Distance significantly saws bone, this exists there have been scroll saw length and the unmatched situation of service condition and use inconvenience
The shortcomings that.
Summary of the invention
The purpose of the utility model is to provide a kind of orthopaedics scroll saws.It is easy to use that it has the advantages that length can reconcile.
The technical solution of the utility model includes: a kind of orthopaedics scroll saw, including handle one, the connection protection of handle one is first, protection
The head end of first connection saw blade, the tail end of saw blade are set in collector after sequentially passing through protection head two and handle two；The protection
First two are equipped with bolt；The collector is connect by mounting bar with handle two；The collector includes shell, the middle part of shell
Equipped with installation axle, one end of installation axle and clockwork spring is connected, and the other end of clockwork spring and the tail end of saw blade connect；It is described outer
Shell is equipped with saw blade mouth.
In orthopaedics scroll saw above-mentioned, the respective left and right part of the handle one and handle two is respectively equipped with a finger slot.
In orthopaedics scroll saw above-mentioned, roller bearing is equipped with by the saw blade mouth.
In orthopaedics scroll saw above-mentioned, the inside of the protection head two is equipped with groove.
The utility model has the beneficial effects that compared with prior art, when the utility model is used, by unscrewing bolt,
Collector can back store its external saw blade, shorten the length of external saw blade, can also be manually by saw blade from collector
It pulls out, increases the length of external saw blade, then bolt is screwed to the fixation that can be realized to length of saw blade, so the utility model
Have the advantages that length of saw blade is adjustable, it is easy to adjust, and the saw blade of appropriate length is selected, scroll saw is more convenient to use；This
Utility model is provided with finger slot on handle, pulls saw blade back and forth convenient for doctor；The utility model is provided with rolling in collector
Axis is not in the case where blocking when adjusting length of saw blade, easy to use；The utility model is provided in protection head two
Groove, such bolt is in fixed saw blade, the case where being not in loosening, highly reliable.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
Embodiment.A kind of orthopaedics scroll saw is constituted as shown in Figs. 1-5, including handle 1, the connection of handle 1 protection first 2,
The head end of first 2 connection saw blade 3 is protected, the tail end of saw blade 3 is set to collector 6 after sequentially passing through protection head 24 and handle 25
In；The protection head 24 is equipped with bolt 7；The collector 6 is connect by mounting bar 8 with handle 25；The collector 6 wraps
Include shell 9, the middle part of shell 9 is equipped with installation axle 10, and installation axle 10 is connect with one end of clockwork spring 11, clockwork spring 11 it is another
One end is connect with the tail end of saw blade 3；The shell 9 is equipped with saw blade mouth 12.
The application method of the utility model is with working principle: the application method of the utility model is similar with conventional scroll saw, doctor
Raw both hands hold handle 1 and handle 25 respectively can carry out the operation of sawing bone, protection first 2 and protection head with saw blade 3
24 can protect doctor is hurt by saw blade 3, because the tail end of saw blade 3 sequentially passes through protection head 24 and handle 25, so protection head
24 and handle 25 in necessarily be equipped with saw blade channel passed through for saw blade 3, bolt 7 by screw thread with protect head two connect, pass through rotation
Turning bolt 7 may be implemented the effect of elastic saw blade 3, and collector 6 has the function of recycling saw blade 3, structural principle class always
It is similar to tape measure.The effect of 6 specific structure of collector is: having the clockwork spring 11 in tensional state, does resetting movement, always to saw
Item 3 applies the power of recycling, that is, has the effect of saw blade 3 being retracted into shell 9.In this way before using this scroll saw, it can carry out outer
The length of portion's saw blade 3 is adjusted, and unscrews bolt 7, and saw blade 3 can be retracted into shell 9 by collector 6, it can shorten protection first 2
The length of saw blade 3, the saw blade 3 of collector 6 can also be pulled out between protection head 24, increase protection first 2 and protection head two
The distance of saw blade 3 between 4 screws in bolt 7 in the length of suitable saw blade 3, fixes saw blade 3, i.e. screw-in bolt 7
To protect first 2 and the relative position of saw blade 3 fix.
The respective left and right part of the handle 1 and handle 25 is respectively equipped with a finger slot 13.Refer to that slot 13 meets anthroposomatology,
Pull saw blade 3 back and forth convenient for doctor.
Roller bearing 14 is equipped with by the saw blade mouth 12.When saw blade 3 is stretched out from saw blade mouth 12, rotatable roller bearing can be bypassed
14, it is flexible in collector 6 that this design can be conducive to saw blade 3.
The inside of the protection head 24 is equipped with groove 15.Saw blade 3 is against at groove 15 and fixes by bolt 7, fixed effect
More preferably.
