As a further scheme, an annular pressing groove is formed in the edge, corresponding to the leather cup, of the top surface of the rod head, and the leather cup is tightly pressed on the annular pressing groove. The leather cup is a rubber part, and is in concave-convex fit with the annular pressure groove after being pressed and deformed, so that the leather cup plays a role in positioning and is prevented from loosening.
As a further scheme, a reinforcing rib is arranged between the club body and the club head, and the cross section of the club body is I-shaped.
The utility model has the advantages as follows:
(1) the air inlet valve is additionally arranged on the rod head of the compressor connecting rod with the air inlet valve, so that air can be fed from the shell when the compressor works, the heat dissipation effect of the shell is achieved, the gas temperature is ensured not to be too high, and the temperature rise of a product is effectively reduced.
(2) The rod head of the compressor connecting rod with the air inlet valve is provided with the annular pressing groove, the leather cup is prevented from loosening, and the leather cup and the two ends of the pressing plate are fixed through the pressing plate fixing screws, so that the compressor connecting rod is convenient to install.
