Underground coal mine drilling anti-inclination device

The invention relates to the technical field of drilling, in particular to an underground coal mine drilling anti-inclination device which comprises a stabilizing frame, a guide pipe, a triangular plate, a mounting plate, a nail plate and the like. A guide pipe penetrates through the middle of the stabilizing frame, triangular plates are symmetrically and fixedly connected to the two sides of the stabilizing frame, bearing plates are fixedly connected to the triangular plates, extending plates are hinged to the two sides of the bearing plates, the extending plates have a vertical state and a horizontal state, the extending plates on the same side of the bearing plates on the two sides are jointly and fixedly connected with a mounting plate, and the mounting plate is slidably connected with a nail plate through a straight nail. And the straight ground nail is fixedly connected to the nail plate. Under the state that the bearing plate and the extension plate can be folded, the straight ground nails and the spir
