[0031] When the cylinder 112 is disassembled by using the utility model, the two handles 120 are pulled from opposite directions, so that one of the handles 120 pulls the connecting plate 115, and the other handle 120 pulls the I-shaped block 110, and the linkage plate drives the fixing rod 113 to move out of the through hole 118, and then the I-shaped block 110 is moved downward, so that the disassembly of the cylinder 112 can be completed. When it is necessary to install, the two handles 120 are continued to be pulled from opposite directions, and the I-shaped block 110 is placed in the adjusting groove 109 and adjusted to a suitable height, and then the two handles 120 are loosened, and the connecting plate 115 is acted upon by the spring 117, and the two fixing rods 113 are inserted into the through hole 118 and penetrate the I-shaped block 110, so as to complete the installation of the cylinder 112.
