The second slide groove portion 122 is located above the first slide groove portion 121. Preferably, the second slide groove portion 122 can cooperate with the limiting joint 13 (described below) to play a good limiting role on the first ladder frame 20.

[0039] According to an embodiment of the present invention, the first support rod 21 is configured to extend the ladder mechanism out of the frame 10 when at the end of the first slide groove portion 121 , and to retract the ladder mechanism into the frame 10 when at the end of the second slide groove portion 122 .

[0040] Preferably, in the process of the first support rod 21 moving from the second slide groove portion 122 to the first slide groove portion 121, the first ladder frame 20 can move downward under the action of gravity and gradually extend out of the skeleton 10, and when the first support rod 21 moves to the end of the first slide groove portion 121, the first ladder frame 20 will be in a fully expanded state.

[0041] Preferably, in the process of the first support rod 21 moving from the first slide groove part 121 to the second slide groove part 122, the first ladder frame 20 can move upward and gradually shrink into the frame 10 under the push of external force, and when the first support rod 21 moves to the end of the second slide groove part 122, the first ladder frame 20 will be in a hidden state.

[0042] According to the utility model, if Figure 2 and 4 As shown, the ladder climbing tool 100 further includes slide plates 11 symmetrically arranged on both sides of the frame 10. Preferably, the slide grooves 12 are radially arranged on the slide plates 11. Since the slide plates 11 can be firmly mounted on the frame 10, the first ladder frame 20 can also stably slide in the slide grooves 12 through the first support rods 21, thereby improving the stability and firmness of the ladder climbing tool 100.

[0043] In one embodiment, Figure 1As shown, the first ladder frame 20 includes two first support rods 22 arranged at intervals, and a first fixing rod 23, a first pedal 24 and a cross tube 25 arranged in sequence between the two first support rods 22.

[0050] In one embodiment, the limit joint 13 further includes through holes 132 disposed on both sides of the oblique groove 131. Preferably, the limit joint 13 is fixed to the frame 10 by at least two pins extending through the through holes 132. In this way, the limit joint 13 can be more firmly installed on the frame 10, thereby improving the safety and stability of the ladder climbing tool 100 during use.

[0051] According to the utility model, if Figure 1 As shown, the ladder mechanism further includes a second ladder frame 30 disposed below the first ladder frame 20. Preferably, the second ladder frame 30 is configured as an H-shaped structure and includes two second support rods 31 arranged at intervals and a connecting rod 32 disposed between the two second support rods 31.
