[0034] The rotating ring 401 is rotatably mounted on the outer wall of the oil inlet pipe 2, and the rotating ring 401 is used to synchronously drive the stop block 404 to move;

[0035] The transmission rod 402 is eccentrically connected to the outer wall of the rotating ring 401, and the transmission rod 402 is used to synchronously drive the two rotating rings 401 to rotate;

[0036] The positioning rod 403 is fixed to the end of the connecting pipe 3, and the positioning rod 403 is used to provide a limit for the connection between the oil inlet pipe 2 and the connecting pipe 3;
