Abstract

The invention discloses a brake assembly, an electric tool switch and an electric tool, the brake assembly is partially arranged in the electric tool switch, is used for short circuit of a terminal D connected with a motor and a main loop terminal in the electric tool switch, and comprises a push rod, a brake pad and a brake spring, the brake pad is installed on the push rod, and the brake spring is installed on the brake pad. The brake spring is arranged between the brake pad and the push rod, the brake pad comprises a short circuit part, the brake pad has an initial state and a brake state, and when the brake pad is in the initial state, the short circuit part is obliquely arranged towards the side close to the D terminal; when the brake pad is in a braking state, the short circuit part and the push rod are arranged in parallel, and the short circuit part abuts against the D terminal and the main loop terminal. The brake assembly can prolong the brake service life of the electric tool switch and prolong the service life of the electric tool. Correspondingly, the invention further provides an electric tool switch and an electric tool.

Description

technical field [0001] The invention relates to the field of electric tools, in particular to a brake assembly, an electric tool switch and an electric tool. Background technique [0002] In order to ensure the safety of the electric tool, when the electric tool switch is disconnected, the electric tool is required to stop immediately with the disconnection of the tool switch, so as to prevent the motor of the electric tool from continuing to work under the action of inertia after the electric tool is disconnected, causing harm to the human body. Therefore, general electric drills, electric wrenches, electric saws, electric hammers and other electric tools will require the electric tool switch to have a brake function. When the whole machine needs to stop immediately, the switch brake will stop the electric tool immediately. [0003] The braking method of existing electric tools is that when the switch of the electric tool returns from the working position to the braking pos...
