Preferably, two primary hydraulic cylinders 3031 are arranged, and the sleeve 3032 is movably connected to the top of the two primary hydraulic cylinders 3031, so as to ensure the reliability and stability of the operation. With the driving of the primary hydraulic cylinder 3031, the sleeve 3032 is lifted or lowered in the height direction of the trolley, the hoisting arm 304 moves relative to the movable hole of the sleeve 3032, that is, the hoisting arm 304 rotates relative to the hinged seat 2, so as to realize the lifting of the hoisting arm 304. It is to be noted that the lifting of the sleeve 3032 in the height direction of the trolley can be upward and downward movement perpendicular to the ground, or can be inclined movement relative to the ground to realize the change of height. The driving axis of the primary hydraulic cylinder 3031 is preferably perpendicular to the ground, so as to improve the structural stability.

[0027] Specifically, the sleeve 3032 is L-shaped, that is, the sleeve 3032 comprises a connecting seat and a guide cylinder, the connecting seat is movably connected to one end of the primary hydraulic cylinder 3031 away from the base 301, and the guide cylinder is arranged on the connecting seat and has a movable hole penetrating through both ends of the guide cylinder.

The small arm 4024 is fixed with an abutment plate at the end close to the large arm 4022, the third hydraulic cylinder 4023 is abutted with the abutment plate at the end away from the large arm 4022, and through the extension and contraction of the third hydraulic cylinder 4023, the small arm 4024 is pushed to rotate clockwise or is caused to rotate counterclockwise under the action of gravity. The abutment plate can help to smoothly transmit the power of the third hydraulic cylinder 4023 to the small arm 4024.

[0033] Preferably, the small arm 4024 is a telescopic structure, for example, comprising two arm segments telescopically arranged and a driving member, the driving member is drivingly connected with one arm segment, so as to drive one arm segment to telescope relative to the other arm segment, and the driving member can be but is not limited to a driving cylinder. By arranging the telescopic small arm 4024, the insertion or withdrawal of the forklift disc 4025 into or out of the wheel can be directly driven.

[0034] Further, the bottom of the forklift disc 4025 is fixed with a rotating rod, the end of the rotating rod is fixed with a limiting plate, the end of the small arm 4024 away from the large arm 4022 is provided with a rotating hole, the rotating rod is in rotating fit with the rotating hole, and the limiting plate prevents the rotating rod from being separated from the rotating hole. The forklift disc 4025 is hinged with the small arm 4024, so that the broken-down vehicle behind can be driven to turn when the broken-down vehicle turns, and the safety of the broken-down vehicle when being towed is improved.
