The clamping piece is in a shape like a Chinese character 'men', and an opening end of the clamping piece is connected with the fulcrum bar. The ruler is provided with teeth which can display distances, and the ruler is provided with a safe area and a dangerous area. In the process of design, effectiveness of an actual effect is considered, and convenience, rationality and safety of an operation are considered.
