In an alternative embodiment, the damping structure 25 includes a friction surface provided on at least one of the adjusting portion 21 and the casing 10. The friction surface has a large friction coefficient, and when the adjustment portion 21 rotates relative to the housing 10, the friction surface can increase the resistance force applied when the adjustment portion 21 rotates, thereby improving the stability of the locking member 30. For example, the adjustment portion 21 may be provided with a friction surface having a large friction coefficient, such as a friction pattern or an undulating pattern, on the surface of the projecting side of the arm 22. Or the surface of the casing 10 is provided with a friction surface with large friction coefficient, such as a grinding pattern, an undulating pattern and the like, and the arc-shaped hole 11 is positioned in the friction surface range.
