Preferably, one end relative with cutter head on described knife bar is provided with handle of a knife, and the lateral surface of handle of a knife is provided with groove.
Preferably, the side of described handle of a knife axis is provided with and is convenient to hand-held section.
Preferably, the angle between the axis of described adjustable-angle screwdriver and the axis of screw is 0-45 °.
Preferably, the angle between the axis of described adjustable-angle screwdriver and the axis of screw is 30 °.
After adopting technique scheme, this utility model has following good effect:
(1) cutter head of the present utility model is provided with round and smooth projection and groove, described screwdriver with screw effect need tilt certain angle time groove to provide to screwdriver angle break-in and regulate space, boss is the direct effect position making screw tightening simultaneously, by protruding coordinating with groove, make screwdriver can tilt certain angle to screw applying effect;
(2) handle of a knife of adjustable-angle screwdriver of the present utility model is provided with groove and section, and convenient operation personnel are hand-held, increases property easy to use.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
As shown in figs. 1-7, be adjustable-angle screwdriver of the present utility model, comprise knife bar 1, cutter head 2 and handle of a knife 3, three is fixedly connected with, one-shot forming.Cutter head 2 is located at one end of knife bar 1, and handle of a knife 3 is located at the other end of knife bar 1.
The transverse section at any place of cutter head 2 is all in regular hexagon.Cutter head 2 is respectively equipped with head and the tail the first cutter block 201, the second cutter block 202, the 3rd cutter block 203, four blade block 204, the 5th cutter block 205 and the 6th cutter block 206 that are fixedly connected with apart from knife bar 1 direction that draws near, and the 6th cutter block 206 is fixedly connected with knife bar 1.By the direction that draws near apart from knife bar 1, the cross sectional area of the first cutter block 201 and the second cutter block 202 increases all gradually, and any place's cross sectional area of the second cutter block 202 is all greater than any place's cross sectional area of the first cutter block 201.The cross sectional area at the middle part of the 3rd cutter block 203 is greater than the cross sectional area at both ends, forms protruding 21 thus.By the direction that draws near apart from knife bar 1, the cross sectional area of four blade block 204 reduces gradually.The cross sectional area at the middle part of the 5th cutter block 205 is less than the cross sectional area at both ends, forms groove 22 thus.By the direction that draws near apart from knife bar 1, the cross sectional area of the 6th cutter block 206 increases gradually.First cutter block 201, second cutter block 202, the 3rd cutter block 203, four blade block 204, the 5th cutter block 205 are connected successively with the 6th cutter block 206, and form described cutter head 2, the lateral surface of cutter head 2 is round and smooth camber line, is convenient to described screwdriver angle break-in.
The lateral surface of handle of a knife 3 is provided with groove 31, and the side of handle of a knife 3 axis is provided with section 32, and section 32 is in I shape.Groove 31 and section 32 cooperatively interact, and convenient operation personnel are hand-held.
By arranging the size of cutter head 2 diverse location place cross sectional area, the radian of adjustment protruding 21 and groove 22, makes the angle between the axis of screwdriver and the axis of screw can control between 0-45 °.In the present embodiment, the angle between the axis of screwdriver and the axis of screw is 30 °, in use, because of operation convenience reason, when needing to tilt to use to screwdriver, the screwdriver of the present embodiment can be tilted 30 °, with to screw tightening.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain that this utility model requires.
