[0041] The positioning assembly 8 is disposed on the frame 5 and is used to position the fixed shaft 70. After the angle is adjusted, the fixed shaft 70 can be directly fixed by the positioning assembly 8 to keep it stationary.

[0042] In one embodiment, the first clamping assembly 3 includes a fixing frame 31 connected to the connecting rod 30, a bidirectional threaded rod 32 is rotatably arranged in the fixing frame 31, a fixing handle 33 is arranged at one end of the bidirectional threaded rod 32, positioning clamps 34 are arranged at both ends of the fixing frame 31, and a movable slider 35 sleeved on the bidirectional threaded rod 32 is arranged at one end of the positioning clamp 34;

[0043] When in use, the auxiliary device can be fixed to the grid in advance by clamping the positioning clamp 34 on the first rod 1 and then rotating the fixing handle 33. The fixing handle 33 drives the bidirectional threaded rod 32 to rotate, so that the two positioning clamps 34 can move inward at the same time and clamp on the first rod 1 to complete the initial fixation.

[0044] In one embodiment, the telescopic assembly 4 includes a fixed sleeve 41 connected to the connecting rod 30, a telescopic rod 42 is movably arranged in the fixed sleeve 41, a groove is provided on the telescopic rod 42, a limit rod 43 is slidably arranged in the groove, a limit hole matched with the limit rod 43 is provided on the side wall of the fixed sleeve 41, and a limit spring 44 connected to the limit rod 43 is also arranged in the groove;

[0053] When the second end cover 72 is pressed inward, the second end cover 72 will push the movable ring 80, causing the movable ring 80 to move in the opposite direction of the positioning ring 701. At the same time, the driving rod 85 will also be deflected, and the driving rod 85 will drive the positioning block 83 to slide and compress the return spring 84. After the second end cover 72 is fully pressed in, the movable ring 80 will be attached to the positioning ring 701, and the positioning block 83 will also be completely separated from the positioning ring 701. At this time, the end cover can be rotated to drive the second clamping assembly 6 to rotate through the fixed rotating shaft 70. After the adjustment is completed, the pressure on the second end cover 72 is released, the second end cover 72 bounces upward and separates from the first end cover 71. At the same time, the movable ring 80 will also slide with the second end cover 72, and the return spring 84 will also push the positioning block 83 to be inserted into the positioning ring 701, fix the fixed rotating shaft 70, and complete the locking.

[0054] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
