The invention relates to a power tool. The power tool comprises an output head body and a working bottom plate, wherein the working bottom plate is detachably connected to the output head body; the output head body is provided with an output head matching structure, wherein the output head matching structure comprises output head matching teeth which extend along the circumferential direction at intervals, the working bottom plate is provided with a bottom plate matching structure, wherein the bottom plate matching structure comprises bottom plate matching teeth which extend along the circumferential direction at intervals; and each output head matching tooth can be inserted between the adjacent bottom plate matching teeth, the output head matching teeth are provided with output head matching tooth arc surfaces, and the bottom plate matching teeth are provided with bottom plate matching tooth arc surfaces matched with the output head matching tooth arc surfaces. According to the powertool, the output head body and the working bottom plate are matched to drive the working bottom plate to swing through the bottom plate matching structure and the bottom plate matching structure; andthe output head matching teeth are matched with the bottom plate matching teeth through the bottom plate matching tooth arc surfaces and the output head matching tooth arc surfaces so that compared with plane match, the effect of eliminating gaps and transmitting torque can be achieved.
Description
technical field [0001] The invention relates to the field of hand-held tools, in particular to a power tool. Background technique [0002] With the development of society and the advancement of science and technology, power tools such as sanders are widely used in people's production and life, and people's requirements for the work efficiency and processing quality of power tools are also increasing. [0003] At present, the connecting structure of the working base of power tools such as sanding machines and the connecting structure of the output head are provided with toothed structures to engage with each other, so that the working base is installed on the output head and is easy to disassemble for replacing the working base. However, due to structural defects, there is often a certain gap between the working base plate and the intermeshing toothed structures on the output head, which affects the torque transmission effect and ultimately affects the working efficiency and ...
