Problems solved by technology

Due to the high hardness of the building material and the uneven density, the eccentricity of the drill bit may affect the orientation of the punching hole when drilling
Moreover, the structure of the punching device often results in larger external dimensions, making it difficult to form a compact structure and difficult to fix and position

Abstract

A puncher used for building materials is used for punching the building materials (94) arranged below the puncher. The puncher comprises a shell (91) used for abutting against an upper fixed object (9). Two stressing screw assemblies (8) are mounted on the upper side wall of the shell (91) and symmetrically arranged with respect to the longitudinal axis of the shell (91). Each stressing screw assembly (8) comprises a threaded fixing sleeve (82) and a stressing screw (81), wherein the thread fixing sleeve (82) is fixed to the upper side wall of the shell (91), and the stressing screw (81) is in threaded fit with a threaded hole (821) formed in the lower end wall of the threaded fixing sleeve (82).

Description

technical field [0001] The invention relates to a punching device, in particular to a puncher for building materials. Background technique [0002] The punching device for building materials often needs to open holes with larger apertures. Due to the high hardness of the building material and the uneven density, the eccentricity of the drill bit may affect the orientation of the drilling when drilling. Moreover, the structure of the punching device often results in relatively large external dimensions, making it difficult to form a compact structure and difficult to fix and position. Contents of the invention [0003] The object of the present invention is to provide a hole punch for building materials which overcomes the disadvantages of the prior art. [0004] A hole puncher for building materials according to the present invention is used to punch holes in the building materials below, and includes a housing for abutting against the upper fixture, and two holes are in...
