Abstract
The invention relates to a novel wrench. The novel wrench is characterized in that an upper layer and a lower layer inside a jaw opening are provided with the snapping faces which are sawtooth faces, and the sawtooth faces of the upper layer and the lower layer are meshed with each other. The novel wrench is simple in structure and convenient to operate. The snapping faces are arranged inside the jaw opening of the wrench, so that large friction force is produced between a bolt and the jaw opening of the wrench in the bolt pulling process of the wrench, a slipping phenomenon can be prevented, normal working can be further ensured, and the working efficiency and working convenience are greatly improved by adopting the novel wrench.
Description
Technical field
The present invention relates to a kind of spanner, especially relate to a kind of Novel socket wrench of skidding of preventing, belong to metal fittings technical field.
Background technology
Spanner is in our daily life and production, apply very extensive, the spanner of traditional stubborn bolt comprises handle and jaw, the width of described jaw is consistent with the width for the treatment of stubborn bolt, but, because spanner and bolt generally are metalwork, therefore,, after the jaw of spanner is nested on bolt, between jaw and bolt, still there is certain space, therefore, in rotary spanner, because the frictional force between jaw and bolt is inadequate, the phenomenon that is easy to skid, thereby cannot turn smoothly bolt, increase work difficulty.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of simple in structure, prevent a kind of Novel socket wrench of skidding.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of Novel socket wrench, comprises jaw and handle, it is characterized in that, the upper and lower two-layer occlusal surface that is provided with in inside of described jaw, described occlusal surface is serrated face, and described upper strata serrated face and lower floor's serrated face intermeshing.
Further, described serrated face and jaw are one-body molded.And the material of described serrated face is metal.
The invention has the beneficial effects as follows: the present invention is simple in structure, easy to operate, by the jaw inside at spanner, occlusal layer is set, make spanner in the process of wrenching bolt, can make the larger frictional force of generation between bolt and the jaw of spanner, prevent that skidding from occurring, and then guarantee normally the carrying out of work, the present invention has improved the convenience of operating efficiency and work greatly.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the invention.
In figure, main Reference numeral implication is:
1, handle 2, jaw 3, occlusal surface.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be described in detail.
Fig. 1 is the structural representation of one embodiment of the invention.
As shown in Figure 1: Novel socket wrench, comprise jaw 2 and handle 1, the upper and lower two-layer occlusal surface 3 that is provided with in the inside of described jaw 2, described occlusal surface 3 is serrated face, and described upper strata serrated face and lower floor's serrated face intermeshing.Described serrated face and jaw 2 are one-body molded, and the material of described serrated face is metal.
The present invention is simple in structure, easy to operate, by jaw 2 inside at spanner, occlusal layer 3 is set, make spanner in the process of wrenching bolt, can make to there is larger contact area between the jaw 2 of bolt and spanner, can produce larger frictional force, prevent the generation of skidding, and then guaranteeing normally the carrying out of work, this has improved the convenience of operating efficiency and work greatly.
Above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
Claims (3)
