Abstract
The utility model discloses a double pentagonal spanner, which comprises a handle (1), wherein a limiting hole (2) with a pentagonal section is respectively arranged at two ends of the handle (1), thereby solving a problem that no tool can be matched with pentagonal screws to rotate in the prior art. Further more, when the single pentagonal spanner is matched with the pentagonal screws to be used, slipping is not easy to happen between the screw and the spanner. The single pentagonal spanner belongs to the technical field of fasteners.
Description
Technical field
The utility model belongs to technical field of fastening, especially relates to a kind of two five jiaos of spanners.
Background technology
Screw of the prior art generally comprises head and bar portion, head and bar portion are connected as a single entity, head is provided with outer-hexagonal outward, frequently be screwed into especially or the occasion of the screw of back-outing for needs, there is following technological deficiency in the screw of said structure: most outer-hexagonal screws be screwed into back-out can image be interpreted as that two pull the symmetrical both sides of clamping the outer-hexagonal screw, rotate when pulling by two folders then and drive screw and rotate.The application of force on the external hex(agonal)screw of this mode only acts on wherein two angles of outer-hexagonal screw, under the bigger situation of the application of force, skids easily between instrument and the screw, and screw is easily twisted bad.Therefore, the inventor of this patent has designed the outer pentagonal screw that is difficult for skidding when a and instrument rotates together, and patent applied for.Yet do not have the instrument that is used with outer pentagonal screw in the market.So the inventor determines to design the spanner that the outer pentagonal screw of a cooperation uses.
The utility model content
Technical problem to be solved in the utility model is: a kind of two five jiaos of spanners that cooperate outer pentagonal screw to use are provided.
Technical solution adopted in the utility model is: a kind of two five jiaos of spanners, and it comprises handle, the handle two ends respectively are provided with the spacing hole that a cross section is regular pentagon.
The beneficial effects of the utility model are: the two five jiaos of spanners of the utility model, and the pinch bar two ends respectively are provided with a spacing hole that is used with outer pentagonal screw, and therefore can solve does not have instrument to cooperate the problem of rotating with outer pentagonal screw in the prior art.In addition, when the utility model is used with outer pentagonal screw, be difficult between the screw wrench skidding.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure, 1. handle, 2. spacing hole.
The specific embodiment
Below be the utility model preferred embodiment, but therefore do not limit protection domain of the present utility model.
With reference to Fig. 1, shown in Figure 2, a kind of embodiment of the two five jiaos of spanners of the utility model, it comprises handle 1, handle 1 two ends respectively are provided with the spacing hole 2 that a cross section is regular pentagon.The spacing hole 2 of two five jiaos of spanners matches with outer pentagonal screw during use, can drive screw and rotate, because the utility model spacing hole 2 cross sections are regular pentagon, is different from hexagon, does not therefore have symmetrical limit.When cooperating outer pentagonal screw with the utility model, the Wai Wujiao on the outer pentagonal screw head has at least four angles stressed.Therefore the two five jiaos of spanners of the utility model cooperate with outer pentagonal screw and are difficult for skidding.
Claims (1)
1. two five jiaos of spanners, it is characterized in that: it comprises handle (1), handle (1) two ends respectively are provided with the spacing hole (2) that a cross section is regular pentagon.
