When working, through the rotation of the middle bearing, the lower joint of the drill rod lifting device 6 rotates with the drill rod 7 to drill, at the same time, the output torque of the power head is eliminated, so that the steel wire rope will not be scattered due to loose twist.

[0027] The upper joint side of the drill rod lifting device 6 is fixedly connected with a coupling plate 11, the coupling plate 11 is slidably installed on the guide structure of the mast 1 based on the drill rod lifting device follower 12.
