Description
Technical field
The utility model relates to hardware ﹠ tools, more specifically to a kind of screwdriver.
Background technology
Screwdriver is one of instrument commonly used in people's live and work, and it comprises knife bar and handle, and the front end of knife bar is provided with cutter head, and cutter head is in-line or cross, and the rear end of knife bar is arranged in handle, is fixedly connected with handle.Existing screwdriver need to be held handle with palm in use, by rotary handle, makes cutter head drive screw threads and transfers and realize the fastening of screw or unscrew after holding with a firm grip.Owing to the torsion that screws screw is that armrest is slapped and the static friction of handle is conducted, when running into the screw that becomes rusty solid, and many times can screw can not be backed out because of grip is not enough, even screw screws down the most at last, also can require great effort very much.
Summary of the invention
The purpose of this utility model provides a kind of Laborsaving screwdriver, can like a cork screw be unscrewed to back out.
Laborsaving screwdriver described in the utility model comprises knife bar and handle, and the front end of knife bar is provided with cutter head, is fixed with connector at the handle front end, and connector front end end face offers groove, and it is hinged by bearing pin and connector front end that the rear end of knife bar is arranged in this groove.
Bottom at described groove is provided with collision bead, and end face offers the location pit in the knife bar rear end, and the pearl of collision bead is arranged in this location pit.
The structure that the location pit matches with collision bead can reliably be located knife bar, prevents that knife bar from affecting the normal use of screwdriver in use easily around the hinging pin shaft rotation.
During use, identical with normal screws cutter using method in usual situation.When running into the screw that not too easily turns, knife bar can be rotated around hinging pin shaft, make the screwdriver bending L-shaped, keep driver bit to be connected with screw application of force groove, take knife bar as the axis swinging handle, can realize the dismounting of screw.
Laborsaving screwdriver described in the utility model, but because the screwdriver bending is L-shaped, in the situation that L-shaped, according to lever principle, rotate handle of a knife and just can provide a larger moment of torsion to knife bar, screw off thereby can easily screw be unscrewed, time saving and energy saving.
