[0007] With the above technical solution, the base assembly is convenient for playing a supporting role. During use, the first connecting plate and the third connecting plate are rotated through a rotating bearing, so that the position of the first connecting plate is adjusted to the bayonet of the drawbar base, and then the vertical plates on both sides of the first connecting plate are snapped into the corresponding bayonets on the drawbar base; the drawbar body penetrates through the hole, and the lower part of the drawbar body is fixed to the clamping component, so that the clamping component is clamped to the lower part of the third connecting plate; the telescopic component extends, so as to increase the distance between the first connecting plate and the third connecting plate.

[0016] Preferably, openings are provided through the two vertical plates.

[0017] With the above technical solution, the openings provided through the vertical plates are convenient for observing the separation condition of the towing pin body.

The lower part of the elastic member is fixed to the upper part of the lifting mechanism, the lower part of the lifting mechanism is fixed to the vehicle frame, and the several positioning components are arranged on both sides of the vehicle frame.

[0019] With the above technical solution, the lifting mechanism is convenient for adjusting the height of the first limiting plate and the like, so that the vertical plate is clamped into the towing pin base and the towing pin body is just inserted into the hole.

[0020] Preferably, several rollers are arranged at the lower part of the vehicle frame, and a handrail is also arranged on one side of the vehicle frame.

[0021] With the above technical solution, the arrangement of the handrail and the rollers is convenient for the transportation of the vehicle frame.
