated installation and adjustment of each punch member 45, thereby achieving efficient punching to obtain the suture holes 51.

[0033] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

During the rightward movement, the right side groove surface of the L-shaped card slot (3311) and the left end of the size horizontal strip (34) are initialized to be longitudinally aligned as the starting point, and the margin of the stitching holes (51) to be punched on the square cut piece (5) is obtained by referring to the spacing of the right side groove surface of the L-shaped card slot (3311) retracted to the right; Then, the starting distance adjusting member (4342) is adjusted according to the starting point of the suture hole (51) to be punched on the cut piece (5), and the initialization of the front end of the fixed distance block (43423) is aligned with the rear side transverse groove surface of the L-shaped positioning groove (3311) as the starting point, and then the second screw adjusting member (43422) is twisted to make the fixed distance block (43423) slide forward at the rear end of the punch layout sleeve groove (43411), and refer to the forward distance of the starting size chart (43424) to confirm the positioning adjustment of the fixed distance block (43423) to the starting point of the suture hole (51); Then, the number of punch components (45) required can be calculated according to the length of the stitching holes (51) to be punched on the cut piece (5), by making the longitudinal thickness of the punch sleeve (451) equal to the spacing between two adjacent stitching holes (51). During installation, each punch component (45) is inserted into the punch layout sleeve groove (43411) in sequence at the loading and unloading opening (43413), and each punch component (45) is squeezed, locked and fixed by extending the rotary locking component (4343) backward at the front end of the punch layout sleeve groove (43411), thereby completing the layout installation of each punch component (45); Finally, the punching operation of the punching device is performed. First, the cut piece (5) is placed on the punching plate (2), and the side of the cut piece (5) to be punched is clamped at the L-shaped clamping groove (3311). Then, the foot switch (6) is stepped on to start the punching mechanism (4). The motor (443) drives the eccentric pressure roller (444) to rotate one circle. During this process, the roller surface of the eccentric pressure roller (444) will rotate the pressure roller (435) downward, so that the punching plate group (434) vertically descends between the two clamping slides (42), and the spring (433) will be in a tight state to provide power for the automatic rise of the punching plate group (434). When the punching plate group (434) vertically descends to the lowest point, the entire longitudinal row of punching pieces (45) will punch one side of the cut piece (5) to obtain a whole row of suture holes (51) on one side of the cut piece (5).
