A kind of auxiliary shelf for electric drill to punch upwards

Abstract

The invention discloses an auxiliary frame used for upward drilling of an electric drill. The auxiliary frame comprises a base. A guide column is arranged on the base, a sliding sleeve is sleeved on the guide column and is connected with one end of a connection rod in rotating mode, the other end of the connection rod is connected with a press rod in rotating mode, the press rod is connected with the guide column in rotating mode, an electric drill fixing frame used for fixing the electric drill is fixedly arranged on one side of the sliding sleeve, a guide sleeve is fixed at the position of the base on one side of the guide column, the guide column is sleeved in the guide sleeve, a transparent cover body is fixedly arranged at the upper end of the guide column, and a screwing cap used for fixing a second guide column is arranged at the connection position of the guide column and the guide sleeve. In the drilling process, the electric drill passes through a cover body, a light source is arranged on the lateral wall of the cover body, and light emitted from the light source passes through intersection points of the electric drill tip and the end portion plane of the cover body. The auxiliary frame is capable of achieving accurate location of the drilling position under the condition that the height between a ceiling and the bottom face is higher or the top light of the ceiling is not good.

Description

technical field [0001] The invention relates to a support device for an electric drill, in particular to a shelf for the 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 view of the above defects, the patent authorization announcement number is "CN 201924573U", 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 hand-pressed bracket i...

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 all relatively high (the height of the general building floor is 2.8m~3.5m, and the higher one has 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
