The utility model further provides that: the limiting piece comprises limiting blocks, limiting grooves are transversely formed in the two side walls of the sliding groove along the length direction of the sliding groove, the limiting blocks are arranged in one-to-one correspondence with the two limiting grooves, and the limiting blocks are arranged in the corresponding limiting grooves in a sliding mode.

The technical scheme is adopted, and the method has the advantages that: the limiting block and the limiting groove are arranged to ensure that the detection plate cannot be separated from the oil cap, and further ensure that the detection plate can smoothly detect the liquid level position of oil in the oil cavity.

The utility model further provides that: the sealing ring is arranged in the detection hole, the sealing ring sleeve is arranged on the matching block, and the outer peripheral wall of the sealing ring is in contact with the inner peripheral wall of the oil drainage hole.

The technical scheme is adopted, and the method has the advantages that: the sealing of the oil drain hole by the oil cap is further improved by the sealing ring, and the phenomenon that the outside of the pump body is polluted due to the fact that oil in the oil cavity leaks is avoided.

The utility model further provides that: arc grooves are formed in the two outer wall surfaces of the matching end of the detection plate.

The technical scheme is adopted, and the method has the advantages that: the setting of circular arc groove makes things convenient for the interior leakage fluid of oil pocket to promote the pick-up plate, and then ensures that the pick-up plate can be smooth detect the interior outer oil drainage fluid level of oil pocket.
