The piercing distance adjustment and be molded over the knob of upper end, described drilling pipe portion of upper end, portion；Described drilling pipe subordinate's end forms
Bore tooth；The described distance adjustment side wall upper part that pierces forms external screw thread；Described adjusting nut part include with described outside
The nut that screw thread connects；Described nut inner wall forms female thread；Described fixing needle assembly include taper bit with
And handle；Connecting rod is formed between described taper bit and handle；It is socketed with in described connecting rod to fix with handle and is connected
Spring；In the middle of described knob, upper end offers the perforation coordinated with described connecting rod；Described positioning seat, drilling pipe, regulation
It is one-body molded that nut piece and fixing needle assembly are respectively adopted rustless steel.
Preferably: described positioning seat outer wall forms two symmetrical handle portions.
Preferably: the described distance adjustment lower sidewall that pierces offers multiple draw-in groove；Described draw-in groove edge
Pierce the circumferentially equidistant from distribution of distance adjustment；Described nut lower end forms the clamping in the through hole being plugged on positioning seat
Circle, connects inside described clamp ring and has and the elastic chuck of described card slot fit, and described draw-in groove secures with elastic chuck
Adjusting nut part is relative to the position of drilling pipe.
Preferably: in the middle of described knob, upper end offers the recess coordinated with described handle, it is to avoid turning
Drilling pipe is driven to rotate together during dynamic handle.
Compared with prior art, the beneficial effects of the utility model are: during use, first according to practical situation, and will regulation
Nut piece is threaded in the correct position piercing distance adjustment outer wall, and then positioning seat is fixed on skull position to be punctured
Put, the drilling pipe after regulation is plugged in the through hole in hole, location, fixing needle assembly is plugged in the perforation of drilling pipe；Pinch on the other hand
The handle portion in hole, location, is rotated down handle on the other hand, makes taper bit enter skull appropriate depth, under fixing needle assembly entirety
Time sliding, spring contraction；Now doctor pinches the handle portion in hole, location, rotary knob portion on the other hand on the other hand, due to spring contraction, will bore
Tooth is against on skull, rotary knob portion when, bores tooth and moves down along with drilling pipe rotates, when adjusting nut part
When the projection of outer wall and positioning seat offset, it is meant that skull is the most drilled to be opened, owing to taper bit is fixed on the skull after being drilled
On block, so only this manual drill for craniotomy external member need to be taken off, now extend due to spring, by the skull block on taper bit,
It is positioned at drilling pipe inside thus is removed.

Detailed description of the invention
Below according to accompanying drawing, detailed description of the invention of the present utility model is made a detailed explanation.
According to shown in Fig. 1 to Fig. 3, the manual drill for craniotomy of one described in the present embodiment, include positioning seat 1, be plugged on institute
State the drilling pipe 2 in positioning seat, be threaded in the adjusting nut part 3 of described drilling pipe outer wall, and be slidably connected at described drilling pipe
Interior fixing needle assembly 4；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 upper end, described drilling pipe portion
Pierce distance adjustment 22 and be molded over the knob 23 of upper end, described drilling pipe portion；Described drilling pipe subordinate's end forms brill
