Problems solved by technology

[0004] In the past work, when the electric drill was drilling, the skilled workers used their experience to control the drilling depth, and there would be situations where the depth was not suitable, which would bring quality problems to the work.
In addition, when most of the existing electric drills are not drilling, the drill bit is not easy to disassemble from the electric drill for storage, and the drill bit is exposed outside for a long time, without effective protection and storage, it is easy to cause damage to the drill bit

Embodiment Construction

[0030] The following description serves to disclose the present invention to enable those skilled in the art to carry out the present invention. The preferred embodiments described below are only examples, and those skilled in the art can devise other obvious variations.

[0031] like Figure 1-8 As shown, an embodiment of the present invention includes a housing 1 , a motor 2 , a drill bit 3 , a transmission part 4 , a limiting part 5 and a control button 6 .

[0032] The housing 1 is a pistol-shaped housing, and a plurality of anti-slip grooves 11 are provided on the outside of the housing 1 to increase the friction force when holding the electric drill and improve the safety performance.

[0033] The motor 2 is fixed on the motor base 21 through fixing screw holes, and the motor base 21 is installed on the housing 1 . The motor 2 is also provided with a buffer ring 22 facing the power conversion device 42. The buffer ring 22 is made of rubber. The buffer ring 22 is used t...

Abstract

The invention discloses a novel electric drill which comprises a shell, a motor and a drill bit and is characterized by also comprising a transmission part and a limiting part; the transmission part is rotatably connected with the motor and the drill bit to realize rotation of the drill bit along with the motor, so that rotation in the circumferential direction of the drill bit and displacement in the axial direction of the drill bit can be both performed; and the limiting part is movably arranged on the shell and is used for limiting the displacement amount of the drill bit to control the drilling depth, and thus the purposes that the drill bit gradually extends outsides as the drilling depth is increased during drilling to realize accurate control of the drilling depth, and when the electric drill is not used, the drill bit is in the electric drill to be protected are achieved.

Description

[0001] This application is a divisional application whose application number is 2015110041549 and the title of the invention is a new type of electric drill. technical field [0002] The invention relates to the field of electric tools, in particular to a novel electric drill. Background technique [0003] The electric drill is a commonly used power tool, and it is also the power tool product with the largest demand. The working principle of the electric drill is that the motor rotor of the electromagnetic rotary or electromagnetic reciprocating small-capacity motor performs magnetic field cutting and works, and drives the operating device through the transmission mechanism. The gear increases the power of the drill bit, so that the drill bit scrapes the surface of the object and penetrates the object better. [0004] In the past work, when the electric drill was drilling, the skilled workers used their experience to control the drilling depth, and there would be situations ...
