[0011] The following further elaborates on the present utility model in conjunction with the accompanying drawings and specific embodiments:

[0012] As Figure 1 - Figure 2 shown, an adjustable triangular ruler for construction engineering includes a fixed bottom edge A1, a rotating hinge 2, a fixed bottom edge B3, a rotating vertical rod 4, an adjusting bolt 5, a sliding groove 6, a bearing 7, and a sliding support rod 8. The right bottom of the fixed bottom edge A1 is installed with the fixed bottom edge B3 through the rotating hinge 2. The left side of the top of the fixed bottom edge A1 is installed with the rotating vertical rod 4, and the bottom of the rotating vertical rod 4 is connected to the fixed bottom edge A1 through the adjusting bolt 5. A sliding groove 6 is opened at the top of the fixed bottom edge A1. The lower front end of the rotating vertical rod 4 is installed with the sliding support rod 8 through the bearing 7. The bottom of the sliding support rod 8 is installed in the sliding groove 6, and the bottom of the sliding support rod 8 can slide back and forth in the sliding groove 6. The adjustable triangular ruler for construction engineering further includes a rotating wire winding roller 9, a steel wire rope 10, a fixed nut 11, and a reserved screw hole 12. The top of the front end of the rotating vertical rod 4 is installed with the rotating wire winding roller 9. The steel wire rope 10 is wound and installed on the rotating wire winding roller 9.
