Description

Technical Field

[0001] The utility model relates to the technical field of traction structures, in particular to a detachable traction structure. Background Art

[0002] A vehicle is usually provided with a traction member, which can then be used by the vehicle to tow an object to be towed. For example, the traction member on the vehicle can tow another vehicle so that the vehicle in front can drag the vehicle behind to move. However, most traction structures on the market are welded and cannot be disassembled. When faced with high-load operations, the welds are prone to cracking and have a short lifespan. In addition, some traction structures cannot meet the requirements of horizontal and vertical rotation within a certain range and have no multi-directionality. As a result, the towed object cannot follow the movement better during the traction process.

[0003] Based on this, a detachable traction structure is now provided to eliminate the disadvantages of the existing device. Utility Model Content
