Description

Technical Field

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

[0002] During the construction process, it is often necessary to drill holes in the external wall. At present, for the wall drilling operation, usually the staff holds an electric drill to complete the drilling operation on the wall. The structures of existing electric drills are mostly relatively simple, generally composed of a machine body, a drill bit and a handle. A driving unit is installed in the machine body, which provides power for the drill bit to rotate, so as to drill holes in the wall, and the handle is used for the staff to hold the drill for operation.

[0003] During the drilling operation on the wall, the electric drill will bring out a certain amount of powder. However, these powders usually directly fall along the wall. Since the drilling has a certain height, during the falling process, the powder will not only adhere to the wall and be difficult to clean, but also easily spread into the air and be inhaled by people; and when drilling, the staff needs to hold the electric drill by hand and make the drill bit perpendicular to the wall. This method can only be evaluated by the user's feeling whether it is perpendicular, and in actual drilling, the electric drill is prone to tilt, resulting in incorrect drilling positions. Therefore, an external wall drilling device for construction engineering construction is provided to solve the above problems. Summary of the Utility Model
