Description

Technical Field

A mounting groove 011 is coaxially provided on one side of the shell 01. A mounting port 012 is coaxially provided at the bottom of the mounting groove 011. The cylinder 02 is coaxially fixedly connected to the inner wall of the mounting port 012. The shell 01 and the cylinder 02 are integrally formed. Both ends of the cylinder sleeve 03 are sealed with the cylinder 02 through a sealing structure. A through-hole 031 is provided on the inner wall of the cylinder sleeve 03. A through-hole 021 is provided on the outer wall of the cylinder 02. There are four through-holes 021. The four through-holes 021 are evenly spaced around the axis of the cylinder 02. The through-hole 031 and the through-hole 021 are both provided in the mounting groove 011. The through-hole 031 and the through-hole 021 are both provided between the two sealing structures. The through-hole 021 is connected to the through-hole 031.
