The function box 3 is driven to move up and down through the second lifting device. The second lifting device can use a first electric push rod 33, and the function box 3 is set on the lower end of the movable part of the second lifting device. Through the function box 3, a mounting carrier is provided for components such as the rotating shaft 35. Then, two telescopic rods 34 located on the front and rear sides of the second lifting device are symmetrically installed between the function box 3 and the vehicle plate of the mobile vehicle 2. The two telescopic rods 34 are used in combination to guide the movement of the function box 3.

[0041] The rotating shaft 35 is rotatably connected to the inside of the function box 3, and a mounting carrier is provided for the large bevel gear 36 through the rotating shaft 35, and the fixing part of the third driving device connecting the output shaft with the rotating shaft 35 is arranged on the front end of the function box 3, and the rotating shaft 35 is driven to rotate through the third driving device.
