The limit blocks 12 are fixedly connected to the connecting rod 9. By setting the angle measuring mechanism, when it is necessary to measure the angle, the limit seat 7 and the ruler 3 are separated from the cavity 2 and rotated around the rotating shaft 4 as the center of the circle by moving the handle 14. Since the center of the circle of the rotating shaft 4 and the center of the circle of the angle ruler 5 coincide with each other, the limit grooves 11 and the limit blocks 12 cooperate to make the connecting rod 9 slide inside the first moving groove 8 and the second moving groove 10 at the same time. After the ruler 3 is moved to the preset position, the angle data is obtained by observing the position of the connecting rod 9 and the scale on the angle ruler 5, so that the staff does not need to replace the angle ruler 5 for measurement when measuring the angle;

[0037] Reference Figure 1-8The measuring hole mechanism includes an adsorption seat 6 and a limiting seat 7. The adsorption seat 6 is fixedly installed at the bottom of the inner wall of the cavity 2, and the limiting seat 7 is fixedly installed on the left side of the measuring ruler 3. The material of the adsorption seat 6 is composed of a magnet, and the material of the limiting seat 7 is composed of a magnetic material. A meshing tooth 13 is fixedly installed on the surface of the rotating shaft 4, and a handle 14 is fixedly installed on the left side of the limiting seat 7. The handle 14 penetrates to the left side of the ruler body 1. An accommodating cavity 15 is provided inside the ruler body 1. A wedge 16 is slidably installed inside the accommodating cavity 15. The right side of the wedge 16 is set in an arc shape. A spring 17 is fixedly installed on the left side of the inner wall of the accommodating cavity 15. The other end of the spring 17 is fixedly connected to the left side of the wedge 16. A sliding groove 18 is provided on the rear side of the ruler body 1.

The rear side of the sliding rod 19 is fixedly installed with an elastic Buckle 20, by setting the hole measuring mechanism, when encountering a smaller hole and the ruler body 1 cannot be inserted, the ruler 3 is rotated by the handle 14 to rotate the ruler 3 180 degrees to align horizontally with the ruler body 1. During rotation, the arc-shaped setting of the wedge block 16 drives the meshing teeth 13 to rotate, which squeezes the wedge block 16 and retracts it into the accommodating cavity 15. When the meshing teeth 13 are not in contact with the wedge block 16, the wedge block 16 is ejected by the rebound force of the spring 17, and this is repeated until the ruler 3 is horizontally aligned with the ruler body 1, and the wedge block 16 is stuck in the gap between the meshing teeth 13, so that the ruler 3 is limited, and the ruler 3 is inserted into the hole.

[0038] Specifically, the working process or working principle of the design ruler for construction engineering is as follows: when in use, when it is necessary to measure the angle, the handle 14 is moved to make the limit seat 7 and the ruler 3 separate from the cavity 2 and rotate with the rotating shaft 4 as the center. Since the center of the rotating shaft 4 and the center of the angle ruler 5 coincide with each other, the limit groove 11 and the limit block 12 cooperate to make the connecting rod 9 slide inside the first moving groove 8 and the second moving groove 10 at the same time. After the ruler 3 is moved to the preset position, the angle data is obtained by observing the position of the connecting rod 9 and the scale on the angle ruler 5. When encountering a smaller hole where the ruler body 1 cannot be inserted, the ruler 3 is rotated by the handle 14. , so that the ruler 3 is rotated 180 degrees to be horizontally aligned with the ruler body 1. During the rotation, the rotating shaft 4 drives the meshing teeth 13 to rotate through the arc-shaped setting of the wedge block 16, which squeezes the wedge block 16 and retracts it into the accommodating cavity 15. When the meshing teeth 13 are not in contact with the wedge block 16, the wedge block 16 is ejected by the rebound force of the spring 17. This is repeated until the ruler 3 is horizontally aligned with the ruler body 1, and the wedge block 16 is stuck in the gap between the meshing teeth 13, so that the ruler 3 is limited. The ruler 3 is extended into the hole. By observing the scale on the ruler 3 and the length of the limit seat 7 and the handle 14, the data of the hole depth can be obtained.
