Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.

As Figure 1-3, shoulder dresser comprises handle 1 and finishing knife.Finishing knife is by handle of a knife 4, cutter head 6 and to connect the segmental arc I 5 of handle of a knife 4 and cutter head 6 one-body molded.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 be 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.Each of the square inwall of handle of a knife installing hole 2 is all arranged and the circular hole 3 of draw-in groove 9 correspondence, circular hole 3 laterally runs through handle of a knife installation hole wall.A positioner is all set in each circular hole 3, positioner comprises spheroid 8, spring 7 and plug 10, what circular hole 3 formed near one end of inwall that a diameter is less than spheroid 8 diameter reduces mouth, the inwall of circular hole 3 is near arranged outside female thread, first spheroid 8 and spring 7 are put into circular hole successively, then screw in circular hole 3 by plug 10, 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 can not stablize fixing handle of a knife 4 time, plug 10 can be screwed out, change spring, such handle can Reusability.The cutter head of finishing knife in use easily weares and teares, and can realize a replacing finishing knife and need not discard whole shoulder dresser, both saved material by the positioner arranged, and operation is simple to change finishing knife.Also the finishing knife of different model can be changed by positioner.One end of segmental arc I 5 and the lower end one of handle of a knife 4, the other end of segmental arc I and cutter head 6 one, cutter head 6 is 80 ° ~ 100 ° with the angle of handle of a knife 4.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 cylindrical of diameter 1.0mm ~ 2.5mm, more than combination arranges and can be stably fixed in handle of a knife installing hole 2 by handle of a knife 4 on the one hand, the cylindrical handle of a knife 4 that avoids that on the other hand hypomere of handle of a knife 4 is set to diameter 1.0mm ~ 2.5mm 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 arranging circular hole 3 is four.The epimere of handle of a knife 4 is setting up and down arranges two draw-in grooves arranged 9 corresponding to circular hole 3 with two in handle of a knife installing hole 2, and often arranging draw-in groove 9 is four.More than combine setting, the direction of finishing knife can either be adjusted, more firmly can fix finishing knife again, and then avoid finishing knife in use to exit from handle of a knife installing hole 2.

What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
