Abstract

The utility model provides a spiral tool for grinding and cutting nail clippers, the grind of the spiral tool for grinding and cutting nail clippers is continuous and stable, and grind effect is good. A plurality of spiral blade teeth are arranged on the peripheral surface of the work piece section of a rod-shaped tool, and a shaft lever section and a connecting section which are inserted and fastened with a supporting frame are extended onto both sides of axial direction of the work piece section of the rod-shaped tool; the helix angle W of the blade tooth is selected between 20DEG to 45DEG, the tooth number is between 10 and 30, both side faces of the blade tooth are provided with inclined planes to form triangular tooth shapes, and the inclined direction of the triangular tooth shape which is the same as the rotary direction is a clockwise direction; when a cone-shaped tool is used, the diameter ratio between a big cone point and a small cone point is between one to one and three to one, and the blade tooth shallows gradually from the big cone point to the small cone point along the axial direction.

Description

Spiral nail mill cutting knife tool

The utility model relates to a kind of tourism and small stores, particularly a kind of in the electrodynamic type nail grinds scissors device employed spiral nail mill cutting knife tool.

A kind of nail mill cutting knife tool is disclosed in 93203532.9 patent formerly, this cutter is an isodiametric cylinder, offer some longitudinal grooves and form straight-tooth shape structure in the cylinder periphery, when rotated, the very little straight-tooth generating gear of space width that it is long as same axial length, under this profile of tooth effect, the mill of nail cut be interrupted, discontinuous, nail mill cut formed convex-concave between main dependence tooth and the tooth partly carries out, the file wheel of its effect as same rotation, and there is not any rotary-cut effect, therefore, with nail by in the mill process, its grinding process also is to be interrupted and discontinuous, easily produce and beat, the nail mill tangent plane that grinds is not very smooth.And nail skiving face is wanted the normal tool axis line, so not so good behaviour holds.Slide especially easily and injure skin and flesh partially.

The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of prior art, and provide a kind of have screw serrated form, mill cuts continuously, stable, efficient is high, the measured spiral nail mill cutting knife tool of matter.

The purpose of this utility model is to realize by following technical scheme:

Workpiece section outer surface at a rhabodoid cutter offers some helical form sword teeth, the axial both sides of rod cutter workpiece section are extended with and support live the mutually shaft section and the linkage section of plug-in card, the helical angle W of sword tooth selects between 45 degree at 20 degree, the number of teeth is between 10 to 30, the two sides of sword tooth are the inclined-plane and constitute the triangle profile of tooth, the inclination trend of triangle profile of tooth is the clockwise direction identical with rotation direction, when adopting the taper cutter, the diameter of its large awl end and conelet end is than between 1.1: 1 to 3: 1, the sword tooth is by large awl end to the conelet end vertically by deeply gradually shallow variation, forms the revolution working face with continuous rotary-cut effect when rotary work.

Therefore: remarkable result of the present utility model is:

The the 1st: owing to adopt screw type sword tooth, thereby form a kind of file wheel that had both had circumferential burnishing action when making the cutter rotational workpieces, have revolving vertically of similar drill bit again and rise the mill effect of cutting, especially it has a plurality of sword teeth simultaneously at the mill that touches that carries out with nail, so, that mill is cut is stable, do not have continuously and beat and contact sense, and the nail surface after its mill is cut is smooth, smooth and do not have and connect the tool marks mark.

The the 2nd: because each helical edges tooth has certain circumferential rotary-cut angle B again, therefore, when rotary work, the rigid of no straight-tooth knocked the mill sense, but a kind of scraped finish sense, thereby, it has good scraped finish efficient and planarization, and have along the traction of helical angle W direction, so its mill does not have the vestige when handing over cutter when cutting.

The 3rd: when adopting the taper work section, it is tiny and be easy to visit and reach the advantage that the pedicure of cutting is ground at place, toenail both sides of the edge also to have a front end.

Concrete structure of the present utility model is realized by the following examples and accompanying drawing:

Fig. 1 is a structure chart of the present utility model.

Fig. 2 is that the A of Fig. 1 is to view.

Fig. 3 is that the B of Fig. 1 is to view.

Fig. 4 is the structure chart of another embodiment of the present utility model.

Below in conjunction with accompanying drawing 1-4 concrete structure of the present utility model is described in detail:

The utility model is one to offer the emery wheel of sword tooth 111, the axial two ends of emery wheel 1 active section have protruded out plug-in

card section

12 and 13, it is characterized in that: the sword tooth 111 on the active section 11 of emery wheel 1 is helical form sword tooth, the lead angle W of helical form sword tooth is between 20 degree are spent to 45, the both sides 1111 of each helical form sword tooth are the inclined plane and are along circumferential clockwise inclination that the number of teeth of helical form sword tooth is between 10 to 30.Referring to Fig. 1 and Fig. 2.

Architectural feature of the present utility model also is:

Emery wheel 1 with helical form sword tooth is the frustum structure, its large awl end and conelet end diameter are than between 1.1: 1 to 2: 1, be shape variation from deep to shallow from large awl end to the tooth depth of the helical edges tooth of conelet extreme direction extension, between 35 degree, the number of teeth is between 13 to 20 at 25 degree for lead angle W.Referring to Fig. 1 to Fig. 3.Large awl end and conelet end diameter are than between 1.2: 1 to 1.8: 1, and the tooth pitch included angle B between the adjacent helical edges tooth is at 30 to 70 degree, and each helical edges tooth is a right-handed thread, sword tooth incline direction with turn to cross section also triangular in shape in the same way.Referring to Fig. 2 and Fig. 3.

The active section of mill cutting knife tool of the present utility model can be the cylindrical structural that has the helical edges tooth, promptly as shown in Figure 4, because also can reach the effect of being cut by multiple tooth mill of flour milling while at cylinder table helical edges tooth together with nail.

As adopt the conical workpieces section, then possessing under the above-mentioned multiple tooth preceding topic that contacts continuous workpiece simultaneously, has the rotary-cut effect that better axially promotes reach, there is an axial thrust load on the inclined-plane that causes because of tapering to nail, this component can have nail axially to lead at circumferential mill and pushes away effect when cutting, so have the mill cut channel mark that does not have transposition, and, have very fast mill and cut effect.Another advantage is exactly that its front end is thin and be easier to be insinuated into and be difficult for the nail marginal position that mill cuts and carry out reconditioning.
