Abstract

The invention provides a drilling depth control device for an electric hand drill. The drilling depth control device comprises an inner connecting sleeve and an outer connecting sleeve mounted outsidethe inner connecting sleeve; the inner connecting sleeve is provided with spring assemblies, and the drilling depth control device further comprises a stabilizing sleeve mounted inside the outer connecting sleeve in a sleeved mode. According to the drilling depth control device, the inner connecting sleeve is provided with the spring assemblies, thus the number of circles of the spring assembliesreserved at the front end of the rear connecting end can be controlled according to the number of circles of the spring assemblies screwing into a connecting groove, and accordingly the drilling depth is positioned; and the outer connecting sleeve is connected with the stabilizing sleeve in a telescopic mode, thus the use length of the spring assemblies is protected, and the drilling depth control device is suitable for serving as standard parts to be produced, used and popularized.

Description

technical field [0001] The invention relates to the field of on-site construction, in particular to a drilling depth control device for a hand electric drill. Background technique [0002] In the drilling work, under special conditions such as the thickness of the drilling body is thin or in woodworking, it is necessary to control the drilling depth. The drill bits on the existing market do not have the function of controlling the depth. Therefore, it is necessary to design a A control device that can solve the above-mentioned deficiencies is provided. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to design a control device capable of controlling the drilling depth of an electric drill bit. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A drilling depth control device for a hand electric drill is provided, comprising an inner connecting ...
