Similarly, with the continuous rising of the bamboo ladder body, the fourth support rod 17 is drawn out from the sleeve 9 of the third support rod 16, and is fixed through the pin 28 on the fourth support rod, so that the whole inclined support rod can be automatically unfolded by analogy. And then the inclination angle of the diagonal brace is adjusted by rotation to drive the first folding rod 11 and the second folding rod 12 to rotate, so that the balance rod 7 is unfolded, when the balance rod 7 is completely unfolded, the first folding rod 11 and the second folding rod 12 form an angle of 180 degrees, and the limiting block 13 is used for preventing the first folding rod 11 and the second folding rod 12 from continuously rotating and opening, thereby completing the positioning between the first folding rod 11 and the second folding rod 12.

The operating principle of the adsorption device 66 is as follows: when the bamboo ladder body leans against the wall surface for use, the adsorption device 66 is perpendicular to the supporting surface, the supporting block 37 and the adsorption device 66 form a certain angle, and the arc-shaped inclined surface 38 abuts against the top end of the adsorption device 66, so that the supporting block 37 is in contact with the adsorption device 66, and the supporting block 37 is prevented from continuously rotating. Then, the rotating ring 63 is rotated, the rotating ring 63 can drive the rotating rod 64 fixedly connected with the rotating ring to rotate in the fan-shaped sliding groove 65, the convex block 59 of the upper shell 55 slides in the annular sliding groove, so that the rotation of the upper shell 55 is realized, the rotation of the upper shell 55 can drive the knob 61 to rotate due to the interference fit between the upper shell 55 and the knob 61, and the rotation of the knob 61 can change the adsorption state of the sucker body 62. When the bamboo joint ladder body is fixed to needs, the rotatory change ring 63 accomplishes the absorption operation promptly, and the rotatory sucking disc 54 is firm adsorbs on the plane to promote the stability between bamboo joint ladder body and each holding surface, avoid the bamboo joint ladder body landing of leaning on to one side, reduce the potential safety hazard, and operation process convenient and fast, labour saving and time saving. When the bamboo joint ladder body needs to be removed, the rotating ring 63 is rotated in the opposite direction to release the rotating sucker 54, so that the suction force on the rotating sucker 54 disappears, and the same convenient and fast adsorption device 66 for picking up the bamboo joint ladder body can generate adsorption force on the supporting surface.

When the adsorption device 66 needs to be disassembled, the nuts at the two ends of the connecting rod 47 are firstly screwed off, then the connecting rod 47 is pulled out, and the sliding block 44 can drive the shaft rod 43 to move out of the rotating hole 42, so that the whole adsorption device 66 is disassembled. Similarly, when the adsorption device 66 needs to be installed, the slider 44 is moved, and when the slider 44 is contacted with the supporting block 37 and cannot move, the first through hole corresponds to the second through hole 46, and then the connecting rod 47 is inserted into the through holes and nuts are screwed at two ends of the connecting rod.

When the rotary suction cup 54 needs to be replaced, a finger or a hard object is inserted into the fourth through hole 60, the fifth through hole 49 and the sixth through hole 48, and the rotary suction cup 54 is pushed out of the housing 19.
