Specific implementation mode

The embodiments of the present invention are further illustrated below in conjunction with attached drawing.

It refers to shown in attached drawing 1 to attached drawing 4, a kind of effort-saving Portable screwdriver, including knife bar 1, handle of a knife 2, flexible card Button 3, extension bar 4 and angle chain 5；2 bottom of handle of a knife offers step cutting pattern hole 201, and the step cutting pattern hole 201 apertures are provided with the telescopic buckle 3；The knife bar 1 is metal round rod, and close to 1 top surface of knife bar Peripheral wall on be provided with card slot 101；The knife bar 1 is arranged in the step cutting pattern hole 201, and can be along described 2 axial-movement of handle of a knife；2 top of handle of a knife is provided with the angle chain 5 described in a pair；The angle chain 5 includes 501 He of interconnecting piece Rotation section 502, the interconnecting piece 501 are hinged with rotation section 502；The interconnecting piece 501 is fixed on 2 peripheral wall of handle of a knife On, the rotation section 502 is connect with the extension bar 4.

2 top surface of handle of a knife offers the first arc groove 202, and 202 axis of the first arc groove with it is described 2 axis of handle of a knife it is vertical.

1 top surface of knife bar is provided with cylindrical boss 102, and 102 diameter of boss is more than the knife 1 diameter of bar；The step cutting pattern hole 201 includes aperture 203 and macropore 204；The aperture 203 is arranged in the handle of a knife 2 bottoms, and internal diameter is less than 204 internal diameter of macropore.

1 diameter of knife bar is identical as 203 internal diameter of aperture, in the boss 102 and the macropore 204 Diameter is identical so that while knife bar has retractility, can also limit the movement of knife bar, improve the reliable operation of screwdriver Property.

The maximum angle of the rotation section 502 and interconnecting piece 501 is 90 °, ensures that extension bar can be in the receipts of screwdriver Receive state and working condition switching.

The extension bar 4 is metal round rod, and 4 axis of extension bar and 202 axis of the first arc groove Line is in same plane；4 radius of extension bar is identical as 202 radius of the first arc groove, ensures extension bar in screw It is fallen when the working condition of knife in the first arc groove, increases the contact area of extension bar and handle of a knife so that the work of screwdriver is more Reliably.

The handle of a knife 2, which is evenly distributed, offers several second arc grooves 205, is only needing to carry out screwdriver using handle of a knife When rotation, the frictional force between handle of a knife and palm can be increased so that screwdriver user is more laborsaving.

In use, the knife bar 1 is moved along the protruding and described telescopic buckle 3 in the step cutting pattern hole 201 It moves to the card slot 101, the relative position being kept fixed with handle of a knife 1 to the knife bar 1 described in ensureing；Then, described Rotation section 502 rotates, to which the extension bar 4 for realizing described is contacted with first arc groove 202, the last screwdriver Reach working condition.

When storage, the rotation section 502 drives the extension bar 4 to be routed up from first arc groove 202, and rolls over It is folded to be arranged on the outside of 2 peripheral wall of handle of a knife；Then the telescopic buckle 3 is detached with the card slot 101, the knife bar 1 is retracted to 201 end of step cutting pattern hole, finally moves to the knife bar 1 in the step cutting pattern hole 201 Portion, to which the screwdriver reaches receiving state.

The above is only the preferred embodiment of the present invention, and it does not limit the scope of the patent of the present invention, It is every to utilize equivalent structure transformation made by the utility model description, it is directly or indirectly related with other are attached to The technical field of product, is equally included in the patent within the scope of the utility model.
