[0024] A mounting plate 15 is disposed at one end of the slide plate 14 , and a brush 16 is disposed on one side of the mounting plate 15 .

[0025] The outer rings of the shaft 10 on both sides of the middle part are provided with threads, the outer ring of the shaft 10 is connected to the first fastening nut 4 through threads, and the outer ring of the screw rod 12 is connected to the second fastening nut 13

[0026] In this embodiment, when in use, firstly, the connection between the mounting block 1 and the support rod 2 is locked by bolts, and then one end of the shaft rod 10 is passed through the inner cavity of the rotating groove 3, and the guide wheel 6 is rotatably connected to the outer ring of the shaft rod 10 through the bearing. The bearing can reduce the friction when the guide wheel 6 rotates, so that the rotation of the guide wheel 6 is smoother, and then the connection between the guide wheel 6 and the support rod 2 is locked by the first fastening nut 4. At this time, the collar 9 is sleeved on the outer ring of the shaft rod 10, and the connection between the two fixing blocks 11 is locked by the second fastening nut 13. The overall assembly and disassembly is convenient and quick, which improves practicality.

[0027] Depend on Figure 2 As shown, the baffle 7 surrounds the outer ring of the guide wheel 6, which can protect the guide wheel 6 and prevent impurities from falling on the top of the guide wheel 6; the brush 16 can clean the surface of the guide rail when the elevator starts, and the dust brushed off can slide down along the slide plate 14 to prevent impurities from getting stuck between the guide wheel 6 and the guide rail, thereby ensuring that the guide wheel 6 can rotate stably and reducing the wear of the guide wheel 6 during use.

[0028] The outer ring sleeve of the shaft rod 10 is provided with a gasket 5 , and the gasket 5 is located on one side of the first fastening nut 4 .

[0029] In this embodiment, the gasket 5 can prevent the connection between the first fastening nut 4 and the shaft 10 from loosening, so as to improve the stability of the device. The gasket 5 is a prior art and will not be described in detail here.

[0030] Among them, a limit plate 17 and a fixed plate 18 are respectively provided on one side of the bracket 8, the limit plate 17 is located above the support rod 2, the fixed plate 18 is located on the side of the support rod 2, and a plurality of connecting blocks 19 are fixedly connected to the bottom of the fixed plate 18, a rotating rod 20 is connected between the two connecting blocks 19, the outer ring sleeve of the rotating rod 20 is provided with a clamping plate 21, and the side wall of the support rod 2 is rotatably connected to a plurality of guide plates 24.
