Furthermore, a pin shaft penetrates through the upper portion of the linkage sleeve, openings for allowing the pin shaft to be inserted and move up and down are formed in two sides of the linkage sleeve, a push rod abutting against the upper end of the linkage sleeve penetrates through the vertical through hole in a movable mode, and a first spring is arranged between the second groove and the valve rod.

Furthermore, a sleeve penetrates through one side of the valve body, a limiting pin transversely penetrates through the sleeve, a spring seat is arranged on the limiting pin, and a second spring for promoting the limiting pin to move towards the valve rod is arranged between the spring seat and the sleeve.

Furthermore, an annular groove which can be inserted by a limit pin and can move is formed in the linkage sleeve, and when the linkage sleeve moves downwards to enable the internal spline and the external spline to be connected, the limit pin is inserted into the annular groove.

Furthermore, the lower end of the vertical through hole is provided with an annular step, and the push rod is provided with an annular clamping block capable of being abutted to the annular step.

After the technical scheme is adopted, when the exhaust valve needs to be opened and closed, the push rod is pressed down first, the push rod drives the linkage sleeve to move downwards, the inner spline of the second groove is connected with the outer spline of the valve rod, then the rotating wheel switch is rotated to drive the linkage shaft, the pin shaft, the linkage sleeve and the valve rod to rotate, and therefore the purpose of opening and closing the exhaust valve is achieved.
