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 novel power-assisted screwdriver.
Background technology
We are in real work; often can run into screw because reasons such as corrosions; cannot turn; common way is to add bolt looseness agent, but the method is also not omnipotent, sometimes still cannot turn bolt; and while using bolt looseness agent except needs are very long stand-by period; may or need to assist by the instrument such as monkey wrench afterwards, making simple work become extremely complicated, if carry spanner, possibly cannot not continue etc.
Summary of the invention
Technical problem to be solved by this invention is to realize a kind ofly can turning at short notice the instrument of the bolt that cannot turn because of reasons such as corrosions.
To achieve these goals, the technical solution used in the present invention is: a kind of power-assisted screwdriver, comprise handle and bolt cutter head, described handle comprises the fixed handle of boost bar and fixed screw cutter head, an end in described boost bar and fixed handle is provided with outwardly slide block, another is provided with outward extending sliding-tongue, described sliding-tongue is provided with chute, described slide block outer end is fixed in chute and is slidably connected with sliding-tongue by steady pin, described boost bar and fixed handle end are provided with and cave inward for placing sliding-tongue on another handle or the cavity of slide block.
Described boost bar and fixed handle coupling part are provided with external screw thread, and are connected and fixed by the female fixed cover of tool.
Described slide block is two laminated structures, and clamps sliding-tongue.
Novel power-assisted screwdriver is specially for solving common screwdriver because twisting the little screw that cannot turn the reasons such as corrosion of power, this kind of screwdriver has no difference with common screwdriver outwardly, but while running into above-mentioned situation, by shirtsleeve operation, can be out of shape, twist the common screwdriver of Li Keda 5～10 times, can allow user by very little strength and produce the power of twisting greatly.

Fig. 5 is slipper structural representation in Fig. 3;
Mark in above-mentioned figure is: 1, driver bit; 2, handle; 3, boost bar; 4, fixed handle; 5, fixed cover; 6, slide block; 7, sliding-tongue; 8, steady pin; 9, chute.
The specific embodiment
Known referring to Fig. 1-5, power-assisted screwdriver comprises handle 2 and bolt cutter head 1, wherein handle 2 consists of the fixed handle 4 of boost bar 3 and fixed screw cutter head 1, an end in boost bar 3 and fixed handle 4 is provided with outwardly slide block 6, another is provided with outward extending sliding-tongue 7, with boost bar 3, be provided with slide block 6 below, fixed handle 4 is provided with sliding-tongue 7 and describes for example, above-mentioned sliding-tongue 7 is provided with chute 9, slide block 6 outer ends are fixed in chute 9 and are slidably connected with sliding-tongue 7 by steady pin 8, boost bar 3 and fixed handle 4 are the relation of being slidably connected like this, and boost bar 3 can be by steady pin 8 in the interior rotation of chute 9, for the ease of screwdriver, carry and conventional use, the one end that is provided with slide block 6 on boost bar 3 is provided with for placing the cavity of sliding-tongue 7, corresponding one end that is provided with sliding-tongue 7 on fixed handle 4 is provided with for placing the cavity of slide block 6, when boost bar 3 and fixed handle 4 draw in like this, slide block 6 and sliding-tongue 7 all slip in cavity, at boost bar 3 and fixed handle 4 coupling parts, external screw thread is set afterwards, and be connected and fixed by the female fixed cover 5 of tool, screwdriver can recover profile and the function of common screwdriver.
Screwdriver, when using assist function, only need be turned on fixed cover 5, and boost bar 3 and the opposing stretching of fixed handle 4, rotate boost bar 3 afterwards, makes boost bar 3 and fixed handle 4 be 90 degree angles, can utilize lever principle to expand the strength of twisting bolt.In order to improve dependability, slide block 6 suggestions are designed to two laminated structures, and clamp sliding-tongue 7, like this can be when using the assist function of screwdriver, reduce the torsion between steady pin 8 and chute 9, torsion is shared on the contact-making surface of slide block 6 and sliding-tongue 7 equally to dependability and the service life that can effectively improve power-assisted screwdriver.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
