Electric drill

Abstract

The invention discloses an electric drill. According to the technical scheme, the electric drill is characterized by comprising a shell and a drill chuck, wherein a motor is arranged in the shell andis used for driving the drill chuck to rotate; the drill chuck can be used for clamping a drill bit; a side wall, close to the drill chuck, of the shell is an installation wall; a sliding chute is formed in the installation wall; a control piece is slidably connected into the sliding chute, and can slide toward one side of the drill chuck; a limiting piece is arranged in the sliding chute, and isused for limiting a sliding position of the control piece; after the control piece moves to an ideal position, the limiting piece can limit the sliding position of the control piece; during an actualelectric drill use process, the motor drives the drill chuck to rotate, and the drill bit further rotates so as to drill into a corresponding wall surface; and when the end part of the control piece abuts against the corresponding wall surface, the motor stops working, the electric drill stops working, and only the drill bit needs to be pulled out from the wall surface, so that the depth accuracyof a hole drilled by the drill bit can be accurately controlled, and the building construction quality can be further effectively improved.

Description

technical field [0001] The invention relates to a drilling tool, in particular to an electric drill. Background technique [0002] Electric drills are commonly used drilling tools in building construction. [0003] The common structural features of electric drills, such as the Chinese invention patent application with the notification number CN101758269A, include a housing, and the housing includes a handle for the user to hold, a torque cover, and a drill chuck. The drill bit will be clamped in the drill chuck. Inside the housing The control motor will drive the drill chuck to rotate, and the drill chuck will drive the drill bit to rotate in a circumferential direction, and the drill bit can drill holes on the corresponding wall. [0004] However, in actual use, most of the objects used for electric drills are walls, and the texture is relatively loose. The operator's proficiency directly determines the accuracy of the drilling depth of the electric drill. This will affec...
