The typically small size of miniature springs allows them to provide stable pressure and a large amount of deformation within a limited space. This size characteristic makes miniature springs ideal for the compact designs of miniature devices and precision instruments.

[0003] The specification of a low-friction lockable gas spring in the prior art (publication number CN210196339U) mentions that "the telescopic assembly includes a cylinder, a piston, a piston rod, a bushing spacer, a spacer, a first sealing ring, and a gas chamber. The gas chamber is opened in the inner cavity of the cylinder. The piston rod is fixedly connected to the piston. The bushing spacer is fixedly connected to the cylinder. The spacer and the bushing spacer are integrally formed. The spacer is fixedly connected to the cylinder. The first sealing ring is fixedly connected to the bushing spacer and is located on the side of the bushing spacer near the periphery of the gas chamber. The piston rod is slidably connected to the bushing spacer and the spacer and extends through the bushing spacer and the spacer to the left end of the cylinder." However, the springs in the prior art are prone to wear and slippage during use, and are not strong and durable. Utility Model Content

A reinforcing core is provided in the center of the spring, and an upper fixing sleeve is fitted on the upper part of the spring, and a lower fixing sleeve is fitted on the lower part of the spring. The upper fixing sleeve and the lower fixing sleeve are symmetrical about the center line of the spring, and the upper fixing sleeve and the lower fixing sleeve have the same structural configuration.

[0006] Preferably, the thickness of the middle leather sleeve is half the thickness of the side leather sleeve, and both the middle leather sleeve and the side leather sleeve are made of silicone rubber.
