Compared with prior art, the beneficial effects of the invention are as follows：Before use, first according to actual conditions, by adjusting nut
Part is threaded in the correct position for piercing distance adjustment outer wall, and positioning seat then is fixed on into skull position to be punctured, will
Drilling pipe after regulation is plugged in the through hole of positioning hole, and spring is socketed on the outside of fixed pin, and fixed pin insertion is tightened into handle
In the second middle perforation, cam pack is rotatably connected on fixed pin top by bolt, by mounted fixed pin grafting
In the perforation of drilling pipe；Cam pack is rotated to projection is made in positioning hole, with the handle for pinching positioning hole on the other hand during use
Hand, the handle of cam pack is rotated down on the other hand, taper bit is entered skull appropriate depth, now rotate raised component
180°；With the handle portion for pinching positioning seat on the other hand, proficiency turn knob portion, due to spring contraction, tooth will be bored and be pushed against on skull,
When turn knob portion, bore tooth as drilling pipe rotate while move down, when the raised of adjusting nut part outer wall and
When positioning seat offsets, it is meant that skull is just drilled to be opened, because taper bit is fixed on the skull block after being drilled, so only needing
Raised component is turned to perpendicular to handle end face is tightened, now because spring extends, by the skull block on taper bit, position
So as to being removed inside drilling pipe.
