The specific embodiment:

At first see also shown in Figure 1, the utility model provides a kind of screwdriver structure to improve, mainly comprise: screwdriver 10 constitutes with revolving part 20, wherein: a screwdriver 10 is established a screwdriver head (11) in the tip side position, screwdriver head (11) but the screw lock screw piece, screwdriver head 11 joint rear sides are established to have the convenient hand of radian and holds lever, lever has the recessed striped of the weak point portion of several annular arrangements, and the recessed striped of several annular arrangements length portion is established in the appropriate location on short recessed groove rear lever side face can increase the contact friction, lever rear end tool concave ring groove 12, concave ring groove 12 is the depression ring-type;

The bulge loop 21 of the convex hoop shape that one revolving part, 20 tools cooperate makes it can be hubbed on the concave ring groove 12 of screwdriver 10.After the entire combination, as shown in Figure 2.

See also shown in Figure 3ly, be the utility model combination back profile, when being hubbed at revolving part 20 on the screwdriver 10 lever rear ends, the concave ring groove 12 of screwdriver 10 can match with the bulge loop 21 of revolving part 20.

When hand-screw moves screwdriver 10, the palm of the hand of hand can be pressed against on the revolving part 20, make screwdriver 10 have the strength of downward turn and the turn screw piece, because of revolving part 20 and screwdriver 10 are the meter shape that is pivoted, revolving part 20 can be done the rotation of 360 degree, promptly do not have relative motion between the revolving part 20 and the palm of the hand and produce, this is the design concept of the utility model screwdriver 10 ergonomics when turn, also is its advantage.

Please continue to consult Fig. 4 and shown in Figure 5, be the utility model second embodiment, a screw hole I 3 is set up in screwdriver 10 bottom radial positions, and set up a pivot hole 22 in appropriate location, revolving part 20 upper end, and set up a spiral shell spare 30, the position forms one and supports face 31 at the bottom of 30 of spiral shell spares, when combination, spiral shell spare 30 is passed pivot hole 22 screw locks of revolving part 20 in the screw 13 of screwdriver 10, the face 31 that supports of spiral shell spare 30 is abutted against on screwdriver 10, because of the face 31 that supports of spiral shell spare 30 has a height, so revolving part 20 is hubbed on the screwdriver 10.

Please continue to consult Figure 6 and Figure 7, be the utility model the 3rd embodiment, set up a card face 14 in screwdriver 10 bottoms, in the middle of revolving part 20, also have a pivot hole 22, when combination, the card face 14 of screwdriver 10 is compressed slightly, and card face 14 covers that the screw 22 of revolving part 20 aligns screwdriver 10 close, and this moment, revolving part 20 can be hubbed at the card face 14 of screwdriver 10.

Please continue to consult shown in Figure 8, be the utility model the 4th embodiment, this embodiment is opposite with the embodiment of Fig. 1, it is poroid in the concave ring groove 12 of screwdriver 10 is, and the bulge loop 21 of revolving part 20 promptly is and protrudes out shape 10, the bulge loop 21 of revolving part 20 holds to go in the concave ring groove 12 of screwdriver 10, and profile as shown in Figure 9.

Screwdriver 10 also can be had a register hole in tip side, and screwdriver head 11 is separately the register hole place that an element is sleeved on screwdriver 10 again, makes screwdriver I0 tool substitute the effect of screwdriver head 11.

The concave ring groove 12 of screwdriver 10 can have tooth or decorative pattern with the bulge loop 21 of revolving part 20 on its side face, so can omit the effect of tool location when revolving part 20 rotates on screwdriver 10.

The advantage that the utility model screwdriver 10 tool on structure is following:

Because of revolving part 20 and screwdriver 10 are the meter shape that is pivoted, when the moving screwdriver 10 of hand-screw, the palm of the hand of hand can be pressed against on the rotary body 20, make screwdriver 10 have the strength of downward turn and the turn screw piece, and revolving part 20 can be done the rotations of 360 degree.Promptly do not have relative motion between the revolving part 20 and the palm of the hand and produce, this is the design concept of the utility model screwdriver 10 ergonomics when turn, also is its advantage.

In sum, the utility model has novelty and practical effect concurrently, and can improve the shortcoming of commonly using, and really is a splendid creation.
