Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1-3, the scribing and measuring ruler applied to the surface of a metal workpiece structurally comprises a square ruler 1, wherein the square ruler 1 is composed of a vertical shaft arm and a horizontal shaft arm, a 90-degree protractor is arranged at the intersection of the vertical shaft arm and the horizontal shaft arm, scales are marked on the vertical shaft arm and the horizontal shaft arm, a movable measuring ruler 2 or a circular scribing ruler 8 is detachably installed on the vertical shaft arm and the horizontal shaft arm, the movable measuring ruler 2 comprises two sections which are respectively parallel to the vertical shaft arm and the horizontal shaft arm, scales are marked on each section of the movable measuring ruler 2, the fixed position between the movable measuring ruler 2 or the circular scribing ruler 8 and the square ruler 1 is adjusted, the measurement of a straight line, an oblique line, an arc line and an angle can be realized, and scribing can be completed along the edges of the movable measuring ruler 2, the circular scribing ruler 8 and the square ruler 1.

Activity dipperstick 2, circular marking off chi 8 and square 1 all process and have the U-shaped recess, and when activity dipperstick 2 or circular marking off chi 8 and square 1 were installed, it was crossing the U-shaped recess to adopt the bolt cooperation in nodical department. The bolt fit connection is realized by installing the fixing knob 3 and the nut 7 at the intersection point. The nut 7 is tightly attached in the U-shaped groove of the square 1.

The bottom surfaces of the end parts and the intersection parts of the vertical shaft arm and the horizontal shaft arm of the square 1 are respectively provided with an adjusting foot margin 5. The adjusting feet 5 are in threaded connection with the square 1. And a spring 6 is arranged at the threaded connection part of the adjusting foot margin 5 and the square 1.

The two sections of the active measuring scale 2 of the invention can be used separately or can be used simultaneously when being pieced together.

The specific working principle of the invention is as follows: the measuring scale can directly measure the size of a workpiece 4 and accordingly mark the workpiece 4, can measure straight lines, oblique lines, arc lines and angles according to different shapes of the workpiece 4 and different drawing requirements, can be freely matched and used on a vertical shaft and a horizontal shaft by utilizing the movable measuring scale 2 and the circular marking scale 8, measure various sizes and guide marking. Aiming at different thicknesses of the workpiece 4, the height of the measuring scale can be adjusted by adjusting the feet 5, so that the measuring scale and the workpiece 4 are equal in height, and the accuracy of measuring and scribing is improved. Simultaneously, installation spring 6 on adjustment lower margin 5 makes adjustment lower margin 5 and square 1 in close contact with, prevents the not hard up of adjustment lower margin 5, guarantees the equilibrium of dipperstick, improves the precision.
