There is a one-way valve 2 5, with a valve port 2 501 at the front end of the one-way valve 2 5 and an oil inlet 505 on the right side of the one-way valve 2 5. An installation platform 2 502 is set inside the one-way valve 2 502, and a telescopic rod 2 503 is installed inside the installation platform 2 502. A baffle 2 504 is fixedly installed on the top of the telescopic rod 2 503. An oil outlet 2 305 is set on the outside of the installation groove 2 304. An oil outlet 1 202 is set on the top of the guide 2. A one-way valve 1 4 is fixedly installed inside the oil outlet 1 202. A valve port 1 401 is set in the middle of the top of the one-way valve 1 4. A sealing plate 402 is set at the bottom of the valve port 1 401. A connecting rod 403 is set at the bottom of the valve port 1 401. A base plate 404 is fixedly installed at the bottom of the connecting rod 403.
