Power supply structure of electric grinding machine tool

Abstract

The invention discloses a power supply structure of an electric grinding machine tool. The power supply structure comprises an electric power management module, an electric power connecting wire and a battery socket, wherein the electric power management module is arranged on an electric grinding machine tool body; the electric power connecting wire is electrically connected with the electric power management module and extends out of the electric grinding machine tool body; the battery socket is connected with the electric power connecting wire and can change the position at will based on the electric power connecting wire; a replaceable battery is selectively arranged on the battery socket; and the battery socket is provided with a guide sliding groove and at least two conductive terminals, wherein the guide sliding groove is formed corresponding to a boss on the replaceable battery, and the conductive terminals are arranged in the guide sliding groove. By changing the power supply structure of the electric grinding machine tool, a user can hold the electric grinding machine tool body, so that the weight on the hand can be greatly reduced, the optimal working quality during grinding operation can be easily achieved, and meanwhile, the working injury can be avoided.

Description

technical field [0001] The invention relates to a power supply structure, in particular to a power supply structure of an electric grinding tool machine. Background technique [0002] Due to the continuous progress of brushless motors and lithium-ion batteries, traditional plug-in hand-held tools (Corded HandHeld Tools) are gradually being replaced by battery-powered tools (Battery Powered Tools). However, most battery-driven tools, such as electric drills, electric screwdrivers, and chainsaws, are used intermittently, or the power consumption of these machine tools is not large, and the battery is sufficient to supply the power required by the machine tool. However, there are some tools that consume a lot of electricity and are mostly used continuously for a long time, such as grinders or waxing machines. These types of machine tools need to supply power for a long time and in large quantities, and the existing batteries are difficult Meet the power requirements of these m...
