When the two threaded blocks 6 move, the angle between the first support bar 7 and the second support bar 8 changes, thereby adjusting the distance between the two vertical frames 1 on the left and right sides. After the adjustment is completed, the length of the telescopic frame 9 is adjusted according to the distance between the two vertical frames 1, and it is installed in the corresponding position by bolts, and the horizontal frame 10 and the mounting plate 19 are installed. When the support frame is not needed, the angle between the first support bar 7 and the second support bar 8 is adjusted to the minimum state, thereby reducing the device to make it easy to store and move.

[0022] The three outer surfaces of the vertical frame 1 away from the first support bar 7 and the second support bar 8 are fixedly connected to the first rotating seat 11, the outer surface of the first rotating seat 11 is rotatably connected to the first rotating block 12, the outer surface of the first rotating block 12 is threadedly connected to the threaded rod 13, the outer surface of the threaded rod 13 is threadedly connected to the threaded tube 14, the outer surface of the threaded tube 14 is rotatably connected to the second rotating block, the outer surface of the second rotating block is rotatably connected to the second rotating seat 15, and the bottom outer surface of the second rotating seat 15 is fixedly connected to the stabilizing plate 16.

When the two threaded blocks 6 move, the angle between the first support bar 7 and the second support bar 8 changes, thereby adjusting the distance between the two vertical frames 1 on the left and right sides. After the adjustment is completed, the length of the telescopic frame 9 is adjusted according to the distance between the two vertical frames 1, and it is installed in the corresponding position by bolts, and the horizontal frame 10 and the mounting plate 19 are installed.
