Limiting device for reducing clamping stagnation of drawing ladder

A limiting device for reducing clamping stagnation of a drawing ladder comprises a sliding way and a folding ladder, drawing ladder guide rails are symmetrically arranged on the two sides of the sliding way, the folding ladder is arranged in the sliding way in a drawing mode, limiting devices are further arranged on the two sides of a ladder door baffle corresponding to the sliding way, and each limiting device comprises a vertically-arranged center shaft and a sleeve arranged on the center shaft in a sleeving mode. The central shafts are correspondingly and fixedly arranged on the two sides of the ladder door, and the sleeves are in sliding fit with the folding ladder. The position of the baffle is replaced through the sleeve and the round steel, the sleeve effectively reduces clamping stagnation when the drawing ladder is drawn, the sleeve is cylindrical, clamping stagnation can be reduced and left-right limiting can be achieved when the drawing ladder is drawn, and the two sides of the drawing ladder are e
