DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-4 The movable ladder 2 is movably inserted into the inner side of the main ladder 1, and the movable ladder 2 movably penetrates the main ladder 1 and extends to the outside, and a hook 3 is fixedly arranged on the outer side of the movable ladder 2 at the outer part of the main ladder 1, and two groups of mounting grooves 4 are opened on the lower side of the hook 3. Limiting blocks 5 are movably arranged on the inner sides of the two groups of mounting grooves 4. An arc clamping plate 6 is fixedly arranged on the outer side of the limiting block 5, and the arc clamping plate 6 movably penetrates the mounting groove 4 and extends to the lower side, and two groups of limiting springs 7 are arranged on the inner side of the mounting groove 4. One end of the two groups of limiting springs 7 is respectively connected to the two sides of the mounting groove 4, and the other end of the limiting spring 7 is connected to the limiting block 5. A movable seat 8 is movably arranged on the outer side of the main ladder 1, and a mounting rod 9 is rotatably arranged on the upper side of the movable seat 8. A tool frame 10 is fixedly arranged on the outer end of the mounting rod 9, and the arc clamping plate 6 can be convenient for clamping the steel frame. At the same time, after use, only the hanging ladder needs to be pushed upward, so that the arc clamping plate 6 can be quickly separated from the steel frame, thereby facilitating the removal of the hanging ladder.

[0022] Among them, the mounting rod 9 movably passes through the movable seat 8 and extends to the lower side, and the outer side of the mounting rod 9 is located at the lower side of the movable seat 8. A threaded surface 11 is provided, and a butterfly nut 12 is threadedly sleeved on the outer side of the threaded surface 11. By loosening the butterfly nut 12 downward, the mounting rod 9 can be rotated to drive the tool frame 10 to rotate, thereby facilitating the adjustment of the angle of the tool frame 10 and improving the flexibility of use of the tool frame 10.

[0023] Among them, a T-shaped slider 13 is fixedly arranged on the outside of the movable seat 8, and a T-shaped groove 14 for docking with the T-shaped slider 13 is opened on the inside of the main ladder 1. The T-shaped slider 13 slides within the T-shaped groove 14 to facilitate the height adjustment of the tool frame 10 to meet various usage requirements.

[0024] Among them, an L-shaped block 15 is fixedly provided on the outside of the T-shaped slider 13, a positioning rod 16 is movably provided on the outside of the L-shaped block 15, a fixing head 17 is fixedly provided on the outer end of the positioning rod 16, and the other end of the positioning rod 16 movably passes through the L-shaped block 15 and extends to the inside. A plurality of groups of positioning holes 18 for docking with the positioning rod 16 are provided on the outside of the main ladder 1. By inserting the positioning rod 16 into the internal position control 18, the movable seat 8 can be conveniently fixed, thereby facilitating the fixation of the tool frame 10.

[0025] Among them, a return spring 19 is sleeved on the outside of the positioning rod 16, one end of the return spring 19 is connected to the L-shaped block 15, and the other end of the return spring 19 is connected to the fixed head 17. The return spring 19 is initially in a contracted state, so that when the fixed head 17 is loosened, the elasticity of the return spring 19 can drive the positioning rod 16 to be firmly inserted into the positioning hole 18, thereby ensuring the stability of the tool frame 10.

[0026] Among them, two groups of positioning bolts 20 are set through the outer thread of the main ladder 1, and multiple groups of positioning screw holes 21 for docking with the positioning bolts 20 are opened on the outer side of the movable ladder 2. By setting the positioning bolts 20 and the positioning screw holes 21, the height of the movable ladder 2 can be easily adjusted and fixed.

[0027] Among them, handles 22 are fixedly provided on both sides of the main ladder 1, and rubber sleeves are fixedly provided on the outer sides of the two sets of handles 22. The rubber sleeves can increase the friction, thereby facilitating the grabbing of the handles 22 and moving the hanging ladder.

[0028] When the staff member climbs up the ladder, the hanging ladder can be driven downward by gravity, and the steel frame pushes the curved clamping plate 6 to move and compress the limit spring 7. The elasticity of the limit spring 7 can drive the two sets of curved clamping plates 6 to clamp the steel frame, thereby ensuring the stability of the ladder when in use. When the staff member is working on the ladder, the tool can be placed in the tool frame 10, and at the same time, the positioning rod 16 is driven to move by pulling the fixed head 17 outward, so that the positioning rod 16 is moved out of the positioning hole 18, and then the L-shaped block 15 is moved to drive the T-shaped slider 13 to slide in the T-shaped slide groove 14. When the T-shaped slider 13 moves, it drives the movable seat 8 and the mounting rod 9 to move, so that the height of the tool frame 10 can be adjusted. In addition, by loosening the butterfly nut 12 downward, the mounting rod 9 and the tool frame 10 can be rotated, so that the angle of the tool frame 10 can be adjusted to meet various usage requirements.
