[0002] A coal mine is an underground or open-pit mining site where coal resources are extracted. In a coal mine, miners use a variety of equipment and techniques to extract coal and transport it out. The coal mining industry has grown rapidly around the world and is widely used in power generation, manufacturing, heating and other industrial processes.

[0003] A drilling machine can perform geological exploration, gas extraction, and coal seam ventilation on coal seams, thereby ensuring safe mining of coal mines. Before using a drilling machine, a locator is required for positioning, so that the coal seam can be accurately located to ensure the accurate position and direction of the drill hole. When using a locator for positioning, a supporting device is required to support the locator body. Most of the existing supporting devices use a tripod. Since the tripod itself is large and the tripod is long and cannot be disassembled, it is not convenient to put the tripod into a backpack.

A threaded sleeve 15 that cooperates with the fixing plate 4 is threadedly connected to the screw 14. A pointed cone 22 is fixedly connected to one end of the screw 14. A through hole 20 that cooperates with the pointed cone 22 is provided on the fixing plate 4. A first stud 5 is threadedly connected to the bottom surface of the fixing plate 4. A connecting sleeve 6 is fixedly connected to one end of the first stud 5. A second stud 7 is threadedly connected to the connecting sleeve 6. The base 1 is horizontally adjusted by the screw 14, the threaded sleeve 15, the pointed cone 22 and the through hole 20, and the fixing plate 4 is connected to the base 1 by the first stud 5 and the connecting sleeve 6.

[0024] like Figure 2As shown, a support block 8 arranged in a ring is provided below the second stud 7, and there are three support blocks 8 arranged in a ring. A protrusion 16 is provided on one side of the support block 8, and a first slot 17 cooperating with the protrusion 16 is provided on the other side of the support block 8. A second slot 18 penetrating through the first slot 17 is provided on the support block 8, and a fixing column 19 is movably inserted on the second slot 18, and one end of the fixing column 19 is magnetically connected to the inner bottom surface of the second slot 18. The three support blocks 8 are fixed by the action of the protrusion 16, the first slot 17, the second slot 18 and the fixing column 19.

[0025] like Figures 3 to 5 As shown, a telescopic leg 9 is hingedly connected to the bottom surface of the support block 8, and the telescopic leg 9 includes a first connecting rod 21 hinged to the support block 8, a third slot is provided on the first connecting rod 21, and a second connecting rod 23 is movably inserted in the third slot, and a bolt 24 cooperating with the second connecting rod 23 is threadedly connected on the first connecting rod 21, and a fan-shaped screw hole 10 cooperating with the second stud 7 is provided on the support block 8. The length of the telescopic leg 9 is adjusted by rotating the bolt 24, and the height of the base 1 is adjusted by rotating the second stud 7.

[0026] In specific use, when the locator 2 is needed, the three support blocks 8 are taken out of the backpack, and then the protrusion 16 on one support block 8 is aligned with the first slot 17 on the other support block 8, and then the fixing column 19 is moved, and then the protrusion 16 is inserted into the first slot 17, and then the fixing column 19 is pressed to make it fit with the inner bottom surface of the second slot 18, thereby completing the fixation of the two support blocks 8, and then the protrusion 16 and the first slot 17 on the last support block 8 are aligned with the first slots 17 and the protrusion 16 on the other two, and then the two fixing columns 19 are moved, and then the third support block 8 is inserted to form a complete bracket, and then the fixing column 19 is pressed to complete the fixation of the support block 8, and then the telescopic leg 9 is moved, the bolt 24 is turned to adjust the length of the telescopic leg 9, and then the bolt 24 is tightened to support the telescopic leg 9 on the ground, and then the second stud 7 is put into the bracket composed of three support blocks 8.
