The spring 15 is sleeved on the outside of the fixed rod 401, and the far sides of the clamping plate 6 are respectively fixedly connected to the proximal sides of the telescopic rod 402. The top rear end of the mounting plate 2 is fixedly connected with the cross plate 7, and the front end of the cross plate 7 is fixedly connected with the extrusion assembly. The opposite side of the clamping plate 6 is detachably connected with the cylinder body 15, and the rear end of the cylinder body 15 is slidably connected with the piston rod 16, and the rear end of the piston rod 16 is in contact with the extrusion assembly. The extrusion assembly includes multiple springs 801, one end of the multiple springs 801 is fixedly connected to the front end of the cross plate 7, and the other end of the spring 801 is fixedly connected with the movable plate 802.

[0024] A fixing plate 9 is fixedly connected to the left end of the top of the bottom plate 1, and a nitrogen storage tank 10 is fixedly connected to the top of the fixing plate 9. The nitrogen storage tank 10 contains nitrogen. A sealing ring 11 is fixedly connected to the front end of the nitrogen storage tank 10. The sealing ring 11 is set to prevent nitrogen leakage.

[0026] Working principle: when it is necessary to add gas to the nitrogen spring, the nitrogen spring needs to be fixed and limited before that, and the corresponding movement is performed according to the size of the nitrogen spring. The clamping plate 6 moves to both sides under the action, so that the telescopic rod 402 moves in the fixed rod 401, so that the spring 1 5 is squeezed, and the nitrogen spring is limited and fixed between the clamping plates 6 under continuous action. At that time, the injection head 13 is connected to the vent pipe 17. At this time, the valve 18 is opened, so that the nitrogen inside the nitrogen storage tank 10 is injected into the cylinder body 15 through the connecting pipe 12. During the process of injecting nitrogen, the piston rod 16 will continue to move outward due to the internal nitrogen pressure, so that the movable plate 802 starts to move under the action of the piston rod 16, so that the spring 2 801 is squeezed. During the continuous injection process, when the piston rod 16 no longer pushes the movable plate 802 to move, it indicates that the internal nitrogen injection is full. At this time, the valve 18 is closed, and the connecting pipe 12 is taken out to complete the injection of nitrogen spring gas.
