Repairing clamp for adjusting mouth height of zipper head

Abstract

The invention discloses a repairing clamp for adjusting the mouth height of a zipper head. The repairing clamp comprises a left clamp body and a right clamp body which are hinged to each other, the left clamp body and the right clamp body are separately provided with a clamp head at one side of a hinged part and a clamp handle at the other side of the hinged part, a through groove is formed in theouter end of the left clamp head, and limiting structures are arranged on the right clamp head and between the left clamp head and the right clamp head respectively. During use, the limiting structure on the right clamp head conducts limiting on a lower panel of the zipper head, and the limiting structure between the left clamp head and the right clamp head limits the mouth height of an upper panel and the lower panel. According to the repairing clamp, through the arrangement of the limiting structure of the lower panel on the right clamp head, the situation that the lower panel moves in theprocess of squeezing the upper panel and the lower panel is avoided, and the upper panel and the lower panel are prevented from being twisted under pressure; and through the arrangement of the limiting structure with the mouth height between the left clamp head and the right clamp head, the situation that the upper panel and the lower panel are squeezed excessively is avoided, it is guaranteed that the upper panel and the lower panel are squeezed to the set mouth height value, and normal use of zippers is also guaranteed.

Description

technical field [0001] The invention relates to the field of zipper puller repair tools, in particular to a repair pliers for adjusting the height of the zipper puller. Background technique [0002] The use of zippers has penetrated into people's various daily lives. Basic zippers include fastener elements, zipper pullers, top stops and bottom stops, and zipper pullers usually include sliders, pull tabs and caps. During the transportation, sewing, washing and use of the zipper, it is easy to deform due to the opening height of the zipper, and the opening height becomes larger, resulting in bursting chains, meshing misalignment, etc., which affects the normal use of the zipper. [0003] Chinese utility model patent 201120408243.0 discloses a new type of zipper puller repair pliers, one side of the pliers mouth is the same as ordinary pliers, the other side of the pliers mouth is a concave pliers mouth, when repairing the zipper pull, the concave pliers mouth 4 side is placed ...

AI Technical Summary

Problems solved by technology

[0004] The applicant aims at the disadvantages of the above-mentioned existing zipper puller repair pliers, the lower fins are prone to shift during the extrusion process, and the upper and lower fins are easily squeezed too much, resulting in too small mouth height and affecting the normal use of the zipper. A kind of repair pliers with a reasonable structure for adjusting the height of the zipper head. The limit structure is set on the side where the lower flap is placed and the extrusion direction to avoid the displacement of the lower flap and the excessive extrusion of the upper and lower flaps, and ensure the extrusion Press to the set opening height to ensure the normal use of the zipper
