[0025] A plurality of linkage blocks 206 are equidistantly arranged on the linkage plate 205 . The shapes and sizes of the linkage blocks 206 are the same as those of the polygonal blocks 204 .

[0026] By rotating the screw 203, we can make the V-shaped frame perform a circular motion with the screw 203 as the center. In this process, the guide block 2031 will slide in the short groove 2041, thereby pushing the polygonal block 204 to move laterally along the slide groove. In this way, we can place the position of the punch 3 in advance. Through the joint action of the above components, we can complete the positioning assembly of the punch 3;

[0027] If the punching needle 3 needs to be removed, just reverse the operation, which is a very simple and practical process. In addition, the short groove 2041 design on the polygonal clamping block 204 not only reduces the risk of parts getting stuck, but also utilizes the cooperation of the linkage block 205 and the linkage clamping block 206 to install several groups of punching needles 3 at the same time.

[0031] By rotating the deep-groove screw 402 on the anti-slip sleeve, extrusion occurs between the inner part 404, the outer part 403 and the inner wall of the columnar shell 405, so that the square pad of the outer part 403 protrudes from the square opening and contacts with the outer wall of the punch needle 3 to form a clamping structure; through the auxiliary component 4, the punch needle 3 can be extruded and reinforced to prevent the punch needle 3 from bending and breaking during the punching process.

[0032] As the third embodiment of the present application, the technical solution of this embodiment is to combine the solutions of the above two embodiments for implementation.

[0033] The working principle of the utility model is as follows: by rotating the screw 203, the V-shaped frame makes a circular motion with the screw 203 as the center, and the guide round block 2031 slides in the short groove 2041, thereby pushing the polygonal block 204 to move laterally along the slide groove, and the position of the punching needle 3 is placed in advance. Through the joint action of the above components, the positioning assembly of the punching needle 3 is completed, and the reverse operation can complete the disassembly of the punching needle 3;

[0034] By rotating the deep-groove screw 402 on the anti-slip sleeve, extrusion occurs between the inner part 404, the outer part 403 and the inner wall of the columnar shell 405, so that the square pad of the outer part 403 protrudes from the square opening and contacts the outer wall of the punch needle 3 to form a clamping structure.

[0035] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
