[0028] As Figure 4 , Figure 5As shown, the outer left and right sides of the main shaft 1 are fixedly connected with two first protruding plates 64 distributed on the left and right sides near the upper side, the outer left and right sides of the two protective shells 63 are fixedly connected with second protruding plates 65, the outer sides of the first protruding plates 64 and the second protruding plates 65 are movably sleeved with limiting sleeves 610, and the limiting sleeves 610 are distributed on the left and right sides, the upper sides of the two limiting sleeves 610 and the left and right sides near the bottom are provided with second screw holes 66 extending to the inner side of the first protruding plate 64 in the direction of the main shaft 1.

[0029] It should be noted that the first protruding plate 64 and the second protruding plate 65 are arranged, so that the protective shell 63 can be quickly fixed on the main shaft 1 by means of the limiting sleeve 610, and the second screw hole 66 is used for fixing the limiting sleeve 610 on the first protruding plate 64, which greatly reduces the hole for fixing on the protective shell 63, so that it can be quickly installed.

[0030] As shown in Figure 4 The outer sides of the several protective plates 61 near the horizontal two side edges are fixedly connected with sealing strips 67.

[0031] It should be noted that the sealing strip 67 is used for sealing the gap between the protective plate 61 and the connecting plate 2 to prevent small particles from entering.

[0032] As shown in Figure 4 The outer side of the main shaft 1 is fixedly connected with several vertically distributed sealing rings 68, and the sealing rings 68 are located between the upper and lower adjacent two protective plates 61.

[0033] It should be noted that the sealing ring 68 is used for sealing between the upper and lower adjacent two protective plates 61, and limiting the position of the protective plate 61, facilitating the alignment of the first screw hole 62 to the installation site on the main shaft 1.

[0034] As shown in Figure 4 The side view of the sealing ring 68 is in the shape of an isosceles trapezoid, and the inclined surface faces away from the main shaft 1.

[0035] It should be noted that the shape of the sealing ring 68 avoids relative sliding between the sealing ring 68 and the protective plate 61 when the protective plate 61 is installed, and reduces the degree of wear of the elastic material used for sealing on the sealing ring 68.
