[0026] The oil inlet joint 23 is of a V-shaped structure.

[0027] As can be seen from the above description, by slidably and sealingly connecting one end of the vertical cylinder 21 to the oil inlet up and down, the oil inlet mechanism 2 can obtain changes in the vertical direction; by rotatably and sealingly connecting the side wall of the horizontal cylinder 22 to the end of the vertical cylinder 21, the horizontal cylinder 22 can rotate within a certain range, and oil circuit interfaces are respectively provided at both ends to achieve bidirectional oil inlet. One of the oil circuit interfaces can be selected for use according to needs. Combined with the V-shaped oil inlet joint 23, multi-directional oil inlet can be realized, greatly improving the flexibility and versatility of the oil circuit layout.

[0028] Further, the oil inlet joint 23 is of an obtuse V-shaped structure.

[0029] As can be seen from the above description, through the obtuse V-shaped structure, the oil inlet joint 23 can be prevented from bending towards the carburetor body 1.

[0030] Further, the plug 24 is made of a transparent material.

[0031] As can be seen from the above description, through the transparent plug 24, it is possible to directly observe whether the oil circuit is smooth through the plug 24 without adding an observation window, improving the installation efficiency.

[0032] Further, the plug 24 is arranged in the horizontal channel.

[0038] Further, one end of the vertical cylinder 21 is slidably and sealingly connected up and down inside the oil inlet.

[0039] As can be seen from the above description, by arranging the vertical cylinder 21 inside the oil inlet, the vertical cylinder 21 can be protected by using the structure of the main body 1 corresponding to the oil inlet, ensuring the service life of the vertical cylinder 21.

[0040] Further, the main body 1 corresponding to the oil inlet is provided with a protective cover 11 extending towards the vertical cylinder 21.

[0041] As can be seen from the above description, through the arrangement of the protective cover 11, the impact of foreign objects can be reduced, and thus the force received by the vertical cylinder 21 in the horizontal direction can be reduced.

[0042] Further, an outwardly protruding ring 231 is provided on the free end of the oil inlet joint 23.

[0043] As can be seen from the above description, through the ring 231, an annular contact surface can be formed when cooperating with the flexible oil delivery pipeline.
