[0032] A partition 404 is embedded in one side of the one-way liquid outlet valve 403 and on the inner wall of the connecting groove 402. A derivation pipe 405 is embedded in one side of the partition 404 and on the inner wall of the connecting groove 402. One end of the derivation pipe 405 extends to the outer wall of the shell 401. One end of the derivation pipe 405 is installed with a liquid oil pump 407 through the electric control valve 406. When the switch of the controller 9 is turned on, the controller 9 controls the liquid oil pump 407 to operate, so that the liquid oil pump 407 extracts the hydraulic oil flowing out of the one-way liquid outlet valve 403 through the derivation pipe 405.
