[0033] Working principle:

[0034] As Figures 1 to 5As shown, when the screw rod body 2 is replaced, the user rotates the nut 4 counterclockwise by hand, removes the nut 4 from the screw rod body 2, and then manually pulls the screw rod body 2 away from the brake disc body 1, so that the screw rod body 2 and the multi-layer processing mechanism are separated from the outer surface of the brake disc body 1. When the user installs the new screw rod body 2 on the brake disc body 1, the user aligns the insertion block 34 with the insertion slot on the brake disc body 1, inserts the insertion block 34 into the insertion slot on the brake disc body 1, and the arc-shaped block 37 is extruded into the insertion block 34 when the insertion block 34 is inserted into the insertion slot. When the arc-shaped block 37 is extruded into the insertion block 34, the elastic column 36 is pressed, causing the elastic column 36 to deform. When the arc-shaped block 37 moves to the insertion slot inside the insertion block 34, the arc-shaped block 37 is not extruded from the insertion slot. The arc-shaped block 37 is ejected into the insertion slot through the elastic column 36. At this time, the Y-shaped positioning block 35 enters the Y-shaped positioning slot inside the insertion slot. Through the double positioning of the insertion block 34 and the arc-shaped block 37, the screw rod body 2 can be firmly installed on the brake disc body 1. The installation method is simple to operate, shortens the installation time of the screw rod body 2, and improves the installation efficiency of the screw rod body 2. The friction between the screw rod body 2 and the brake disc body 1 is improved by the Y-shaped positioning block 35 during installation, effectively improving the fastening between the insertion block 34 and the brake disc body 1, and improving the quality of the screw rod body 2 installed on the brake disc body 1.

[0035] The external air enters the introduction cavity through the introduction hole on the processing seat 32, and the air enters the processing cavity in the processing plate 33 through the introduction port. Then, part of the air is discharged from the processing hole on the processing plate 33, and another part of the air is introduced into the discharge cavity on the insertion block 34 from the processing cavity, and then discharged from the discharge hole. Through the processing hole on the processing plate 33 and the discharge hole on the Y-shaped positioning block 35, the contact surfaces of the mounting plate 31 and the brake disc body 1 and the contact surfaces of the insertion block 34 and the insertion slot on the brake disc body 1 can be dried simultaneously. Through double drying treatment, rust can be avoided between the mounting plate 31 and the brake disc body 1, so as to prevent rust from entering between the screw rod body 2 and the brake disc body 1, delay the rust generation speed between the brake disc body 1 and the screw rod body 2, and prolong the service life of the screw rod body 2.
