Description

Hair scissors with limiting comb regulating device

Technical field

The utility model relates to hair scissors more particularly to a kind of hair scissors with limiting comb regulating device.

Background technique

Existing hair scissors, whether barber shop's use or household, want the hair for cutting certain length, are all to pass through hair scissors On limiting comb realize that general hair scissors can all match different types of limiting comb, to meet different human needs；People need More close haircuts are cut, certain limiting comb is just changed, but for household, people cut on earth to be different limiting combs Mostly short hair has no concept, accordingly, it sometimes is necessary to try down, or is commonly used, and can just have to the length of limiting comb certain Understand.

Summary of the invention

Based on the above issues, the purpose of the utility model is to provide a kind of hair scissors with limiting comb regulating device, one A hair scissors is not necessarily to prepare multiple limiting combs, and required hair lengths are just adjusted by the limiting comb being mounted on hair scissors, The production accessory of hair scissors, save the cost can be reduced；

The technical solution adopted in the utility model is as follows, the hair scissors with limiting comb regulating device, including limiting comb, tune It saves frame, adjust ring and knob；Limiting comb is mounted at Hair scissor head, and limiting comb is equipped with two branch angles, and the one end at branch angle is opened There is round mouth；Adjusting bracket is in H-type, and centre is semicircle bulge loop；An adjustable column is fixed on bulge loop；The both ends of adjusting bracket are fixed with connection It detains, the round mouth on branch angle sticks into connection buckle, so that it may which limiting comb and adjusting bracket are connected to a fixed；It adjusts ring and is mounted on adjusting bracket On, it adjusts ring and is connected with knob；It adjusts ring and is equipped with helical ring, adjustable column is moved along helical ring.

Knob surface is uniformly covered with convex block.

Helical ring difference in height is 3 centimetres.

Assuming that Fig. 3 our adjustable column 1, his motion track is Z1.......ZN, then we only need to control spiral The screw pitch h and helixangleβ of line 2 can realize that the motion track to adjustable column 1 controls.

The utility model utilizes the principle of circular helix, and the parametric equation of circular helix is: x=acos θ, y= Asin θ,In formula: θ=ω t, ω are angular speed, and h is known as screw pitch, and β is known as spiral Angle takes positive sign to right-hand helix in formula, takes negative sign to left helix.If using arc length s as parameter, equation are as follows:Determine that three of a circular helix want substantially Element is: diameter D, lead H and the rotation direction of circular helix；In a lead, the length of helix is

The parametric equation of known circular helixWhen we need budget Z's When numerical value, that is, when needing the position of positioning limit comb, it is only necessary to pass through and change screw pitch h, helixangleβ；Tune on adjusting bracket Movement of the segmented column on adjusting ring on helical ring, by adjusting the logical relation on ring between helical ring, i.e. knob rotation is adjusted When ring, it is mobile in X-axis horizontal direction that adjustable column will be with helical ring, so that it may realize that hair scissors when in use, retains hair Length；The utility model structure is simple, easy to use, can be according to requirement when haircut to hair style, in real time to limiting comb when use It is adjusted, without replacing limiting comb.

Specific embodiment

Technical solution of the present invention described in detail below.The utility model embodiment is only for illustrating specific structure, the structure Scale should not be limited by the examples.

As shown in Figures 1 to 4, the utility model has the hair scissors of limiting comb regulating device, including limiting comb 1, adjusting Frame 2 adjusts ring 3 and knob 4；Limiting comb 1 is mounted at Hair scissor head, and limiting comb 1 is equipped with two branch angles 11, branch angle 11 One end be provided with round mouth 12；Adjusting bracket 2 is in H-type, and centre is semicircle bulge loop 23；An adjustable column 21 is fixed on bulge loop 23；It adjusts The both ends of frame are fixed with connection buckle 22, and the round mouth 12 on branch angle 11 sticks into connection buckle 22, so that it may by 2 phase of limiting comb 1 and adjusting bracket It is connected and fixed；It adjusts ring 3 to be mounted on adjusting bracket 2, adjusts ring 3 and be connected with knob 4；It adjusts ring 3 and is equipped with helical ring 31, A helix is formed on helical ring, adjustable column 21 is moved along helical ring 31.31 difference in height of helical ring is 3 centimetres.4 surface of knob Uniformly it is covered with convex block 41, it is one grade mobile that a displacement of each convex block can make limiting comb, therefore can precisely determine limiting comb Displacement.

Such as Fig. 4, adjustable column 21, his motion track is Z1......ZN, then we only need to control on helical ring The screw pitch h and helixangleβ of helix can realize that the motion track to adjustable column 21 controls, so that it may adjust the position of limiting comb It sets.
