Abstract
The invention relates to a molar handset bearing dismantling puller, belonging to the medical apparatus and instruments. The puller comprises a frame body, a shaft lever and a push rod, wherein, the frame body is equipped with a hole; the shaft lever is in a hollow shape, forms a through hole in a penetration manner and can reciprocate in the hole, and one end surface of the shaft lever is equipped with at least one split; when the shaft lever reciprocates in the hole, the split shows change of enlargement and reduction caused by oppression of the inner wall surface of the hole; the split can clamp a bearing, and the push rod can reciprocate in the through hole; and while pulling out the bearing, axial components can be pushed by the shaft lever after clamping and fixing the bearing via the split, thus the bearing can be easily and conveniently removed.
Description
Technical field
The present invention and medical mechanical domain, particularly a kind of molar handset bearing dismantling puller refers to a kind of molar handset bearing dismantling puller that can fast, conveniently take off the bearing of molar handset especially.
Background technology
Odontologist is when work, usually need very wholwe-hearted will and careful attitude, and also need suitable skill and degree of accuracy, and medical treatment when action for the patient being ground one's teeth in sleep or boring tooth, just need a kind ofly be called the medical device of molar handset, in recent years along with the progress of science and technology, in this kind medical science equipment, significant progress has been arranged in stability, the motor rotary speed of machinery.
And when odontologist when undergoing surgery, usually all need take one to observe the reflecting mirror of usefulness and molar handset undergoing surgery, and utilize an external light source to shine patient's inside, oral cavity again, so, promptly can utilize molar handset to come the patient is undergone surgery.And molar handset is one to have the machinery of high-speed motor, odontologist all utilize the high speed rotating of this molar handset air turbine come to patient's tooth grind one's teeth in sleep, operation such as plastotype.
Yet above-mentioned molar handset still exists following point to wait to improve when using:
Because molar handset comprises a high speed air turbine, when air turbine is rotated, inner bearing stability is just quite important, because the lifting of existing air turbine rotating speed, bearing under high speed rotating, usually damage easily, and bearing and axle center are formed mutually, common people also can't take out bearing changing, and the technology of existing replacing bearing has the not high problem of yield, and necessity of improvement is arranged in fact.
Summary of the invention
The object of the present invention is to provide a kind of molar handset bearing dismantling puller, solve the problem of changing the bearing difficulty.
A kind of molar handset bearing dismantling puller can be for the bearing of the default molar handset of choosing, and described puller comprises:
One support body offers a hole;
One axostylus axostyle, can be for moving back and forth in this hole, this axostylus axostyle is hollow form and runs through formation one perforation, this axostylus axostyle one end face is offered at least one breach, in the time of in this axostylus axostyle moves back and forth in this hole, this breach can present the variation of amplifying and dwindling by the internal face compressing of this hole, and this breach can supply this bearing of clamping;
One push rod can be for moving back and forth in this perforation.
Wherein this axostylus axostyle moves back and forth in this hole in screw thread turn mode;
Wherein this push rod moves back and forth in this perforation in screw thread turn mode;
Wherein this push rod one end forms a rotating part;
This support body fixed mount that locks wherein;
Wherein this axostylus axostyle thread locking is in a fast pulley.
The invention has the advantages that: when having improved the damage of bearings of existing molar handset, must put in order group and abandon wasting problem, use the present invention can easily, simply change the bearing of molar handset voluntarily, have cost-effective practical improvement.
Description of drawings
Fig. 1 is the axonometric chart of preferred embodiment of the present invention.
Fig. 2 is the three-dimensional exploded view of preferred embodiment of the present invention.
Fig. 3 is the enforcement sketch map one of preferred embodiment of the present invention.
Fig. 4 is the enforcement sketch map two of preferred embodiment of the present invention.
Fig. 5 is the enforcement sketch map three of preferred embodiment of the present invention.
The specific embodiment
With shown in the accompanying drawing 2, be the axonometric chart and the three-dimensional exploded view of preferred embodiment of the present invention as accompanying drawing 1, find out that by knowing among the figure puller 1 of the present invention comprises:
Wherein, these axostylus axostyle 3 first thread lockings are in a fast pulley 23, move back and forth in this hole 21 in screw thread turn mode again, preferred embodiment is surrounded with screw thread for these axostylus axostyle 3 outside wall surface, and hole 21 internal faces of this support body 2 are provided with screw thread equally, this push rod 4 moves back and forth in this perforation 31 in screw thread turn mode, and preferred embodiment is surrounded with screw thread for these push rod 4 outside wall surface, and perforation 31 internal faces of this axostylus axostyle 3 are provided with screw thread equally.
By above-mentioned structure, form design, be described as follows with regard to use situation of the present invention, as accompanying drawing 2 to shown in the accompanying drawing 5, for three-dimensional exploded view, the enforcement sketch map one to three of preferred embodiment of the present invention, find out by knowing among the figure, because axle center member 6 is an one with 5 groups of structures of bearing, and molar handset is when using, usually all be that bearing 5 is easier to damage, thus promptly can utilize the present invention that the bearing 5 that damages is taken off, with the bearing 5 that more renews; And when desiring to carry out the choosing during operation of bearing 5, as long as the bearing 5 of axle center member 6 is aimed at, rotating this axostylus axostyle 3 again makes axostylus axostyle 3 can move back and forth in this hole 21, at this moment, in axostylus axostyle 3 one end faces one breach 32 is set by this, this breach 32 promptly can present the variation of amplifying and dwindling because of the internal face compressing of this hole 21, adjusting suitable breach 32 sizes again makes this breach 32 can effectively grip this bearing 5, after confirming that bearing 5 has effectively been gripped by breach 32, promptly can rotate this push rod 4 makes push rod 4 move back and forth in this perforation 31, moving this push rod 4 again makes push rod 4 push these axle center members 6, to make this axle center member 6 leave this bearing 5, so, promptly finish the action of choosing of bearing 5.By said structure and action, the present invention can take off easily, easily with axle center member 6 and be the bearing 5 of one, when the bearing 5 of molar handset damages, will not put in order group axle center member 6 whole abandoning, after can utilizing the present invention earlier bearing 5 to be taken off, the bearing 5 that more renews gets final product, and the present invention has cost-effective practical progress and exists.
