When the vibration is finished and the rotary drilling operation is continued, the fixing block of the fixing member 16 is driven by the driving part to rotate back to the gap between the first fixing disk 161 and the second fixing disk 165 relative to the first fixing disk 161 and the second fixing disk 165, and the first vibration saw teeth 1515 on the first vibration member 151 are engaged with the second vibration saw teeth 1521 on the second vibration member 152 under the elastic force of the vibration elastic member 153 connected to the fixing holding part 155, so that the fixing member 16 rotates along with the drilling bucket 12 in the second direction, and the first vibration member 151 does not bounce on the second vibration member 152.
In summary, the following steps:
the embodiment of the invention provides a rotary drilling tool 10 which has the characteristics of capability of generating vibration impact during drilling operation and high rock entering efficiency.
