The speed reduction mechanism is connected with a clutch mechanism. The output shaft of the motor is connected with a drive screw. The speed reduction mechanism comprises a rotating rod, a worm gear and a first bevel gear. The rotating rod is rotatably connected inside the shell mechanism. The worm gear and the first bevel gear are both sleeved on the outer wall of the rotating rod. The worm gear is engaged with the drive screw. The input end of the transmission mechanism is connected with a second bevel gear. The first bevel gear and the second bevel gear are engaged. The clutch mechanism comprises a push rod and a plurality of balls. The rotating rod is provided with a guide hole. The outer wall of the rotating rod is provided with a plurality of limiting holes which are in communication with the guide hole. The push rod is slidably connected with the rotating rod through the guide hole. The worm gear is rotatably connected with the rotating rod. The inner wall of the worm gear is provided with a plurality of positioning grooves which are matched with the balls. The balls are located between the outer wall of the push rod and the inner wall of the rotating rod. The push rod is used to drive the balls to partially extend out of the limiting holes and be clamped with the positioning grooves, or the push rod drives the balls to be separated from the positioning grooves. A spring is arranged in the guide hole. One end of the spring is connected with the inner wall of the rotating rod, and the other end of the spring is connected with the push rod. The clutch mechanism further comprises a clutch rod. The clutch rod is rotatably connected with the inner wall of the shell mechanism.
