The utility model relates to the technical field of drilling tools, and discloses an anti-stick-slip drilling tool which comprises a
drill bit, a
drill bit mounting mechanism is arranged at the bottom of the
drill bit, and an anti-stick-slip mechanism is arranged at the bottom of the
drill bit mounting mechanism. According to the anti-stick-slip
well drilling tool, a cross-shaped inserting block is inserted into a drill rod, a second bolt is inserted, a nut and a
gasket are utilized, the anti-stick-slip
assembly can be fixed, when the drill rod drives a
drill bit to rotate and stick-slip occurs, the
drill bit stops rotating, the drill rod then rotates, a connecting plate is driven to rotate, and the anti-stick-slip
assembly is fixed. At the moment, a movable column drives a screwing connecting column to rotate, the screwing connecting column is spirally bent in a circular groove column, and when the screwing connecting column is bent, the movable column moves in the circular groove column, so that a worker has enough time to stop rotation of the drill rod; due to the design of the bent screwing connecting column, enough buffer time is provided for the stick-slip situation, and the situation that the drill rod is damaged is avoided.
