The surface of block a7 is arranged as an inclined plane. After pressing block a7 to the top plane for retraction, the pull rod 5 can be pulled upward to make the inner wall of the columnar block 4 squeeze the inclined surface of block a7 to retract it, and at the same time move upward until block a7 is completely retracted. At this time, block a7 is pressed against the inner wall of the columnar block 4 and cannot be unfolded under the action of the reset spring a6. The outer wall of block a7 is fixedly connected to the inner wall of the columnar block 4. At this time, the columnar block 4 can be removed together with the bridge frame body 3, and the bottom end of block a7 contacts the outer wall above the mounting frame 1. A vent 14 is provided at the bottom end of the bridge frame body 3 to promote air circulation inside the bridge frame and prevent the corrosion of the bridge frame structure by accumulated water and moisture. At the same time, it also helps to dissipate heat and avoid overheating of the bridge frame. It can also reduce wind resistance and improve the stability and safety of the bridge frame.

[0031] Reference Figure 1 and Figure 2 The inner wall of the left end of the bridge body 3 is fixedly connected to the plug plate 8, and a slot 12 is provided on the inner wall of the right end of the bridge body 3. The outer wall of the plug plate 8 is plugged into the inner wall of the slot 12. The inner wall of the plug plate 8 is elastically connected with a card block b10 through a return spring b9. One end of the return spring b9 is fixedly connected to the inner wall of the plug plate 8, and the other end of the return spring b9 is fixedly connected to the inner end of the card block b10. The outer surface of the card block b10 is set as an inclined surface. In the process of inserting the plug plate 8 into the slot 12, the inner wall of the slot 12 squeezes the inclined surface of the card block b10 to squeeze the return spring b9 and retract it. At the same time, the elastic force generated by the deformation of the return spring b9 gives the card block b10 an outward thrust, prompting it to reset. A card slot 15 is provided on the inner wall of the body 3. When the plug plate 8 is fully inserted into the slot 12, the card block b10 is inserted into the card slot 15 under the action of the reset spring b9, and the outer wall of the card block b10 is engaged with the inner wall of the card slot 15. A sleeve 13 is fixedly connected to the right end of the bridge frame body 3. The sleeve 13 protects the connection between the plug plates 8 and the slots 12 of the two groups of bridge frame bodies 3 to increase the stability of the connection. A pressing plate 11 is slidably connected to the inner wall of the sleeve 13. The inner end of the pressing plate 11 contacts the outer wall of the card block b10. Pressing the pressing plate 11 inward can press the card block b10 out of the card slot 15. At this time, the two groups of bridge frame bodies 3 can be detached, and the rectangular groove 2 leaves a certain sliding space.

[0032] Working principle: Insert the top column block 4 of the bridge frame main body 3 into the rectangular groove 2 of the mounting frame 1. During this process, the inner wall of the rectangular groove 2 squeezes the inclined surface of the block a7 to retract it until it is fully inserted into the rectangular groove 2. The block a7 pops out of the outer wall above the column mounting frame 1 under the action of the reset spring a6. When it needs to be removed, press the block a7 inward and then pull the pull rod 5 upward until the block a7 is completely retracted and stuck on the inner wall of the column block 4. At this time, the bridge frame main body 3 can be removed from the mounting frame 1. During the installation process, the bridge frame main bodies 3 need to be spliced ​​together in pairs and the plug-in plate 8 is inserted into the slot 12. During this process, the inclined surface of the block b10 is squeezed and retracted by the inner wall of the slot 12 until it is aligned with the slot 15, and the reset spring b9 pushes it into the slot 15 to fix it. When it needs to be disassembled, press the pressing plate 11 inward to push the block b10 out of the slot 15, and then slide the bridge frame main body 3 outward, leaving a certain sliding space in the rectangular groove 2.
