Abstract

The invention relates to a power tool which comprises a main body (10) and an auxiliary handle (20), wherein the main body (10) comprises a shell (11), a working head (12) and a main handle (20); a motor is arranged in the shell (11); the auxiliary handle (20) is connected to the shell (11); the auxiliary handle (20) comprises an interconnecting piece (21) and a holding part (22); a wire (23) extends out of the inside of the interconnecting piece (21), and the wire (23) is connected to the motor in the shell (11); the inside of the holding part (22) forms a cavity (24); and at least part of abattery pack (25) is arranged in the cavity (24) and connected with the wire (23). In the invention, the battery pack is arranged in the auxiliary handle, so that the power tool effectively utilizes the space inside the auxiliary handle, reduces the size of the tool body and enhances the coordination of the entire tool without the additional battery pack.

Description

technical field [0001] The invention relates to a power tool, especially a hand-held power tool. Background technique [0002] Power tools can be divided into AC and DC according to their power sources, which are usually called corded and cordless in the industry. Among them, cordless power tools, that is, DC power tools, are generally equipped with a larger-sized battery pack, and the battery pack is connected to the power tool body. Once connected, the battery pack powers it for the application. [0003] Current battery packs are generally nickel-metal hydride or nickel-cadmium batteries, which are heavy in themselves. When the battery pack is connected to the power tool body which already has considerable weight, the resulting weight is even greater. Ordinary people will feel soreness and fatigue in their arms after operating power tools for a long time. The main reason is that the weight problem of cordless power tools has not been solved well. [0004] With the devel...
