Abstract

The utility model relates to a holding handle with improved structure. The holding handle is positioned on one end of a manual tool, and the other end of the holding handle is provided with a use end. A first, a second and a third concave parts which are suitable for the curvature of fingers and are concave inwards are respectively formed on the front, the middle and the rear parts of one lateral surface of the holding handle. Two convex parts which are outwards convex oppositely in a flat way are formed among the three concave parts. The other lateral surface of the holding handle is provided with a third concave part in a concave mode in a position slightly opposite to the first concave part of one lateral surface, and a flat third convex part is outwards arranged behind the third concave part convexly. Simultaneously, the foremost end of the upper side of the holding handle is inwards provided with a fourth concave part in a concave moce. Different holding and force applying modes can be selected according to different states and use to achieve the comfort and efficacy of use.

Description

The handle structure improvement

The utility model provides a kind of handle structure, is meant a kind of handle structure improvement especially.

The normal hand-held tool that uses in the daily life, saw, knife, fruit knife, graver etc. are arranged, in general its handle of relatively large hand-held tool is all bigger, and the gripping and the application of force that are suitable for hand, but ignore the comfortableness when gripping, cause when using not good because of gripping sense, and the direction that lacks the application of force is auxiliary, the flexibility ratio of its operation relies on the action of wrist fully, and often slide, point the bump article, drop and wrist portion situation such as ache, these all are general hand-held tool grips handle with whole palm shortcomings; As saw, western-style food cutter etc.

For another example, scroll saw in the saw, because the saw plate of scroll saw is thin as wire, when being used in the saw article,, then be very difficult to grasp the direction of its application of force and the direct of travel of saw thereof as the related work practitioner of non-frequent use, only common people have no way of selecting, have only purchase, use general existing commercially available scroll saw, difficulty when it grips, easily slide and be unfavorable for using, therefore necessaryly further improve.

Edge this, the utility model creator through observe for a long time, research, design this simple and easy hand-held tool handle that closes again in ergonomics, numerous users' better choice is provided.

Main purpose of the present utility model promptly provides a kind of handle structure improvement, refers to a kind of hand-held tool handle structure design that meets ergonomics especially, particularly about handle purpose tight based on gripping, that be convenient to the application of force.

The improvement of the utility model handle structure, wherein this handle is an end that is positioned at hand-held tool, the other end then is provided with a use side, three ones are formed with first, second and third recess that caves inward that is fit to the finger curvature respectively before, during and after one side of this handle, form the protuberance of two outside relatively smooth-going projectioies between three recesses, first recess location of rough aforementioned relatively side, the another side of handle is concaved with the 3rd recess, and its rear also outwards is convexly equipped with the 3rd a smooth-going protuberance, and the upside of handle is concaved with the 4th recess foremost simultaneously; Thumb is fit to the 3rd recess during gripping, and middle finger, the third finger and little finger of toe be first, second and third recess of the relative side of clamping handle respectively then, so can provide hand comfortable and grip closely, reaches comfortable in the use.

Another purpose of the present utility model, the upside that promptly is aforementioned handle is concaved with the 5th recess foremost, when must use bigger strength in use side so as to saw more efficiently, when cutting article, then push against the 5th recess, provide downwards a strength in by the object of the application of force with forefinger finger tip portion; Can provide the user to comply with different situations, purposes, selection grips and force mechanism with difference, and reaches the effect in the use.

Another purpose of the present utility model is to be provided with anti-skidding portion in first, second, third and fourth recess of aforementioned handle, is beneficial to the clamping of finger, avoids the shortcoming of slippage.

Wherein among first, second, third and fourth recess of this handle, be provided with anti-skidding portion.

Wherein this use side can be scroll saw.

Wherein this use side can be the western-style food cutter.

Wherein this use side can be provided with different use sides with the difference of purposes.

For making your juror understand the purpose of this utility model, feature and effect, now by following specific embodiment, and cooperate appended graphicly, the utility model is described in detail, wherein:

Fig. 1 is for commonly using the stereogram of structure;

Fig. 2 is stereogram of the present utility model;

Fig. 3 is user mode figure of the present utility model;

Fig. 4 implements illustration for of the present utility model another.

As shown in Figure 1, be for commonly using the stereogram of scroll saw 100, its handle 3 is to be general level and smooth rod shape, easy slippage when general user grips, so very difficult controlling party to, very inconvenient in the use, grip also uncomfortable.

Shown in Figure 2, it is stereogram for the utility model scroll saw (hand-held tool) 100, mainly include handle 1 and scroll saw end (use side) 2 two parts, wherein, this handle 1 is an end that is positioned at scroll saw (hand-held tool) 100, before one side of this handle 1, in, three ones of backs be formed with respectively be fit to the finger curvature cave inward first, two, three

recesses

11,12,13, form first of two outside relatively smooth-going projectioies between three recesses,

second protuberance

16,17, first recess, 11 positions of rough aforementioned relatively side, the another side of handle 1 are concaved with the 4th recess 14, and its rear also outwards is convexly equipped with the 3rd a smooth-going protuberance 18, the upside of handle 1 faces wiring saw end (use side) 2 places foremost simultaneously, is concaved with the 5th recess 15;

This scroll saw end (use side) 2, in conjunction with the front end of being located at handle 1, it is made up of a bow portion 21 and wire saw board 22;

As shown in Figure 3, be fit to the 4th recess 14 with thumb during use, middle finger, the third finger and little finger of toe are then distinguished first, second and

third recess

11,12,13 of clamping handle 1 a relative side, provide hand comfortable and gripping closely; And when the user must use bigger strength in scroll saw end (use side) 2 so that saw more efficiently, when cutting article, then push against the 5th recess 15 with forefinger finger tip portion, impose downwards a strength in by the object of the application of force; The direction that can provide user's hand to grip closely and effectively control the application of force and advance; The utility model can be complied with different situations, purposes, and selection grips and force mechanism with difference, and reaches the comfortable and better effect in the use.

In addition, as shown in Figure 4, for the utility model is used in the enforcement illustration of western-style food cutter 200, the mode of its use is same as the situation of scroll saw 100.

In addition, the utility model is to avoid the deficiency of user because of curable grip, can be among aforesaid first, second, third and

fourth recess

11,12,13,14, add anti-skidding 19 and strengthen curable grip, avoid slippage and shadow to the effect that grips.

In sum, handle structure provided by the utility model improvement not only has utility function, and is not seen in public use, thus met the important document of the novel patent of Patent Law, hence in accordance with the law the mere formality application it.

The diagram of above said content and illustrated embodiment only is a preferable enforcement example of the present utility model, and all various variations and modifications that makes according to spirit of the present utility model must be included in the claim of the present utility model.

For this reason, ask your juror to know clearly and give examination, and pray and grant quasi patent early, to feeling moral just.
