Two movable blocks 9 are symmetrically threaded on the outer wall of the bidirectional threaded rod 8, and a connecting plate 10 is hinged on the top surface of the movable block 9.

[0027] The refueling mechanism includes a cam 16 and a refueling cylinder 17, and the cam 16 is fixedly connected to the rotating shaft of the first sprocket 1;

[0028] The refueling cylinder 17 is fixedly connected to the front side of the mounting plate 4, the inner wall of the refueling cylinder 17 is sealingly and slidably connected with a piston 18, the left middle part of the piston 18 is fixedly connected with a piston rod 19, the other end of the piston rod 19 extending to the outside of the refueling cylinder 17 is in contact with the side of the cam 16, a positioning plate is fixedly connected to the outer wall of the piston rod 19 located outside the refueling cylinder 17, and a return spring is sleeved on the outer wall of the piston rod 19 located between the positioning plate and the refueling cylinder 17.
