Specifically, the wire 40 is accommodated in the hydraulic chamber 11, and the first limiting portion 13 is provided with a wire passing hole 131, and along the floating direction of the floating member 30, the bottom end of the wire 40 is connected with the top end of the floating member 30, and the top end of the wire 40 passes through the wire passing hole 131 to be connected with an external control mechanism.
With continued reference to fig. 1 and with further reference to fig. 4, the wire 40 includes a telescopic portion 41 and a penetrating portion 42, wherein two ends of the telescopic portion 41 are respectively connected with the top end of the body 31 and the bottom end of the penetrating portion 42 along the floating direction of the floating member 30, and the top end of the penetrating portion 42 is penetrated through the wire through hole 131 and connected with an external control mechanism.
