Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.

As Figure 1-3, shoulder dresser includes handle 1 and finishing knife.Finishing knife is one-body molded by the segmental arc I 5 of handle of a knife 4, cutter head 6 and connection handle of a knife 4 and cutter head 6.Handle 1 lower end arranges handle of a knife installing hole 2, and the upper end of handle of a knife 4 is inserted in handle of a knife installing hole 2, and the cross section of the epimere of handle of a knife 4 is square, and each of the square upper end of handle of a knife 4 arranges draw-in groove 9.Handle of a knife installing hole 2 cross section of handle 1 is square.Being respectively provided with on each of the square inwall of handle of a knife installing hole 2 and the circular hole 3 of draw-in groove 9 correspondence, circular hole 3 extends transversely through handle of a knife and installs hole wall.A positioner it is respectively provided with in each circular hole 3, positioner includes spheroid 8, spring 7 and plug 10, circular hole 3 forms a diameter and reduces mouth less than spheroid 8 diameter near one end of inwall, the inwall of circular hole 3 is near arranged outside female thread, first spheroid 8 and spring 7 being sequentially placed in circular hole, then screwed by plug 10 in circular hole 3, one end of spring 7 is pressed on plug 10, the other end of spring 7 is pressed on spheroid 8, and a part for spheroid 8 is stretched out and reduced mouth and be stuck in corresponding draw-in groove.Spring 7 extrudes spheroid 8, and spheroid 8 extrudes draw-in groove 9, and then is fixed in handle of a knife installing hole 2 by handle of a knife 4, such setting can spring 7 is impaired stably can not fix handle of a knife 4 time, it is possible to screw out plug 10, change spring, such handle can Reusability.The cutter head of finishing knife in use easily weares and teares, and is capable of a replacing finishing knife without discarded whole shoulder dresser by the positioner arranged, and had both saved material, and operation is simple to change finishing knife.Also the finishing knife of different model can be changed by positioner.The lower end one of one end of segmental arc I 5 and handle of a knife 4, the other end of segmental arc I and cutter head 6 one, the angle of cutter head 6 and handle of a knife 4 is 80 ° ~ 100 °.The outer tangent line of the other end of segmental arc I 5 and the angle of cutter head are 90 ° ~ 120 °.The length of cutter head 6 is set to 0.8mm ~ 1.2mm.The radius of segmental arc I 5 is 0.1mm ~ 0.15mm, and the blade of cutter head 6 is arranged downwards.

The hypomere of handle of a knife 4 is cylindrical, and the diameter of the hypomere of handle of a knife 4 is 1.0mm ~ 2.5mm.The epimere cross section of handle of a knife 4 is set to square, the hypomere of handle of a knife 4 is set to the cylinder of diameter 1.0mm ~ 2.5mm, combination of the above arranges and can be stably fixed in handle of a knife installing hole 2 by handle of a knife 4 on the one hand, on the other hand the hypomere of handle of a knife 4 is set to the cylinder of diameter 1.0mm ~ 2.5mm and avoids handle of a knife 4 and in use stimulates the oral cavity arriving patient, to the uncomfortable sensation of patient.

Two row's circular holes 3 setting up and down in handle of a knife installing hole 2, often row's circular hole 3 is four.The draw-in groove 9 of two rows that the epimere of handle of a knife 4 two row's circular holes 3 setting up and down and in handle of a knife installing hole 2 are corresponding, often arranging draw-in groove 9 is four.Combination of the above is arranged, and can either adjust the direction of finishing knife, finishing knife can be more firmly fixed again, and then avoids finishing knife in use to exit from handle of a knife installing hole 2.

What finally illustrate is, above example is only in order to illustrate the technical solution of the utility model and unrestricted, although this utility model being described in detail with reference to preferred embodiment, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent replacement, without deviating from objective and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
