Description
Technical field
The utility model is related to a kind of clamping device, the set type clamper of specifically a kind of quick needle changer.
Background technology
Car pin is the consumptive material class apparatus of surgeon dentist, is a very tiny draw point, and this root pin is by syringe needle and needle handle
Composition, can be inserted into and used on low speed mobile phone high, help surgeon dentist to open dental cavity and repair tooth.Car pin, be divided into wolfram steel car pin and
Diamond dust car pin.Wherein wolfram steel car pin is domestic abroad using more universal, the predominantly diamond dust car pin that dentist uses.Car
Pin is using certain hour needs to be changed, and people are that car pin is changed using quick needle changer, quick needle exchange
The use of device brings conveniently for doctor, but the clamping device of existing quick needle changer folder needle force is too low, easily triggers safety
Accident, causes flying needle and sliding pin phenomenon, and these are all for user brings inconvenience.
Utility model content
The purpose of this utility model is the set type clamper for providing a kind of quick needle changer, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the utility model provides following technical scheme：
A kind of set type clamper of quick needle changer, including body and inner ring, the body is using cavity mechanism and interior
On the inner surface of body, the angle that opening is arranged between the lower end of body and opening and body is 30-60 degree to ring set, this
Body and inner ring are made using 420 stainless steel materials, and the external diameter of body is 2.45-2.5mm, and length is provided with body for 2mm
Clamping position and clamp the internal diameter of position for 1.4-1.6mm, the width of opening is 0.25mm.
As further program of the utility model：Body and inner ring are adopted using annealing process and body and inner ring
Core machine is walked with CNC high accuracy to be processed.
As further program of the utility model：Inner ring is fixed on body internal surface, body using laser welding technology
Height be 7.45mm.
Compared with prior art, the beneficial effects of the utility model are：The product design is reasonable, simple structure, small volume,
It is lightweight, it is easy to receive and transports；Fault rate is low, and safety in utilization is good, and the product is using 420 stainless steels and high by CNC
Precision is walked core machining and is heat-treated, and long service life has carried out angle treatment at opening, can more preferably be pressed with V-type and is socketed
Touch and more laborsaving, it is operationally reached the state that high chucking power and anti-pinch make, prevent the product of flying needle and sliding pin phenomenon
Raw, using effect is good.
Brief description of the drawings
Fig. 1 is the front view of the set type clamper of quick needle changer.
Fig. 2 is the upward view of the set type clamper of quick needle changer.
Wherein：1- bodies, 2- openings, 3- inner ring.
Specific embodiment
The technical scheme of this patent is described in more detail with reference to specific embodiment.
Fig. 1-2, a kind of set type clamper of quick needle changer, including body 1 and inner ring 3 are referred to, the body 1 is used
Cavity mechanism and inner ring 3 is enclosed within the inner surface of body 1, opening 2 be arranged on the lower end of body 1 and be open 2 with body 1 it
Between angle be 30-60 degree, body 1 and inner ring 3 are made using 420 stainless steel materials, and the external diameter of body 1 is 2.45-
2.5mm, is provided with clamping position that length is 2mm and clamps the internal diameter of position for 1.4-1.6mm in body, 2 width of being open is
0.25mm.Body 1 and inner ring 3 are walked core machine and are added using annealing process and body 1 and inner ring 3 using CNC high accuracy
Work.Inner ring 3 is fixed on the inner surface of body 1 using laser welding technology, and the height of body 1 is 7.45mm.
Operation principle of the present utility model is：The all parts of the product walk core and machine accessory again by CNC high accuracy
By the heat treatment of rational hardness, then a product is formed by laser welding technology, angle treatment has been carried out at opening 2, can
More preferably to be contacted and more laborsaving with V-type press sleeve, it is set operationally to reach the state that high chucking power and anti-pinch make.
Rationally, simple structure, small volume is lightweight, is easy to receive and transports for the product design；Fault rate is low, uses peace
Good perfection, the product is walked core machining and is heat-treated, long service life, opening using 420 stainless steels and by CNC high accuracy
Angle treatment is carried out at 2, more preferably can have been contacted and more laborsaving with V-type press sleeve, it is operationally reached clamping high
The state that power and anti-pinch make, prevents the generation of flying needle and sliding pin phenomenon, and using effect is good.
The better embodiment to this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
Formula, in the ken that one skilled in the relevant art possesses, can also be on the premise of this patent objective not be departed from
Various changes can be made.
