Multifunctional handheld electric drill structure

Abstract

The invention discloses a multifunctional hand-held electric drill structure, comprising: a U-shaped handle, an installation seat is arranged on the upper end of the U-shaped handle, a first guide rod is arranged at the upper end of the installation seat, and a first guide rod is arranged at the upper end of the U-shaped handle. A gun drill seat is arranged on the guide rod, and a series excitation motor is arranged in the gun drill seat. The motor shaft of the series excitation motor extends out of the gun drill seat and is connected with the drill bit, and the inside of the installation seat is symmetrical on both sides A first bearing seat is provided, a first screw rod is rotatably arranged in the first bearing seat, a first screw sleeve that cooperates with the first screw rod is arranged at the lower end of the gun seat drill, and the U-shaped handle is provided with a first screw sleeve. A second guide rod is arranged at the lower inner end of the motor, and a first servo deceleration motor is slid on the second guide rod. It is connected with the fast driving bevel gear.

Description

technical field [0001] The invention relates to a practical tool, in particular to a structure of a multifunctional hand-held electric drill. Background technique [0002] An electric drill is a commonly used power tool that uses electricity as power to drill holes. Types include hand-held drills, impact drills, etc. Among them, hand-held drills are light and easy to carry, and are suitable for conditions where the hardness of the target material is average. However, the current hand-held drills do not have the function of accurately controlling the drilling progress, and they mostly rely on the user's experience to control Drilling depth, when the hand-held drill is in contact with a smooth wall, it is easy to dislocate, the wall is uneven, and ordinary people can't see it with the naked eye, and when the drill encounters a wall with different hardness, the rotation speed cannot be adjusted. Work, highlighting many unnecessary troubles. Contents of the invention [0003...

AI Technical Summary

Problems solved by technology

[0005] The advantages of the present invention are: the drilling progress of the drill bit can be precisely controlled by using the scale, and the setting of the anti-skid pad can make the hand-held electric drill close to the wall surface of various materials, so that it is not easy to be misplaced during the working process, and at the same time The set of two infrared laser positioning lights can solve the situation when the wall is not vertical or uneven. By adjusting the speed of the drill bit, it can be applied to walls of different hardness.
