When the upper protective cover 2 and the lower protective cover 3 are oppositely fitted, the adjusting screw 41 rotates to move the movable plate 42 and embed the limit head 421 into the corresponding fixed cylinder 341, so that the upper protective cover 2 and the lower protective cover 3 remain in a stable state. The connection method between the upper protective cover 2 and the lower protective cover 3 is simple, and the upper protective cover 2 and the lower protective cover 3 are easy to disassemble and assemble. The inner wall of the lower protective cover 3 is provided with a limiting rod 32 passing through the end of the movable plate 42. The limiting rod 32 serves to limit the movable plate 42 to prevent the movable plate 42 from tilting.

[0028] In this embodiment, the lower protective cover 3 is a rectangular box structure with one side open, and the opposing limiting semi-rings 33 form a circular ring. A pipe hole identical to the circular ring is provided at the bottom center of the lower protective cover 3, and the oil pump pipeline 11 or the connecting pipeline 12 passes through the pipe hole.
