An outer rod 6 is provided outside the support column 2, and a crossbar 16 is provided on one side of the outer rod 6. A second movable block 18 is fixedly connected to the left side of the crossbar 16, and a second movable block 18 is fixedly connected to the bottom end of the crossbar 16. Two fixed seats 17, with a fixed rod 15 movably hinged to the front end of the second fixed seat 17, and a first fixed seat 14 movably hinged to the bottom end of the fixed rod 15. A first movable block 11 is fixedly connected to one side of the first fixed seat 14. A second reserved groove 20 and a fourth assembly hole 24 are respectively provided inside the front end of the outer rod 6. A fixed shaft 19 is transversely arranged inside the second reserved groove 20. A second double-ended screw 12 is transversely arranged inside the fourth assembly hole 24. A second locking nut 13 is movably connected to the outside of the second double-ended screw 12.

[0025] The front and rear ends of the second double-ended screw 12 pass through the interior of the first movable block 11. The first movable block 11 is slidably engaged with the outside of the outer rod 6, and the second movable block 18 is engaged with the outside of the outer rod 6.

[0026] Two sets of second fixing seats 17 are provided, and the second fixing seats 17 are symmetrically distributed at the front end and rear end of the bottom of the crossbar 16;

[0027] The front and rear ends of the fixed shaft 19 are fixedly connected to the front and rear ends of the second movable block 18, respectively. The second movable block 18 can rotate outside the outer rod 6 via the fixed shaft 19.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, during unfolding, the second movable block 18 can be rotated on the outer rod 6 to rotate the crossbar 16 to one side. At this time, the first movable block 11 will slide on the outer rod 6. When it slides to the fourth assembly hole 24, the second double-ended screw 12 will pass through the inside of the second reserved slot 20. The second locking nut 13 will be screwed on the outside of the second double-ended screw 12 to fix it, thereby facilitating quick unfolding, assembly and fixation.

[0029] At least ten sets of second assembly holes 5 are provided, and the second assembly holes 5 are evenly distributed on one side of the support column 2.

[0030] The bottom end of the outer rod 6 is provided with a first reserved groove 10, and the outer rod 6 is provided with a third assembly hole 9 on both sides. The third assembly hole 9 and the second assembly hole 5 are transversely provided with a first double-ended screw 7. The first double-ended screw 7 is movably connected to the outside of a first locking nut 8. The outer rod 6 is movably sleeved on the outside of the support column 2 through the first reserved groove 10. The support column 2 is detachable from the outer rod 6 through the first double-ended screw 7 and the first locking nut 8.

[0031] Specifically, such as Figure 1 and Figure 4 As shown, when the height needs to be adjusted, the outer rod 6 can be moved upwards. When moving to the required height, the first double-ended screw 7 is passed horizontally through the second mounting hole 5 and the third mounting hole 9, and then the first locking nut 8 is screwed on the outside of the first double-ended screw 7 to fix it, thereby facilitating and stabilizing the adjustment of the required bracket height.

[0032] A movable groove 21 is provided inside one side of the crossbar 16, and an extension rod 22 is provided inside the movable groove 21. A fixing block 23 is fixedly connected to one side of the extension rod 22.

[0034] Specifically, such as Figure 1 and Figure 3 As shown, when the length of the crossbar 16 needs to be adjusted, the fixed block 23 can be rotated. At this time, the extension rod 22 can rotate inside the movable groove 21 and extend outward, so that the length can be easily adjusted laterally.

[0035] Working principle: When using this utility model, firstly, during unfolding, the second movable block 18 can be rotated on the outer rod 6 to rotate the crossbar 16 to one side. At this time, the first movable block 11 will slide on the outer rod 6. When it slides to the fourth assembly hole 24, the second double-ended screw 12 passes through the inside of the second reserved groove 20. The second locking nut 13 is screwed on the outside of the second double-ended screw 12 to fix it, thus facilitating quick unfolding, assembly and fixation. After that, when it is necessary to adjust the length of the crossbar 16, the fixing block 23 can be rotated. At this time, the extension rod 22 can rotate inside the movable groove 21 and extend outward, thus facilitating lateral adjustment according to the length. Finally, when it is necessary to adjust the height, the outer rod 6 can be moved upward. When moving to the required height, the first double-ended screw 7 is horizontally passed through the second assembly hole 5 and the third assembly hole 9, and the first locking nut 8 is screwed on the outside of the first double-ended screw 7 to fix it, thus facilitating stable adjustment of the required bracket height.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
