Abstract
The utility model discloses a pentagonal hammering spanner, which comprises a handle (1). A limiting hole (2) with a regularly pentagonal cross section is arranged at one end of the handle (1), and a hammering head (3) is disposed at the other end of the handle (1). Accordingly, the problem that external pentagonal screws cannot fittingly rotate with tools in the prior art is resolved. Besides, when the pentagonal hammering spanner is used with an external pentagonal screw, the screw and the spanner cannot relatively slip easily. The pentagonal hammering spanner further can be used for knocking and 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 five jiaos of striking wrench.
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: provide a kind of and cooperate outer pentagonal screw use and have five jiaos of striking wrench that knock function.
Technical solution adopted in the utility model is: a kind of five jiaos of striking wrench, and it comprises handle, and handle one end is provided with the spacing hole that a cross section is regular pentagon, and the other end of handle is provided with the hammering head.
The beneficial effects of the utility model are: five jiaos of striking wrench of the utility model, and pinch bar one end is 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, five jiaos of striking wrench of the utility model can also be used to knock.
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, 3. hammering head.
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 five jiaos of striking wrench of the utility model, it comprises handle 1, handle 1 one ends are provided with the spacing hole 2 that a cross section is regular pentagon.The spacing hole 2 of five jiaos of striking wrench 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 five jiaos of striking wrench of the utility model cooperate with outer pentagonal screw and are difficult for skidding.In addition, in the actual use, in the time of need beaing, existing spanner does not all knock function, and five jiaos of striking wrench of the utility model just have hammering 3, and described hammering 3 longitudinal section are trapezoidal shape, in conjunction with Fig. 1, Fig. 2.Hammering 3 can be used for beaing, and the scope of application is wider.
Claims (1)
1. five jiaos of striking wrench, it is characterized in that: it comprises handle (1), and handle (1) one end is provided with the spacing hole (2) that a cross section is regular pentagon, and the other end of handle (1) is provided with hammering head (3).
