[0024] As an implementation method in this embodiment, Figures 4 - 7As shown in the figure, the webbing cleaning mechanism 2 includes a limiting cylinder member 21. The limiting cylinder member 21 is fixedly installed on the right side of the peripheral kit 1. A plugging foot 22 is movably inserted into the right side of the limiting cylinder member 21. A rubber convex strip 213 is fixedly connected to the outer wall of the plugging foot 22. The outer wall of the rubber convex strip 213 is movably connected to the inner wall of the limiting cylinder member 21. A first magnetic attraction block 211 is fixedly installed on the inner wall of the limiting cylinder member 21 near the left side. A second magnetic attraction block 212 is fixedly installed on the left side of the plugging foot 22. The right side of the first magnetic attraction block 211 is magnetically connected to the left side of the second magnetic attraction block 212. A bent rod 23 is fixedly installed on the right side of the plugging foot 22. A receiving block 24 is fixedly installed at one end of the bent rod 23 away from the plugging foot 22. A cross bar 25 is fixedly installed between the adjacent sides of the two receiving blocks 24. An elastic member 251 is fixedly installed on the side of the cross bar 25. One end of the elastic member 251 away from the cross bar 25 is fixedly installed with a receiving frame body 252. A hollow alloy roller 253 is rotatably connected to the inner wall of the receiving frame body 252. A micro vibration motor 254 is fixedly installed on the left side of the receiving frame body 252. The plugging foot 22 can be inserted into the inner wall of the limiting cylinder member 21. Through the design of the first magnetic attraction block 211 and the second magnetic attraction block 212, the limiting cylinder member 21 and the plugging foot 22 are magnetically connected.
