Side is resisted against on the cell wall of 64 groove 642 of force-applying piece, can limit force-applying piece 64 by the resilient force of elastic component 62 to separate
The direction of shoulder 24 is mobile, and elastic component 62 can be allowed to have initial compression amount, applies a pretightning force to force-applying piece 64.As
In addition limitation force-applying piece 64 can also be arranged to the limit mobile far from 24 direction of shoulder in a kind of change mode on tube body 22
Bit architecture.
Under non-working condition, under the action of force application mechanism 6, the second clamping head 84 makes it close to the first clamping head 82
The accommodation space 88 that upper opposite holding tank 86 is formed is less than the size of the grip part of root canal file.When work, towards the side of neck 4
To the press section 92 for pushing release member 9, so that the elastic component 62 of force application mechanism 6 is compressed, the second clamping head 84 is to far from first
The direction of clamping head 82 is mobile, and the accommodation space 88 for forming holding tank 86 opposite thereon is greater than the big of the grip part of root canal file
It is small, then the grip part of root canal file is put into accommodation space 88, unclamps the press section 92 of release member 9, the promotion of elastic component 62 is applied
Power part 64 drives connecting rod 66 to haul the second clamping head 84 to the movement of the direction of the first clamping head 82, to clamp holding for root canal file
Hold portion.When unloading root canal file, the press section 92 of release member 9 is pushed towards the direction of neck 4, so that the elastic component of force application mechanism 6
62 are compressed, and the second clamping head 84 is mobile to the direction far from the first clamping head 82, release the chucking power of clamping part 8, and make
The accommodation space 88 that opposite holding tank 86 is formed thereon is greater than the size of the grip part of root canal file, then by the gripping of root canal file
It is taken out from accommodation space 88 in portion.
Root canal file clamper of the present invention is that clinical common root canal file specially designs, for replacing the fingerhold root canal of doctor
File clamps stable, good operability, and root canal file will not be rotated, be swung after clamping root canal file；Neck is tiny, and it is very big to leave doctor for
The visual field be observed that root canal orifice, more easily root canal file is put into root canal；It is separated with root canal file simply, thumb pushes
Press section can be separated with root canal file on shank, Dentist can be allowed to continue to use finger clamp after root canal file finds root canal orifice
It holds root canal file and carries out the unobstructed of root canal, accomplish the seamless link of medical procedure.The present invention is suitable for clinic and commonly uses various root canal files,
Need not mating dedicated root canal file, Clinical practicability is extensive, it may also be used for the simple root canal of new hand doctor is got started study, it can also be used to
Root canal orifice detects, is unobstructed under micro- root canal.
In conclusion root canal file holder structure of the present invention is simple, clamping is stablized, easy to operate, is conducive to treatment, applicability
Extensively.
The above for those of ordinary skill in the art can according to the technique and scheme of the present invention and technology
Other various corresponding changes and modifications are made in design, and all these change and modification all should belong to the claims in the present invention
Protection scope.
