Problems solved by technology

[0003] 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

[0029] 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.

[0030] Such as 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 .

[0031] 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.

[0032] 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 use...

Abstract

The invention discloses a novel electric drill. The novel electric drill comprises a shell body, a motor and a drill bit. The novel electric drill is characterized by further comprising a transmissionpart and a limit part, wherein the transmission part is connected with the motor and the drill bit in a transmissible manner, so as to realize the rotation of the drill bit 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 carried out; and the limit part is movably arranged on the shell body, and usedfor limiting the displacement amount of the drill bit, so as to control a drilling depth. Therefore, the purposes that the drill bit gradually stretches out with the increasing of the drilling depthduring drilling, so that the drilling depth is accurately controlled, and the drill bit is located in the electric drill when the electric drill is not used, so that the drill bit is protected are achieved.

Description

technical field [0001] The invention relates to the field of electric tools, in particular to a novel electric drill. Background technique [0002] 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. [0003] 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 ...
