[0002] In mining, the drilling positioning of mining drills plays a vital role. Whether it is ore mining, tunnel excavation or geological exploration, mining production cannot be separated from drilling operations. Accurate drilling positioning can ensure that the borehole reaches the predetermined target position, laying a solid foundation for subsequent blasting, mining and other work.

[0003] The patent application with application number CN202410444383.5 discloses a drilling positioning device for a mining drill, comprising: a movable frame, on which a limit plate is arranged, a rotating block is rotatably arranged on the limit plate, a drill rod is arranged in the rotating block, and the rotation of the rotating block can drive the drill rod to rotate synchronously around the central axis of the rotating block, and ratchets are connected at both ends of the rotating block, and the two ratchets rotate in opposite directions; a sliding plate, which is slidably connected to a limit plate, and a first return spring is arranged between the sliding plate and the limit plate, and a slot that can cooperate with the ratchet is opened on the side wall of the sliding plate.
