Description

The handle of hand-held tool improves structure

Technical field

The utility model relates to a kind of handle and improves structure, and the handle that especially relates to a kind of hand-held tool improves structure.

Background technology

At present, the handle of the self-rotary hand-held tool of tradition reach nothing more than having with one-handed performance mode or bimanualness mode, and these modes of operation has been widely used on the various agitating devices of industrial production or daily life.

For example, No. 431874 [hand mixer] patent case at the TaiWan, China bulletin, it is the handle that utilizes the one-handed performance mode, it comprises that one has shell outside the handle, this shell comprises an electro-motor, this electro-motor makes the rotation of one of the axle that is contained in a fixed fitting first end, and second end that an instrument is fixed on axle constitutes; Or as, No. 424580 [the stirring rod structural improvement of agitator appends (one)] patent case at the TaiWan, China bulletin, also be the handle that utilizes the one-handed performance mode, it is by a stirring rod, and two agitators cooperate folder letter of commonly using and the agitator power source that is provided with handle to form.But above-mentioned two patent cases are to control lighter self-rotary hand-held tool (as agitator etc.) with one hand in the use, and for volume bigger or heavier agitator or vibrating drill utensil, the handle of this Dan Shou Shu control can't obtain to bring into play the function that it makes things convenient for steer direction.

Therefore, TaiWan, China is announced [agitator] patent case No. 236177, has provided a kind of structure technology of bimanualness mode, and it is to be equipped with on the electro-motor shell cross bar shape handle, grip for both hands, this kind cross bar shape handle can be controlled heavier or bigger self-rotary hand-held tool; But just as the person skilled in the art knows, this cross bar shape handle is when operation, and because of nothing is provided with supporting section or the analog that allows the user can rely on waist and belly in operating process, therefore, the user is more tired, particularly the part of arm; Especially at those vibrating drills or stir the occasion of sticky fluid for example.

For improving said circumstances, another kenel often know handle structure, be disclosed among the 1st figure, consist predominantly of a tubular body 20 and be bent into the handle of similar square, it is left and right, and to be arranged with lining 23 be two grippings place of the hand to being referred to as tubular cross bar 21,22, upper and lower tubulose cross bar 24,25 then inside packings are locked on the power source housing 26 with agitator, and this square handle is by forming 21,22,24,25 of the upper and lower, left and right on same plane tubulose cross bars, and upper and lower tubulose cross bar 24,25 and left and right tubulose cross bar 21,22 are symmetrical; Grip respectively on the left and right tubulose cross bar 21,22 with two hands during operation, sheer pole 25 then supports the waist and belly in the operator, handle by said structure, controlling heavier or bigger self-rotary hand-held tool, can conveniently control operation, and more can not allow operator's arm segment feel uncomfortable or tired very soon.But it structurally still has shortcoming to exist, for example go up, following tubulose cross bar 21,22 when inwardly packing is locked on the power source housing 26, must will go up, following tubulose cross bar 24,25 are pressed into flat horizontal surface, be locked on the power source housing 26 with retaining element 27 (as screw and so on) again, this situation can be destroyed, following tubulose cross bar 24,25 original structural strengths, and on, down, a left side, right tubulose cross bar 21,22,24,25 form the connection of right angle kenel, be easy to generate the stress concentration phenomenon, and make this structure after long-time the use, produce slight crack by stress raiser easily and destroy; Particularly in the implement system of those vibrations or boring.

In above-mentioned patent case, all demonstrate the improvement of relevant hand-held tool handle aspect structural design, they are to be utilized on the implements that are combined in power source, the Fang of acquisition Bian Shu control and laborsaving.

Yet the above-mentioned handle of quoting in the case relevant hand-held tool as proof also has the space of innovation improvement again, with in response to the demand property of difference and improve its use situation; For example, how making this handle structure reduce stress concentrates; Or consider known arc profile principle is incorporated on this handle structure, improve its planform: and make it can reach handled easily and laborsaving or improve conventional construction in when operation, user's arm is more easily ached or tired situation, in above-mentioned patent case, all do not disclosed or studied.

Summary of the invention

The purpose of this utility model is the above-mentioned deficiency at prior art, proposes the design of a kind of extended structure with slick and sly kenel space and the slick and sly section that rises and falls, and stress is concentrated and the handle improvement structure of the person's hand-held tool that meets the ergonomics to reduce.

Above-mentioned purpose of the present utility model is achieved through the following technical solutions: a kind of handle of hand-held tool improves structure, has the handle part that a rigid walls defines; Described handle partly includes a dish seat at zone line, in order to install a motor or main frame; One transition portion that extends along both sides between dish seat and one connects this transition portion, and comprises handle base portion that a control knob and fax line enter the mouth etc. and constitute; Have one between described transition portion and the handle base portion and set slick and sly radian, and the handle base portion has the end of big thickness on vertical section, can reduce the concentrated structure of stress in order to set up one jointly.

The configuration of the transition portion on its mid-game seat and both sides forms on the slick and sly indent, the lower surface, and this upper and lower end face is the radian design that cooperates the human lumbar belly, makes the wider field-of-view angle of upper surface formation, and the lower surface then can form comfortable supporting section; Wherein left and right handle base portion forms the slyness that the is inclined upwardly fluctuating section of symmetry; End face is provided with anti-skidding block person outside the wherein left and right handle; Wherein control knob is arranged at respectively on the left and right handle and holds, and this control knob is respectively the attached lock function of starting switch and torsion is recalled the attached speed setting knob of device; Wherein fax line inlet can be arranged at respectively under the left and right handle base portion and hold; The centre is provided with a trepanning among its mid-game seat, in order to install a motor or main frame.

Compare with prior art, the utlity model has following beneficial effect: reduce the stress concentration phenomenon, and it is comfortable that human body two hands are gripped.
