The guiding blocks can limit the positioning blocks and facilitate the person to slide the positioning blocks into the inner wall of the connecting groove. When the connecting frame contacts the connecting frame, the person rotates the connecting block, and the connecting block drives the connecting column to rotate. The connecting column drives the threaded rod to move away from the connecting block, and the threaded rod drives the clamping block to move away from the connecting block until the clamping block slides into the inner part of the positioning groove. At this time, it is folded into a T-shaped stage. By setting the connection structure,It has reached the point where it is convenient for personnel to quickly fold the folding bracket, and the folding bracket can be folded into a display stand, a T-stage, etc., thereby improving the applicability of the folding bracket.

[0033] Working principle: When a person needs to fold the folding bracket, the person can first drive the auxiliary column 322 to rotate by means of the rotating rod 323. The rotating rod 323 can facilitate the person to rotate the auxiliary column 322 and improve the operation convenience of the person. Then, the auxiliary column 322 drives the pressing plate 324 to move away from the fixed frame 1. When the movement reaches an appropriate distance, the person rotates the rotating plate 321 to make the rotating plate 321 rotate away from the connecting rod 6. The rotating plate 321 drives the auxiliary column 322 to rotate away from the connecting rod 6. The rotating plate 321 is a stainless steel plate, which has good wear resistance and large strength, and is not prone to breakage during use. At this time, the person can disassemble the fixed frame 1. Then, the person rotates the connecting block 315, and the connecting block 315 drives the connecting column 314 to rotate. The connecting column 314 drives the threaded rod 313 to move towards the connecting block 315. The threaded rod 313 drives the clamping block 312 to move away from the positioning groove 311 until the clamping block 312 slides out of the inner wall of the positioning groove 311. At this time, the person can directly move the two connecting frames 2 to make the connecting frames 2 move away from the connecting frame 4. The connecting frames 2 drive the four moving blocks 304 and the two limiting rods 303 to move away from the connecting frame 4. The limiting rod 303 can limit the moving block 304 to prevent the moving block 304 from being misaligned when sliding on the inner wall of the limiting groove 301. Then, the moving block 304 drives the positioning block 305 to move away from the connecting frame 4, and the positioning block 305 drives the guiding block 306 to move away from the connecting frame 4 until the guiding block 306 slides out of the inner wall of the connecting groove 317. At this time, the person can fold the square bracket composed of the two connecting frames 4 and the four connecting rods 5 and the square bracket composed of the two connecting frames 2 and the four connecting rods 6. When the person needs to fold the folding bracket into a T-shaped stage, the person can first take two display stands with the fixed frame 1 disassembled, and then move one of the moving blocks 304 inside the limiting groove 301 on the same side of one of the display stands to make the moving block 304 move to the middle position of the limiting groove 301. Then, the person rotates the rotating column 308 to make the rotating column 308 rotate towards the moving block 304. The anti-slip groove 309 provided on the arc surface of the rotating column 308 can increase the friction between the person's hand and the rotating column 308 and prevent the person from slipping when rotating the rotating column 308. Then, the rotating column 308 drives the protective pad 310 and the screw rod 307 to rotate towards the moving block 304.
