Dustproof electric drill

Abstract

The invention provides a dustproof electric drill. The dustproof electric drill comprises a shell, a power output device including an output shaft, a drill bit, a drill bit control device arranged in the shell, and a dustproof device, wherein the drill bit is mounted on the drill bit control device; the power output device outputs power to the drill bit control device through the output shaft; the drill bit control device is suitable for converting the rotation of the output shaft to the rotation and a linear motion; the rotation and the linear motion are synchronously output to the drill bit; the dustproof device comprises a dustproof cover, an elastic cover, a shaping frame and a connecting sleeve; the connecting sleeve is mounted on the shell in a forward and backward movable manner, and has a drill bit cavity with front and back openings; the drill bit penetrates through the opening in the back end of the drill bit cavity, and extends outside the opening in the front end of the drill bit cavity; the dustproof cover, the shaping frame and the elastic cover are mounted at the front end of the connecting sleeve in sequence from outside to inside; the shaping frame comprises at least three shaping pieces; each shaping piece is rotationally mounted at the front end of the connecting sleeve in the periphery; and the dustproof cover is arranged at the front end of the connecting sleeve in a forward and backward movable manner.

Description

technical field [0001] The invention relates to the field of electric drills, in particular to a dust-proof electric drill. Background technique [0002] Electric drills are commonly used equipment in production and life. They are mainly used to drill holes in various materials, but there are many problems in traditional electric drills. For example, when an electric drill drills a hole, a large amount of dust will be generated. With the rotation of the drill bit, the dust will fly in the air and will be inhaled by the operator, greatly affecting the health of the operator. In addition, the traditional electric drill does not have the function of positioning the drilling depth, that is to say, the user cannot accurately locate the drilling depth, but can only estimate whether the drilling meets the requirements based on experience, which causes the inconsistency of the drilling depth. , which affects the subsequent steps. In addition, the traditional electric drill does no...

AI Technical Summary

Problems solved by technology

For example, when an electric drill drills a hole, a large amount of dust will be generated. With the rotation of the drill bit, the dust will fly in the air and will be inhaled by the operator, which will greatly affect the health of the operator.

In addition, the traditional electric drill does not have the function of positioning the drilling depth, that is to say, the user cannot accurately locate the drilling depth, but can only estimate whether the drilling meets the requirements based on experience, which causes the inconsistency of the drilling depth. , which affects the subsequent steps

In addition, the traditional electric drill does not have supporting equipment, and the strong vibration generated by the electric drill may cause the drilling to be skewed and the drill bit to break, etc.
