[0006] The riveted special-shaped shift fork push rod structure with assembly limit mainly arranges rivet pads, limit lugs, through holes, the push rod body, connecting blocks and square holes between the push rod body and the special-shaped shift fork. The rivet pads, limit lugs, through holes, the push rod body, connecting blocks and square holes can make the connection more stable and will not fall off. At the same time, it can avoid tilting during assembly, which can reduce processing costs and achieve lightweight design.

[0007] In the above-mentioned riveted special-shaped shift fork push rod structure with assembly limit, an assembly hole is provided on the right side of the top of the special-shaped shift fork, and a sealing cover plate is inserted on the left side of the push rod housing. In practical applications, by providing the sealing cover plate, the interior of the push rod housing can be protected to prevent external oil or impurities from entering the interior and causing pollution.

[0008] In the above-mentioned riveted special-shaped shift fork push rod structure with assembly limit, the sealing cover plate includes a cover plate body, and a rubber block is glued to the right side of the cover plate body. In practical applications, by providing the rubber block, a positioning function can be provided, and its own elasticity can be connected with the push rod housing through interference to fix the cover plate body.

[0009] In the above-mentioned riveted special-shaped shift fork push rod structure with assembly limit, a square hole is opened on the left side of the special-shaped shift fork, the connecting plug is square, and the front and rear sides of the top of the front side of the special-shaped shift fork are opened with folding openings. In practical applications, by providing the folding opening, the limit lug can be easily folded.

[0010] In the above-mentioned riveted special-shaped shift fork push rod structure with assembly limit, a through hole is opened on the left side of the connecting plug block, and the top and bottom of the push rod housing are fixedly connected to the limit push plate. In practical applications, by providing the limit push plate, it is convenient for people to take the shift fork and reduce the risk of losing the hand.

[0011] Compared with the prior art, the advantages of this riveted special-shaped fork push rod structure with assembly limit are: the connection is more stable during the working process and will not fall off; it has a limit function during assembly to avoid tilting, reduces processing costs and achieves the advantages of lightweight design.
