A curved convex mirror 10 is fixedly connected to one side of the mirror frame 9. Several winding devices 12 are fixedly connected to the top of the outer wall of the guide sleeve 2. A traction steel rope 13 is wound and fixedly connected in the winding shaft of the several winding devices 12. A fixing steel rod 14 is fixedly connected to the bottom end of the traction steel rope 13.
[0025] As an optional technical solution of this utility model, each of the several winding devices 12 includes a fixed frame 121.

[0029] A type of road bend mirror used in municipal engineering works on the following principle:
[0030] 1) By rotating the adjusting screw 3, the adjusting screw 4 can be raised or lowered. At the same time, by rotating the second worm 19, the rotating shaft 7 can be rotated. Then, the first worm 21 drives the first transmission worm wheel 17 to rotate, which in turn drives the second connecting frame 16 to rotate through the transmission shaft 15. This causes the mirror frame 9 and the curved convex mirror 10 to rotate up and down. The rotating shaft 7 can rotate the convex mirror 10 horizontally. The height can be adjusted by raising or lowering the adjusting screw 4, thus achieving the adjustment of the height and the horizontal angle.
[0031] 2) Drive the fixing steel rods 14 at the bottom of several traction steel ropes 13 into the bottom surface around them;
[0032] 3) By using several winding devices 12 to wind and unwind the traction steel rope 13, the guide sleeve 2 is tightened from all sides, thereby tightening and fixing the guide sleeve 2, preventing swaying, and improving the stability of the fixation.
[0033] In summary, this municipal engineering curved mirror utilizes several winding devices 12 to wind and unwind the traction steel ropes 13. Simultaneously, the fixing steel pins 14 at the bottom of the traction steel ropes 13 are driven into the surrounding bottom surface, thereby tightening the guide sleeves 2 from all sides, achieving tension and fixation of the guide sleeves 2, preventing swaying, and improving the stability of the fixation. Furthermore, the traction steel ropes 13 can be completely retracted during storage, reducing volume and facilitating storage and transportation. Rotating the adjusting screw cylinder 3 drives the adjusting screw 4 to rise and fall. Simultaneously, rotating the second worm gear 19 drives the rotating shaft 7 to rotate, which in turn drives the first transmission worm wheel 17 to rotate via the first worm gear 21. This, in turn, drives the second connecting frame 16 to rotate via the transmission shaft 15, thereby causing the mirror frame 9 and the curved convex mirror 10 to rotate vertically. Rotating the rotating shaft 7 allows the convex mirror 10 to rotate horizontally. Adjusting the height via the adjusting screw 4 allows for height adjustment, thus achieving adjustment of both the height and horizontal angle, improving practicality.
