The second ramp inclination angle was found to be 30 degrees from the top end face of the upper stop and to be 60 degrees from the first ramp inclination surface to work best in the design. In the design, the curvature of 1/3 section of the blocking spring close to the driving sharp corner in the blocking spring in the free state is 0 in the natural telescopic state, so that the design ensures that the space between the driving sharp corner and the second inclined block is blocked by the blocking spring; since the curvature is 0 so that the top surface of the retaining spring is close to a plane and parallel to the top surface of the second sloping block, the easy-to-wind object is prevented from being wound in the gap between the second sloping block and the driving sharp corner. When the driving sharp corner is clamped into the crawler, the crawler applies pressure to the blocking spring, and one end of the blocking spring slides into the blocking spring groove through deformation, so that interference with the crawler is avoided, and transmission is not influenced; when the pressure disappears, the stop spring restores to the original state under the elastic force.
