Drilling device based on automobile parts

The drilling device comprises a drilling machine, the bottom of the drilling machine is fixedly connected with a base, the top of the base is fixedly connected with a transmission box, and the front face of the transmission box is provided with a rotating rod; the rear side of the rotating rod penetrates into the transmission box and is movably connected with the inner wall of the transmission box through a bearing. A rotating rod is manually rotated, the rotating rod drives a gear to rotate, the gear drives a toothed plate meshed with the top to move left and right, the toothed plate drives a connecting block to move left and right, the connecting block drives a supporting plate to move left and right, a pull plate drives a push plate to move rightwards, and the push plate drives a clamping block to move rightwards, so that the clamping block is clamped and sleeved on the surface of a limiting disc to limit the rotating rod; and therefore, the drilling machine has the advantage that the position is convenien
