[0023] By installing the connecting groove, the connecting groove can guide and limit the adjusting assembly composed of the connecting ring and the adjusting ring, so that the adjusting assembly and the limiting rod are more stably adjusted.

[0024] In summary, the utility model has the following beneficial effects:

[0025] 1. By setting a locking rod and a positioning head, the locking rod adjusts its position as the reinforcing ring is installed, which drives the positioning head to move and make the locking head contact the groove and position itself inside. This locking structure allows the wheel-side half-shaft body to be locked conveniently and stably. Secondly, when the wheel-side half-shaft body needs to be disassembled for maintenance, it is also convenient to adjust the locking rod to release the lock, which improves the practicality of the wheel-side half-shaft locking structure.

[0026] 2. By setting locking rods, the symmetrically distributed locking rods penetrate and engage with the inner end of the clamp head, which can prevent the clamp head from shifting during locking, making the locking between the structures more stable;

[0027] 3. By setting a limiting rod and an adjusting component, the adjusting component can be adjusted in position with the limiting rod to reach the outer end of the connector and restrict the connector, thereby making the connector and locking rod lock the clip more stably and preventing it from falling off.
