Problems solved by technology

Due to the high hardness of the building material and the uneven density distribution, the eccentricity of the drill bit may affect the orientation of the 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

The invention discloses a perforating device for building materials. The perforating device is used for perforating the building materials (94) below the perforating equipment and comprises a shell (91) used for abutting against a fixed object (9) at the upper part, two pressing screw assemblies (8) are installed on an upper side wall of the shell (91) and are symmetric around the longitudinal axis of the shell (91), and each pressing screw assembly (8) comprises a threaded fixed sleeve (82) fixed to the upper side wall of the shell (91) and a pressing screw (81) matched with a threaded hole (821) in a wall of the lower end of the threaded fixed sleeve (82) in a threaded mode.

Description

technical field [0001] The invention relates to a punching device, in particular to a punching device 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 building materials and the possible uneven density distribution, 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 punching device for building materials, which can overcome the defects in the prior art. [0004] A punching device for building materials according to the present invention is used to punch holes for building materials below, comprising a housing for abutting against an upper fi...
