Preferably, a stop block is arranged on the inner side of the lower part of the shaft seat.

The quick release structure of the invention has the following action processes:

when the C-shaped binding ring is required to be fastened, the U-shaped handle is pulled upwards, the pivoting of the U-shaped handle drives the second sliding block clamped on the fixed shaft to rotate together, the second sliding block and the first sliding block which are oppositely arranged rotate at the moment, and due to the arrangement of the slope structure, two high-slope phases mutually approach each other, so that the pair of sliding block components mutually push each other, and a pair of lugs of the C-shaped binding ring are forced to be clamped inwards, so that the function of fastening the C-shaped binding ring is achieved; when the C-shaped binding ring is required to be loosened, the U-shaped handle is pulled downwards in the opposite direction, and at the moment, the slope structure between the sliding block assemblies can be gradually reset to a high-low slope phase matched state, so that the sliding block assemblies are mutually close to each other, a pair of lugs of the C-shaped binding ring are further caused to move outwards, and the effect of loosening the C-shaped binding ring is achieved.

Compared with the prior art, the beneficial effects are that:

1. the quick release structure of the present invention is fastened or loosened by a U-shaped handle, and has a relatively large moment and relatively small force required by an operator.

2. The stress points of the quick-release structure are not handle fulcra in the existing structure, but are transferred to shaft seats on two sides of the U-shaped handle, so that the stress is uniform, and the fastening or loosening of the C-shaped binding ring is realized through the high-low slope dislocation positions of the slope structure between the sliding block assemblies on the two sides, so that the operation hand feeling is further improved, and the fastening or loosening process is smoother.

3. The ball and circular arc groove structures are arranged between the pair of slide block assemblies of the quick-dismantling structure, so that friction between the slide block assemblies is converted into rolling friction between the ball and the circular arc groove, friction loss is greatly reduced, and smooth and comfortable operation is improved.

4. The second circular arc groove on the second sliding block in the sliding block assembly has the function of reducing the weight of the sliding block, thereby reducing the weight of the whole quick-release structure.

5. The stop blocks below the shaft seats on the two sides of the U-shaped handle with the quick-disassembly structure play a role in limiting and protecting, and when the U-shaped handle is pulled up to a vertical position, the stop blocks are blocked on the lugs of the C-shaped binding ring so as to prevent the U-shaped handle from being pulled over the head by improper operation.
