It can reduce the stress of the front-rear hinge shaft.

[0011] As preferred, the lower end surface of the inclined beam is provided with a plurality of gripping teeth. It can improve the braking effect of the step ladder.

[0012] As preferred, the guardrail is arranged on the side of the support frame away from the hinge shaft during use, the deck surface comprises a fixed deck plate and a movable deck plate, the fixed deck plate is fixed on the side of the support frame provided with the guardrail, and the movable deck plate is arranged on the surface of the side of the support frame away from the guardrail and overlaps the fixed deck plate. During use, the movable deck plate is moved to abut the guardrail pouring mold, so as to avoid the existence of a large gap between the utility model and the guardrail mold, which is unsafe. The side close to the guardrail pouring mold is not provided with a guardrail, so that the operation is convenient.

[0013] As preferred, the end of the movable deck plate away from the pull rod is provided with an upward blocking edge towards the upper surface of the movable deck plate, and the side surface of the upper blocking edge away from the guardrail is provided with a plurality of rubber isolation blocks. When the movable deck plate is close to the guardrail mold, the movable deck plate is moved by pushing the blocking edge; when the movable deck plate is away from the guardrail mold, the upper blocking edge is pulled by the hooking of the blocking edge away from the pull rod. The existence of the rubber isolation blocks can ensure that there is a gap between the blocking edge and the guardrail mold for the hooking of the hook. The force is convenient when the movable deck plate is moved.

[0014] Beneficial effects: it can be used as an operation platform, so that the user can conveniently stand on the utility model to pour concrete into the guardrail mold; it is labor-saving to move; and it can be reliably stopped when not moving. BRIEF DESCRIPTION OF DRAWINGS
