Form the internal thread with external screw thread cooperation；The adjusting nut part lower end, which forms, to be plugged in the through hole of positioning seat
Clamp ring；Described fixed pin one end forms taper bit；The fixed pin other end forms hexagonal connection-peg；
Upper end offers the perforation with fixed pin cooperation among the connecting portion；The drilling pipe upper end forms polygon connection
Recess；Described handle assembly one end forms the drilling pipe connector that mating recesses are connected with the polygon, the drilling pipe connector
End face forms fixed pin connecting hole；The fixed pin connecting hole bottom is fixedly connected with magnet；The handle assembly is another
End forms host connector；The fixed pin connecting hole with connection-peg cooperation is offered on the host connector；Described
Positioning seat, drilling pipe, adjusting nut part, fixed pin tighten handle and stainless steel integrated molding is respectively adopted in handle assembly.
Preferably：There are two symmetrical handle portions for the positioning seat outer wall shaping.
Compared with prior art, the beneficial effects of the invention are as follows：In use, first according to actual conditions, by adjusting nut
Part is threaded in the suitable position for piercing distance adjustment outer wall, by handle host adaptor cup jointing in the fixed pin connection-peg
On, positioning seat is then fixed on skull position to be punctured, the drilling pipe after adjusting is plugged in the through hole of location hole, by fixation
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 fixed pin with
It handle assembly to rotate downwardly together, taper bit is made to enter skull appropriate depth；Handle assembly is removed at this time, by handle group
The host connector of part is plugged in the polygon connection recess of the drilling pipe, since magnet exists, host connector is enable to insert always
It is connected in the polygon connection recess, opens host at this time, and pinch the handle portion of location hole, make brill tooth with drilling pipe one side
Rotation is while move down, when adjusting nut part outer wall offsets with positioning seat, it is meant that skull is just drilled to be opened, due to outer spiral shell
Line is left hand thread, and drilling pipe rotates clockwise, and drilling pipe has upward movement tendency to will not continue to move down at this time, due to
The presence of magnet makes fixed pin drive skull block close to magnet, so only need to be by Host Shutdown and by the electronic dynamic craniotomy drill
External member is removed, it becomes possible to be removed the skull block for being connected to fixed pin one end together.

Specific embodiment
The specific embodiment of the present invention is made a detailed explanation below according to attached drawing.
According to Fig. 1 to Fig. 5, a kind of driven opening cranium drill bit described in the present embodiment includes positioning seat 1, grafting
Drilling pipe 2 in the positioning seat is threaded in the adjusting nut part 3 of the drilling pipe outer wall, is slidably connected at the drilling pipe
Interior fixed pin 4 and handle assembly 5；Circular through hole 13 is offered on the positioning seat；The positioning seat lower end forms
Along circumferentially equally distributed four pilot pins 12 of the through hole；The drilling pipe includes cylindrical drilling pipe portion 21, is molded over described
The connecting portion 23 for piercing distance adjustment 22 and be molded over drilling pipe portion upper end of drilling pipe portion upper end；The drilling pipe subordinate
End, which forms, bores tooth 20；The distance adjustment side wall upper part that pierces forms left-handed external screw thread 221；The adjusting spiral shell
Parent part inner wall forms the internal thread 32 with external screw thread cooperation；The adjusting nut part lower end, which forms, is plugged on positioning
Clamp ring 31 in the through hole of seat；Described fixed pin one end forms taper bit 41；The fixed pin other end forms
Hexagonal connection-peg 42；Upper end offers the perforation 232 with fixed pin cooperation among the connecting portion；The drilling pipe
Upper end forms polygon connection recess 231；Described handle assembly one end is formed is connected mating recesses with the polygon
Drilling pipe connector 52, the drilling pipe connector end face forms fixed pin connecting hole 522；The fixed pin connecting hole bottom, which is fixed, to be connected
It is connected to magnet 521；The handle assembly other end forms host connector 51；Offered on the host connector with it is described
The fixed pin connecting hole 511 of connection-peg cooperation；The positioning seat, drilling pipe, adjusting nut part, fixed pin, tighten handle and
Stainless steel integrated molding is respectively adopted in handle assembly.
There are two symmetrical handle portions for the positioning seat outer wall shaping.
In use, first according to actual conditions, adjusting nut part is threaded in and pierces the suitable of distance adjustment outer wall
Position, as shown in Fig. 2, then on the fixed pin connection-peg handle host adaptor cup jointing is fixed on skull by positioning seat
Drilling pipe after adjusting is plugged in the through hole of location hole, fixed pin is plugged in the perforation of drilling pipe by position to be punctured；On the other hand
The handle portion of location hole is pinched, is rotated down handle assembly on the other hand, fixed pin is driven to make as handle assembly rotates downwardly together
Taper bit enters skull appropriate depth；Handle assembly is removed at this time, as shown in figure 3, the host connector of handle assembly is inserted
It is connected in the polygon connection recess of the drilling pipe, since magnet exists, host connector is enable to be plugged on the polygon always
It connects in recess, opens host at this time, and pinch the handle portion of location hole, make brill tooth as drilling pipe rotates while to moving down
It is dynamic, when adjusting nut part outer wall offsets with positioning seat, it is meant that skull is just drilled to be opened, since external screw thread is left hand thread,
And drilling pipe rotates clockwise, drilling pipe has upward movement tendency to will not continue to move down at this time, due to the presence of magnet, makes
Fixed pin drives skull block close to magnet, so need to only be removed by Host Shutdown and by the electronic dynamic craniotomy drill external member, with regard to energy
It is enough to be removed together the skull block for being connected to fixed pin one end.
