With reference to accompanying drawing 1-11: elastic frame (2) is by last plate-girder (7), the integral, flexible structure that following plate-girder (6) and both sides side plate (8) are formed.Side plate (8) tail end is cantilever-shaped, makes plate-girder have elasticity.There is a concave step at the leading edge middle part of following plate-girder (6), flat board by inclined-plane and trailing edge links, on the inclined-plane, have the jaw patchhole (9) of two abnormity, and between two holes (9), being provided with two flechette-type grooves (10), hole (9) and groove (10) aim at installs jaw type handle or the design of V shape resilient handle.

Have two at the middle part on inclined-plane and play tongue locating holes (11), and between two holes, be provided with one and play tongue and push against groove (13), design for the original bullet tongue forceps of " lucky " board shaver formula handle is installed.

Near the place of biside plate (8) two inclined-planes (12) that gradient is very little are arranged in the leading edge of following plate-girder (6), its effect is to make can stablize behind blade bearing (1) the wedging elastic frame (2) to be difficult for withdrawing from.If when product was non-dismounting type, the gradient on this inclined-plane can strengthen, (also can be designed to step) can not extract after making the blade bearing wedging.

Last plate-girder (7) has a boss (14) to be used for compressing cutter, and can increase the rigidity that goes up plate-girder.Thickness and gradient after the opening retaining and gradient and should fold with blade bearing (1) between the upper and lower plate-girder (6,7) match.

With reference to accompanying drawing 12-16: blade bearing (1) is by blade bearing base plate (15), chip guiding grid (16) cutter pressing plate (17), and preceding hinge (22) and back hinge compositions such as (25).

The middle part of blade bearing base plate (15) has bottom knife chip area (19) and the space (20) that handle stayed is installed.Respectively there is a small boss (21) both sides of leading edge (18), are the usefulness of bottom knife location.

Chip guiding grid (16) gradient is 1:10, and microcephaly's thickness is 0.6mm.It with inclined-plane that bottom knife contacts on, have several half garden shape grooves (23), the glazing bar between the groove (24) is streamlined, in order to dust lead.Boss (26) and boss (27) (seeing accompanying drawing 14) are that cutter is played the role of positioning.By hinge (22) chip guiding grid (16) upset is pressed on the bottom knife.

Cutter pressing plate (17) is a shape thin slice, is pressed on the cutter by hinge (25) upset.

The position of hinge (22) also can be omited shown in Figure 15,16 and be moved backward, can improve the rigidity of chip guiding grid like this.

During the blades seat, with reference to Fig. 4, earlier a blade is placed on the blade bearing base plate (15), cutting edge is pressed in chip guiding grid (16) upset on the blade then towards small boss (21), and at this moment, blade just is positioned at (being bottom knife) between chip guiding grid and the base plate.Another blade is placed between boss (26) and the boss (27), cutting edge is pressed in pressing plate (17) upset on the blade then towards boss (26) again, and blade is promptly located (being cutter).

Distance between the upper and lower blade cutting edge behind the folding location is 0.7mm, and cutter is that 1.5mm(is that bottom knife exposes 1.5mm than cutter more with the potential difference of bottom knife).At this moment the gradient of blade bearing should be consistent with elastic frame, and thickness can be slightly larger than the retaining of opening between upper and lower plate-girder.Like this, behind blade bearing wedging elastic frame, just held very tight.

With reference to accompanying drawing 17,18: this is a kind of handle of integral, flexible structure.It is when the jaw hole (9) in the plate-girder (6) under the jaw insertion that the root of jaw (28) has its effect of an edge of a knife (30), the time, just enter in the flechette-type groove (10), and tool tip is locked in the elastic frame.The edge of a knife (30) is in the lowest part of flechette-type groove (10) at ordinary times, and when cutter head rotated with facial curve, the edge of a knife (30) moved to the higher position of flechette-type groove thereupon, and elastic nip this moment (28) is outer to be opened.When cutter head left face, jaw made the edge of a knife (30) return to the lowest part of flechette-type groove because elastic reaction inwardly clamps, and cutter head also just returns to operating position commonly used.

Handle bar (29) adopts two stem bar structures.Feather key (31) middle part is a voussoir, is embedded in the groove of handle bar (29).During use, jaw (28) is aimed at patchhole (9), pushing tow inwards, jaw promptly inserts and clamps cutter head.During dismounting, press feather key (31) downwards, handle can be pulled out when jaw opens with thumb.

With reference to accompanying drawing 19,20: this is a kind of V shape resilient handle.Bead (34) is arranged on the two ends of jaw (33).During use, jaw bead (34) is aimed at patchhole (9) inwardly advance, bead slided in being stuck in groove along hole slot and got final product (referring to accompanying drawing 3) this moment.At this moment blade bearing is locked in the elastic frame by it.When cutter head shakes along facial curve, the also corresponding rotation of bead, its angle can reach 40 °-45 °.During dismounting, as long as with the inside folder of jaw (33), bead (34) just outwards slides to the handle jaw and pulls out from the hole.

Embodiment 1: with reference to accompanying drawing 1-20: its structure as mentioned above.When using general double-edged razor blade, blade is fractureed into two blades by the dotted line position of Fig. 4, installation method as previously mentioned.

Embodiment 2: with reference to Figure 23: handle and elastic frame are made an integral body (being that handle is non-dismountable), and at this moment, the gradient on the inclined-plane (12) of the leading edge lower end of blade bearing and elastic frame leading edge both sides need strengthen, and make the blade bearing can be relatively stable.Other structure and handling method are with embodiment 1.

Embodiment 3: with reference to accompanying drawing 21-24: this is a kind of non-dismounting type (being narrow type) shaver cutter head.Basic structure is identical with embodiment 1, and difference is: 1, need to use special narrow blade, its size identical with " lucky " board blade (bottom knife 7 * 38, cutter 5.5 * 38).A locating notch (37) is just opened in this not punching of blade in the both sides of cutter.2, elastic frame and blade bearing are narrower.3, cancellation cutter pressing plate (7) and hinge (25) cooperate with it and increase locating piece (35) in the chip guiding grid both sides.4, because do not need removal of inserts, inclined-plane (12) gradient on blade bearing leading edge bottom and the elastic frame leading edge increases.5, the seal face shape of plate-girder blade changes to some extent on the elastic frame.By the improvement of above structure, can make blade bearing once pushing elastic frame, promptly can not extract.

The utility model can be changed a little to chip guiding grid, selects different blade location for use, and matches with different handle, can be combined into a series of products, thereby applicability is strong.Owing to adopted through type dust lead structure, the chip removal effect is greatly improved.Blade bearing adopts foldable structure, makes its mounting or dismounting easier.Be equipped with suitable handle again, more comfortable reliable when shaving.Again owing to can adopt common double-edged razor blade, thereby cost is low, is convenient to promote the use of.
