Vertical drilling assisting electric drill frame for handheld electric drill

Abstract

The invention relates to a vertical drilling assisting electric drill frame for a handheld electric drill. The vertical drilling assisting electric drill frame comprises a base, a first guide sleeve and a second guide sleeve are abreast arranged on the base, a first guide column is slidably arranged in the first guide sleeve, an electric drill holder used for fixing the electric drill is arranged at the end of the first guide column, and a push rod is arranged on the side wall of the first guide column. The side wall of the first guide sleeve starts from a push rod groove matched with the push rod, a second guide column is sleeved in the second guide sleeve, a transparent cover is fixedly arranged at the upper end of the second guide column, and a screw nut used for fixing the second guide column is arranged at the joint of the second guide column with the second guide sleeve. During drilling, the electric drill passes through the cover which is provided with a light source on the side wall, and light emitted by the light source passes through the point of intersection of the centre of the electric drill and the plane of the cover end. Horizontal movement of a drill bit of the electric drill is prevented when the drill bit of the electric drill moves vertically, and accuracy in positioning is achieved.

Description

technical field [0001] The invention relates to a supporting device for a hand-held electric drill, in particular to an auxiliary electric drill stand for vertical drilling of the 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 dr...

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 because the top surface of the general ceiling is relatively high (the height of the general building floor is 2.8m~3.5m, and the higher one is about 4.0m~4.5m). The positioning of the top surface of the ceiling needs to be determined by visual inspection, and the position determination is prone to deviation, especially at night or when the light on the top of the ceiling is poor, positioning is particularly difficult
