Abstract
A cylinder includes a cylinder body assembly, a cylinder rod assembly, and a piston assembly. The cylinder body assembly includes a cylinder body. The cylinder body defines a receiving chamber. The cylinder rod assembly includes a rod fixed with the cylinder body. The rod includes an inclined resisting surface. The piston assembly includes a piston, a piston rod, and one or more resisting member. The piston is slidably received in the receiving chamber and sleeved on the rod. The piston rod protrudes from the piston and extending out from the receiving chamber. The piston rod is sleeved on the rod, and defines a through hole. The resisting member is movably mounted in the through hole. The piston and the piston rod slide relative to the rod, which enable the resisting surface to resist the resisting member to be partially exposed from the through hole.
