[0032] Workflow: When assembling the device, place the fixed rectangular plate 7 inside the placement groove 83 opened on the cylindrical body 81, and then slide the two internally threaded hole connecting columns 3 inside the first welding groove 5 and the second welding groove 6 opened on the cylindrical body 81 and the fixed rectangular plate 7. At the same time, the outer side of the internally threaded hole connecting column 3 slides inside the jack 82. At this time, the outer side of the internally threaded hole connecting column 3 is in close contact with the inner side of the jack 82 opened on the cylindrical body 81, and the internally threaded hole connecting column 3 is in close contact with the inner sides of the first welding groove 5 and the second welding groove 6 opened on the fixed rectangular plate 7. Then weld the two internally threaded hole connecting columns 3 and the fixed rectangular plate 7. At this time, the internally threaded hole connecting column 3 and the fixed rectangular plate 7 form an integral body. At this time, the part of the front end of the internally threaded hole connecting column 3 protruding from the front end of the cylindrical body 81. Install the other internally threaded hole connecting columns 3 and fixed rectangular plates 7 inside the cylindrical body 81 in the same operation method as above, weld the internally threaded hole connecting column 3 and the fixed rectangular plate 7, move the double-column groove 2 opened on the inner side of the connecting whole ring 1 to align with the internally threaded hole connecting column 3. At this time, the connecting whole ring 1 is in close contact with the outer sides of multiple internally threaded hole connecting columns 3 through the double-column groove 2. When the rear end of the connecting whole ring 1 is in close contact with the front end of the cylindrical body 81, screw the limiting threaded column 4 with the internally threaded hole connecting column 3 through the double-column groove 2. When the cylinder at the front end of the limiting threaded column 4 is in close contact with the front end of the double-column groove 2, the connecting whole ring 1 and the cylindrical body 81 are fixed at this time. Fix the other cylindrical bodies 81 in this way. At this time, the overall assembly of the device is completed. By operating the angle adjustment component 9 connected between the cylindrical body 81 and the small arm 86 of the bracket, rotate the operating block 91 with an external tool. The operating block 91 drives the double-threaded rotating rod 92 to rotate. The outer side of the double-threaded rotating rod 92 is in spiral fit with the inner side of the threaded hole groove 97 opened on the inner side of the first internally threaded cylinder 93, and at the same time, the outer side of the double-threaded rotating rod 92 is in spiral fit with the threaded hole groove 97 opened on the inner side of the second threaded cylinder 95. When rotating the operating block 91, the first internally threaded cylinder 93 and the second threaded cylinder 95 move away from the operating block 91 at the same time. At this time, rotation occurs between the first internally threaded cylinder 93 and the first ear seat 94, and rotation occurs between the second threaded cylinder 95 and the second ear seat 96. At this time, the second ear seat 96 drives the small arm 86 of the bracket to rotate. The small arm 86 of the bracket rotates around the bearing between the rotation-limiting seat 85 and the small arm 86 of the bracket. The small arm 86 of the bracket and the rotation-limiting seat 85 play a role in limiting the movement of the first internally threaded cylinder 93 and the second threaded cylinder 95. When the small arm 86 of the bracket rotates to the specified angle, it is okay. Adjust the rotation angle of the other small arms 86 of the bracket. At this time, the assembly can be completed. Before adjustment, the small arm 86 of the bracket and the large arm 84 of the bracket are in a horizontal state. At the same time, under the support of the angle adjustment component 9, there is a spacing between the small arm 86 of the bracket and the large arm 84 of the bracket. The device is provided with several modular components, which disperse the volume and weight of the overall device, facilitate transportation in complex terrains or ocean voyages, reduce the difficulty of transportation, and at the same time, the device can be disassembled for easy later maintenance.
