When the exhaust lever 40 rotates, the ejector part 43 can extend into the lower part of the pressure limiting valve 20 to jack up or lower the pressure limiting valve 20. Specifically, in the direction approaching the lever portion 41, the distance between the driving inclined surface portion 513 and the axis of the push rod 512 is gradually reduced, and during the movement of the driving slider 51 in the linear direction, the driving inclined surface portion 513 can extend to the lower side of the lower surface of the portion, located between the rotating shaft portion 42 and the pushing top portion 43, of the lever portion 41 to push against the lever portion 41, so that the exhaust lever 40 rotates, the pushing top portion 43 is lifted up or dropped down, and the pushing top portion 43 pushes up or drops down the pressure limiting valve 20.

As shown in fig. 4, 8, 10 and 11, in the present embodiment, the driving slope part 513 is a curved surface, so that when the lever part 41 is pushed, the contact area between the driving slope part 513 and the lever part 41 is small, which can reduce wear. The end of the driving ramp portion 513 remote from the second projection 511 is provided with a protrusion 514, and the protrusion 514 is provided below the portion of the lever portion 41 between the rotating-shaft portion 42 and the ejector portion 43.
