When the lifting frame 423 and the moving frame 413 are operated and moved, the two clamping blocks 56 are pressed to separate from the inside of the clamping slot block 54. When the staircase 2 is adjusted and installed at an angle, the staircase 2 is installed inside the two mounting blocks 53, so that the shaft 52 rotates inside the protrusion B51, so that the staircase 2 is placed stably. After the adjustment is completed, the clamping block 56 is released, and the spring 57 drives the clamping block 56 to be clamped inside the clamping slot block 54 to fix the shaft 52. When a weight is placed on the top of the staircase 2 for detection, the staircase 2 will not shake and fall off, which is safer. The hollow setting of the fixed frame 1, the moving frame 413 and the lifting frame 423 saves manufacturing materials.
