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 which comprises a shell, a motor and a drill bit. The novel electric drill is characterized by further comprising a transmission part and a limiting part; the transmission part is connected with the motor and the drill bit in a transmission mode so as to achieve rotation of the drill bit along with the motor, and the drill bit not only can rotate in the circumferential direction of the drill bit, but also can shift in the axial direction of the drill bit; the limiting part is movably arranged on the shell and used for limiting the displacement amount of the drill bit so as to control the drilling depth. In this way, the drill bit gradually extends out with deepening of the drilling depth in the drilling process, so that the drilling depth is accurately controlled. As the drill bit is located in the electric drill when the electric drill is not used, the purpose of protecting the drill bit is 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 ...
