Drilling device

Abstract

The invention discloses a drilling device. The drilling device comprises a base and a guide post arranged on the base, wherein a sliding sleeve is sleeved on the guide post, an electric drill fixing rack for fixing an electric drill is fixedly arranged on one side of the sliding sleeve, the sliding sleeve transmits through a compression bar link mechanism, a guide sleeve is fixed on the side of the guide post on the base, a guide post is sleeved in the guide sleeve, and a transparent cover is fixed at the upper end of the guide post. During drilling, the electric drill passes through the cover, a first light source is arranged on the side wall of the cover, light rays emitted by the first light source pass through the intersection of the tip of the electric drill and the cover end plane, a dividing rule is arranged at the end of the cover, a second light source is arranged on the electric drill, and light rays emitted by the second light source, the electric drill head and the dividing rule are in the same plane. By means of the drilling device, the electric drill can drill in ceilings vertically, horizontal offset can be avoided, the drilling accuracy is guaranteed, and the drilling depth is controllable.

Description

technical field [0001] The invention relates to a punching device, in particular to a device for punching a ceiling with a hand-held electric drill. Background technique [0002] When drilling holes in the ceiling with a hand-held electric drill, the general operation is: first set up the ladder, and then the worker climbs up the ladder and uses a hand-held electric drill to drill holes in the ceiling. It is very difficult to operate because the construction workers have to tilt their heads and force upwards. At the same time, it is necessary to stand on the scaffold or step on the ladder, which greatly affects the stability and safety during the operation. [0003] In response to the above defects, the patent authorization announcement number is "CN 201924573 U", and the name is "upward drilling auxiliary device for impact electric drill". There is a hand-pressed bracket under the pole, and a fixed impact electric drill device is installed on the top of the pole. The han...

AI Technical Summary

Problems solved by technology

Causes the holes drilled in the ceiling to be in the form of strips without the use of bolts or screws in the through-holes

And for the above-mentioned mechanism to directly press down the pressure rod to jack up the electric drill, it is easy to cause the drilling depth to be difficult to control, so it is necessary to improve it
