Abstract
The utility model relates to a tool handle. A grab handle part of a tool body is formed into the shape of a ball rod, a tiger-mouth part of the grab handle part can be formed with a ring having the largest radius when the grab handle part is held relative to a hand part, the ring having the largest radius can be tightly buckled and held by a thumb, the tiger-mouth part and a fore-finger of a user, and force can be applied to the ring having the largest radius when a screw element is wrenched. The ring having the largest radius is the largest part of a force arm, the user can exert force on the largest part of the force arm in the most powerful mode during holding via the position of the ring having the largest radius in order to generate the maximum moment, and thus the screw element which is tightly fixed can be easily wrenched; the user's work efficiency can be effectively increased.
Description
Technical field
The utility model relates to a kind of tool of manually starting building, and relates in particular to the comparatively fastening screw tightening of a kind of switching easily, so the tool handle that promotes user's operating efficiency can be arranged.
Background technology
Current people take action on one's own to arrange and contain the DIY general mood day in the family, it is quite mature and stable to add domestic hand-held tool development, no matter wherein be product category or architecture quality, more win domestic and international consistent affirming, hand-held tool production industry is over the years in order to make the easier in use left-hand seat of general consumption masses, so the hand-held tool of various easy operating or subsidiary hommization function is also asked the city successively.
See also shown in Figure 4, existing bottle opener tool handle comprises a shank part and a driving head, but this driving head spiral shell changes screw tightening, and this shank part is to grip the application of force for the user to use, because of the radius of its shank part greater than the radius of driving head, spinning force so can use lever principle with the user amplifies, and the strength after amplifying is rotated screw tightening, so that with screw tightening locking or spiral shell pine.This kind design is because of simple in structure, easy to operate, and has the effect of repetitiousness disassembly and assembly, therefore generally is used in junction of all sizes, and makes the bottle opener instrument become very common hand-held tool.
Yet,, need bigger strength can lock or during the screw tightening of spiral shell pine, existing handle structure just can't be given full play to effectiveness when running into though the existing bottle opener instrument of this kind has the utilization lever principle effect of establishing screw tightening with spiral shell.Because of existing bottle opener tool handle in the top, the tiger place that is the corresponding user's of being used for hand is the arc design of adopting depressed, its radius is smaller than the remainder of shank part, and thumb is a strongest finger in five fingers of hand, so existing shank part structural design also fails effectively to allow user's thumb, tiger, forefinger link closely, and can't be to be easy to most the gripping mode switching screw tightening of the application of force, event is the comparatively fastening screw tightening of switching effectively, therefore as a complete unit, its practicality is relatively poor, and in addition improved necessity is arranged in fact.
The utility model content
In order to overcome the above-mentioned shortcoming that existing tool handle exists, the utility model provides a kind of improved tool handle, the utility model is the comparatively fastening screw tightening of switching easily, so the operating efficiency that promotes the user can be arranged, has suitable practicality and progressive really.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of tool handle, tool body have a shank part, and the shank part leading portion has pulling part, it is characterized in that: the tiger place had a maximum radius ring when shank part leading portion gripped corresponding to hand.
Aforesaid tool handle, wherein the maximum radius ring is 1/4 to 1/10 of a shank part length overall apart from the shank part front end length.
Aforesaid tool handle, wherein the shank part bottom is provided with an anti-delinking part.
The utility model is the comparatively fastening screw tightening of switching easily, so the operating efficiency that promotes the user can be arranged, has suitable practicality and progressive really.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the stereoscopic schematic diagram of the utility model tool handle.
Fig. 2 is the outward appearance floor map of the utility model tool handle.
Fig. 3 is the user mode figure of the utility model tool handle.
Fig. 4 is existing bottle opener instrument user mode figure.
The number in the figure explanation:
1---tool body 10---shank part
11---anti-delinking part 12---maximum radius ring
20---pulling part 21---pulling head
The specific embodiment
See also Figure 1 and Figure 2, the utility model tool handle comprises a tool body 1, this tool body 1 can be embodied as a bottle opener instrument, this tool body 1 has a shank part 10 for user's gripping, extend pulling part 20 forward by shank part 10, this pulling part 20 be provided with a pulling head 21 foremost, this pulling head 21 is used for switching screw tightenings.
Above-mentioned shank part 10 integral body are generally to be a bat shape, shank part 10 bottoms have the anti-delinking part 11 in big footpath, when this anti-delinking part 11 can prevent that user's hand from gripping shank part 10 because of coming off accidentally, and this shank part 10 is gradually wide from lower to upper, and, correspond to the tiger place of human hands when gripping and form maximum radius ring 12 at the leading portion of shank part 10.This maximum radius ring 12 is about 1/4 to 1/10 of shank part 10 length overalls apart from the length of shank part 10 front ends, and this maximum radius ring 12 is than the other parts greater than shank part 10.By the shape of these maximum radius ring 12 cooperation hands, make the enough thumbs of user's energy, tiger, forefinger that the shank part 10 of tool body 1 is hung on to, be beneficial to the application of force.
The utility model in use, see also shown in Figure 3, when the user grips the shank part 10 of this tool body 1 with hand, because of cooperating hand tiger part to be formed with a maximum radius ring 12 on the shank part 10, can be beneficial to the user by this maximum radius ring 12 grips it with thumb, tiger, forefinger, and when application of force switching screw tightening, because of the arm of force of maximum radius ring 12 the arm of force, so can produce bigger moment with the switching screw tightening much larger than pulling part 20 pulling heads 21.The utility model is arranged at the maximum radius ring 12 of shank part 10 front end of shank part 10, make it can cooperate the tiger of hand, make the user when gripping, can force in arm of force maximum in the strongest mode, to produce the strongest moment, so just the comparatively fastening screw tightening of switching easily reaches the purpose that improves user's operating efficiency.
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.
