The main purpose of setting the bearing 70 is to avoid the problem of increased friction caused by the sleeve 7 rotating directly in the mounting hole, a plug post 6 is sleeved in the sleeve 7, and a positioning bolt 8 is installed on the plug post 6 and the sleeve 7;

[0025] The positioning tube 4 is provided with a pick-up and placement mechanism with the function of picking up and placing the positioning frame 10. The pick-up and placement mechanism includes a platform 11 and a card plate 13. The positioning frame 10 is inserted into the platform 11. Card slots 100 are provided on the corresponding two sides of the positioning frame 10. The card plate 13 is inserted into the card slot 100. An insertion rod 14 is fixed to one side of the card plate 13. The insertion rod 14 is sleeved into the insertion tube 16. A spring 15 is sleeved on the insertion rod 14.

[0026] In this embodiment, a surveying and mapping UAV 1 is further included. A positioning frame and a positioning plate 9 are fixedly connected to the bottom of the fuselage of the surveying and mapping UAV 1. A motor 2 is installed in the positioning frame. A positioning tube 4 and a plug post 6 are fixedly connected to both sides of the positioning frame 10.

[0027] In this embodiment, the connecting shaft 3, positioning tube 4, plug column 6 and sleeve 7 are vertically penetrated with a socket, and the sockets of the connecting shaft 3 and positioning tube 4 are installed with a positioning bolt 1 5, and the sockets of the plug column 6 and sleeve 7 are installed with a positioning bolt 2 8.

[0028] In this embodiment, a placement groove 110 is opened in the middle of the platform 11 , and the placement groove 110 of the platform 11 and the top inner wall of the positioning frame 10 respectively abut against the bottom and top of the surveying instrument 18 .

[0029] In this embodiment, two “C”-shaped slots 111 are provided on the platform 11 , and the positioning frames 10 are inserted into the two “C”-shaped slots 111 . A sliding groove 112 is provided at the bottom of the platform 11 .

[0030] In this embodiment, the top of the card plate 13 is fixedly connected to a slider 12, and the slider 12 is slidably connected to the slide groove 112. One side of the card plate 13 is fixedly connected to a handle 130, and the insert 16 is fixedly connected to the mounting plate 17, and the mounting plate 17 is fixedly connected to the bottom surface of the platform 11.

[0031] The use method and advantages of this utility model: When the surveying instrument of this surveying drone is in use, the working process is as follows:

[0032] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, when the surveying instrument 18 needs to be installed, the installation process is as follows:

[0033] First, place the surveying instrument 18 in the placement slot 110 of the platform 11, then align the positioning frame 10 with the "C"-shaped slot 111 and insert it from top to bottom. At the same time, the operator holds the two handles 130 with one hand and pulls them toward the middle position. The handles 130 drive the card plate 13 to move toward the middle position. The movement of the card plate 13 is driven by the slider 12 sliding in the slide slot 112, causing the card plate 13 to move horizontally. The movement of the card plate 13 also causes the insertion rod 14 to enter the insertion tube 16, and the spring 15 is compressed at the same time.

[0034] When the positioning frame 10 contacts the top surface of the surveying instrument 18, the operator releases the handle 130, and the spring 15 rebounds to drive the insertion rod 14 to extend out of the insertion tube 16, and at the same time, the clamping plate 13 is clamped into the clamping slot 100, thus completing the rapid positioning of the surveying instrument 18;

[0035] When the surveying instrument 18 needs to be taken out, the operator only needs to hold the two handles 130 and pull them toward the middle position. The handles 130 drive the clamping plate 13 to move toward the middle position, so that the clamping plate 13 is disengaged from the clamping slot 100. Then, the positioning frame 10 is lifted upward from the platform 11 to remove the surveying instrument 18. The above content is an introduction to the quick removal and placement of the surveying instrument 18, and it also solves the problem of inconvenient assembly and disassembly of the surveying instrument 18.

[0036] After the positioning of the surveying instrument 18 is completed, the positioning cylinder 4 on the positioning frame 10 is inserted into the connecting shaft 3, and then the plug column 6 is pulled out of the sleeve 7, and then the bearing 70 is placed in the positioning plate 9, and then the positioning bolt 1 5 is positioned to position the connecting shaft 3 and the positioning cylinder 4, and the positioning bolt 2 8 is positioned to position the plug column 6 and the sleeve 7 in turn, and then the motor 2 is started. The rotation of the motor 2 rotates the connecting shaft 3, the positioning cylinder 4, the plug column 6, the sleeve 7 and the positioning bolt 2 8 as well as the surveying instrument 18 on the positioning frame 10, so that the surveying instrument 18 can adjust the angle, which is convenient for reducing the number of flights and shooting time of the drone, thereby improving the surveying efficiency.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
