The driving mechanism comprises a transmission shaft 2, a synchronous rotating ring 8 and a transmission mechanism; the transmission shaft 2 is rotatably and slidably inserted into the drilling housing 1, and the upper end of the transmission shaft 2 is connected with the driving shaft 101 to drive the transmission shaft 2 to rotate. The transmission shaft 2 is provided with a lifting groove which is matched with the drilling shell 1, the lifting groove is used for blocking the drilling surface 12 in the drilling process when the rotating speed of the drilling shell 1 is lower than that of the transmission shaft 2, and the rotating speed of the drilling shell 1 is reduced to enable the transmission shaft 2 to slide downwards relative to the drilling shell 1. The drive shaft 2 has a friction section on the circumferential wall of the drive shaft inside the drilling housing 1. The synchronous rotating ring 8 is internally provided with a rough surface 84, the synchronous rotating ring 8 is positioned in the drilling shell 1 and can be sleeved on the transmission shaft 2 in a vertically sliding manner and is configured to slide vertically and synchronously with the drilling shell 1, and the initial state is in contact with the friction section, so that the transmission shaft 2 drives the synchronous rotating ring 8 to rotate, when the transmission shaft 2 moves downwards relative to the synchronous rotating ring 8 to a preset distance, the synchronous rotating ring 8 is separated from the friction section, and further the synchronous rotating ring 8 is not in friction contact with the transmission shaft, so that the transmission shaft does not drive the synchronous rotating ring 8 to rotate.
