[0012] Preferably, the top surface of the base plate has a through-hole, and the through-hole is located between the two first upright plates.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: In use, the operator adjusts the two side rollers and the top roller according to the size of the elevator guide rail. First, the side rollers are adjusted, and the rotating ring is pulled out of the limiting groove and rotated. The rotation of the rotating ring drives the first lead screw to rotate, which in turn drives the first moving block to move, thereby moving the two side rollers to fit against the elevator guide rail. Then, the rotating ring is pushed back into the limiting groove, thus fixing the side rollers against the elevator guide rail. Next, the top roller is adjusted, and the rotating ring is pulled out of the limiting groove and rotated. The rotation of the rotating ring drives the second rod to rotate, which in turn drives the second moving block to move, thereby moving the two top rollers to fit against the elevator guide rail. Then, the rotating ring is pushed back into the limiting groove, thus fixing the top rollers against the elevator guide rail. This completes the installation of the device. The moving block can move on the lead screw, enhancing the applicability of the device. The cooperation between the rotating ring and the limiting groove enhances the stability of the device.

[0021] More specifically, rotating the first lead screw 5 can adjust the distance between the two side rollers and the sides of the elevator guide rail, and rotating the second lead screw 8 can adjust the distance between the top roller and the elevator guide rail, so that it can fit elevator guide rails of different sizes, thereby enhancing the applicability of the device.

[0022] In this utility model, a limiting block 11 is provided at one end of each of the two first lead screws 5 and the second lead screw 8. An installation rod 12 is slidably provided inside the limiting block 11, and a moving rod 13 is slidably provided inside the installation rod 12. One end of the moving rod 13 is connected to one end of the first lead screw 5 and the second lead screw 8, respectively. A limiting groove 14 is provided on one side of the limiting block 11. A rotating ring 15 is connected to the outer wall of the installation rod 12, and the rotating ring 15 is slidably connected to the limiting groove 14.

[0023] More specifically, the movable rod 13 can move within the mounting rod 12, thereby facilitating the adjustment of the top and side rollers 7 by the operator. The limiting groove 14 and the rotating ring 15 are movably connected, enhancing the stability of the device.

[0024] In this utility model, the interiors of the two first mounting slots 4 are respectively provided with first guide rods 16, and the outer walls of the first guide rods 16 are slidably connected to the first moving block 6.

[0025] More specifically, the first guide rod 16 restricts the direction of movement of the first moving block 6.

[0026] In this invention, a second guide rod 17 is provided inside the second mounting groove 19, and the outer wall of the second guide rod 17 is slidably connected to the second moving block 9.

[0027] More specifically, the second guide rod 17 restricts the direction of movement of the second moving block 9.

[0028] In this invention, the other ends of the two first lead screws 5 are rotatably connected to the inner wall of the first mounting groove 4, and the other end of the second lead screw 8 is rotatably connected to the inner wall of the second mounting groove 19.

[0029] More specifically, the first lead screw 5 and the second lead screw 8 are rotatably connected to the inner wall of the mounting groove, thereby facilitating the movement of the first and second moving blocks 9.

[0031] More specifically, the placement port 18 is used for placing elevator guide rails.

[0032] Working principle: During use, the operator adjusts the two side rollers 7 and the top roller according to the dimensions of the elevator guide rail. First, the side rollers 7 are adjusted to pull the rotating ring 15 out of the limiting groove 14 and rotate it. The moving rod 13 can move within the mounting rod 12, thereby moving the rotating ring 15 away from the limiting block 11, facilitating the rotation of the rotating ring 15. The rotation of the rotating ring 15 drives the first lead screw 5 to rotate, which in turn drives the first moving block 6 to move, thereby moving the two side rollers 7. Once the top roller 7 is aligned with the elevator guide rail, push the rotating ring 15 back into the limiting groove 14 to fix it in place. Then, adjust the top roller to pull the rotating ring 15 out of the limiting groove 14 and rotate it. The rotation of the rotating ring 15 drives the second rod to rotate, which in turn drives the second moving block 9 to move. This moves the two top rollers to align with the elevator guide rail. Push the rotating ring 15 back into the limiting groove 14 to fix the top rollers in place. This completes the installation of the device. The moving block can move on the screw, enhancing the device's applicability. The cooperation between the rotating ring 15 and the limiting groove 14 enhances the device's stability.
