Description

Technical field:

[0002] The utility model relates to an adjustable lifting towing head structure for towing a vehicle body. Background technology:

[0004] At present, a two-wheeled vehicle body is provided with a tow bar at the front end for towing the vehicle body. When not towing, the front end of the tow bar needs to be supported on the ground by a vertical support bar. The height of the vertical support bar is currently fixed. When the towing hook of the towing vehicle is too high or too low, the trailer and the towing vehicle are likely to be mismatched, which can easily cause the trailer platform to tilt, thereby affecting the normal operation of the equipment on the trailer or causing sudden situations such as the falling of the cargo on the trailer. The above situation is also likely to occur when the supporting ground is a slope.

[0005] For example, the Chinese patent "Drum-type LED Lighting Vehicle", publication number CN214647877U, includes a support frame, a pair of rotatable moving wheels are provided at the lower part of the support frame, a generator cover that can be placed in the generator is fixed on the upper part of the moving wheels, a support rod is provided on the side of the generator cover, an LED lighting lamp is fixed on the top of the support frame, and the LED lighting lamp includes an outer cylinder and an inner cylinder located in the outer cylinder, an LED light board is fixed on the surface of the outer cylinder, and the LED light board is evenly distributed on the outer surface of the outer cylinder along the vertical direction, and the bottom of the outer cylinder and An annular bottom plate is fixed between the bottoms of the inner cylinders, and a power supply is fixed in the inner cylinder. The power supply is connected to the LED light board through a wire running through the inner cylinder and the outer cylinder. Although the patent structure is compact and can be easily moved and arranged to meet the circumferential lighting needs of outdoor space, it can adapt to various working environments; but the height of the tow bar is fixed. When the towing hook height of the towing vehicle is too high or too low, the trailer and the towing vehicle are prone to mismatch, which can easily cause the trailer platform to tilt, thereby affecting the normal operation of the equipment on the trailer or sudden situations such as the falling of goods on the trailer. Summary of the invention:
