[0025] A hemispherical annular groove identical to the surface of the ball 5 is provided at the center of the upper cover plate 601, and connecting ropes 7 are fixedly connected to the two side surfaces of the upper cover plate 601. The diameter of the groove on the lower surface of the upper cover plate 601 is the largest and is the same as the diameter of the ball 5. A countersunk hole is provided on the upper cover plate 601, and a hemispherical annular groove opposite to the upper cover plate 601 is provided at the center of the lower cover plate 602. A countersunk hole corresponding to the upper cover plate 601 is provided on the lower surface of the lower cover plate 602.

[0026] The limiting mechanism 4 includes a pulling frame 401, a sliding shaft 402, a spring 403, a slide plate 404, and a sliding plate 405.

The noise it emits is much lower than the sound of the balls 5 colliding with each other, achieving a low noise effect. The rubber block 3 will block out external dust and impurities on the guide rail, avoiding the slider from moving unsteadily. After the rubber block 3 has been used for a period of time, the contact surface between the rubber block 3 and the guide rail will wear out.

At this time, the rubber block 3 is not restricted and can be directly taken out from the groove of the dust cover 2. Then, a new rubber block 3 is placed in and the pulling frame 401 is released. At this time, the spring 403 will use its own elastic force to push the sliding plate 405 back to its original position to restrict the rubber block 3 again.
