Detailed ways

The multi-functional ruler includes a substrate 1, a drawing disk 2, a linear ruler 9, and a paper cutter 12. The middle part of the substrate 1 is provided with a circular hollowed-out drawing disk 2 in the middle, and the ring edge of the drawing disk 2 is engraved with 0- The 360-degree scale is provided with a curved needle 4 and a straight needle 5 in the drawing disk 2, and one end of the curved needle 4 and the straight needle 5 with a fixed protrusion is respectively embedded in the annular fixing groove 3 of the drawing disk 2, and the other One end is hinged with the positioning center hole 7 of the drawing disk 2 through the positioning center needle 6. The position of the needle point of the positioning center needle 6 is slightly beyond the bottom plane of the substrate 1 by 2mm, and the positioning center hole 7 is used as a fixed point. The curved needle 4 and the straight needle 5 It can rotate around the fixed point in the ring-shaped fixed groove 3 of the drawing disk 2. On the straight needle 5, there are small holes 8 at intervals of 5mm. The two edges of the straight needle 5 are respectively provided with metric scales and inch scales for the convenience of users. Choose the appropriate radius according to your needs. Various types of curves and circles with different radii can be drawn by comprehensively utilizing the straight needle 5, the curved needle 4 and the straight ruler 9.

Both sides of the drawing disk 2 are respectively provided with longitudinal parallel tracks 11 , and the linear ruler 9 is embedded in the parallel tracks 11 provided with strip-shaped fixing grooves 10 through the fixing protrusions connected at both ends thereof. The fixed protrusions connected to the two ends of the linear ruler 9 can cooperate with the bar-shaped fixed grooves 10 in the parallel track 11 to realize the parallel sliding of the linear ruler 9 up and down in the parallel track 11. The upper and lower edges of the linear ruler 9 are respectively provided with Available in metric and inch scales, it can be used to draw the base of a triangle or the top and bottom of a trapezoid.

The top of the substrate 1 is provided with a strip track 13, the paper cutter 12 is embedded in the strip track 13 provided with a strip-shaped fixing groove 10 through the fixed protrusion 17 connected thereto, and the fixed protrusion 17 and the strip-shaped fixed groove 10 are mutually Cooperate, realize that paper cutting knife 12 slides on strip track 13. There is a "Z"-shaped spring piece 14 between the fixed protrusion 17 connected to the paper cutter 12 and the strip-shaped fixed groove 10. The upper end of the spring piece is connected to the two cards of the fixed protrusion, and the lower end is stuck in the fixed groove. , to control the expansion and contraction of the paper cutter 12.

The upper edge of the substrate 1 is engraved with a metric scale, which can be used as a metric ruler; the lower edge is engraved with an inch scale, which can be used as an inch ruler; the right edge is engraved with wavy patterns, which can be used to draw wavy lines.
