[0021] Please refer to Figure 2 , in this embodiment, the adjustment component 2 includes a fixing frame 201, an adjustment rod 202, an adjustment sleeve 203, a limit chute 204 and a limit slider 205; an adjustment sleeve 203 is fixedly connected to the middle position of the upper end of the fixing frame 201; the staff operates the knob at the upper end of the adjustment rod 202 to drive the adjustment rod 202 to move downward inside the adjustment sleeve 203, thereby driving the positioning box 1 to descend inside the fixing frame 201. The pointed part at the lower end of the positioning box 1 drills a hole in the ground, making the positioning position of the drilling more obvious. The adjustment rod 202 is threadedly connected to the inside of the adjustment sleeve 203; long strip-shaped limit chutes 204 are opened on both sides of the fixing frame 201; limit sliders 205 are fixedly connected to both the left and right ends of the positioning box 1; the limit chute 204 and the limit slider 205 are slidably connected; when the positioning box 1 descends or ascends, the limit sliders 205 arranged on both sides slide inside the limit chutes 204 of the fixing frame 201 to ensure the stability of the drilling of the positioning box 1. The recording component 4 includes a storage box 401, a tape measure 402 and an insertion rod 403; a disc-shaped tape measure 402 is installed inside the storage box 401; a handwheel for helping the tape measure 402 to wind up is arranged at the lower end of the tape measure 402; the insertion rod 403 is pulled out and inserted into the starting point, and the positioning device is pushed to move. The end of the tape measure 402 is fixedly connected to the insertion rod 403 for inserting into the ground. The tape measure 402 is pulled out from the storage box 401 to record the walking distance and improve the accuracy of the marked position for blasting in open-pit coal mines.

[0022] Please refer to Figures 3 - 4 , in this embodiment, the marking component 5 includes a powder storage tank 501, a blanking hopper 502, a blanking channel 503 and a flow valve 504; a conical blanking hopper 502 is fixedly connected to the lower end of the powder storage tank 501; the inner side of the powder storage tank 501 is filled with marked powder with color, and a blanking channel 503 is arranged on the inner side of the pointed end of the blanking hopper 502; a flow valve 504 is installed outside the blanking channel 503; after reaching the designated position, stop, open the flow valve 504 of the blanking channel 503, and the marked powder with color leaks out for marking the drilling position.
