A plurality of pedals 2 are rotatably connected between the two fixing rods 1. The footrest 2 includes a front end surface 21 and an upper end surface 22. Circular slots 13 are formed in the opposite ends of the two fixing rods 1, and circular rods 23 embedded into the circular slots 13 are fixedly connected to the opposite ends of the pedal 2.

As shown in fig. 1 and 2, a plurality of foot pedals 2 are each connected to a fixing lever 1 through a locking mechanism 3. One end of the pedal 2 facing the fixed rod 1 is provided with a clamping groove 24. The locking mechanism 3 includes a latch 31 and a spring 32 disposed in the card slot 24. The end of the latch 31 away from the spring 32 is opened with an arc surface 311. Two opposite ends of the spring 32 are fixedly connected with one end of the locking groove 24 away from the opening and the locking block 31, respectively, and one end of the fixing rod 1 facing the pedal 2 is provided with a first insertion hole 33 and a second insertion hole 34 for inserting the locking block 31. When the front end surface 21 is perpendicular to the length direction of the fixing rod 1, the fixture block 31 is embedded into the first insertion hole 33; when the upper end surface 22 is perpendicular to the length direction of the fixing lever 1, the latch 31 is inserted into the second insertion hole 34.

As shown in fig. 1 and 2, one end of the fixing rod 1 facing the pedal 2 is opened with an arc-shaped slot 14 communicating the first insertion hole 33 and the second insertion hole 34, and the axis of the arc-shaped slot 14 is the same as the axis of the circular slot 13. The arc-shaped groove 14 is arranged to limit the fixture block 31, so that the fixture block 31 can only move in the fixture block 31, and the fixture block 31 is prevented from being separated from the arc-shaped groove 14.

As shown in fig. 1 and 3, a supporting plate 15 is fixedly connected to the lower end surface of the fixing rod 1, so that the contact area between the ladder stand and the ground is increased, and the bearing capacity and stability of the ladder stand are improved.

As shown in fig. 1 and 3, a plurality of supporting blocks 16 are fixedly connected to opposite ends of the two fixing rods 1, the supporting blocks 16 are disposed below the pedal plate 2, and the supporting blocks 16 are spaced from the pedal plate 2. When the upper end surface 22 is perpendicular to the length direction of the fixing rod 1, the lower end surface of the pedal 2 abuts against the upper end surface 22 of the supporting block 16. The supporting block 16 is arranged to further support the pedal 2, so that the strength of the pedal 2 is increased, and the safety of workers in climbing is improved.

As shown in fig. 1 and 3, the opposite ends of the two fixing rods 1 are both provided with handrails 4. The armrest 4 comprises a movable rod 41, one end of the movable rod 41 facing the fixed rod 1 is rotatably connected with a plurality of operating rods 42, and one side of each operating rod 42, which is far away from one end of the movable rod 41 and is far away from the joint of the fixed rod 1 and the operating rod 42, is rotatably connected with the fixed rod 1.
