[0021] Example
[0022] like Figures 1-4 As shown, the movable connection structure is installed on the fixed shoulder strap. The movable connection structure includes: a pair of tension ropes, a pair of concave sleeve blocks 1, a pair of convex telescopic blocks 2, a pair of trapezoidal insert blocks 3, a pair of T-shaped insert rods 4, a pair of sleeve limit springs 5, multiple horizontal telescopic shafts 6, multiple telescopic sleeve springs 7, multiple telescopic concave wheels 8, multiple telescopic bearing blocks 9, and a pair of hook assemblies.
[0023] Specifically, a pair of tension ropes are installed on the fixed shoulder strap; a pair of concave sleeve blocks 1 are respectively connected to the pair of tension ropes; each pair of concave sleeve blocks 1 has a convex telescopic groove and a concave groove; a pair of convex telescopic blocks 2 are respectively movably inserted into the inner side of the pair of convex telescopic grooves; a pair of trapezoidal insert blocks 3 are respectively installed on the pair of convex telescopic blocks 2; each pair of concave grooves has a convex telescopic hole; a pair of T-shaped insert rods 4 are respectively movably inserted into the inner side of the pair of convex telescopic holes; and a pair of sleeve limiting springs... Springs 5 are respectively fitted onto a pair of T-shaped insert rods 4. Multiple horizontal bearing grooves are respectively opened on the inner side of a pair of concave sleeve blocks 1. Multiple telescopic bearing blocks 9 are respectively movably inserted into the inner side of multiple horizontal bearing grooves. Multiple horizontal telescopic shafts 6 are respectively inserted into the inner side of a pair of convex telescopic grooves and multiple horizontal bearing grooves. Multiple telescopic sleeve springs 7 are respectively fitted onto multiple horizontal telescopic shafts 6. Multiple telescopic concave wheels 8 are respectively installed on multiple telescopic bearing blocks 9. A pair of hook assemblies are installed on the fixed shoulder strap.
[0024] It should be noted that, in the above process, by extending and retracting the convex telescopic block 2 on the concave sleeve block 1 to the inside of the convex telescopic groove, and then fitting the concave sleeve block 1 onto the shielding and protective brackets on both sides of the climbing ladder, and by movably inserting the shielding and protective brackets into the inside of multiple telescopic concave wheels 8, the convex telescopic block 2 inside the concave sleeve block 1 is released, allowing the convex telescopic block 2 to stably extend and retract horizontally along the horizontal telescopic shaft 6. Simultaneously, the telescopic sleeve spring 7, which extends horizontally, drives the convex telescopic block 2 on it, causing the convex telescopic block 2 to stably extend and retract horizontally along the convex telescopic groove.
