[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Embodiment

[0023] Please refer to Figures 1 - 4 , a stainless - steel fastener with a relatively flexible use length, including a stop block 100 and a threaded column 200. A sleeve 300 is fixedly connected to the side of the stop block 100, and a fixed cylinder 400 is fixedly connected to the side of the threaded column 200. The sleeve 300 is slidably connected to the outside of the fixed cylinder 400;

[0024] An adjustment component 500 is arranged between the sleeve 300 and the fixed cylinder 400. The adjustment component 500 includes a torsion spring rod 501. The torsion spring rod 501 is located on the side of the sleeve 300, and the torsion spring rod 501 is rotatably connected to the sleeve 300. A transmission rod 502 is fixedly connected to the outside of the torsion spring rod 501. When it is necessary to adjust the distance between the stop block 100 and the threaded column 200, by rotating the torsion spring rod 501, the torsion spring rod 501 drives the transmission rod 502 fixedly connected thereto to rotate. A clamping block 503 is fixedly connected to the side of the transmission rod 502. When the transmission rod 502 rotates, the transmission rod 502 drives the clamping block 503 fixedly connected thereto to rotate. A first clamping groove 504 is formed on the side of the fixed cylinder 400, and a through - second clamping groove 505 is formed on the side of the sleeve 300. There are multiple groups of the first clamping grooves 504, and the cross - sectional shapes of the first clamping groove 504, the second clamping groove 505 and the clamping block 503 are all mutually adapted. When the clamping block 503 rotates, the clamping block 503 immediately moves out of the first clamping groove 504 on the fixed cylinder 400, and at the same time, the clamping block 503 also moves out of the second clamping groove 505 on the sleeve 300, thus canceling the restriction between the sleeve 300 and the fixed cylinder 400. At this time, the sleeve 300 can be pulled to slide on the fixed cylinder 400. An air pressure chamber 506 is fixedly connected to the inside of the clamping block 503. One end of the air pressure chamber 506 is slidably connected to a pull rod 507, and the other end of the air pressure chamber 506 is fixedly connected to a suction cup 508. After the adjustment is completed, the torsion spring rod 501 is released, and the clamping block 503 immediately resets under the action of the torsion spring rod 501, and the suction cup 508 moves to the inside of the first clamping groove 504 for adsorption. Subsequently, by pulling the pull rod 507, the gas in the suction cup 508 fixedly connected to the air pressure chamber 506 can be evacuated through the air pressure chamber 506 slidably connected to the pull rod 507, improving its adsorption effect. In this way, the adjustment of the distance between the stop block 100 and the threaded column 200 can be quickly completed, and the stability of the device after adjustment is improved, and the operation is more convenient.

[0025] When in use, when it is necessary to adjust the spacing between the stopper 100 and the threaded column 200, the torsion spring rod 501 is rotated, so that the torsion spring rod 501 drives the transmission rod 502 fixedly connected thereto to rotate, and the transmission rod 502 drives the clamping block 503 fixedly connected thereto to rotate, and at this time, the clamping block 503 is immediately moved out of the clamping groove 1 504 on the fixed cylinder 400, and at the same time, the clamping block 503 is also moved out of the clamping groove 2 505 on the sleeve 300, thereby eliminating the sleeve 300 and the fixed cylinder 400. The restriction between them can be eliminated. At this time, the sleeve 300 can be pulled to slide on the fixed cylinder 400. After the adjustment is completed, the torsion spring rod 501 is released, and the block 503 is immediately reset under the action of the torsion spring rod 501. The suction cup 508 moves into the card slot 1 504 for adsorption. Then, by pulling the pull rod 507, the gas in the suction cup 508 fixedly connected to the air pressure chamber 506 can be extracted through the air pressure chamber 506 slidably connected to the pull rod 507, thereby improving its adsorption effect. Example

[0026] See also Figures 1 - 4 On the basis of the first embodiment, a limit assembly 600 is provided on the clamping block 503, and the limit assembly 600 includes a fixed plate 601, which is located at the side of the transmission rod 502 and is in a fixed connection state with the transmission rod 502. The side of the fixed plate 601 is connected with a clamping rod 603 by setting a spring 602. Before the pull rod 507 needs to be moved, the clamping rod 603 is pulled, and the clamping rod 603 squeezes the spring 602 and moves. A clamping groove 3 604 is provided on the side of the pull rod 507, and the cross-sectional shape of the clamping groove 3 604 is adapted to the cross-sectional shape of the clamping rod 603. When the clamping rod 603 moves, the clamping rod 603 is immediately moved out of the clamping groove 3 604 on the pull rod 507, thereby canceling the restriction on the pull rod 507, reducing the possibility of accidentally touching the pull rod 507 when the pull rod 507 is not needed, and making the use of the device more stable.

[0027] During use, based on the first embodiment, before the pull rod 507 needs to be moved, the card rod 603 is pulled, and the card rod 603 then squeezes the spring 602 and moves, so that the card rod 603 is immediately moved out of the card slot three 604 on the pull rod 507, thereby removing the restriction on the pull rod 507.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
