[0022] The connecting mechanism 2 comprises a T-shaped connecting pipe 21, a rotating ring 23, an inclined table 25 and a clamping column 26. The inner part of the left oil outlet pipe 4 is inserted with the T-shaped connecting pipe 21 (a plurality of T-shaped connecting pipes 21 can be arranged and connected to any oil outlet pipe 4 or oil inlet pipe 3, and then the stability and sealing of the T-shaped connecting pipe 21 and the corresponding oil outlet pipe 4 or oil inlet pipe 3 are ensured by welding).
