Specific implementation mode
The utility model is described in detail below in conjunction with the accompanying drawings.
A kind of screwdriver, as shown in Figure 1, include being screwed by handle 1 with the handle 1 and cutter head 2 for facilitating gripping,
Band dynamic cutter head 2, by screw tightening or unscrews.In conjunction with reference to Fig. 2, warp architecture 3 is provided between handle 1 and cutter head 2, one
A little narrow places, are especially in the presence of the position of barrier, are allowed between cutter head 2 and handle 1 and are bent centainly by warp architecture 3
Angle, and then it is more convenient when screwing.Wherein, warp architecture 3 include the bulb 31 being connect with handle 1 and be set to
Spherical groove 32 on cutter head 2, by bulb 31 in spherical groove 32, and the rotation in spherical groove 32 of bulb 31.In order to allow bulb
31 can drive spherical groove 32 to carry out axial rotation, and restricted cutter head 2 is arranged between spherical groove 32 and bulb 31 and exists with handle 1
The limiting structure 4 mutually rotated occurs for its axis direction.
Wherein, as shown in Figures 2 and 3, limiting structure 4 includes the convex block 41 being arranged in spherical groove 32 and is opened in ball
Strip groove 42 on first 31, the plane that opens up direction formation and the axis of handle 1 of the strip groove 42 along 31 surface of bulb are pressed from both sides
Angle is less than 90 degree, by the cooperation of convex block 41 and strip groove 42, allow the fluctuation of bulb 31 carry the cutter head 2 of strip groove 42 into
Row rotation.Strip groove 42 and convex block 41 can also be replaced mutually, i.e., the strip groove 42 in spherical groove 32, on bulb 31
Convex block 41 is opened up, and strip groove 42 is less than along the plane for opening up direction formation and the axis angle of cutter head 2 of slot inner surface
90 degree.Strip groove 42 is arranged to section into semi-circular structure, and convex block 41 is arranged to arc block structure, in convex block 41
During coordinating with strip groove 42, the combination of strip groove 42 and convex block 41 is rounder and more smooth, more convenient when to slide.
In order to facilitate the bending of handle 1 and cutter head 2, as depicted in figs. 1 and 2, it is arranged in the position that bulb is connect with handle 1
There is arc groove 5, the notch setting camber bulge loop 6 of spherical groove 32, arc bulge loop 6 matches with arc groove 5, arc bulge loop
6 are placed in arc groove 5, make it rounder and more smooth in rotation, and then when bulb 31 rotates, the notch of spherical groove 32 will not be light
The angle of its rotation is easily limited, and it is more convenient by the cooperation of arc groove 5 and arc bulge loop 6 it can be rotated.
