Document Type and Number:
WIPO Patent Application WO/2020/253023
Kind Code:
A1
Abstract:
A novel hole punch for a hardware product, comprising a base (1), a support frame (2), a support plate (3), a cylinder (4), a telescopic rod (5), a hole punch body (6), a mold holder (7), a mold (8), a hole distance positioning frame (9), and a hole distance positioning sheet (10). The mold holder (7) is fixedly connected at the middle of the upper portion of the base (1), and the mold (8) is movably connected in the mold holder (7); the hole distance positioning frame (9) is arranged outside the mold holder (7), and the hole distance positioning sheet (10) is movably connected onto the hole distance positioning frame (9). The novel hole punch for a hardware product uses a rotatable mold, so that a hardware product can be punched twice without replacing the hole punch, and thus the utilization efficiency of the hole punch is improved.
