High-precision gold mine drilling device

Abstract

The invention discloses a high-precision gold mine drilling device which comprises a main shell, a pushing block is fixedly installed on the side wall of the main shell, the interior of the pushing block is of a hollow structure, a connecting rod is slidably connected to the interior of the pushing block in a sleeved mode, the connecting rod is slidably connected with a sliding block in a sleeved mode, and a spring is fixedly installed on one side of the sliding block. The spring is movably connected to the outer portion of the connecting rod in a sleeving mode, a movable ferrule is installed on the outer wall of the connecting rod, one side of the movable ferrule is connected with one end of the spring, an annular check ring is fixedly installed at one end of the connecting rod, elastic blocks are arranged on one side of the annular check ring in a circumferential distribution mode, and a check block is connected to one end of the connecting rod. And a screw hole is formed in one side of the movable ferrule in a penetrating mode, an adjusting screw is movably installed in the screw hole through threads, the bottom of the adjusting screw makes contact with the outer wall of the connecting rod, and the problem that the practicability is poor at present is solved.
