It is used to protect the edge of upper anchor plate to prevent construction tools from falling from the outer edge of upper anchor plate, thereby improving construction efficiency and construction safety. The edge protection part 4 includes a plurality of rotating rods 41 mounted on the safety protection frame 1, and a through groove is provided in the middle of the rotating rods 41. The rotating rods 41 are rotatably mounted on the safety protection frame 1, and the through groove is used to avoid impacting the anchor post on the upper anchor plate. The edge protection section 4 also includes a storage cylinder 42 and a safety net 43 disposed at the end of the rotating rod 41. The rotating rod 41 is provided with a limiting member 44 and a snap-fit ​​member 45 for limiting the safety net 43. The rotating rod 41 is used to support the storage cylinder 42. A notch is opened on the storage cylinder 42 for the safety net 43 to be moved out of the storage cylinder 42. The safety net 43 is rolled up in the storage cylinder 42 for storage. The limiting member 44 and the snap-fit ​​member 45 are used to limit the safety net 43 from being rolled up on the storage cylinder 42. The safety nets 43 between adjacent safety protection frames 1 are arranged in a ring shape and are arranged around the upper anchor plate. The edge protection section 4 also includes a rotating roller 46 disposed inside the storage cylinder 42 for winding up the safety net 43 and a hanging ring 47 disposed on the outer wall of the storage cylinder 42. The rotating roller 46 is used to wind up the safety net 43 to prevent the safety net 43 from being placed haphazardly, and the hanging ring 47 is used to hook onto the hook of the safety net 43 in another storage cylinder 42 to unfold the safety net 43. The safety net 43 is equipped with hooks for attaching hanging rings 47; The bottom of the rotating rod 41 is provided with a support block, which is used to make the rotating rod 41 and the safety net 43 inclined on the upper anchor plate, so as to raise the outer edge of the safety net 43 and prevent the construction tools from falling. Safety net 43 is fan-shaped; Multiple storage tubes 42 contain safety nets 43 that are spliced ​​together to form a circular safety net, which is used to provide comprehensive protection for the outer edge of the upper anchor plate; The limiting member 44 includes a toothed locking post 441 disposed at the end of the rotating roller 46 and a locking seat 442 disposed on the rotating rod 41. The rotating rod 41 is used to support the rotating roller 46, the rotating roller 46 rotates within the rotating rod 41, and the rotating rod 41 is used to support the locking seat 442.

The snap-fit ​​rod 443 engages with the toothed snap pin 441 on the rotating roller 46 to prevent the rotating roller 46 from rotating on its own. The limiting member 44 also includes a fixing rod disposed on the locking rod 443, the fixing rod being used to support the locking member 45 and to keep the locking rod 443 away from the toothed locking post 441; The snap-fit ​​component 45 includes a fixed seat 451 mounted on the rotating rod 41 and a movable rod 453 movably mounted within the fixed seat 451. The fixed seat 451 is provided with a second spring 452 for pushing the movable rod 453. Under the action of the second spring 452, the movable rod 453 slides within the fixed seat 451. When the rotating roller 46 needs to rotate, the snap-fit ​​rod 443 rotates within the snap-fit ​​seat 442, moving away from the toothed snap post 441 and pushing the movable rod 453 to compress the second spring 452. The fixed rod on the snap-fit ​​rod 443 is reset by the movable rod 453 under the action of the second spring 452. The movable rod 453 supports the fixed rod, causing the snap-fit ​​rod 443 to move away from the toothed snap post 441, thereby rotating the rotating roller 46 and retracting the safety net 43.

[0015] In use, firstly, when the safety net 43 is being retracted and extended on the storage cylinder 42 and the rotating roller 46, the movable rod 453 is pushed to compress the second spring 452, causing the movable rod 453 to move away from the locking rod 443. Then, the locking rod 443 on the locking seat 442 is rotated, and the fixed rod on the locking rod 443 passes through the movable rod 453. Then, the second spring 452 on the movable rod 453 pushes the movable rod 453 to reset. Under the pull of the first spring 444, the locking rod 443 drives the fixed rod to support the movable rod 453. The locking rod 443 moves away from the toothed locking post 441, and the rotating roller 46 retracts and extends the safety net 43. The hook on the safety net 43 is hooked onto the hanging ring 47 on another storage cylinder 42, unfolding the safety net 43. Then, the rotating rod 41 rotates on the vertical rod 11, laying the safety net 43 at the edge of the upper anchor plate.
