Abstract
The utility model discloses a ruler with a circle drawing function. The ruler comprises a ruler body, wherein scale marks are arranged on the upper side of the front side of the ruler body, a datum hole is formed in the position corresponding to the zero graduation in the middle part on the left end of the ruler body, a sleeve pipe is arranged above the datum hole, a datum rod is arranged in the sleeve pipe, a conic positioning head is arranged on the lower end of the datum rod, a rectangular through hole is arranged on the ruler body on the right side of the datum hole, a transparent sliding block is sleeved outside the middle part of the ruler body, a positioning screw is arranged in the lower part of the upper end face of the sliding block, and positioning holes which are matched with the through hole for use are formed in the middle parts of the upper end face and the lower end face of the sliding block. The ruler has the outstanding advantages that the structure is simple, the use is convenient, when circle drawing is needed, a lower end tip of the positioning head aims at the center of a circle, then the sliding block is adjusted towards the right side to an appropriate position, the positioning screw is used for fixing, a pen tip penetrates through the positioning hole to be contacted onto paper or a blackboard for drawing, so that the ruler has two functions of circle drawing and straight line drawing, and the placement and the carry of the ruler are facilitated.
Description
Technical field:
The utility model relates to drawing tools, particularly a kind of ruler that has picture circle function concurrently.
