Clamp ring；Described fixing pin one end forms taper bit；The described fixing pin other end forms hexagonal connection-peg；
In the middle of described connecting portion, upper end offers the perforation coordinated with described shank；Described drilling pipe upper end forms polygon and connects recessed
Mouthful；Described handle assembly one end forms the drilling pipe joint being connected mating recesses with described polygon, described drilling pipe tip side
Face forms fixing pin connecting hole；It is fixedly connected with Magnet bottom described fixing pin connecting hole；The described handle assembly other end
Form main frame joint；The fixing pin connecting hole coordinated with described connection-peg is offered on described main frame joint；Described determines
Position seat, drilling pipe, adjusting nut part, fixing pin, tighten handle and handle assembly to be respectively adopted rustless steel one-body molded.
Preferably: described positioning seat outer wall forms two symmetrical handle portions.
Compared with prior art, the invention has the beneficial effects as follows: during use, first according to practical situation, by adjusting nut
Part is threaded in the correct position piercing distance adjustment outer wall, by handle main frame adaptor cup jointing at described fixing pin connection-peg
On, then positioning seat is fixed on skull position to be punctured, the drilling pipe after regulation is plugged in the through hole in hole, location, will be fixing
Pin is plugged in the perforation of drilling pipe；Pinch on the other hand the handle portion in hole, location, be rotated down handle assembly on the other hand, drive fixing pin with
Handle assembly to rotate downwardly together, make taper bit enter skull appropriate depth；Now handle assembly is taken off, by handle group
The main frame joint of part is plugged on the polygon of described drilling pipe and connects in recess, owing to Magnet exists, makes main frame joint to insert all the time
It is connected on described polygon to connect in recess, now opens main frame, and pinch the handle portion positioning hole, make brill tooth along with drilling pipe
Rotate while moving down, when adjusting nut part outer wall offsets with positioning seat, it is meant that skull is the most drilled to be opened, due to outer spiral shell
Stricture of vagina is left hand thread, and drilling pipe turns clockwise, and now drilling pipe has movement tendency upwards can't continue to move down, due to
The existence of Magnet, makes fixing pin drive skull block close to Magnet, so only need to be by Host Shutdown and by this electronic dynamic drill for craniotomy
External member is taken off, it becomes possible to be together removed by the skull block being connected to fixing pin one end.

Detailed description of the invention
Below according to accompanying drawing, the detailed description of the invention of the present invention is made a detailed explanation.
According to shown in 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 described through hole equally distributed four positioning needles 12 of circumference；Described drilling pipe includes the drilling pipe portion 21 of cylinder, is molded over described
The piercing distance adjustment 22 and be molded over the connecting portion 23 of upper end, described drilling pipe portion of upper end, drilling pipe portion；Described drilling pipe subordinate
