[0028] Working principle: If you need to use the ladder 1, you only need to rotate and open the connecting rod 241, and then pull the two sets of sliding rods 243 through the fixed rod 245 to slide in the two sets of sliding grooves 242 respectively, and the sliding rod 243 drives the limiting rod 253 to slide until the limiting rod 253 corresponds to the limiting hole 254, and the limiting rod 253 can be pushed out of the movable groove 251 by the restoring force of the spring 252, and inserted into the limiting hole 254 to lock the sliding rod 243, and then rotate and open the connecting rod 121, and pull the two sets of sliding rods 123 through the fixed rod 125 to slide in the two sets of sliding grooves 122 respectively, and the sliding rod 123 drives the limiting rod 133 Slide until the limit rod 33 corresponds to the limit hole 34, and the limit rod 33 can be pushed out of the movable groove 31 by the restorative force of the spring 32, and inserted into the limit hole 34 to lock the slide rod 23. At this time, the slide rod 23 will also drive the plug block 24 to be inserted into the slot 44. Finally, the handle 66 can be held and rotated, and the handle 66 drives the screw rod 63 to rotate in the nut 62. Through the rotation of the thread, the screw 63 drives the limit block 64 to move in the installation groove 61 until the limit block 64 is inserted into the limit groove 65. Then, the plug block 24 can be locked in the slot 44, making the ladder 1 more stable;
[0029] In addition, if the ladder 1 needs to be folded up, it is only necessary to hold the handle 66 and rotate it. The handle 66 drives the screw rod 63 to rotate in the opposite direction, and the screw rod 63 can drive the limit block 64 to move, and the limit block 64 can be pulled out of the limit groove 65 and moved into the installation groove 61. Then, the limit rod 1 33 and the limit rod 2 53 can be pressed respectively, so that the limit rod 1 33 and the limit rod 2 53 slide in the movable groove 1 31 and the movable groove 2 51 and compress the spring 1 32 and the spring 2 52. At this time, the slide bar 1 23 and the slide bar 2 43 are pushed until the slide bar 1 23 and the slide bar 2 43 are pushed into the slide groove 1 22 and the slide groove 2 42. At the same time, the insert block 24 can be pulled out of the slot 44. Finally, the connecting rod 1 21 and the connecting rod 2 41 can be rotated until the connecting rod 1 21 and the connecting rod 2 41 are rotated to be parallel to the ladder 1, and the device can be folded and folded up.
[0030] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
