Positioning holes 11 are provided on both sides of the surface of the indicator sign 10. The positioning holes 11 are used in conjunction with the limiting mechanism 13, under the action of which, the indicator sign 10 can be limited to prevent its rotation from causing the guide device to be unable to effectively guide the driver safely. A rotating rod 15 is fixedly connected to the center point of the surface of one side of the indicator sign 10, and its position will not shift when the direction of the indicator sign 10 is changed.

[0025] The folding mechanism 3 includes a rotating shell 31, and the number of the rotating shells 31 is two. The inner wall of the rotating shell 31 is rotatably connected to the inner wall of the connecting rod 2. One side of the surface of the rotating shell 31 is fixedly connected to a storage shell 32. The surface of the storage shell 32 is slidably connected to the inner wall of the sliding shell 4. One side of the inner wall of the storage shell 32 is rotatably connected to a rotating shaft 34. The surface of the rotating shaft 34 is rotatably connected to a fixed rod 33. One end of the fixed rod 33 is fixedly connected to one side of the surface of the rotating shell 31 on the other side. One side of the fixed rod 33 is located inside the rotating shell 31, and a sufficient gap is left between the top of the fixed rod 33 and the top of the inner wall of the rotating shell 31 to prevent To prevent the guiding device from being folded, the positioning groove 6 is located on one side of the surface of the storage shell 32 and the fixing rod 33. When the positioning column 5 and the positioning groove 6 are used in conjunction, the rotating shell 31 and the fixing rod 33 can be limited when the guiding device is unfolded and used, to prevent them from being retracted to a certain extent under the influence of external factors, thereby causing the supporting force of the guiding device to decrease. When folding, the rotating shells 31 on both sides respectively drive the rotating shells 31 and the fixing rod 33 to rotate, and the other end of the fixing rod 33 is folded toward the inside of the rotating shell 31 with the rotating shaft 34 as the center until it overlaps, so that the staff can reduce the area occupied by it during transportation.
[0026] The limiting mechanism 13 includes a mounting block 131, the surface of the mounting block 131 is fixedly connected to the inner wall of the connecting plate 16, a second spring 133 is fixedly connected to one side of the surface of the mounting block 131, and a positioning rod 132 is fixedly connected to the other end of the second spring 133, the other end of the positioning rod 132 passes through the mounting block 131 and extends to the inside of the positioning hole 11 and is slidably connected to the penetration, the positioning rod 132 is located inside the second spring 133, which can prevent the second spring 133 from having a large deviation, the portion of the positioning rod 132 extending to the inside of the positioning hole 11 conforms to the shape of the positioning hole 11, the surface of the positioning rod 132 is slidably connected to the inner wall of the positioning hole 11, which can effectively limit the sign 10, and the mounting block 131 has an internal opening. A rotating groove 14 is provided, and the rotating groove 14 is used in conjunction with a positioning rod 132. When the positioning rod 132 moves to a suitable position, the positioning rod 132 can be limited by rotating the mounting block 131. When the staff needs to change the guiding direction, it is necessary to release the limit on the sign 10 and pull the positioning rods 132 on both sides. The positioning rods 132 drive the second spring 133 to extend. When the positioning rod 132 moves to a suitable position, the limit on the sign 10 is released, and the positioning rod 132 is continued to be pulled to make it enter the rotating groove 14. The staff rotates the positioning rod 132 to make one end of it different from the entrance direction of the rotating groove 14, thereby limiting the positioning rod 132, which is convenient for the staff to change the guiding direction of the guiding device.
[0027] Working principle: when the staff unfolds and places the guiding device, during the unfolding process of the folding frame 1, the rotating shells 31 on both sides respectively drive the rotating shells 31 and the fixed rods 33 to rotate with the rotating shaft 34 as the center point until they are fully unfolded. The staff slides the sliding shell 4, and the sliding shell 4 drives the positioning column 5 to move. When the positioning column 5 moves to a certain position, it falls into the positioning groove 6 to limit it, effectively preventing the guiding device from being retracted under external factors. When it is necessary to change the guiding direction, the staff pulls the positioning rods 132 on both sides, and the positioning rods 132 drive the second spring 133 to extend. When the positioning rod 132 moves to the appropriate position, the limit on the indicator sign 10 is released, and the positioning rod 132 is continued to be pulled to make it enter the rotating groove 14. The staff The staff rotates the positioning rod 132 so that one end of it changes the direction of the entrance of the rotating groove 14, thereby limiting the positioning rod 132, pulling down the support frame 9, and the support frame 9 descends to drive the first spring 8 to compress. When it descends to a suitable position, the indicator sign 10 is rotated. When the indicator sign 10 is rotated to a suitable position, let go so that the first spring 8 drives the support frame 9 to return to its original position to assist in supporting the indicator sign 10. Subsequently, the positioning rod 132 is rotated in the same way. When the direction of one end of the positioning rod 132 is consistent with the direction of the entrance of the rotating groove 14, let go, and the second spring 133 returns to its original position, driving the positioning rod 132 to move out of the rotating groove 14, so that the positioning rod 132 enters the positioning hole 11, and continues to limit the indicator sign 10 to prevent it from easily changing the guiding direction during use.
