[0007] Preferably, an inlet and outlet hole is opened at the upper end of the mechanism housing, and the telescopic push rod extends out of the mechanism housing through the inlet and outlet hole, and the telescopic push rod can drive the cleaning scraper to move.

[0008] Preferably, the telescopic push rod is movably installed in the mechanism housing through a movable slider, and the cleaning scraper is movably installed in the protective cover through the telescopic push rod. One end of the first spring is connected to the bottom of the mechanism housing, and the other end of the first spring is connected to the movable slider. The second spring can provide elastic force for the telescopic push rod so that the telescopic push rod has a tendency to move forward.

[0009] Preferably, a limit slot is provided on the release rod, and the limit pin is embedded in the release rod through the limit slot, and the limit pin can be stuck in the limit slot.

[0010] Preferably, a movable groove is provided in the limit seat, and the limit pin is movably installed in the limit seat through the movable groove. One end of the second spring is connected to the limit pin, and the other end of the second spring is connected to the upper end of the movable groove.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. In this application, a first spring pushes the telescopic push rod forward, which in turn drives the cleaning blade forward, causing it to contact the dirt on the inner wall of the protective cover. The trenching disc then drives the cleaning blade to rotate, thereby quickly cleaning the dirt on the inner wall of the protective cover.

[0014] 2. In this application, as the ditching disc accelerates, the centrifugal force acting on the stop pin increases. This increases the centrifugal force, causing the stop pin to disengage from the stop slot. Once the stop pin is released from the stop slot, the release lever releases, facilitating the ejection of the cleaning blade. When the stop screw is tightened, its tip presses against the stop pin, securing the cleaning blade and preventing it from ejecting. BRIEF DESCRIPTION OF THE DRAWINGS
