Description

Rotating force increasable lever

Technical field

The utility model relates to a kind of handle of manual throw, particularly relates to a kind of rotating force increasable lever.

Background technology

At present, general manual throw as screwdriver, constitutes by a bar portion with a driving head and a handle.Wherein handle is smooth arcwall face, or forms 6 grooves on smooth arcwall face.The former moulding is more attractive in appearance, but makes effort; The latter can increase frictional force, but use still not ideal enough, the torque value in the time of can not improving it to greatest extent and use.

The utility model content

The technical problems to be solved in the utility model is, overcomes deficiency of the prior art and a kind of rotating force increasable lever is provided, and the application of force is convenient and more laborsaving in use to make the user.

The technical scheme that provides for solving the problems of the technologies described above is as follows.

According to rotating force increasable lever of the present utility model, comprise the handle body, form at least one recess in the front portion of this handle body, be formed with at least two fins at the rear portion of this handle body.

The technical scheme of the handle of above-mentioned increase revolving force of the present utility model is also realized further by technical characterictic as described below.

Wherein be formed with one and extend recess on the right side of described recess.

Say that more specifically described recess and fin are four.

In addition, described recess and fin are the dislocation configuration.

Have, described fin is the part of handle body itself or is a part that is attached on the handle body again.

The utility model compared with prior art has following tangible advantage and beneficial effect.

1. handle of the present utility model is because the anterior recess that forms, can provide user's thumb when the application of force, to push up the sincere point of application, apply revolving force to be more convenient for, and the fin that the rear portion forms is convenient to user's palm application of force, the synergy of the two makes the user in use, can keep maximum frictional force between hand and handle, thereby under the situation of light labour-saving, just can obtain bigger torque value.

2. handle of the present utility model, its structure meets ergonomics, thereby can reach best use habit.

3. handle of the present utility model, its structural design only are to have carried out some minor alterations on the handle body, and be therefore simple in structure, manufacturing cost is cheaper, so with regard to effect and practicality that it can reach, be value-for-money really, quite has the value on the industry.

4. in addition, handle of the present utility model, the extension that its recess right side forms can make user's thumb more fully be fitted on this extension, and obtains maximum application of force effect by this, makes that operation is lighter, laborsaving.

In sum, the utility model, it is in limited field, technical development space, no matter structurally or bigger improvement all arranged on the function, and have large improvement technically, and produced handy and practical effect, and have the effect of enhancement really, thereby being suitable for practicality more, really is a new and innovative, progressive, practical new design.

Below in conjunction with accompanying drawing and most preferred embodiment, the utility model is further described.

Fig. 3 is a use cutaway view embodiment illustrated in fig. 2.

Fig. 4 is the stereogram with most preferred embodiment of the utility model handle.

Fig. 5 is a use schematic diagram embodiment illustrated in fig. 2.

Among the figure: 10 ... handle 11 ... the bar portion of band driving head

20 ... handle body 21 ... recess

22 ... fin 23 ... extend protuberance

The specific embodiment

Screwdriver as shown in Figure 1, its bar portion 11 by handle 10 and band driving head constitutes.Wherein handle is 10 curved, and such moulding meets ergonomics, can make the user can feel more comfortable when gripping.But because the frictional force between itself and the palm is less, the torque value during turning of work piece is also little, does not therefore reach desirable use effect.

Shown in Fig. 2, Fig. 3 and Fig. 5 is an embodiment of rotating force increasable lever of the present utility model, and it is made of the bar portion of handle body 20 and band driving head.Be formed with 4 equally distributed recesses 21 of circumferencial direction in the front portion of handle body 20, also be formed with 44 fins 22 that shift to install with described recess 21 at the rear portion of handle body 20, and these 4 fins be to be secured in addition on the handle body 20.The force application part that provides the top to pull in the point of application that thumb during the described recess user application of force provides the top to pull, the described fin palm during then for user's application of force makes the bigger frictional force of palm and handle maintenance.

Shown in Fig. 4 and Fig. 5 is the most preferred embodiment of rotating force increasable lever of the present utility model, and it also forms on the right side of described each recess 21 and extend recess 23 except having Fig. 2 and structure shown in Figure 3.Like this, can be so that user's thumb be fitted on this extension 23 fully, thus reach the maximum application of force effect of thumb.Cooperate the applying of palm and fin 22 again and increase frictional force when using, finally make the user lighter, laborsaving, practical when operation.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
