Further, a piston 209 is connected to one end of the rod 202 located inside the fixed cylinder 201, and the piston 209 slides inside the fixed cylinder 201, so that the gas volume between the piston 209 and the fixed cylinder 201 changes. Install third spring 210 between piston 204 and the solid fixed cylinder 201 bottom, the elasticity of third spring 210 makes piston 209 remove to the direction of keeping away from solid fixed cylinder 201 bottom, it is provided with air vent 209a and check valve to run through on the piston 209, the check valve is commonly used check valve, make the gas in the solid fixed cylinder 201 can pass through the check valve and discharge solid fixed cylinder 201 during its effect, and outside gas can not enter into solid fixed cylinder 201 through the check valve in, the check valve is prior art, do not give unnecessary details.
The principle of the embodiment is as follows: in the initial state, the third spring 210 is compressed to the shortest, the gas capacity between the piston 209 and the fixed cylinder 201 is the smallest, the pull rod 202 is located at the deepest position capable of extending into the fixed cylinder 201, one end of the positioning column 206 abuts against the positioning groove 202a-3 to prevent the piston 209 from moving away from the bottom of the fixed cylinder 201, and the positioning column 206 has a limiting effect on the vertical surface 202a-2 at this time; when the pull rod 202 needs to be pulled out for a certain height, the rotating knob 208b drives the rotating member 208 to rotate, at this time, the overlapped position of the inclined groove 208a and the long groove 205b moves towards the direction away from the positioning groove 205a, until one end of the cross rod 206a moves to the horizontal groove 208a-2, and the rotation is stopped, then the cross rod 206a cannot fall back under the block of the horizontal groove 208a-2, and at the same time, the positioning column 206 has been separated from the positioning tooth 202a and loses the limiting effect on the pull rod 202, so under the elastic force of the third spring 210, the piston 209 and the pull rod 202 pop out outwards, but because the volume between the piston 209 and the fixed cylinder 201 is increased, air can only be fed from the position of the vent hole 209a, and the flow of the vent hole 209a is far smaller than the flow when the one-way valve is opened, so the pull rod 202 can only move slowly, when the height of the pull rod 202 is proper, the rotating knob, the cross bar 206a enters the lifting groove 208a-1, and under the elastic force of the second spring 207, the positioning column 206 abuts against the corresponding positioning groove 205a to prevent the pull rod 202 from moving, so that the fixing of the output fixing unit 200 is completed, and at this time, the operator can operate the output fixing unit 200 to fix by pulling the movable plate 203.
Preferably, rubber sealing rings 109 are fixedly connected to the joints between the mounting shell 101 and the output connecting line 106 and between the mounting shell 101 and the input connecting line 107.
