As shown in fig. 3, the first stop member 62 is disposed at the upper portion of the housing 6, and the moving distance between the second rotating shaft 3 and the housing 6 can be adjusted by adjusting the length of the first adjusting member in the vertical direction, so that the second rotating shaft 3 and the first rotating shaft 2 rotate in cooperation to realize drilling.

The second rotation shaft 3 and the housing 6 are prevented from moving relatively in the up-down direction by the cooperation of the second stopper 9 and the inner wall of the housing 6.

In some embodiments, the first through hole 21 includes a first section 211 and a second section 212, an inner diameter of the first section 211 is smaller than an inner diameter of the second section 212, and the second rotation shaft 3 is fitted in the first section 211 and the second section 212. The second section 212 is internally provided with internal threads, and the second rotating shaft 3 positioned in the second section 212 is connected with the second section 212 through the threads.

The first section 211 has a first end (an upper end of the first section 211 shown in fig. 3) and a second end (a lower end of the first section 211 shown in fig. 3) opposite to each other in a length direction (an up-down direction shown in fig. 3) of the first rotating shaft 2, a polygonal interface matched with the anchor rod assembly is provided at the first end of the first section 211, and the second end of the first section 211 is connected with the first end of the second section 212.

The upper end of the first section 211 is a polygonal interface that mates with the bolt assembly, for example when a hex nut is used in the bolt assembly the upper end of the first section 211 is configured as a hexagonal interface to mate with the bolt assembly.

The second section 212 has internal threads therein, and external threads having the same direction as the internal threads in the second section 212 are provided on the peripheral side of the second rotating shaft 3 located in the second section 212.
