One end of the pile 18 is detachably inserted into the connecting sleeve 21, and the other end is suspended and has a tip. The shock assembly includes a compression spring 23 and an inertia latch 30. The compression spring 23 is sleeved on the connecting sleeve 21 and located above the retainer ring 213, and in an initial state, the compression spring 23 is in a compressed state, for example, a pressing structure is adopted to press the compression spring 23 downwards, so that the compression spring 23 is compressed. The inertia clip 30 includes a trigger ring 35, an annular rail 32, and two stop assemblies. The trigger ring 35 is slidably sleeved on the connecting sleeve 21, an annular sliding cavity is formed in the trigger ring, two support plates 36 are arranged in the sliding cavity, and the two support plates 36 are respectively positioned at the left side and the right side of the connecting sleeve 21 and extend along the radial direction of the connecting sleeve 21; the annular rail 32 is fixedly connected to two support plates 36 and is arranged coaxially with the firing ring 35.

Each telescoping block includes an inertia block 31 and a detent 34. The inertia mass 31 is in sliding engagement with the annular track 32. The bayonet pins 34 are telescopically arranged on the inner side of the inertia block 31 relative to the inertia block 31, and one surface of each bayonet pin 34 matched with the cambered surface of the sliding groove is a cambered surface, so that the bayonet pins 34 can be conveniently separated from the sliding groove along the telescopic block.

In this embodiment, the perforating device further includes a first jack screw 13, the first jack screw 13 is detachably inserted into the connecting sleeve 21, and the inner end of the first jack screw 13 abuts against the supporting shaft 12, and the connecting sleeve 21 and the supporting plate 36 are fixed by tightening the first jack screw 13 after the perforating device stops swinging.

In this embodiment, the drilling device further includes a second jack 214, the second jack 214 is detachably inserted into the sleeve 211, and the inner end of the second jack 214 abuts against the pile 18, the pile 18 is fixed to the connecting sleeve 21 by tightening the second jack 214, and when the drilling device stops swinging, the second jack 214 is loosened, so that the pile 18 slides down along the connecting sleeve 21.
