Lockable gas spring can lock anywhere during the stroke. Press the lift rod at the top of piston rod to open the internal valve and get inert gases or fuel-air mixture running so that the lockable gas spring can stretch freely like compressed gas spring; then release the lift rod to close the valve and lock the piston rod at the required position. Lockable gas spring can carry a relatively large load and would lose its locking function should the load be too much.
Lockable gas spring plays the role of the support, adjusting height or angles. It can stop over anywhere via adjusting the handle with easy, smooth operation and comfortable use.
