Description

Technical Field

[0001] This utility model relates to the field of shoe upper repair, specifically to a shoelace hole punching device for shoe uppers. Background Technology

[0002] In the current footwear industry, some shoes are designed with relatively thin upper fabric to improve breathability and lightness. In addition, existing sports shoes usually use shoelaces to control the tightness of the shoe opening. Due to the thin upper fabric or poor tensile strength, the top shoelace eyelets of some shoes often break after a period of use. In order to facilitate the repair of shoelace eyelets, repair personnel need special shoelace eyelet punching equipment.

[0003] To facilitate drilling at any time, shoelace hole punching devices are usually portable manual shoelace hole punching machines similar to staplers. The upper and lower pressure blocks squeeze the shoelace holes, causing the punching pins above the upper pressure block to punch holes at the pre-drilled positions on the shoe upper.

[0004] Although this type of punching machine can punch holes in the shoe upper, after punching the holes, in order to avoid direct contact between the shoe upper and the shoelaces and thus improve tensile strength, eyelets are usually installed in that position. However, when installing eyelets, other tools are needed for fixation. Utility Model Content
