A motor is fixedly installed within the motor cavity. Two grooves are symmetrically formed on the top side of the concave base. Through holes are formed on the inner walls of both sides of the motor cavity, communicating with the grooves. A rotating shaft is rotatably installed within the through holes. One end of the rotating shaft near the motor cavity extends into the motor cavity and is fixedly connected to the motor's output shaft. The other end of the rotating shaft extends into the groove and is fixedly fitted with a first bevel gear. A sliding rod is slidably installed within the groove. A threaded groove is formed at the bottom end of the sliding rod, and a rotating rod is rotatably installed within the threaded groove.
