Stepladder Having Tipping Prevention Function
A stepladder includes two frames pivotally connected with each other, two pairs of support levers pivotally connected with the two frames, and two pairs of links pivotally connected with the two frames and pivotally connected with the support levers. Each of the two frames is provided with a side bar which has a first end formed with a connecting portion and a second end formed with a working portion. The working portion of the side bar is provided with a hook. Thus, each of the support levers is expanded and placed on the ground, and each of the links is connected between each of the support levers and each of the two frames in an inclined manner, so that the two frames are supported so as to prevent the stepladder from tipping or falling down.
