After the left guide 6 and the right guide 9 are fixedly connected through the upper guide connecting shaft 8 and the lower guide connecting shaft 12, the plurality of rollers 6-3 can rotate by taking the steel pipe 6-5 where the rollers are located as an axis, and the function of guiding the clamped drill rod can be realized.
The gripper unscrewing process: the upper connecting shaft 7, the upper guiding connecting shaft 8, the lower guiding connecting shaft 12 and the lower connecting shaft 13 of the clamp holder are removed, so that the left guide piece 6 and the right guide piece 9 as well as the left clamping piece 4 and the right clamping piece 11 can be separated, and the left clamping piece 4 and the right clamping piece 11 respectively rotate outwards around the left rotating shaft 3 and the right rotating shaft 15, so that the clamp holder is unscrewed, as shown in fig. 2.
When the gripper is unscrewed, the left gripping oil cylinder 4-3 can be retracted firstly to drive the left gripping block 4-4 and the left dental plate 4-6 to move horizontally backwards, and similarly, the right gripping oil cylinder 11-3 executes the same action as the left gripping oil cylinder 4-3. And then all the connecting shafts are dismantled to realize the unscrewing of the clamp holder.
