Abstract
The utility model discloses the screwdriver of being convenient to rotatable handgrip firmly, comprise handle, support bar and crewdriver attachment, between support bar and handle, connect by rotational structure, wherein, rotational structure comprises a spherical steel ball, support bar inner chamber, intracavity of handle and circling ring, circling ring surrounds and connects support bar and handle, and support bar inner chamber and intracavity of handle are hemispherical, and the angle between support bar and handle extended line can be controlled between 0 ° to 60 °.The utility model is simple to operate, easy to use, support bar and handle at an angle after, increased the frictional force between hand and handle, can also ensure that on this basis screwdriver normally twists, carry out the handling of screw.
Description
Technical field
The utility model relates to a kind of screwdriver, and especially a kind of anti abrasive and handle can be rotated movable screwdriver, and this screwdriver can increase the frictional force between hand and handle.
Background technology
In the middle of daily life, usually use the various screws of screwdriver dismounting, screw uses different local, and some is that some are apparent, and maneuverable region, and some is for corner or concealed place, especially some accurate instruments.Existing screwdriver structure is fixed, and all structures are all point-blank, screw that can only dismounting surface, and the screw in some corners or tiny place is difficult for contact, causes installation and removal relatively to bother.And what the screwdriver of straight rod-shaped leaned in exerting oneself is the frictional force between staff and screwdriver handle, if screwdriver is longer service time, or when having otherwise reason, the frictional force between hand and screwdriver handle reduces, and when also can causing using screwdriver, is inconvenient to exert oneself.Comprehensive, lacking now one can be rotated, and increases the novel screwdriver of frictional force between hand and screwdriver handle.
Utility model content
For deficiency of the prior art, the utility model provides a kind of screwdriver, and this screwdriver is wear-resistant, and handle can rotate freely, and facilitates hand firmly, and screw that can dismounting corner place.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows:
The screwdriver of being convenient to rotatable handgrip firmly, comprises handle, support bar and crewdriver attachment, it is characterized in that connecting by rotational structure between described support bar and described handle.
Described rotational structure comprises a spherical steel ball, support bar inner chamber, intracavity of handle and a circling ring, and described circling ring surrounds and connects described support bar and described handle.
Described upper support bar inner chamber, lower support bar inner chamber, crewdriver attachment inner chamber and intracavity of handle are hemispherical.
Angle between described support bar and described handle extended line can be controlled between 0 ° to 60 °.
The utility model compared with prior art has following beneficial effect:
Screwdriver of the present utility model, handle can rotate freely, and after rotation, between handle and support bar, at an angle, can increase the frictional force between hand and screwdriver, facilitates hand firmly.And rotational structure also can ensure can normally twist after the anglec of rotation, handling screw.
Brief description of the drawings
Below in conjunction with accompanying drawing and embodiment, the utility model is described further.
Fig. 1 is cross-sectional view of the present utility model;
Fig. 2 is rotational structure profile of the present utility model.
Detailed description of the invention
As shown in Figure 1, 2, a kind of screwdriver of being convenient to rotatable handgrip firmly, primary structure comprises handle 1, support bar 2 and crewdriver attachment 4, and the rotational structure 3 of connecting handle and support bar, rotational structure comprises a spherical steel ball 301, support bar inner chamber 303, intracavity of handle 304 and surrounds the circling ring 302 that is connected support bar inner chamber 303 and intracavity of handle 304.
Support bar inner chamber 303, intracavity of handle 304 are hemispherical, and each chamber and spherical steel ball 301 are agreed with, and obtain sufficient lubrication.
Angle between support bar and handle extended line can be controlled between 0 ° to 60 °, morely selects 45 °.
When use, the cutter head on crewdriver attachment 4 embeds in screw, is rotated.If desired more energetically time, for increasing friction force, firmly the rotational structure between handle and support bar is rotated, changes into after certain angle (being generally 45 °), twisting handle, drives support bar rotation, reaches the object of twisting handling screw.
The above is only the preferred embodiment of the invention; be noted that for those skilled in the art; not departing under the prerequisite of principle of the present invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
Claims (3)
