Examples

A novel angle ruler, refer to fig. 1-2, comprises a scale plate 1, a pointer ruler 2, a T-shaped ruler 3, a left clamping groove strip 4, a right clamping groove strip 5 and a locking screw 6, wherein the scale plate 1 comprises a sector plate 11 and a first rectangular plate 12 integrally arranged on one side of the sector plate 11, 0-90-degree scale marks are arranged on the sector plate 11, a first through hole 13 is arranged at an angle end, away from the 0-90-degree scale marks, of the sector plate 11, and distances from a center Z1 of the first through hole 13 to right-angle edges D1 and D2 of the sector plate are equal;

referring to fig. 3, the pointer ruler 2 includes a second rectangular plate 21 and a tip plate 22 integrally disposed on the left side of the second rectangular plate 21, the second rectangular plate 21 is provided with a second through hole 23 having the same size as the first through hole 13, and the distances from the second through hole 23 to the two sides C1 and C2 of the second rectangular plate are the same, and the pointer ruler 2 is rotatably disposed on the scale plate 1 by a pin 7 penetrating through the first through hole 13 and the second through hole 23;

referring to fig. 5, a left clamping groove strip 4 and a right clamping groove strip 5 with L-shaped cross sections are fixed on a first rectangular plate 21 through bolts, a T-shaped ruler 3 is slidably arranged in a sliding groove formed by the first rectangular plate 21, the left clamping groove strip 4 and the right clamping groove strip 5, and a through hole is formed in the side wall of the right clamping groove strip 5 and a locking screw 6 is installed;

referring to fig. 4, the T-square 3 includes a third rectangular plate 31 and a right-angled trapezoidal plate 32 integrally provided at a lower end of the third rectangular plate 31, and a distance from an acute vertex T of the right-angled trapezoidal plate 32 to a center Z1 of the first through hole 13 is equal to a distance from a center of the first through hole 13 to the right-angled sides D1, D2 of the sector plate, and is also equal to a distance from the second through hole 23 to two sides C1, C2 of the second rectangular plate.

In the initial state, side T2 of T-bar 3 coincides with side C2C2 of pointer bar 2, see fig. 1; when the angle needs to be measured, the locking screw 6 is firstly loosened to enable the edge T2 of the T-shaped ruler 3 to coincide with one edge of the object 8 to be measured, then when the pointer ruler 2 is rotated, the edge C2 of the pointer ruler 2 coincides with the other edge of the object 8 to be measured, then the locking screw 6 is screwed up to be fixed, the T-shaped ruler 3 is prevented from sliding, and the angle a of the object 8 to be measured can be directly indicated by the angle indicated by the tip end of the pointer ruler 2 (70 degrees), and the angle is shown in figure 6.

Similarly, when a specific angle needs to be drawn, the angle of the specific angle can be drawn only by loosening the locking screw, turning the pointer ruler 2 to a certain angle, for example, 70 degrees, then tightening the locking screw 6, and drawing lines along the side T2 of the T-shaped ruler 3 and the side C2 of the pointer ruler 2 respectively with a pencil.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
