A limiting plate 11 is provided on the outer wall of the connecting rod 9, and a tension spring 10 is fixedly connected to the rear side of the limiting plate 11 relative to one end, and a through hole 12 is provided on the front side of the limiting plate 11 relative to one end, and a fixing rod 4 is provided on the inner wall of the through hole 12, and the tension spring 10 is fixedly connected to the second sealing block 5 at the opposite end at the left and right ends corresponding to the outer side of the connecting rod 9, and the shape of the fixing rod 4 matches the through hole 12.

[0025] Specifically, the cleaning ring 7 is inserted into the mounting grooves 6 of the second sealing block 5 and the first sealing block 2, the second sealing block 5 is first placed on the gas spring body 1, the clamping rod 3 on the first sealing block 2 is inserted into the clamping groove 8, and then the limiting plate 11 is pulled, the through hole 12 on the limiting plate 11 is inserted into the fixing rod 4, and the first sealing block 2 is limited by the tension spring 10. When the gas spring body 1 is in use, the cleaning ring 7 can clean the corresponding dust and impurities attached to the piston rod. At the same time, the first sealing block 2 and the second sealing block 5 can prevent dust from affecting the use of the piston rod and affecting the purity of the oil-gas mixture, thereby preventing the piston rod from being unable to support.

[0026] The four sides of the top of the fixed plate 13 are rotatably connected to the rotating rod 14, the top of the rotating rod 14 is rotatably connected to the slider 15, the outward end of the slider 15 is fixedly connected to the first spring 17) The outward end of the first spring 17 is fixedly connected to the load-bearing plate 16, the outer wall of the slider 15 is slidably connected to the four sides of the inner wall of the load-bearing plate 16, the rear side of the inner wall of the first sealing block 2 is arranged on the front side of the outer wall of the gas spring body 1, and the shape of the clamping rod 3 matches the clamping groove 8.

[0027] Specifically, when the gas spring body 1 is in use, when the upper load-bearing plate 16 is forced to move downward, the slider 15 will slide outward, driving the rotating rod 14 to rotate, and applying the upward force of the load-bearing plate 16 to the gas spring body 1, thereby increasing the force-bearing area of ​​the gas spring body 1, and the gas spring body 1 can more evenly withstand the external pressure or load.
