Description
Technical field
The present invention relates to screwdriver, specifically Laborsaving screwdriver.
Background technology
Screwdriver as a kind of common small tool, either in family life or in industrial production be all can not or
Scarce, it all brings great convenience for our life and production, but we can usually run into such situation, and one
A little screws are very painstaking when turning due to time too long surface oxidisation or other reasonses, especially at home only women and
During child, it is desirable to it is just more difficult to turn screw, meanwhile, its working end of used time is not very sharp for screwdriver, easily accidentally injures people, especially
Children, so as to having certain potential safety hazard, accordingly, it is capable to which no design is a kind of when the method reduction of some physics can be utilized to turn
Screwing force, meanwhile, turn into a difficulty being faced of technical staff in the screwdriver that the not used time protects screwdriver point of a knife
Topic.
The content of the invention
It is an object of the invention to provide Laborsaving screwdriver, to solve the problems mentioned in the above background technology.
To achieve the above object, the present invention provides following technical scheme：
Laborsaving screwdriver, including screwdriver body, the screwdriver body include screwdriver knife bar and screw driver handle, the spiral shell
Silk knife knife bar one end is provided with connection boss, and the connection boss includes the first ferromagnetic layer, articulamentum and the second ferromagnetic layer, and described the
Side of two ferromagnetic layers away from screwdriver knife bar is provided with articulamentum, and side of the articulamentum away from the second ferromagnetic layer is provided with first
Ferromagnetic layer, the side of the connection boss away from screwdriver knife bar are provided with screw driver handle, and the screw driver handle is close to connection
The side center of boss is provided with groove, and connects boss and be located in groove, and side of the groove away from connection boss is provided with blind
Hole, the circumference side of the screw driver handle are provided with anti-slip tank, and one end side of the screw driver handle away from screwdriver knife bar is provided with
Manhole, the manhole is interior to be provided with straight-bar.
Preferably, the straight-bar is hollow, and straight-bar diameter of bore is more than screwdriver knife bar diameter, and straight-bar length is equal to spiral shell
The length of silk knife knife bar.
Preferably, the diameter of the manhole is equal to the outer circumference diameter of straight-bar.
Preferably, the diameter of the blind hole is more than the outer circumference diameter of straight-bar.
Preferably, the connection boss is regular hexagon.
Preferably, the groove is regular hexagon, and iron hoop is provided with groove.
Preferably, the section of the anti-slip tank is rectangle.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention is ingenious in design, structure is novel, by setting up manhole on screw driver handle, and is furnished with straight-bar, so exists
The remote screwing force substantially reduced when turning of lever can be utilized when tightening screw；Set in the periphery of screw driver handle
Anti-slip tank can greatly increase frictional force when turning, and avoid skating；The connection boss of the regular hexagon of setting is by screwdriver hand
Handle is connected with screwdriver knife bar, and iron hoop is provided with screw driver handle groove, is connected boss and is provided with ferromagnetic layer, so, without
When screwdriver knife bar can be received in blind hole, avoid point of a knife may caused by it is dangerous.
Brief description of the drawings
Fig. 1 is the structural representation of Laborsaving screwdriver；
Fig. 2 is the structural side view of Laborsaving screwdriver；
Fig. 3 is structural representation when Laborsaving screwdriver is deposited.
In figure：1 screwdriver knife bar, 2 connection boss, 3 grooves, 4 anti-slip tanks, 5 blind holes, 6 straight-bars, 7 manholes, 8 screws
Knife handle, 9 screwdriver bodies, 10 first ferromagnetic layers, 11 articulamentums, 12 second ferromagnetic layers.
Embodiment
The technical scheme of this patent is described in more detail with reference to embodiment.
Fig. 1-3, Laborsaving screwdriver, including screwdriver body 9 are referred to, screwdriver body 9 includes screwdriver knife bar 1 and spiral shell
Silk knife handle 8, the one end of screwdriver knife bar 1 are provided with connection boss 2, and connection boss 2 includes the first ferromagnetic layer 10, articulamentum 11 and the
Two ferromagnetic layers 12, the second side of the ferromagnetic layer 12 away from screwdriver knife bar 1 are provided with articulamentum 11, and articulamentum 11 is ferromagnetic away from second
The side of layer 12 is provided with the first ferromagnetic layer 10, and side of the connection boss 2 away from screwdriver knife bar 1 is provided with screw driver handle 8, screw
Knife handle 8 is provided with groove 3 close to the side center of connection boss 2, and connects boss 2 and be located in groove 3, and groove 3 is away from connection
The side of boss 2 is provided with blind hole 5, and the circumference side of screw driver handle 8 is provided with anti-slip tank 4, and screw driver handle 8 is away from screwdriver knife
One end side of bar 1 is provided with manhole 7, straight-bar 6 is provided with manhole 7, straight-bar 6 is hollow, and the diameter of bore of straight-bar 6 is big
