[0022] During use, first adjust the distance between the first slider 1 and the second slider 2, and use the provided positioning rod 11 for positioning. Then, horizontally push the adjustment block 16 to adjust the position of the auxiliary roller 18, facilitating the subsequent sliding of the entire guide slider along the guide rail;

[0023] As a further implementation manner of this embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, on one side of the first slider 1, there is a second slider 2 distributed. An activity groove 3 is opened on the side wall of the first slider 1, and on one side of the activity groove 3, there is a slot 4 distributed. The bottom of the slot 4 is communicated with a positioning hole 5. The positioning holes 5 are equidistantly distributed at the bottom of the slot 4, and the slot 4 and the first slider 1 form an integrated structure. On the side of the second slider 2 close to the first slider 1, a stretching rod 6 is fixedly installed, and at the other end of the stretching rod 6, a limiting slider 7 is fixedly connected. A first spring 8 is sleeved on the outer surface of the stretching rod 6. On one side of the stretching rod 6, there is a plug board 9 distributed. And at the inner side of the bottom of the plug board 9, a second spring 10 is fixedly connected. The other end of the second spring 10 is fixedly connected with a positioning rod 11. The positioning rod 11 forms a sliding connection with the plug board 9 through the second spring 10, and the outer diameter dimension of the positioning rod 11 is adapted to the inner diameter dimension of the positioning hole 5. On the lower surface of the top end of the second slider 2, there is a cushion block 12. A groove 13 is opened on the inner side wall of the bottom of the second slider 2, and on one side of the groove 13, there is a through hole 14 communicated. On the surface of one end of the bottom of the second slider 2, there is a clamping groove 15. The groove 13, the through hole 14 and the clamping groove 15 form an adapted structure, and the adapted structure is arranged on the inner side wall of the bottom of the second slider 2.
