Limiting holes 4 11 are provided on the two side surfaces of the base plate 1, and limiting holes 3 10 are provided on the surface of the curved arm 2 9, and the type and specification of the limiting holes 4 11 are consistent with those of the limiting holes 3 10. After aligning the limiting holes 1 7 with the limiting holes 2 8, the plug is passed through the limiting holes 1 7 and inserted into the inside of the limiting holes 2 8 to fix the position of the unfolded curved arm 1 6, and then the curved arm 2 9 is rotated, and the limiting holes 3 10 are made to correspond to the positions of the limiting holes 4 11, and the plug is passed through the limiting holes 3 10 and inserted into the inside of the limiting holes 4 11 to fix the position of the unfolded curved arm 2 9. At this time, the curved arm 1 6 and the curved arm 2 9 can provide support for the device, thereby increasing the ground clearance of the base plate 1 and preventing the base plate 1 from being placed directly on the ground.

[0022] Among them, an inner rod 17 is slidably inserted inside the connecting tube 14, and the model and specification of the inner rod 17 are consistent with those of the limit head 12. A convex strip 19 is fixedly connected to the inner wall of the connecting tube 14. A slot 18 is provided on the surface of the inner rod 17, and the slot 18 is slidably engaged with the convex strip 19. The inner rod 17 is threadedly sleeved on the surface of the threaded rod 16. The threaded rods 16 at both ends of the rotating rod 15 are rotated by hand, thereby driving the inner rod 17 sleeved on its surface to move inside the connecting tube 14, so that one end of the inner rod 17 is inserted into the inside of the limit head 12, thereby fixing the position between the limit head 13 and the limit head 12. At this time, the connecting tube 14 can be lifted by hand.

[0023] Among them, columns 3 are slidably inserted at the four corners of the base plate 1, and a rain shield 4 is fixedly connected to the top of the column 3. The rain shield 4 is located directly above the broadcasting machine 2. Locking bolts 5 are threadedly inserted at both ends of the base plate 1, and the end of the locking bolt 5 abuts against the surface of the column 3. The column 3 is inserted at the four corners of the base plate 1, and the locking bolt 5 is rotated so that the end of the locking bolt 5 fits tightly with the surface of the column 3, thereby fixing the position of the rain shield 4 directly above the broadcasting machine 2, and the rain shield 4 can prevent rain from falling on the broadcasting machine 2.

[0024] Working principle: when the device is in use, after aligning the limiting hole 1 7 with the limiting hole 2 8, the plug is inserted through the limiting hole 1 7 and inserted into the inside of the limiting hole 2 8 to fix the position of the unfolded curved arm 1 6, and then the curved arm 2 9 is rotated, and the limiting hole 3 10 is aligned with the position of the limiting hole 4 11, and the plug is inserted through the limiting hole 3 10 and inserted into the inside of the limiting hole 4 11 to fix the position of the unfolded curved arm 2 9. At this time, the curved arm 1 6 and the curved arm 2 9 can provide support for the device, thereby increasing the ground clearance of the base plate 1 and preventing the base plate 1 from being placed directly on the ground. The column 3 is inserted at the four corners of the base plate 1, and the locking bolt 5 is rotated so that the end of the locking bolt 5 is tightly fitted with the surface of the column 3, thereby blocking the rain. The position of the board 4 is fixed just above the broadcasting machine 2, and the rain shield 4 can prevent rain from falling on the broadcasting machine 2, while preventing water on the ground from entering the inside of the broadcasting machine 2. The crank arm 1 6 and the crank arm 2 9 are rotated so that the limit head 12 and the limit head 2 13 are both located at the top of the rain shield 4, and the positions of the crank arm 1 6 and the crank arm 2 9 are aligned. At this time, the threaded rods 16 at both ends of the rotating rod 15 are driven by the human hand to rotate, thereby driving the inner rod 17 sleeved on its surface to move inside the connecting tube 14, so that one end of the inner rod 17 is inserted into the inside of the limit head 12, thereby fixing the position between the limit head 2 13 and the limit head 1 12. At this time, the human hand can hold the connecting tube 14 to lift the device.
