[0002] The power supply vehicle uses an engine with non-electric start and air as the cooling medium, which not only eliminates the trouble of battery and bellows water tank maintenance and refilling coolant, but also can work in harsh environments such as extremely high and low temperatures and dust. Due to the special nature of the power supply vehicle, emergency rescue and other work are required, and the materials carried must be sufficient. The common carriage structure may not be able to accommodate enough. At this time, a trailer is needed to increase the delivery of materials, etc., and the common towing device uses a tow hook to achieve this.

[0003] Referring to the Chinese authorized patent with authorization announcement number: CN220114405U: vehicle towing device, the utility model has the beneficial effects of simple structure, easy disassembly and assembly, low manufacturing cost, etc.

[0004] The above patent allows the trailer device to be disassembled conveniently when not in use, but it needs to be reinstalled when in use, which is time-consuming and laborious. At the same time, when the trailer device is not in use and has not been disassembled, the tow hook is exposed. When a vehicle rear-ends the rear vehicle, it may cause serious damage to the rear vehicle or even a more serious traffic accident. Utility Model Content

[0011] In a further embodiment, a limiting block is fixed to one end of the towing hook, and a limiting ring for limiting the position of the fixing sleeve is fixed to the outer wall of the positioning sleeve.

[0012] Technical effects and advantages of the utility model:

[0013] The power vehicle towing device has a movable towing hook. When the towing hook is not used, the towing hook can be turned over and pushed toward the mounting bracket to store the towing hook, thereby preventing the towing hook from extending outside the vehicle body. When the rear vehicle rear-ends, the rear vehicle can be prevented from being seriously damaged due to the exposed towing hook.

[0014] By rotating the adjusting screw, the support block and the push block are driven to move, so that the push block is separated from the fixing pin, and the fixing spring pushes the fixing ring and the fixing pin to move, so that the fixing pin is recovered into the positioning sleeve, and the fixing sleeve and the towing hook can be quickly disassembled. The towing device for the power vehicle can not only quickly disassemble and assemble the fixing sleeve, but also store the towing hook when not in use, which saves more space and is also safer.
