[0030] like Figure 1-4 As shown, the embodiment of the present application provides a point marking device for field line setting, which includes a support rod 1, a first reflector 2, a linkage mechanism 3 and a movable reflector mechanism 4. Among them, the support rod 1 has a preset length; the first reflector 2 is arranged at one end of the support rod 1 along the length direction; the linkage mechanism 3 includes a linkage frame 31 and a limit rod 32, the linkage frame 31 is movably arranged on a side of the support rod 1 close to the first reflector 2, the linkage frame 31 can rotate relative to the support rod 1, the limit rod 32 is sleeved on the outer wall of the support rod 1 and located in the linkage frame 31, and a slide groove 33 is arranged around the side wall of the limit rod 32; the number of the movable reflector mechanism 4 is multiple, the movable reflector mechanism 4 includes a second reflector 41 and a transmission mechanism, the transmission mechanism can drive the second reflector 41 to move along the slide groove 33, and the movement of the second reflector 41 includes rotation and revolution with the limit rod 32 as the center.

[0031] The point marking device for field line setting reflects light through the first reflector 2 and the second reflector 41. The second reflector 41 can effectively increase the reflective area and the viewing angle, so that the staff can quickly observe the point marking device; in a windy environment, the wind blows the second reflector 41 to move in the direction of the slide slot 33. Since the movement of the second reflector 41 includes rotation and revolution with the limit rod 32 as the center, the wind resistance is minimized when part of the second reflector 41 is parallel to the horizontal plane, thereby effectively avoiding the situation where the second reflector 41 cannot rotate due to excessive wind resistance, and it is easier to be observed.

[0032] like Figure 3-4 As shown, in a specific embodiment, the transmission mechanism includes a transmission rod 42, a docking plate 43 and an abutting rod 44; the length direction of the transmission rod 42 extends along the length direction of the second reflector 41 and is connected to the second reflector 41, a through hole is provided on the side wall of the linkage frame 31, the transmission rod 42 passes through the through hole and is movably connected to the linkage frame 31, the docking plate 43 is perpendicular to the transmission rod 42 and connects the transmission rod 42 and the abutting rod 44, and one end of the abutting rod 44 away from the docking plate 43 is movably arranged in the slide groove 33. The abutting rod 44 slides in the slide groove 33, so that the docking plate 43 can drive the transmission rod 42 and the second reflector 41 to move synchronously.

[0033] like Figure 2-3 As shown, in a specific embodiment, the slide slot 33 has a first position and a second position along the length direction of the support rod 1, the first position is the highest position of the slide slot 33 on the limit rod 32, and the second position is the lowest position of the slide slot 33 on the limit rod 32, and there is a preset height difference between the first position and the second position. It is precisely because of the height difference between the highest position and the lowest position of the slide slot 33 that the slide slot 33 has a groove body with a downward trend and a groove body with an upward trend on the limit rod 32, so that the wind-blowing transmission mechanism can drive the second reflector 41 to rotate during the movement in the slide slot 33, and a part of the second reflector 41 can be perpendicular to the length direction of the support rod 1, thereby reducing wind resistance, so that the entire linkage mechanism 3 and the movable reflector mechanism 4 can be blown even when the wind force is small.

[0034] like Figure 1-4 As shown, in a specific embodiment, the first reflective plate 2 has a first reflective surface 21, and the first reflective surface 21 is perpendicular to the length direction of the support rod 1. The second reflective plate 41 has a second reflective surface 45. Among the plurality of second reflective plates 41, the second reflective surface 45 of at least one second reflective plate 41 can be perpendicular to the length direction of the support rod 1. Specifically, the first reflective surface 21 is the top of the first reflective plate 2, and the second reflective surface 45 is the two opposite side walls of the second reflective plate 41.

[0035] like Figure 1-4 As shown, in a specific embodiment, the transmission mechanism further includes a ball, which is disposed at the end of the abutment rod 44 and rolls in the slide groove 33 . The ball can reduce the friction resistance between the abutment rod 44 and the slide groove 33 .

[0036] In addition, the linkage frame 31 is in the shape of a cross as a whole, and a base 11 is provided at one end of the support rod 1 away from the first reflector 2, and the first reflector 2 and the base 11 are connected to the support rod 1 through a screw 5. At least one ground nail 12 is provided on the side of the base 11 away from the support rod 1, and a plurality of barbs are provided at intervals on the outer wall of the ground nail 12, and the device as a whole can be firmly fixed on the ground in the wild through the ground nail 12 and the barbs. Generally speaking, when the linkage frame 31 is in the shape of a cross as a whole, the number of second reflectors 41 is 4, and they are respectively provided in four directions of the linkage frame 31. Among the four second reflectors 41, the reflective surface of one second reflector 41 can be along the length direction of the support rod 1, and the others can be inclined or parallel to the horizontal plane.

[0037] In this embodiment, the first reflector 2 is connected to the top of the support rod 1, and the base 11 is connected to the bottom of the support rod 1. Specifically, screw holes are provided at the upper and lower ends of the support rod 1, and screw rods 5 are provided at the center of the first reflector 2 and the base 11. The screw rods 5 are detachably screwed and connected in the screw holes. The detachable structure makes it easy for the staff to disassemble and assemble the entire device. When in use, the entire device is supported by the support rod 1, and the first reflector 2 and the second reflector 41 in the movable reflective mechanism 4 are used for reflection at the same time. In a windy environment, the wind blows the second reflector 41 and the linkage frame 31 to rotate on the support rod 1 as a whole. The transmission mechanism allows the second reflector 41 to unfold to face the wind when it is on the windward side, and to rotate to minimize its wind resistance when it is on the leeward side.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
