[0018] Preferably, the connecting block and the U-shaped frame are fixedly connected by bolts;

[0019] The U-shaped frame has a through hole on its outer transverse section, and the connecting block has a screw hole on its outer side. The bolt passes through the through hole, and the inner end of the bolt is threadedly connected to the screw hole.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. This utility model, by setting a connecting block, a U-shaped frame and a protective sheet, has the advantage that when the skin of the fingertip comes into contact with the protective sheet, it will not directly contact the front end of the zipper head, and the skin will not be pinched when pulling. It solves the problem that when the front end of the zipper head comes into contact with the finger, the skin of the fingertip is easily pinched during the pulling process.

[0022] 2. This utility model has the advantage of facilitating the insertion of the transverse section inside the U-shaped frame into the slot by setting an opening slot.

[0023] 3. This utility model has the advantages of positioning the U-shaped frame by setting bolts, through holes and screw holes, and facilitating the disassembly and replacement of the U-shaped frame and protective plate. Attached Figure Description

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0033] Example 1: A zipper pull with an anti-pinch structure, see [link / reference] Figures 1 to 4 It includes a chain head 1, a pull ring handle 2, a pull tab 3, and an anti-pinch structure 4; the pull ring handle 2 is rotatably connected to the chain head 1; one end of the pull tab 3 is fixed to the open end of the pull ring handle 2; the four anti-pinch structures 4 are respectively arranged at the upper and lower ends on both sides of the beginning of the chain head 1.

[0034] The anti-pinch structure 4 includes a connecting block 401, a U-shaped frame 402, and a protective plate 403; the connecting block 401 is fixed to the beginning of the chain head 1; the inner transverse section of the U-shaped frame 402 is inserted into and cooperates with the slot 4011 opened at the outer end of the connecting block 401; the protective plate 403 is fixed to the outer transverse end of the U-shaped frame 402; wherein, the protective plate 403 is inclined to correspond to the beginning of the chain head 1.

[0035] This utility model, by setting up a connecting block 401, a U-shaped frame 402 and a protective plate 403, has the advantage that when the skin of the fingertip contacts the protective plate 403, it will not directly contact the front end of the zipper head 1, and the skin will not be pinched when pulling. It solves the problem that when the front end of the zipper head contacts the finger, the skin of the contacting fingertip is easily pinched during the pulling process.

[0036] Specifically, the outer end of the connecting block 401 at the outer end of the slot 4011 is provided with an opening slot 4012. The opening slot 4012 is trapezoidal and is connected to the slot 4011. The opening of the opening slot 4012 is outward.

[0037] This utility model has the advantage of facilitating the insertion of the inner transverse section of the U-shaped frame 402 into the slot 4011 by setting an opening slot 4012.

[0038] Furthermore, the protective sheet 403 has an arc-shaped structure with the arched end facing outwards, so that the fingers will not feel uncomfortable when in contact with it.

[0039] Furthermore, the connecting block 401 and the U-shaped frame 402 are fixedly connected by bolts 404; wherein, the outer transverse section of the U-shaped frame 402 is provided with a through hole 4021, the outer side of the connecting block 401 is provided with a screw hole 4013, the bolt 404 passes through the through hole 4021, and the inner end of the bolt 404 is threadedly connected to the screw hole 4013.

[0040] This utility model, by setting bolts 404, through holes 4021 and screw holes 4013, has the advantages of positioning U-shaped frame 402, and facilitating the disassembly and replacement of U-shaped frame 402 and protective plate 403.

[0041] Working principle: Using the device of this utility model, the inner transverse section of the U-shaped frame 402 passes through the opening slot 4012 and is inserted into the corresponding slot 4011. The bolt 404 passes through the through hole 4021 and is screwed into the screw hole 4013, fixing the U-shaped frame 402 to the connecting block 401. At this time, the protective plate 403 is located at the front end of the chain head 1. When the skin of the fingertip contacts the protective plate 403, it will not directly contact the front end of the chain head 1, so it will not pinch the skin when pulling. When replacing the U-shaped frame 402 and the protective plate 403, loosen and remove the bolt 404, pull out the U-shaped frame 402, and install the new U-shaped frame 402 and the protective plate 403 in the same way as described above.

[0042] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
