because second rack 23 rightward movement can drive long gear 22 and rotate, the number of teeth between the interval that removes the place on second rack 23 is the same with the number of teeth on long gear 22, second rack 23 offsets with long gear 22 when second rack 23 does not remove promptly, moves in second rack 23 rightward, and the number of teeth at the length place that second rack 23 removed is the same with the number of teeth on long gear 22, can just drive long gear 22 when accomplishing second rack 23 rightward and remove like this and accomplish a round and rotate.

The working principle of the invention is as follows: firstly, the driving box body 2 is slid on the hydraulic slide rail 1 through the external hydraulic equipment, when a stone block is encountered below a drill hole of the drill rod 3, the driving box body 2 is pressed downwards continuously, so that the positioning spring 27 is stretched, the outer side wall of the drill rod 3 positioned in the driving box body 2 is provided with a supporting part, and the drill rod 3 can continuously rotate on the fixed plate 25 all the time;

then the second rotating ring 17 is driven to twist to complete a circle under the action of the single-circle rotating part;

then, when the second rotating ring 17 starts to rotate, the lower convex block 18 and the upper convex block 19 which originally abut against each other will break away first, and the lower convex block 18 and the upper convex block 19 which do not abut against each other will be dislocated from each other, and under the action of the compression spring 20, the lifting ring 16 is driven to be lifted, so that the first rack 15 can be driven to be lifted; when the second rotating ring 17 rotates for one circle, the upper convex block 19 returns to the original position, the lower convex block 18 and the upper convex block 19 are pressed against each other again to drive the lifting ring 16 to descend, and finally the first rack 15 is driven to descend;

wherein, when swing stopper 13 does not stretch out swing groove 12, support and press slider 8 and can slide on vertical slide opening 6, when swing stopper 13 stretches out swing groove 12, just to supporting to press slider 8 to carry out effective spacing, avoided supporting to press the gliding of slider 8, when the second swivel becket 17 wrench movement accomplishes the round simultaneously, first rack 15 descends, let swing stopper 13 stretch out swing groove 12, provide the support to supporting to pressing slider 8 that has descending trend for segmentation spiral piece 51 can present the fixed state that fig. 2 shows.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered as the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
