The base box is a hollow rectangular structure, and the top is provided with a chip falling hole and a clamp holder. The positioning ring is provided with a fixing thread device and a pressing cylinder device. The fixing thread device and the pressing cylinder device are provided with a clamp head at the inner end.

[0005] However, this mechanism is suitable for drilling of gear plane, and is not suitable for drilling of oil hole in the direction of tooth surface. UTILITY MODEL CONTENTS
