The utility model discloses a handheld rotary
skin tendering instrument, which belongs to the technical field of
skin tendering instruments and comprises a
skin tendering instrument body, three buttons are arranged on the front side of the skin tendering instrument body, a rotary head is arranged on one side of the skin tendering instrument body, and a protective device is connected outside the skin tendering instrument body. The front face and the back face of the skin tendering instrument body are both connected with fixing devices, and the protection devices are connected to the fixing devices. According to the handheld rotary skin tendering instrument, by arranging a fixed plate, a buffer plate, a baffle, a moving block, a telescopic rod, a pull-back spring and a fixed block, when the handheld rotary skin tendering instrument is collided and falls on the ground and the buffer plate makes contact with the ground, the buffer plate slides in the fixed plate, and meanwhile the buffer plate drives the moving block to apply pressure to the pull-back spring, so that the pull-back spring is compressed; and then the return spring applies elastic force to the moving block, and the elastic force drives the moving block to move, so that the moving block is quickly reset, and the problem that components in the rotating head are damaged is avoided.
