The upper ends of the front plate 1 and the rear plate 2 are not in direct contact, and the upper end of the rear plate 2 is not provided with a protrusion, and the sealing gasket 3 is made of hard rubber material, so that the protrusions provided on the sealing gasket 3 and the rear plate 2 can provide a supporting effect for the smooth upper and lower ends of the screw 9. The top and bottom ends of the front plate 1 are fixedly connected with a sealing ring 5, and the inner wall of the sealing ring 5 contacts the outer wall of the straight rod 6, so that the front plate 1 and the straight rod 6 are more tightly fitted through the sealing ring 5, and the airtightness between the front plate 1 and the straight rod 6 is strengthened.

[0028] Reference Figure 2-Figure 4The upper and lower ends of the front plate 1 are rotatably connected with screw rods 9, so that the rotating screw rods 9 drive the movable plate 13 to move up and down to accurately adjust the position of the movable plate 13. The inner wall of the front plate 1 is provided with a slide groove 7, and the inner wall of the slide groove 7 is slidably connected with a support rod 8, so that the support rod 8 can only move laterally along the slide groove 7 to provide a guide for the support rod 8.

[0029] Reference Figure 5-Figure 7 The inner wall of the support rod 8 is slidably connected with a telescopic rod 17, so that the length of the entire support rod 8 and the telescopic rod 17 can be adjusted and changed. The outer wall of the telescopic rod 17 is provided with a notch, so that the limit block 15 can be slidably connected through the notch to play a fixing role. The inner wall of the notch is slidably connected with the limit block 15, so that the support rod 8 and the telescopic rod 17 can be fixed through the limit block 15 and the notch. The inner wall of the limit block 15 is elastically connected to the inner wall of the telescopic rod 17 through a spring 16, so that the limit block 15 and the notch of the telescopic rod 17 can be fixed by the spring 16 without being affected by other external forces. One end of the spring 16 is fixedly connected to the inner wall of the telescopic rod 17, and the other end of the spring 16 is fixedly connected to the inner wall of the limit block 15, so that the limit block 15 can maintain the plug-in relationship with the limit opening 14 without being affected by other external forces through the spring 16 to keep the support rod 8 and the telescopic rod 17 relatively stable. The outer wall of the support rod 8 is provided with a limit opening 14, so that the limit block 15 can fix the length of the support rod 8 and the telescopic rod 17 by plugging with the limit opening 14 to maintain the fixing effect. The outer wall of the limit block 15 is plugged with the limit opening 14, so that the limit block 15 provides a fixing effect for the telescopic rod 17 and the support rod 8.

[0030] Working principle: In order to meet the user's requirements for different heights when using the lifting rod, the upper and lower positions of the front plate 1 and the rear plate 2 can be freely adjusted. The front plate 1 can be pushed up and down repeatedly on the straight rod 6, so that the rotation shaft 12 rotates to drive the soft rubber ring 10 to roll on the straight rod 6. When the external force is stopped, the soft rubber ring 10 contracts to stop the rotation of the rotation shaft 12, so that the soft rubber ring 10 is fixed on the straight rod 6 to keep the front plate 1 and the rear plate 2 stable.

[0031] After long-term use, the soft rubber ring 10 will rub against the straight rod 6 during movement, causing the soft rubber ring 10 to shrink, resulting in a larger distance between the support rods 8. This will make it difficult for the front plate 1 and the rear plate 2 to be firmly fixed on the straight rod 6 during the movement of the outer wall of the straight rod 6. It is necessary to rotate the screw 9 to reduce the distance between the support rods 8. First, rotate the screw 9 to drive the movable plate 13 to move downward, so that the movable plate 13 drives the distance between the support rods 8 to shrink through the hinged beam 11, thereby increasing the friction between the soft rubber ring 10 and the straight rod 6, and causing greater force between the soft rubber ring 10 and the straight rod 6, making the front plate 1 and the rear plate 2 more stable.

[0032] In order to replace the soft rubber ring 10, it is necessary to first disassemble the rear plate 2, remove the screws 4, remove the rear plate 2 and the sealing gasket 3, and after removing the rear plate 2, press the limit block 15 to release the fixing effect of the telescopic rod 17, and manually control the telescopic rod 17 to slide into the inner wall of the support rod 8, so as to remove the support rod 8 adjacent to the rear plate 2, separate the support rod 8 from the hinged beam 11, and achieve the effect of disassembling the soft rubber ring 10, and then remove the front plate 1 from the straight rod 6, and replace the other group of soft rubber rings 10.

[0033] When assembling the front plate 1 and the rear plate 2, first install the support rod 8, the rotating shaft 12 and the soft rubber ring 10 near the front plate 1, fix the front plate 1 as a whole on the straight rod 6, insert the screw 9 into the front plate 1, press the support rod 8 on one side of the rear plate 2 against its corresponding limit block 15, take out the telescopic rod 17 from the support rod 8 and insert the support rod 8 into the hinged beam 11 to assemble it, connect the support rod 8 into the slide groove 7, fit the sealing gasket 3 with the front plate 1, plug the rear plate 2 with the front plate 1, and fix the sealing gasket 3 of the rear plate 2 to the front plate 1 with the screws 4 to complete the installation.

[0034] 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 substitutions for some of the technical features therein.
