One end of the oil inlet pipe 6 and the oil outlet pipe 7 is fixedly connected to and communicates with the cylinder body 1, and the other end extends to the rear end of the cylinder body 1 and is installed with a valve body 8.

[0030] In one embodiment, Figures 1 to 3As shown, one end of the piston rod 3 is sleeved in the piston 2 and the end is fixedly mounted on the piston 2 via a piston nut 9;

[0031] The piston nut 9 is fixedly connected to the end of the piston rod 3 via a set screw 10 and a steel ball 11 .

[0032] In one embodiment, Figures 1 to 3 As shown, an OO ring 12 is provided between the piston rod 3 and the piston 2 .

[0033] In one embodiment, Figures 1 to 3 As shown, a support ring 13 and a sealing ring 14 are provided between the piston 2 and the cylinder body 1 .

[0034] In one embodiment, Figures 1 to 3 As shown, a OO ring 12 and a dumbbell ring 15 are provided between the front cover 4 and the cylinder body 1 .

[0038] Working principle: When the utility model is working, it is first connected to the supporting equipment through the lifting ring 5, and the connecting ring 18 is connected to the fixed position. When working, the hydraulic oil enters the cylinder body 1 through the valve and the oil inlet pipe 6, thereby pushing the piston 2 to move, thereby driving the piston rod 3 to move in the cylinder body 1, thereby driving the supporting equipment to move, helping the machine to be supported on the ground. Conversely, when contraction is required, the hydraulic oil will flow into the oil tank from the oil outlet pipe 7 and the valve body 8. At this time, the pressure in the cylinder body 1 becomes smaller, and the piston 2 drives the piston rod 3 to retreat, thereby completing the work.

[0039] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
