AI Technical Summary
Technical Problem
When drawing parallel lines with existing set squares, the locking mechanism of the auxiliary drawing component is prone to wear on the main body of the ruler, affecting its appearance and potentially causing wear on the scale.
Method used
Design a triangular ruler with a positioning slider. The slider is locked by inclined plane guidance or driving block clamping to avoid direct force on the ruler body and increase the force-bearing area to reduce wear.
Benefits of technology
It effectively reduces wear and tear on the set square when drawing parallel lines, protects the outer surface and scale of the ruler body, and maintains its aesthetics and accuracy.

Abstract
This application discloses an improved set square with a positioning slider, comprising a ruler body and a slider. The ruler body has a groove in which the slider slides. The slider has a through hole for inserting or mounting a pen for drawing. The slider includes an upper connecting block and a lower connecting block fixedly connected to each other. The sidewall of the groove that mates with the slider is an inclined surface. The upper or lower connecting block has an abutment portion that mates with the inclined surface. By longitudinally moving the slider, the abutment portion is guided and pressed or released against the inclined surface. Locking is achieved without using a driving block and by pressing with the inclined surface; stress is concentrated on the sidewall of the groove, without affecting the outer surface of the ruler body.
