The guide plate 57 on the second horizontal partition 56 is inserted into the inverted U-shaped limit piece 31. When the vertical protective cover 3 moves horizontally, the guide plate 57 cooperates with the inverted U-shaped limit piece 31 to ensure that the vertical protective cover 3 moves in a straight line.

[0031] A force-bearing member 61 is provided in the transmission cavity 52 below the second horizontal partition 56. One end of the force-bearing member 61 is provided with a hemispherical surface 64 and can pass through the second horizontal partition 56 and is located in the limiting cavity 51. The other end of the force-bearing member 61 passes through the collecting cavity 53 and extends to the outside of the lower guide rail profile 5 and is connected to the vibration collecting plate 63. A spring 62 is provided below the force-bearing member 61.

The diameter of the first bearing 24 is smaller than the diameter of the roller 23. The surface of the outer ring 241 of the first bearing 24 is engraved with threads. The threaded hole on the upper part of the vertical protective cover 3 is fixed to the outer ring 241 of the first bearing 24 by screwing. The inner ring of the first bearing 24 rotates synchronously with the rotating shaft 22, and the outer ring of the first bearing 24 does not rotate due to the action of the bearing ball; the vertical protective cover 3 passes through the first horizontal partition 14 between the roller moving cavity 11 and the counterweight cavity 12, and then passes through the bottom plate of the counterweight cavity 12 to extend to the lower guide rail profile 5.

[0037] like Figure 3 As shown, when the horizontally movable inverted U-shaped stopper 31 does not contact the hemispherical surface 64, the force-bearing member 61 is not subjected to the force and the spring is not squeezed.

[0038] like Figure 4 As shown, when the first rounded corner 311 of the horizontally movable inverted U-shaped stopper 31 contacts the hemispherical surface 64, the force-bearing member 61 is pressed downward, the spring 62 is compressed and deformed, and the vibration collecting plate 63 also moves downward.

[0039] When the horizontally movable inverted U-shaped limit piece 31 separates from the hemispherical surface 64 of the force-bearing piece 61, the spring 62 releases the elastic force to push the force-bearing piece 61 upward, and the force-bearing piece 61 and the vibration collecting plate 63 will vibrate under the action of the spring released elastic force, and the waste chips attached to the vibration collecting plate 63 will leave the vibration collecting plate 63 and enter the collection chamber 53 under the action of gravity.
