Internal water spraying type guide ring structure

Abstract

The utility model relates to the technical field of oral implanting tools, and discloses an internal water spraying type guide ring structure which comprises a guide ring body, a sliding resisting assembly is arranged at the bottom of the guide ring body and comprises a clamping ring, a clamping block, a movable clamping plate and a fixed ring, the clamping ring is movably connected with the guide ring body, the clamping block is fixedly connected with the clamping ring, and the movable clamping plate is elastically connected with the clamping ring. The fixing ring is in threaded connection with the guide ring main body and is clamped with the clamping block; the water conveying hole channel is formed in the clamping ring and is far away from the movable clamping plate and the clamping block while being far away from the smooth surface of the drill bit, the drill bit can be better fixed through the clamping block and the movable clamping plate without water source lubrication, and then the anti-sliding effect is achieved, so that the deviation phenomenon caused by high-speed rotation of the drill bit is avoided, and falling and direction deviation of the drill bit are avoided; therefore, safety accidents are avoided.
