The advantage of this is that the sponge roller 65 rotates against the tooth plate 61, and the excess or accumulated sludge on the tooth plate 61 can be scraped off and cleaned, thereby protecting the guide rail 1.

[0026] The sponge roller 65 can be disassembled and assembled through the fixing part 8. When it is disassembled, the movement of the tooth plate 61 by the mounting frame 2 is not affected. After it is installed, the tooth plate 61 can be cleaned. It can be disassembled and assembled according to actual conditions for easy use.

[0027] In more detail, the sponge roller 65 is fixed to the round rod 64 by a fixing member 8, and the fixing member 8 includes a pair of protrusions 81 provided at the bottom of the round rod 64, and a pair of bending portions 82 are relatively provided at the top of the axial end of the sponge roller 65, and a spring 84 is fixedly connected to the top thereof through a receiving groove 83, and the protrusion 81 can be snapped into the bending portion 82, and the bottom of the round rod 64 can be inserted into the receiving groove 83 and abut against the other end of the spring 84.

[0028] In detail, the round rod 64 is used to resist the spring 84 to provide a downward extrusion force for the sponge roller 65. This extrusion force can make the protrusion 81 tightly clamped in the bending portion 82, so that the sponge roller 65 will not fall due to vibration or accidental operation, and it is also convenient to disassemble and assemble the sponge roller 65.

[0029] In addition, it is necessary to first plug the waste box 73 into the round rod 64, and then install the sponge roller 65 from the inside of the waste box 73 through the fixing member 8, so that the waste box 73 can be fixed by utilizing the effect of the sponge roller 65 resisting the top of the inner wall of the waste box 73.

[0030] In general, the protection component 7 includes an oil tank 71 which is clamped to the top of the inner wall of the mounting frame 2 through a clamping portion, an oil brush 72 is provided in the oil tank 71, the brush end of the oil brush 72 can be tightly pressed against the tooth plate 61, the bottom of the round rod 64 is located above the raised portion 81 and a waste box 73 is inserted therein, the sponge roller 65 is rotatably connected to the waste box 73, and the shaft end at the top thereof can contact the top of the inner wall of the waste box 73.

[0032] The oil tank 71 needs to be installed behind the sponge roller 65 , so that after the tooth plate 61 is cleaned, the oil tank 71 can be oiled by the oil brush 72 , which is beneficial to protecting the guide rail 1 .

[0033] Finally, the waste box 73 and the oil tank 71 are provided with a block 711 and a slot 731 on the side facing each other, and the block 711 is engaged in the slot 731 . An oil scraper 74 is provided in the waste box 73 , and the oil scraper 74 can press against the outer wall of the sponge roller 65 .

[0034] The specific operation is that, because of the rotational connection between the waste box 73 and the round rod 64, in order to prevent the waste box 73 from rotating along with the round rod 64, the waste box 73 needs to be fixed by the action of the clamping block 711 and the clamping slot 731;

[0035] In addition, because the sponge roller 65 rotates to clean the oil stains, the scraper plate 74 can be used to scrape off the sludge accumulated on the periphery of the sponge roller 65 and store the scraped sludge in the waste box 73, so that the sponge roller 65 can better clean the tooth plate 61.
