Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction, in particular to a drilling device for construction. Background Art

[0002] Engineering construction refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. In the process of engineering construction, it is often necessary to punch holes in the plate using a punching device.

[0003] When the existing drilling device for construction is used to drill holes in the building wall, the drill bit rotates at high speed to drill into the wall, and the stability during drilling is poor, which can easily cause the drill bit to slip. If the drill bit is not perpendicular to the wall, it is easy to cause the drill bit to tilt during drilling. In addition, powder generated by drilling flies everywhere and enters the glasses and body of the workers, affecting their health. Therefore, a drilling device for construction is proposed to solve the above-mentioned problems. Utility Model Content
