[0035] refer to Figure 2The adjustment component includes two connecting shafts 12, two plugging heads 13, a pressing rod 14, two springs 15, two rubber sleeves 16 and two air holes 17. The middle part of the sealing sleeve 11 is slidably connected with the connecting shaft 12, the bottom end of the connecting shaft 12 is fixedly connected with the plugging head 13, the top of the two plugging heads 13 is fixedly connected with the pressing rod 14, and the spring 15 is sleeved on the outside of the connecting shaft 12. When the pressing rod 14 is pressed, the connecting shaft 12 and the plugging head 13 move up and down, and the rubber sleeve 16 and the spring 15 drive the pressing rod 14 to reset. The left and right sides of the pressing rod 14 are fixedly connected with rubber sleeves 16. The middle part of the right side of the rubber sleeve 16 is provided with an air hole 17. Air is released through the air hole 17 to prevent the rubber sleeve 16 from increasing the resistance to pressing the rod 14, and the rubber sleeve 16 can protect the spring 15.

[0036] The outside of the disc rod 5 is slidably connected to the inner wall of the long cylinder 10, and the disc rod 5 blocks the air flow outlet at the bottom end of the long cylinder 10. The top of the plugging head 13 contacts the top of the inner wall of the long cylinder 10, and cooperates with the long cylinder 10 to realize that the long cylinder 10 is a closed space. The outside of the connecting shaft 12 is slidably connected to the middle inner wall of the telescopic cylinder 6 to realize the sliding of the connecting shaft 12. One end of the spring 15 is fixedly connected to the left and right sides of the bottom end of the push rod 14, and the bottom end of the spring 15 is fixedly connected to the middle of the top end of the sealing sleeve 11. The spring 15 uses the top end of the sealing sleeve 11 as a support to drive the push rod 14 to reset.

[0037] refer to Figure 3 、 Figure 4 The top middle part of the sleeve block 19 is fixedly connected with a telescopic rod 20, and the left and right ends of the telescopic rod 20 are fixedly connected with an adjusting rod 21. The outer sleeve of the telescopic rod 20 is provided with a spring 22, one end of the spring 22 is fixedly connected to the right side of the inner wall of the sleeve block 19, and the other end of the spring 22 is fixedly connected to the right side of the left adjusting rod 21. The spring 22 uses the inner wall of the sleeve block 19 as a support to pull the adjusting rod 21 on one side against the telescopic rod 20 in the sleeve block 19, thereby increasing the self-locking ability of the telescopic rod 20. The interior of the sleeve block 19 is slidably connected with a block 23, and a through groove 24 is provided at the middle and rear end of the block 23. A connecting rod 25 is fixedly connected to the front side of the block 23, and the tops of the two connecting rods 25 are fixedly connected It is connected to a cross bar 26, and the outer part of the telescopic rod 20 is slidably connected to the inner wall of the through groove 24. The outer part of the spring 22 is slidably connected to the inner wall of the through groove 24. The cross bar 26 is pulled to drive the connecting rod 25 and the rear inclined surface of the block 23 fixed with the connecting rod 25 to slide on the inner wall of the sleeve block 19, so that the middle part of the sleeve block 19 is restricted and the telescopic rod 20 slides in the through groove 24 of the block 23, so that the through groove 24 is against the top of the inner wall of the through groove 24 of the block 23, and then the telescopic rod 20 is inserted into the through groove 24 through the right side of the inner wall of the sleeve block 19 to support the adjusting rod 21 against the block 23, so that the rear inclined surface of the block 23 is against the inner wall of the sleeve block 19 for self-locking to support and fix the unfolded cross bar 26.

[0038] Working principle: When in use, first pull the cross bar 26 to drive the connecting rod 25 and the rear inclined surface of the block 23 fixed by the connecting rod 25 to slide on the inner wall of the sleeve block 19, so that the middle part of the sleeve block 19 is restricted by the telescopic rod 20 to slide in the through groove 24 of the block 23, so that the through groove 24 is against the top of the inner wall of the through groove 24 of the block 23, and then cooperate with the telescopic rod 20 to insert and pass through the through groove 24 through the right side of the inner wall of the sleeve block 19 to support the big adjustment rod 21 against the block 23, so that the rear inclined surface of the block 23 is against the inner wall of the sleeve block 19 to self-lock and support and fix the unfolded cross bar 26. When folding the cross bar 26, you only need to pull the cross bar 26 downward to complete the folding.

[0039] When the cross bar 26 is fixed, the user can adjust the height of the cross bar 26 according to his or her height requirements for better stretching. By pressing the push rod 14, the connecting shaft 12 at the bottom end of the push rod 14 is driven to quickly press against the plugging head 13 to open the through hole in the long cylinder 10, so that the air at the sealed position between the plugging head 13 and the bottom of the disc rod 5 can flow into the through hole 9 through the hole at the top of the long cylinder 10 and flow into the bottom cylinder 4, so that the telescopic cylinder 6 outside the plugging head 13 slides down the inner wall of the bottom cylinder 4 after the air pressure in the plugging head 13 and the disc rod 5 becomes smaller. Because the external fixed welding block 27 of the telescopic cylinder 6 is connected to the adjustment plate 2, and the adjustment plate 2 is indirectly connected to the cross bar 26, when the telescopic cylinder 6 descends, the cross bar 26 will also move and adjust synchronously.

[0040] When the user needs to raise the height of the cross bar 26, he only needs to press the push rod 14 multiple times to let the push rod 14 drive the blocking head 13 to repeatedly block the opening of the long tube 10, so that the airflow at the position of the long tube 10 can circulate with the airflow in the through hole 9. The blocking head 13 moves quickly to allow the airflow at the bottom of the bottom tube 4 to flow into the position of the long tube 10 through the through hole 9 to generate air pressure, so that the telescopic tube 6 is driven up by the air pressure to realize the rising of the adjustment plate 2 and the cross bar 26.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
