[0027] The disc 903 is slidably connected to the inner wall of the sleeve 902, and one end of the spring 904 away from the limiting ball 8 is fixedly connected to the inner wall of the sleeve 902, so that the disc 903 slides inside the sleeve 902, plays a role of limiting guide, and is convenient for fixing one end of the spring 904, so as to facilitate the subsequent support and rebound effect of the limiting ball 8;
