Description
Technical field
The utility model relates to the improvement to utility screwdriver, specifically a kind of power-assisted screwdriver that assister bar is installed on screw driver handle.
Background technology
Screwdriver of the prior art, consists of interconnective handle and cutter hub conventionally, is for twisting screw to force its instrument in place.The front end of cutter hub has one conventionally can insert the line of rabbet joint of screw cap or the thin sphenocephaly in recess, and this thin sphenocephaly mainly contains two kinds of a word (negative sign), crosses (positive sign); Or cutter hub front end is hexagon, comprise two kinds of versions of interior hexagonal and outer-hexagonal, generally one-tenth is hex(agonal)screw cutter.But above-mentioned screwdriver has following problem: when screwdriver uses, operator generally all the handle of this screwdriver dominated by hand, it is applied to twisting resistance, thereby tighten the screw that cutter hub front end is corresponding; But, if screw gets rusty or operator's strength is limited ... in situation, use very effort of screwdriver tighten the screws nail, be at this moment just badly in need of a kind of screwdriver with boosting mechanism.
Summary of the invention
The purpose of this utility model is: for addressing the aforementioned drawbacks, provide a kind of screwdriver with boosting mechanism.
The technical solution adopted in the utility model is:
A kind of power-assisted screwdriver, comprise interconnective handle and cutter hub, described handle rear end is inwardly provided with a cavity, along being disposed with assister bar and the guide post being hinged in handle axis, cavity, along handle axis, cavity side, be provided with chute, the end of chute is provided with plug, is provided with slide block, slide block connects guide post front end by bearing pin in chute.
The end of described assister bar is to being outside equipped with limited block.
Described cavity end is provided with internal thread, and plug is the anticreep plug of a ladder barrel shape.
Described assister bar, guide post, slide block and chute are some covers, and symmetry is distributed on cavity inside, between slide block, by spring, connect.
The beneficial effect that the utility model produces is:
Power-assisted screwdriver of the present utility model is simple in structure, at screw driver handle end, telescopic assister bar is set, while using power-assisted screwdriver, can, by assister bar draw-out handle end, increase screw driver handle diameter, increase moment, facilitate the dismounting of screw or bolt and fastening, time saving and energy saving in the process of the turn of the screw, tighten the screws further, efficiently convenient, simple to operate, easy to use, be particularly suitable for the people that strength is less and use.While not using the assister bar of power-assisted screwdriver, assister bar can be taken in handle end cavity, safety is attractive in appearance, the structure that do not affect screwdriver.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of specific embodiment of the present utility model;
Fig. 2 is the use status architecture schematic diagram of the specific embodiment shown in Fig. 1;
Number in the figure represents: 1-spring, 2-guide post, 3-bearing pin, 4-assister bar, 5-plug, 6-chute, 7-bearing pin, 8-slide block.
The specific embodiment
Shown in Fig. 1, Fig. 2, the utility model is a kind of power-assisted screwdriver, comprises interconnective handle and cutter hub.Handle rear end is inwardly provided with a cavity, along being disposed with assister bar 4 and the guide post 2 being hinged in handle axis, cavity, in this specific embodiment, assister bar 4 front ends and guide post 2 end correspondences are provided with the installing hole of bearing pin 3, are provided with the bearing pin 3 that assister bar 4 is connected with guide post 2 in installing hole.Along handle axis, cavity side, be provided with chute 6, the end of chute 6 (being corresponding cavity terminal position) is provided with plug 5.In chute 6, be provided with slide block 8, slide block 8 by bearing pin 7 connection guide post 2 front ends.In the time need to using the assist function of the utility model power-assisted screwdriver, assister bar 4 to be pulled out in cavity, slide block 8 moves, makes guide post 2 to lead in cavity along handle axis along chute 6, then assister bar 4 is outwards overturn, and makes it be stuck in handle cavity end.Now, the boosting mechanism stable connection of power-assisted screwdriver, reverses handle to assister bar 4 application of forces, thereby strengthens screwing force, can easily tighten or unscrew the screw of cutter hub front end.
In addition, the end of assister bar 4 is to being outside equipped with limited block.The design of this limited block, makes assister bar 4 be difficult for deviating from when not pulling out cavity, meanwhile, when limited block can be used as operating personnel and draws assister bar 4, hand-held stressed member, is conducive to fast and effeciently pull it.
In this specific embodiment, cavity end is provided with internal thread, and plug 5 is anticreep plugs of a ladder barrel shape.The microcephaly of this anticreep plug holds corresponding chute 6 end settings, and step surface periphery coordinates cavity end and sidewall to install, and respective outer side edges is tight, and assister bar 4, guide post 2 and slide block 8 are limited in handle cavity.
It should be noted that: assister bar 4, guide post 2, slide block 8 and chute 6 can be some covers, and symmetry is distributed on cavity inside, between slide block 8, by spring 1, connect.As shown in Figure 1, 2, in this specific embodiment, assister bar 4, guide post 2, slide block 8 and chute 6 are 2 covers, 2 chutes 6 are symmetricly set on correspondence on cavity both sides, chute 6 and are provided with slide block 8 separately, between 2 slide blocks 8, be connected with the front end that connects respectively 2 guide posts 2 on 1,2 slide block 8 of spring by bearing pin 7.2 guide posts 2 use respectively hinged assister bar 4, the 2 interconnective guide posts 2 of cover of bearing pin 3 and assister bar 4 to be successively set on cavity center position.In like manner, assister bar 4, guide post 2, slide block 8 and chute 6 can be also 4 covers, and symmetry is distributed on cavity inside, and the tricks of assister bar 4, guide post 2, slide block 8 and chute 6 can be taken the circumstances into consideration design according to actual conditions, is not limited to above-mentioned concrete structure.
