Embodiments of the invention：As shown in Figure 1-Figure 3, one kind can spacing safe trepan device, including the body of rod 1, cutting teeth 2
With limiter 3, located at one end of the body of rod 1, the outer wall of the body of rod 1 is provided with external screw thread 4 to cutting teeth 2, and limiter 3 includes housing 7, pressure
Tight plate 8 and spring 10, have an accommodating chamber 11 with opening 12, pressure strip 8 and the socket connection of accommodating chamber 11 on housing 7,
And can be slided in accommodating chamber 11, spring 10 is in accommodating chamber 11 and is abutted against with the end of pressure strip 8, the center of housing 7
Position is provided with along its axial arranged first through hole 5, has the first internal thread 6 on the inwall of first through hole 5, is set on pressure strip 8
There is the second through hole 16, there is the second internal thread 15, the body of rod 1 and the through hole 16 of first through hole 5 and second on the inwall of the second through hole 16
Socket connection, and external screw thread 4 is meshed with the first internal thread 6 and the second internal thread 15；The through hole 16 of first through hole 5 and second it is straight
Footpath is all higher than the external diameter of the body of rod 1.
When using, the top of pressure strip 8 is pressed with hand, be pressed into accommodating chamber 11, now spring 10 is compressed, and works as pressure
After tight plate 8 is moved a certain distance, the axis collinear of first through hole 5 on the second through hole 16 and housing 7 on pressure strip 8 is now inserted
Enter the body of rod 1, then discharge pressure strip 8, pressure strip 8 is moved in the presence of spring 10 to the direction for skidding off accommodating chamber 11, but by
The body of rod 1 is inserted into the second through hole 16, pressure strip 8 cannot eject accommodating chamber 11, in the presence of spring 10, the second through hole 16
The second interior internal thread 15 is engaged with the external screw thread 4 on the body of rod 1, while in the presence of spring 10, the body of rod 1 is also pressed on
In first through hole 5, it is engaged with the first internal thread 6 in first through hole 5.When needing to adjust the position of limiter 3, need to only turn
Lever body 1, when the position of quick regulation limiter 3 is needed, firmly pressing pressure strip 8 makes the second through hole 16 and first logical
The axis collinear of hole 5, now the just position of freely adjustable limiter 3, unclamps pressure strip 8 after adjusting.
Structure according to above-mentioned implementation method is it is understood that when the body of rod 1 is taken out from the through hole 16 of first through hole 5 and second
After going out, pressure strip 8 loses constraint in the presence of spring 10, can eject accommodating chamber 11, is easily lost, and is not easy to preserve, and is
The problem is solved, in a kind of optional implementation method, also including guide spiro rod 9, pressure strip 8 is provided with 2 pilot holes 13,
2 pilot holes 13 are separately positioned on the both sides of the second through hole 16, and one piece of baffle plate 14 with through hole is equipped with 2 pilot holes 13,
Spring 10 is 2, and one end of spring 10 is abutted against with the baffle plate 14 with through hole, and the other end is abutted against with the inwall of accommodating chamber 11,2
Be equipped with a guide spiro rod 9 in individual pilot hole 13, guide spiro rod 9 sequentially pass through after baffle plate 14 and spring 10 with through hole with appearance
The inwall in chamber 11 received is spirally connected.Pass through 2 guide spiro rods 9 and baffle plate after the body of rod 1 is extracted out from the through hole 16 of first through hole 5 and second
14 cooperation, realizes to the spacing of pressure strip 8, prevents pressure strip 8 from ejecting accommodating chamber 11.It will be appreciated by those skilled in the art that
It is that the program is only one of which alternative, in order to reach the purpose of spacing pressure strip 8, can also uses other schemes, for example
Using spacing hole and the scheme of spacing lever.
In order to ensure the precision of adjustment, the pitch of the pitch of the first internal thread 6 and external screw thread 4 is generally designed as 0.5mm-
1.5mm, preferably 1mm.And for the ease of the Real Time Observation body of rod 1 into the length of human body, set on the outer wall of the whole body of rod 1
Scale, and the top of sawtooth 2 is " 0 " scale of scale.It will be appreciated by persons skilled in the art that being adjusted for the ease of observation
Distance value, in addition to scale is set on the outer wall in the body of rod 1, it would however also be possible to employ every 3mm or 4mm, a piece side for mark line is set
