[0004] Patent No. CN207234626U discloses a flat position positioning device for output flat shaft of reduction motor, which includes a mounting base, a reduction motor fixing seat, a connecting plate, a baffle, a test flat shaft, a detection sensor and a socket. The reduction motor fixing seat is arranged on the mounting base, and has a reduction motor accommodating groove. The connecting plate is arranged on the mounting base and located on one side of the reduction motor fixing seat. The baffle is arranged on one end of the mounting base. One end of the test flat shaft penetrates through the connecting plate corresponding to the reduction motor accommodating groove, and the other end is connected to the baffle through a spring. The detection sensor is arranged on the test flat shaft and connected to the connecting plate through a metal spring. The socket is arranged on the reduction motor fixing seat.
