By setting a rotatable rotating rod 12 in the middle of the connecting column 1, when the overall height of the counterweight ball 110 needs to be adjusted, the staff can insert the tool into the inner wall of the inner groove 13, at this time, the end of the tool will contact the sliding rod 14 and squeeze the sliding rod 14, and when the sliding rod 14 slides on the inner wall of the rotating rod 12, it will simultaneously push the slider 1 5 moves toward the outside, and during the movement, the middle part of the spring 16 is stretched, and the end of the latch 17 is separated from the inner wall of the slot 18, and then the rotating rod 12 is rotated as a whole, and the connecting rope 19 is wound around the middle part of the rotating rod 12, so as to adjust the height of the counterweight ball 110. After the position adjustment of the counterweight ball 110 is completed, the staff can separate the tool from the inner wall of the inner groove 13, so that after the slide bar 14 loses its supporting force, the latch 17 can be clamped at the designated inner wall of the slot 18 again, and the counterweight ball 110 can cooperate with the counterweight ball 110 after the connecting column 1 is subjected to the external force. The ball 110 can offset the shaking force, thereby achieving a balanced effect when the connecting column 1 is placed. This step, combined with the setting of the counterweight ball 110, can improve the stability of the connecting column 1 as a whole during operation, and reduce the problem of strong wind force in the outside world causing the connecting column 1 to shake and shift in position. At the same time, a rotating rotating rod 12 is set to improve the flexibility of the position of the counterweight ball 110 during operation, and the base 11 can be stored, thereby reducing the problem of the counterweight ball 110 frequently hitting the inner wall of the connecting column 1 when the connecting column 1 is transported as a whole, and reducing the wear on the middle part of the counterweight ball 110.

[0027] like Figure 1-3As shown, the outer wall of the connecting column 1 is rotatably connected to the rotating shaft 2; a shielding cloth 21 is fixedly connected to the middle of the rotating shaft 2; a connecting cloth 22 is fixedly connected to the end of the shielding cloth 21; two sets of counterweights 23 are fixedly connected to the bottom of the connecting cloth 22; a friction pad 24 is fixedly connected to the middle of the counterweight 23; when working, the shielding cloth 21 is arranged at the end of the connecting column 1, so that when the rotating rod 12 is not rotated as a whole, the middle of the shielding cloth 21 is straightened in cooperation with the two sets of counterweights 23, so that the falling shielding cloth 21 can contact multiple card slots 18 performs shielding work, and the slider 15 as a whole can support the middle part of the shielding cloth 21 and make it bulge when it moves. This step, combined with the setting of the shielding cloth 21, can reduce the problem of blockage caused by the accumulation of sand in the middle part of the slot 18 when the connecting column 1 is exposed to the outside world for a long time, thereby improving the stability of the subsequent matching and fixing of the pin 17 and the slot 18. At the same time, the two sets of counterweight blocks 23 can reduce the problem of frequent shaking of the shielding cloth 21 when it is working.

[0028] like Figure 3-5 As shown, two groups of brackets 3 are fixedly connected to the inner wall of the connecting column 1; the end of the bracket 3 is fixedly connected to a limiting sleeve 31, and the connecting rope 19 is arranged on the inner wall of the limiting sleeve 31; two groups of vertical rods 32 are fixedly connected to the bottom of the limiting sleeve 31; the end of the vertical rod 32 is fixedly connected to a scraper 33, and the two groups of scrapers 33 are staggered; when working, a limiting sleeve 31 is arranged on the inner wall of the connecting column 1, and the limiting sleeve 31 can limit the working position of the connecting rope 19, so that the connecting rope 19 will first pass through the middle part of the limiting sleeve 31 when sliding up and down, and the two groups of scrapers 33 are arranged at the same time, The dust accumulated in the middle part of the sliding connecting rope 19 continues to scrape off the dust. This step cooperates with the setting of the limiting sleeve 31 to improve the stability of the connecting rope 19 during use, reduce its frequent shaking, and make it difficult for the counterweight ball 110 to reinforce the connecting column 1. Under the action of the scraper 33, the cleanliness of the middle part of the connecting rope 19 can be improved, and the accumulation and corrosion of the middle part of the connecting rope 19 by more impurities can be reduced.

[0031] like Figure 3-4 As shown, two groups of partitions 6 are fixedly connected to the middle of the rotating rod 12, and the two groups of partitions 6 are symmetrically arranged; when working, by arranging two groups of partitions 6 in the middle of the rotating rod 12, the connecting rope 19 can be limited by the two groups of partitions 6 when it is wrapped and stored in the middle of the rotating rod 12. This step cooperates with the two groups of partitions 6 to reduce the phenomenon that the connecting rope 19 is loose and unfolded to both sides when it is stored, and reduces the problem of the connecting rope 19 being entangled when it is stored.

[0032] like Figure 4 As shown, a protective pad 7 is provided at the end of the slide rod 14; during operation, the protective pad 7 is provided at the end of the slide rod 14, so that when the staff presses the tool, it will first contact the middle of the protective pad 7 and squeeze the slide rod 14 to slide. This step can reduce the wear on the end of the slide rod 14 under the action of the soft material protective pad 7, and at the same time increase the speed of replacing and maintaining the protective pad 7.

The connecting rope 19 can be wound around the middle part of the rotating rod 12 to adjust the height of the counterweight ball 110. After the position of the counterweight ball 110 is adjusted, the staff can disengage the tool from the inner wall of the inner groove 13, so that after the sliding rod 14 loses its supporting force, the latch 17 can be clamped on the inner wall of the designated slot 18 again. The counterweight ball 110 can be used to offset the shaking force when the connecting column 1 is subjected to external force as a whole, thereby achieving the effect of balancing the connecting column 1 when it is placed. By providing a shielding cloth 21 at the end of the connecting column 1, when the rotating rod 12 is not rotated as a whole, the two sets of counterweight blocks 23 can be used to The middle part of the shielding cloth 21 is straightened so that the falling shielding cloth 21 can shield the multiple slots 18, and the slider 15 can support the middle part of the shielding cloth 21 and make it bulge when it moves as a whole. A limiting sleeve 31 is provided on the inner wall of the connecting column 1, and the limiting sleeve 31 can limit the working position of the connecting rope 19, so that the connecting rope 19 will first pass through the middle part of the limiting sleeve 31 when sliding up and down.

The connecting rope 19 contacts the inner wall of the groove 4, and in the process of pulling the connecting rope 19, it will drive multiple rotating beads 41 to rotate under the action of friction. By providing a storage box 5 on the top of the connecting column 1, the staff can place an appropriate amount of weight on the inner wall of the storage box 5 after the connecting column 1 is installed, and make contact with the top of the cushion 51. By providing two groups of partitions 6 in the middle of the rotating rod 12, the connecting rope 19 can be limited by the two groups of partitions 6 when it is wrapped and stored in the middle of the rotating rod 12.
