[0051] Further, in the rotating clamping process, the clamping protrusion can move along the guide slope 212 towards the clamping groove, thereby ensuring the clamping accuracy, and the opening width of the open end 211 at the guide slope 212 is gradually reduced towards the clamping groove, so that the clamping protrusion can be gradually clamped in the clamping groove during the rotating process, and a damping feeling can be generated during the rotating clamping process, thereby improving the user experience, and the clamping protrusion is clamped in the clamping groove, which can avoid shaking and other situations during use, and ensure the clamping reliability.
