Inwall forms the female thread with the cooperation of described external screw thread；Described adjusting nut part lower end forms and is plugged on the logical of positioning seat
The clamp ring of in the hole；Described fixing pin one end forms taper bit；The described fixing pin other end forms hexagonal inserting
Joint；In the middle of described connecting portion, upper end offers the perforation with the cooperation of described shank；Described drilling pipe upper end forms polygon
Connect recess；Described handle assembly one end forms the drilling pipe joint being connected mating recesses with described polygon, described drilling pipe
Joint end face forms fixing pin connecting hole；Described fixing pin connecting hole bottom is fixedly connected with Magnet；Described handle assembly
The other end forms main frame joint；Fixing pin connecting hole with the cooperation of described connection-peg is offered on described main frame joint.
Preferably：Described positioning seat outer wall forms two symmetrical handle portions.
Compared with prior art, the beneficial effects of the utility model are：During use, first according to practical situation, will adjust
Nut piece is threaded in the correct position piercing distance adjustment outer wall, and handle main frame adaptor cup jointing is inserted in described fixing pin
On joint, then positioning seat is fixed on skull position to be punctured, the drilling pipe after adjusting is plugged in the through hole of location hole, will
Fixing pin is plugged in the perforation of drilling pipe；Pinch the handle portion of location hole on the other hand, be rotated down handle assembly on the other hand, drive and fix
Pin rotates downwardly together with handle assembly, makes taper bit enter skull appropriate depth；Now handle assembly is taken off, will be
The polygon that the main frame joint of handss assembly is plugged on described drilling pipe connects in recess, because Magnet exists, so that main frame joint is begun
It is plugged on described polygon eventually to connect in recess, now opens main frame, and pinch the handle portion of location hole, make brill tooth with drilling pipe
Rotate while moving down, when adjusting nut part outer wall is offseted with positioning seat it is meant that skull is drilled open just, due to
External screw thread is left hand thread, and drilling pipe turns clockwise, and now drilling pipe has movement tendency upwards to will not continue to move down,
Due to the presence of Magnet, fixing pin is made to drive skull block close to Magnet, so only need to open by Host Shutdown and by this electronic moving
Cranium drill bushing part takes off it becomes possible to together be removed the skull block being connected to fixing pin one end.

Specific embodiment
Below according to accompanying drawing, specific embodiment of the present utility model is made a detailed explanation.
According to Fig. 1 to Fig. 5, a kind of driven opening cranium drill bit described in the present embodiment, include positioning seat 1, grafting
Drilling pipe 2 in described positioning seat, is threaded in the adjusting nut part 3 of described drilling pipe outer wall, is slidably connected at described drilling pipe
Interior fixing pin 4 and handle assembly 5；Manhole 13 is offered on described positioning seat；Described positioning seat lower end forms
Along equally distributed four positioning needles 12 of described through hole circumference；Described drilling pipe includes the drilling pipe portion 21 of cylinder, is molded over described
The connecting portion 23 piercing distance adjustment 22 and being molded over described drilling pipe portion upper end of drilling pipe portion upper end；Described drilling pipe subordinate
End forms brill tooth 20；The described distance adjustment side wall upper part that pierces forms left-handed external screw thread 221；Described regulation spiral shell
Parent part inwall forms the female thread 32 with the cooperation of described external screw thread；Described adjusting nut part lower end forms and is plugged on positioning
Clamp ring 31 in the through hole of seat；Described fixing pin one end forms taper bit 41；The described fixing pin other end forms
Hexagonal connection-peg 42；In the middle of described connecting portion, upper end offers the perforation 232 with the cooperation of described shank；In described drilling pipe
End forms polygon and connects recess 231；Described handle assembly one end forms and is connected mating recesses with described polygon
