Certainly, in order to make the static guide rail 13 and the movable guide rail 222 normally cooperate with each other, a steel ball loop needs to be formed at the static guide rail 13 or the movable guide rail 222, and in terms of the application, it is more convenient and practical to form a steel ball loop at the movable guide rail 222, as shown in fig. 3, so that the steel ball 6 needs to be guided into or out of the steel ball pipeline 3 by using the steel ball baffle 4, that is, the steel ball 6 on the movable guide rail 222 can be guided into the steel ball pipeline 3 by the steel ball baffle 4, and meanwhile, the steel ball 6 in the steel ball pipeline 3 can also be guided out of the movable guide rail 222; and in order to reduce the whole sliding volume, the steel ball baffle 4 is arranged on the end surface of the support member 22 vertical to the movable guide rail 222.
As shown in fig. 1, the steel ball 6 pipeline 3 is located in the through hole 223, the steel ball 6 pipeline 3 may be integrally connected with the steel ball baffle 4, but for convenience of detachment, the steel ball 6 pipeline 3 may be respectively installed on two steel ball baffles 4, that is, one steel ball 6 pipeline 3 is respectively installed on each of the steel ball baffles 4 at both ends of the slider 2, and when the steel ball 6 pipeline 3 is placed in the through hole 223, the two steel ball 6 pipelines 3 are communicated in the through hole 223, thereby forming a complete steel ball 6 channel; of course, the steel ball 6 pipeline 3 may also be integrally placed in the through hole 223, the two ends of the steel ball 6 pipeline 3 are respectively connected with the steel ball baffle 4, and in order to ensure the detachable effect, the steel ball 6 pipeline 3 needs to be detachably connected with the steel ball baffle 4.
