Anti-inclination adjusting drill bit for constructional engineering

Abstract

The invention relates to the technical field of constructional engineering, and discloses an anti-tilt adjusting drill bit for constructional engineering, which comprises a shell, an indicator light fixedly connected to the inner wall of the middle of the shell, a piezoresistor fixedly connected to the inner wall of the middle of the shell, a feeler lever movably connected to the inner wall of the middle of the shell, and a drill rod movably connected to the inner wall of the middle of the shell. The middle inner wall of the drill rod is fixedly connected with a dielectric plate. According to the anti-inclination adjusting drill bit for constructional engineering, the negative plate is driven to move through the feeler lever, the feeler lever drives the negative plate to move, then through cooperative use of the piezoresistor and the indicator lamp, the effect of warning inclination of the drill bit is achieved, in the drilling process, the initial relative area can be changed when any one of the negative plate and the dielectric plate deviates, and therefore the drill bit is prevented from inclining. Therefore, the minimum relative area is changed, the piezoresistor cannot reach the minimum path voltage, the indicator lamp is in an open-circuit state, and an operator is warned of inclination of a drill hole.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an anti-tilt adjusting drill bit for construction engineering. Background technique [0002] Construction engineering refers to the engineering entity formed through the construction of various housing buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. During the construction process, it is often necessary to drill holes in the walls and ground. Most of the electric drills for wall drilling are handheld, and they are widely used in the construction process due to their convenience. [0003] Most of the existing drilling equipment is to apply pressure to the drill bit by hand. Due to the vibration of drilling, it is easy to cause sore hands, it is difficult to maintain a uniform posture, it is difficult to grasp the balance of the drill pipe, and it is easy to cause deviations in the depth of the blind hole...
