The spherical structures at the two ends of the ball stud 7 enable the two ends of the ball stud to be connected with the cam 2 and the locking energy-absorbing releasing mechanism in an abutting mode and can be twisted at the same time, so that the ball stud cannot be separated from the cam 2 and the locking energy-absorbing releasing mechanism when the axial length of the ball stud is rapidly adjusted to achieve the locking/unlocking function, the collision between the cam 2 and the locking energy-absorbing releasing mechanism in an unlocking state is avoided, unnecessary abrasion is reduced, and the use noise is effectively reduced. In other possible embodiments, the spacing adjustment mechanism may be a connector of other structure that changes the axial length by twisting.
Furthermore, two limiting pits 301 matched with the end parts of the ball stud 7 are arranged on the outer end face of the locking energy-absorbing release mechanism, and the ball stud 7 is arranged in the limiting pits 301 and can rotate relative to the limiting pits 301.
