Abstract
The invention discloses a power-assistance screwdriver which comprises a handle and a bolt tool bit, wherein the handle comprises a power-assistance handle and a fixing handle for fixing the bolt tool bit; a slide block bulged outwards is arranged the end part of one out of the power-assistance handle and the fixing handle; the other one out of the power-assistance handle and the fixing handle is provided with a slide tongue extending outwards; a slide groove is formed in the slide tongue; the outer end of the slide block is fixed in the slide groove by a fixing pin and connected with the slide tongue in a sliding manner; and a cavity which is dented inwards and used for placing the slide tongue or the slide block of the other handle is arranged at the end part of each of the power-assistance handle and the fixing handle. The novel power-assistance screwdriver is specially used for solving the problem that a screw cannot be screwed due to a small screwing force of a common screwdriver, and rustiness and the like; the screwdriver has no difference from the common screwdriver on the surface; however, the screwdriver can be transformed by simple operation when the above situation is encountered; the screwing force can reach 5-10 times of that of the common screwdriver; and the screwdriver can allow a user to produce the great screwing force with a small effort.
Description
Technical field
The present invention relates to a kind of new power-assisted screwdriver.
Background technology
We are frequently encountered screw because the reason such as corrosion is it is impossible to turn, common way is to add in real work
Enter bolt looseness agent, but the method is also not omnipotent, sometimes still cannot turn bolt, and use during bolt looseness agent except needing
Outside waiting time that will be very long, may need for afterwards assisting by instruments such as adjustable wrenches so that simple work becomes
Extremely complex, if do not carry spanner possibly cannot continue.
Content of the invention
The technical problem to be solved be realize that one kind can turn at short notice cannot because of reasons such as corrosions
The instrument of the bolt turning.
To achieve these goals, the technical solution used in the present invention is: a kind of power-assisted screwdriver, including handle and screw driver
Head, described handle includes boost bar and the fixed handle of fixed screw cutter head, in described boost bar and fixed handle
An end be provided with outwardly slide block, another is provided with the sliding-tongue stretching out, and described sliding-tongue is provided with chute, described
Slide block outer end be fixed in chute by steady pin and be slidably connected with sliding-tongue, described boost bar and fixed handle end set
There is the cavity caving inward for placing the sliding-tongue on another handle or slide block.
Described boost bar and fixed handle coupling part are provided with external screw thread, and by having female fixed cover even
Connect fixation.
Described slide block is two laminated structures, and clamps sliding-tongue.
The screw that new power-assisted screwdriver cannot turn the reasons such as corrosion exclusively for the common screwdriver of solution because stubborn power is little, this kind
See on screwdriver surface and have no difference with common screwdriver, but when running into above-mentioned situation, can be deformed by shirtsleeve operation, stubborn power
Up to 5～10 times of common screwdriver, the strength of user very little can be allowed to produce power of greatly twisting.
Brief description
Below content of width accompanying drawing expression every in description of the invention and the labelling of in figure are briefly described:
Fig. 1 is structural representation under power-assisted screwdriver normal service condition；
Fig. 2 is power-assisted screwdriver extended state structural representation；
Fig. 3 is structural representation under power-assisted screwdriver power-assisted use state；
Fig. 4 is slipper structural representation in Fig. 2；
Fig. 5 is slipper structural representation in Fig. 3；
The labelling of above-mentioned in figure is: 1, driver bit；2nd, handle；3rd, boost bar；4th, fixed handle；5th, fixed cover；
6th, slide block；7th, sliding-tongue；8th, steady pin；9th, chute.
Specific embodiment
Understand referring to Fig. 1-5, power-assisted screwdriver includes handle 2 and bolt cutter head 1, wherein handle 2 by boost bar 3 and is fixed
The fixed handle 4 of driver bit 1 is constituted, and one of boost bar 3 and fixed handle 4 end is provided with outwardly slide block 6, separately
One is provided with the sliding-tongue 7 stretching out, and is provided with slide block 6 with boost bar 3 below, and fixed handle 4 enters as a example being provided with sliding-tongue 7
Row explanation, above-mentioned sliding-tongue 7 is provided with chute 9, and slide block 6 outer end is fixed in chute 9 by steady pin 8 and is slidably connected with sliding-tongue 7,
So boost bar 3 and fixed handle 4 are in the relation that is slidably connected, and boost bar 3 can be turned in chute 9 by steady pin 8
Dynamic, carry for the ease of screwdriver and conventional use, the one end being provided with slide block 6 on boost bar 3 is provided with for placing sliding-tongue 7
Cavity, the one end being provided with sliding-tongue 7 accordingly on fixed handle 4 is provided with cavity for placing slide block 6, such boost bar 3
When drawing in fixed handle 4, slide block 6 and sliding-tongue 7 all slip in cavity, afterwards in boost bar 3 and fixed handle 4 coupling part
Setting external screw thread, and be connected by having female fixed cover 5, then screwdriver can recover profile and the work(of common screwdriver
With.
Screwdriver, when using assist function, only need to turn on fixed cover 5, boost bar 3 and fixed handle 4 stretch opposite to each other, it
Rotate boost bar 3 afterwards, make boost bar 3 and fixed handle 4 be in 90 degree of angles, then can be expanded using lever principle and twist bolt
Strength.In order to improve dependability, slide block 6 suggestion is designed to two laminated structures, and clamps sliding-tongue 7, so can be
Using screwdriver assist function when, reduce the torsion between steady pin 8 and chute 9, torsion shared equally slide block 6 and sliding-tongue 7
Dependability and the service life of power-assisted screwdriver on contact surface, can be effectively improved.
Above in conjunction with accompanying drawing, the present invention is exemplarily described it is clear that the present invention implements is not subject to aforesaid way
Restriction, as long as employing the improvement of various unsubstantialities that method of the present invention design and technical scheme are carried out, or without changing
Enter and the design of the present invention and technical scheme are directly applied to other occasions, all within protection scope of the present invention.
