Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing:

[0017] As shown in the figure, an electric drill anti-overload device consists of a turntable 1, a spindle 2, a drill bit 3, a spring 4, a contact body 5, a large button 6, a small button 7, a contactor system 8, an electric system 9, a gear system 10, Line 11, fixed track 12, contact shrapnel 13, lubricant container 14, lubricant delivery pipe 15.

[0018] The turntable 1 is connected to the main shaft 2, the drill bit 3 is connected to the main shaft 2, one end of the spring 4 is connected to the turntable 1, and the other end of the spring 4 is connected to the contact body 5;

[0019] The contact body 5 has two pieces, the contact spring 13 is in contact with the turntable 1, the lower half of the turntable 1 is connected to the power supply through the contact spring 13, the upper half of the turntable 1 is connected to the small button 7 through the contact spring 13,...

Abstract

The invention relates to an electric drill overload protector comprising a turnplate, a spindle, a drill bit, a spring, a contact member, a large button, a small button, a contactor system, an electric system, a gear system, a circuit, a fixed rail, a contact spring plate, a lubricant container, and a lubricant pipeline. The electric drill overload protector can automatically power off an electric drill in case of overloading, so that a motor is protected from burnout and the service life a machine is prolonged. The drill bit can be lubricated constantly. The electric drill overload protector is simple to operate, convenient to use and easy to popularize.

Description

technical field [0001] The invention relates to an overload prevention device, in particular to an electric drill overload prevention device. Background technique [0002] A drilling tool powered by electricity. It is a conventional product in electric tools, and it is also the most demanded electric tool product. 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, drives the working device through the transmission mechanism, and drives the gear to increase the power of the drill bit, so that the drill bit scrapes the surface of the object and penetrates the object better. . The electric drills that appeared in the early days mainly include DC electric drills, three-phase power frequency electric drills, single-phase series motor-driven electric drills, intermediate frequency electric drills, battery electric drills, and electronic ...
