It also includes a sleeve 4 movably sleeved on the outside of the support body 1 and multiple support rods 2, and the sleeve 4 is used to limit the multiple support rods 2; a positioning structure 5 is used to position the sleeve 4, and multiple positioning structures 5 equidistantly distributed around the circumference are installed inside the sleeve 4; an adjustment component 6 is used to drive the positioning structure 5 to rotate, and the adjustment component 6 is installed on the outside of the sleeve 4.

[0029] Working principle for convenient storage or carrying: when storing or carrying the bracket main body 1, the personnel first rotate the four support rods 2 close to the bracket main body 1, and then move the sleeve 4 downward, so that the sleeve 4 is sleeved on the outside of the four support rods 2 to limit the four support rods 2, so that in the process of storing or carrying the bracket main body 1, the four support rods 2 on the outside of the bracket main body 1 are prevented from automatically opening and accidentally injuring oneself or others, and the four support rods 2 are positioned on the outside of the bracket main body 1 by the sleeve 4, which can reduce the volume of the bracket main body 1, thereby making the bracket main body 1 convenient to store or carry.

[0030] Embodiment 2

[0031] See also Figure 3 , Figure 4 This embodiment further explains Example 1. The positioning structure 5 includes a cam 501 installed on the inner wall of the sleeve 4. A limit groove 502 is provided inside the sleeve 4 corresponding to the installation position of the cam 501. The limit groove 502 can limit the rotation angle of the cam 501. A positioning shaft 503 is fixedly passed through the inside of the cam 501. The positioning shaft 503 can prevent the cam 501 from being separated from the limit groove 502, and the cam 501 is rotatably connected to the sleeve 4 through the limit groove 502 and the positioning shaft 503.

[0032] See also Figure 4 Two symmetrically distributed coil springs 504 are fixedly sleeved on the outer side of the positioning shaft 503, and the outer end of the coil spring 504 is fixedly connected to the sleeve 4. The coil spring 504 can drive the cam 501 to rotate. A tooth plate 7 is fixedly embedded on the side of the support rod 2 away from the bracket body 1. The tooth plate 7 can increase the friction resistance between the cam 501 and the support rod 2, and the tooth plate 7 is close to the upper end of the support rod 2. A protrusion 8 is fixedly embedded on the outer side of the bracket body 1 on the upper side of the hinge seat 3.

[0033] See also Figure 2, the number of the first toothed plates 7 and the bumps 8 is equal to the number of the positioning structures 5. A second toothed plate 9 is fixedly installed on the side of the bump 8 away from the bracket main body 1. The second toothed plate 9 can increase the frictional resistance between the cam 501 and the bump 8. The connection modes between the cam 501 and the first toothed plate 7 and the second toothed plate 9 are both movable abutments. Two symmetrically distributed stoppers 10 are fixedly embedded on the outer side of the bracket main body 1 above the bump 8. The stoppers 10 can prevent the sleeve 4 from detaching from the bracket main body 1, and the upper end of the sleeve 4 is in movable abutment with the stoppers 10.

[0034] In this embodiment: when moving the sleeve 4 downward, the cam 501 can rotate inside the limit rotating groove 502 under the blockage of the second toothed plate 9 or the first toothed plate 7. At this time, the positioning structure 5 will not cause any obstruction to the downward movement of the sleeve 4. Personnel can move the sleeve 4 downward with one hand, which is more convenient. When the sleeve 4 is sleeved on the outer sides of the four support rods 2, the cam 501 cannot rotate downward under the blockage of the limit rotating groove 502. The cam 501 abuts against the first toothed plate 7 to block the sleeve 4, preventing the sleeve 4 from moving upward on the outer sides of the support rods 2, thereby enhancing the positioning stability of the sleeve 4 to the four support rods 2.

[0035] Embodiment Three

[0036] Please refer to Figure 6 , this embodiment further illustrates other embodiments. The adjusting assembly 6 includes a first collar 601 movably sleeved on the outer side of the sleeve 4. The first collar 601 can move up and down on the outer side of the sleeve 4. A second collar 602 is fixedly sleeved on the outer side of the sleeve 4.

[0037] Please refer to Figure 6 , the second collar 602 is located above the first collar 601. A plurality of pin blocks 603 equal in number to the positioning structures 5 are fixedly connected to the inner side of the first collar 601. The pin blocks 603 can prevent the first collar 601 from detaching from the sleeve 4. A pull rope 604 is fixedly embedded on the side of the pin block 603 away from the first collar 601.

[0038] Please refer to Figure 5 , one end of the pull rope 604 away from the pin block 603 is fixedly connected to the cam 501. The upward movement of the pull rope 604 can drive the cam 501 to rotate. The pull rope 604 is in movable contact with the sleeve 4 through the limit straight groove 605.

[0039] In this embodiment: when releasing the restriction of the sleeve 4 on the four support rods 2, personnel press the second collar 602 with two thumbs, hook the first collar 601 with two index fingers, and drive the first collar 601 to move upward. During the upward movement of the first collar 601 and the pin blocks 603, the cam 501 can be driven to rotate upward through the pull rope 604, which is beneficial to releasing the restriction of the cam 501 on the sleeve 4. At this time, the sleeve 4 can be easily moved upward to release the limit of the sleeve 4 on the four support rods 2.
