[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] Reference Figure 1-Figure 3 , a positioning rod for fixing an RTK surveying instrument, comprising.

[0021] The main rod body 1, the top of the main rod body 1 is coaxially fixedly connected with RTK2, the main rod body 1 is fixedly connected with a positioning ring 3, the output end of the positioning ring 3 is fixedly connected with a handbook 4, the RTK2 can realize the basic measurement function of the device, and the setting of the handbook 4 can facilitate the staff to better collect the measurement data;

[0022] A threaded rod 5 is coaxially fixedly connected to the bottom of the main rod body 1, and a matching cross rod 6 is fixedly connected to the bottom of the threaded rod 5. A support adjustment mechanism is provided on the threaded rod 5, and a cross plug plate 7 is fixedly connected to the bottom of the matching cross rod 6. When facing unpaved roads or soft soil conditions, the cross plug plate 7 can be inserted into the soil to better fix the device;

[0023] The support and adjustment mechanism includes a threaded sleeve 8, a rotating sleeve 9, a groove and an adjusting arm 10. The threaded sleeve 8 is threadedly connected to the threaded rod 5, the rotating sleeve 9 is rotatably connected to the bottom of the threaded sleeve 8, four grooves are opened on the rotating sleeve 9, the adjusting arm 10 is rotatably connected in the groove, four through-slide grooves are opened on the matching cross rod 6, and a support arm 11 is slidably connected in the through-slide groove. The support arm 11 is rotatably connected to the adjusting arm 10 on the corresponding side, and four limiting slide grooves are opened on the matching cross rod 6. A sliding seat 12 is slidably connected in the limiting slide groove. A matching rotating seat 13 is fixedly connected to the sliding seat 12, and the matching rotating seat 13 is rotatably connected to the middle position of the adjusting arm 10 on the corresponding side. When facing a paved road, the device needs to be supported and fixed at multiple angles or when facing an unpaved road. When the road is being worked, when the adjusting arm 10 needs to be pushed deeper into the soil, the height of the supporting arm 11 needs to be adjusted by adjusting the supporting adjusting mechanism. It is only necessary to manually rotate the threaded sleeve 8. Since the threaded sleeve 8 is rotatably connected to the rotating sleeve 9, when the threaded sleeve 8 rotates, since it is threadedly connected to the threaded rod 5, the rotating sleeve 9 will move axially along the threaded rod 5, thereby changing the angle of the adjusting arm 10 rotatably connected thereto. When the threaded sleeve 8 and the rotating sleeve 9 move up or down, the adjusting arm 10 is tilted through the support of the rotating seat 13. At this time, each supporting arm 11 will slide in the through-slot and approach or move away from each other, and the relative distance between the supporting arm 11 and the cooperating cross rod 6 will decrease or increase, thereby realizing the adjustment of the supporting arm 11.

[0024] The functional principle of the utility model can be explained through the following operation modes:

[0025] RTK2 can realize the basic measurement functions of the device, and the setting of handheld 4 can facilitate the staff to better collect measurement data;

[0026] When facing unpaved roads or soft soil conditions, the cross plug plate 7 can be inserted into the soil to better fix the device;

[0027] When facing a paved road and needing to support and fix the device at multiple angles, or facing an unpaved road and needing to push the adjusting arm 10 deeper into the soil, it is necessary to adjust the height of the supporting arm 11 by adjusting the supporting adjusting mechanism, which only requires manually rotating the threaded sleeve 8. Since the threaded sleeve 8 is rotatably connected to the rotating sleeve 9, when the threaded sleeve 8 rotates, since it is threadedly connected to the threaded rod 5, the rotating sleeve 9 will move axially along the threaded rod 5, thereby changing the angle of the adjusting arm 10 rotatably connected thereto. When the threaded sleeve 8 and the rotating sleeve 9 move up or down, the adjusting arm 10 is tilted through the support of the cooperating rotating seat 13. At this time, each supporting arm 11 will slide in the through-slot and approach or move away from each other, and the relative distance between the supporting arm 11 and the cooperating cross rod 6 will decrease or increase, thereby realizing the adjustment of the supporting arm 11.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
