Description
Technical field
The utility model relates to a kind of screwdriver, and especially a kind of anti abrasive and head can carry out the screwdriver of 360 degree of rotary moveables.
Background technology
In the middle of daily life, usually use the various screw of screwdriver dismounting, screw is used in different local, and some is that some are apparent, and maneuverable region, some is the place for corner or secret, the especially instrument of some precisions.Existing screwdriver structure is fixed, and all structures are all point-blank, can only the screw on dismounting surface, and the screw in some corners or tiny place not easily contacts, and causes installation and removal relatively to bother.Certainly, China Patent No. CN 203208112U discloses one " directed screwdriver ", the crewdriver attachment of this screwdriver can be movable, but the connection pin of this screwdriver easily slides, and service time longer after, can cause connecting pin wearing and tearing, reduce life-span of screwdriver, comprehensive, lacking now one can all-directional rotation, and simple to operate, can anti abrasive screwdriver.
Utility model content
For deficiency of the prior art, the utility model provides a kind of screwdriver, and this screwdriver is wear-resistant, and can rotate freely, the screw in the tiny place of easy disassembly or corner place.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows:
The wear-resistant movable screwdriver that full angle rotates, comprises handle, support bar and crewdriver attachment, it is characterized in that being connected by bar bar rotational structure between described support bar, is connected between described crewdriver attachment and described support bar by head rod rotational structure;
Described bar bar rotational structure comprises lower spherical steel ball, midfoot support bar inner chamber, lower support bar inner chamber and lower circling ring, described lower circling ring surrounds and connects two parts support bar, wherein midfoot support bar inner chamber is located at upper support bar lower end, and lower support bar inner chamber is located at the upper end of lower support bar;
Described head rod rotational structure comprises spherical steel ball, upper support bar inner chamber, crewdriver attachment inner chamber and upper circling ring, described upper circling ring surrounds and connects epimere support bar and crewdriver attachment, wherein, upper support bar inner chamber is located at upper support bar upper end, and crewdriver attachment inner chamber is located at crewdriver attachment lower end.
Described upper support bar inner chamber, midfoot support bar inner chamber, lower support bar inner chamber and crewdriver attachment inner chamber are hemispherical.
Angle between described crewdriver attachment and upper support bar extended line and between upper support bar and lower support bar extended line can control between 0 ° to 60 °.
Described crewdriver attachment is provided with cutter head.
The model of described cutter head can be a word, cross, rice word, T-shaped, H type, L shape, T-shaped any one.
The utility model compared with prior art has following beneficial effect:
Screwdriver of the present utility model, by the rotation of two rotational structures, the conehead of screwdriver and support bar can be made freely movable, for some precision instruments, or the screw of comparatively complicated position carries out dismounting in construction, and rotational structure also can ensure that screwdriver is wear-resistant, adds the service life of screwdriver.And the utility model is simple to operate, easy to use.
Accompanying drawing explanation
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 two rotational structure profiles of the present utility model.
Detailed description of the invention
As shown in Figure 1, the wear-resistant movable screwdriver that a kind of full angle rotates, primary structure comprises handle 1, support bar 2 and crewdriver attachment 3, support bar is divided into two parts by a rotational structure, be upper support bar 201 and lower support bar 202 respectively, be connected by another rotational structure between support bar 2 and crewdriver attachment.In Fig. 2, connected by bar bar rotational structure between top 201 support bar and lower support bar 202, connected by head rod rotational structure between crewdriver attachment 3 and upper support bar 201.Concrete structure is:
In bar bar rotational structure, circling ring 701 under being of a main connection function, it comprises to live in portion's support bar 201 and lower support bar 202, and, upper support bar 201 lower end is provided with midfoot support bar inner chamber 9, lower support bar 202 upper end is provided with lower support bar inner chamber 10, and centre is provided with the lower spherical steel ball 501 can supporting to rotate, midfoot support bar inner chamber 9 and lower support bar inner chamber 10 are hemispherical shape, midfoot support bar inner chamber 9 and lower support bar inner chamber 10 are agreed with lower spherical steel ball 501, obtains sufficient lubrication.
In head rod rotational structure, what mainly play connection function is upper circling ring 702, it comprises to live in portion's support bar 201 and crewdriver attachment 3, further, upper support bar 201 upper end is provided with upper support bar inner chamber 8, and crewdriver attachment 3 lower end is provided with crewdriver attachment inner chamber 6, and centre is provided with the upper spherical steel ball 502 can supporting to rotate, upper support bar inner chamber 8 and crewdriver attachment inner chamber 6 are hemispherical shape, upper support bar inner chamber 8 and crewdriver attachment inner chamber 6 are agreed with upper spherical steel ball 502, obtains sufficient lubrication.
The extended line of crewdriver attachment 3 and upper support bar 201 and the angle between upper support bar 201 and lower support bar 202 extended line can be made can to control between 0 ° to 60 ° by rotational structure, morely in life select 45 ° for preferred version.
Certainly, crewdriver attachment 3 is provided with cutter head 4, and the model of cutter head 4 can be a word, cross, rice word, T-shaped, H type, L shape, T-shaped any one, general multiselect one word and cross.
