Structure.
Background technique
The machine core clamp structure of dental high-speed cell phone be dental high-speed cell phone at work clamping trolley for patients teeth into
The component of the processes such as row brill, expansion, mill.The clamp structure of high speed handpiece currently on the market is nothing more than there are two types of: one is springs
Formula, a kind of no spring formula.Spring is divided into outer spring and two kinds of interior spring, and no spring formula is substantially all using KAVO house journal mistake
Structure after protection period, and it is high to heat treatment requirements without spring formula machine core, it otherwise will appear clamping piece fracture and flying needle phenomenon；Bullet
Spring formula machine core is at high cost, and difficulty of processing is big, and performance is unstable, it would be highly desirable to improve.
Utility model content
The purpose of this utility model is that in view of the drawbacks of the prior art and insufficient, provide that a kind of structure is simple, and design is closed
Reason, novel high speed handpiece machine core clamp structure easy to use, needle of more changing trains is convenient, clamping trolley needle secure, and performance is steady
It is fixed, the incidence of flying needle is reduced, practicability is stronger.
In order to achieve the above purposes, the technical solution adopted by the utility model is:, and it includes movable pressing sleeve, clamping piece, rotation
Mandrel；Wherein clamping piece is plugged in rotary core shaft, is in gap setting between clamping piece upper section outer wall and rotary core shaft inner wall, and
The axial line of clamping piece upper section deviates the axial line setting of rotary core shaft；The clamping piece upper section is equipped with movable pressing sleeve, and
Movable pressing sleeve activity is fastened on upper end in rotary core shaft；The internal taper hole lower edge activity of the movable pressing sleeve lower end, which is embedded, is pressing from both sides
In gap between the tapered surface and rotary core shaft inner wall of gripping member upper end.
Further, the upper section of the clamping piece and the junction of lower section offer gap.
Further, the deviation angle that the axial line of the clamping piece upper section deviates the axial line of rotary core shaft is greater than 0 °
And less than 5 °.
Working principle of the utility model is: its axial line of the retained part of clamping piece upper section and the axial line of rotary core shaft are in
One angle tilt after the internal taper hole of movable pressing sleeve and the taper face contact of clamping piece upper end, makes to press from both sides when pressing activity pressing sleeve
The tilt angle of gripping member upper section is zeroed, i.e., the axial line of clamping piece upper section is overlapped with the axial line of rotary core shaft, is inserted into dentistry vehicle
Needle；After the pressing sleeve of release activity at this time, the consistency and elasticity of clamping piece itself can be restored to the position before installation dental sewing machine needle, right
A radial force is given in the side of dental sewing machine needle, and dental sewing machine needle upper section size is consistent with movable pressing sleeve inner hole, and clamping piece lower section
Size is also consistent with dental sewing machine needle size, then firmly clamps dental sewing machine needle；By pressing activity pressing sleeve, make clamping piece upper section with
Rotary core shaft axial line is overlapped, then can replace dental sewing machine needle.
After adopting the above structure, the utility model has the beneficial effect that a kind of high speed handpiece machine core described in the utility model
Clamp structure, needle of more changing trains is convenient, clamping trolley needle secure, and performance is stablized, and the incidence of flying needle is reduced, and practicability is stronger,
The advantages that the utility model has structure simple, and setting is reasonable, low manufacture cost.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the utility model installation dental sewing machine needle.
Description of symbols:
Movable pressing sleeve 1, clamping piece 2, gap 2-1, rotary core shaft 3, dental sewing machine needle 4.
Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
Referring to as depicted in figs. 1 and 2, present embodiment the technical solution adopted is that: it includes movable pressing sleeve 1, folder
Gripping member 2, rotary core shaft 3；Wherein clamping piece 2 is plugged in rotary core shaft 3,2 upper section outer wall of clamping piece and 3 inner wall of rotary core shaft it
Between be in gap setting, and 2 upper section of clamping piece axial line deviate rotary core shaft 3 axial line setting；On the clamping piece 2
Section is equipped with movable pressing sleeve 1, and movable 1 activity of pressing sleeve is fastened on upper end in rotary core shaft 3；1 lower end of movable pressing sleeve it is interior
Taper hole lower edge activity is embedded in the gap between 3 inner wall of tapered surface and rotary core shaft of 2 upper end of clamping piece；Movable pressing sleeve 1
Internal diameter and 4 upper section major diameter fit of dental sewing machine needle be arranged, the major diameter fit of the lower section internal diameter of clamping piece 2 and dental sewing machine needle 4 is arranged.
Further, the upper section of clamping piece 2 and the junction of lower section offer gap 2-1, are 2 upper section of clamping piece
The deviation of axial line provides certain rebound and deviates nargin.
