Problems solved by technology

Therefore, the punching time of each ventilation hole is longer, and the labor intensity is very large.
And during drilling, it is necessary to keep the cutter head stable, when the cutter head is not stable, it will cause the cutter head to break

Abstract

The invention discloses a building wall perforating device which comprises a connecting piece connected with a wall; an expansion bolt is matched between the connecting piece and the wall; the connecting piece is matched with a main hack lever; a hinge pin is matched between the main hack lever and the connecting piece; the main hack lever can rotate by taking the hinge pin as a rotary central point; a screw is screwed in the top of the connecting piece; after the screw is screwed in, the screw is propped against the main hack lever, and at the moment, the main hack lever is fixed; and a strip-type groove is formed in the top of the main hack lever. The building wall perforating device is easy to operate and high in perforating precision.

Description

technical field [0001] The invention relates to a wall opening device for building. Background technique [0002] In building construction, punching holes in walls is a very routine operation, but the diameter of ordinary air-conditioning holes is usually only about 10cm, and the punching operation is relatively simple. But the ventilation hole of large-scale wall body fan, its hole diameter is more than 30cm, and under the height of the same column, it is necessary to drill a plurality of ventilation holes. [0003] The existing way of punching this type of large hole is still based on manual operation. The operator needs to hold a larger punching device with a large cutter head for punching, and because the amount of feed each time is small. Therefore, the punching time of each ventilation hole is longer, and the labor intensity is very large. And during drilling, it is necessary to keep the cutter head stable, when the cutter head is not stable, it will cause the cutte...
