The invention provides a ladder with a measuring caliper. A groove is formed in the ladder leg side end of the ladder, and is provided with the measuring caliper inside; and when users stand on the ladder for punching positioning at ordinary times, the measuring caliper can be used for accurate positioning to prevent the deviation caused by visual inspection.
本发明提供一种带测量卡尺的梯子,所述的梯子的梯腿侧端上设有一个凹槽,内置有测量卡尺,平时我们站在梯子上打孔定位时,可以用测量卡尺来准确定位,避免目测所带来的偏差。
