The second motor is fixedly connected to the middle of the top surface of the housing, the first pulley is fixedly connected to the output shaft of the second motor, and the bottom end of the belt is sleeved inside the first pulley.

[0008] Preferably, the tensioning assembly includes an electric telescopic rod, a pressure sensor, a first mounting bracket, and a second pulley. The electric telescopic rod is fixedly connected to the top surface of the fixed bracket, and the telescopic end of the electric telescopic rod passes through the fixed bracket and is fixedly connected to the pressure sensor. The first mounting bracket is fixedly connected to the bottom surface of the pressure sensor, and the second pulley is rotatably connected to the bottom of the inner side of the first mounting bracket.
