Special drilling and reaming integrated tool for processing steel bottle bottleneck and drilling and reaming integrated machine

The invention provides a special drilling and reaming integrated tool for processing a steel bottle bottleneck and a drilling and reaming integrated machine and belongs to the technical field of processing of steel bottle bottlenecks. The drilling and reaming integrated tool comprises a fixed bracket and a rotary bracket, wherein the middle part of the fixed bracket is connected with the middle part of the rotary bracket through a rotary pin shaft; a reaming cutter is fixedly connected with one end of the rotary bracket; a drilling bit is fixedly connected with the other end of the rotary bracket; the lower end of the fixed bracket is connected with the rotary bracket through a spring positioning pin mechanism. An operator replaces positions of the drilling bit and the reaming cutter through rotating the rotary bracket, and hole drilling and hole reaming operation of the steel bottle bottleneck is finished under the condition that a steel bottle is clamped in one step. 种钢瓶瓶口加工专用钻铰体工装以及钻铰体机，属于钢瓶瓶口加工设置的技术领域，所述钻
