Abstract
The utility model discloses an open jaw type wrench which comprises an upper jaw clamp 2 and a lower jaw clamp 3. The opposite sides of the upper jaw clamp 2 and the lower jaw clamp 3 are respectively provided with a parallel wrenching surface 4 which is intersected with a main body 1 to form a throat cavity 6 which has an intersection angle 7. The wrenching surfaces 4 of the upper jaw clamp 2 and the lower jaw clamp 3 are respectively provided with a convex wrenching region 5 which is approximately convex from the wrenching surfaces 4 of the upper jaw clamp 2 and the lower jaw clamp 3. In this way, the force application contacting point of a screw cap and the wrench is transferred at one side edge plane of the screw cap and one angle of the screw cap. When the utility model is operated, the side angle of the screw nut is prevented from being wearing, and the phenomena of locking, disassembling and slipping are also prevented.
Description
The utility model relates to a kind of manual operations spanner, especially a kind of open-end wrench of pulling hexagonal (hexagon)nut.
Open-end wrench is a kind of instrument commonly used, and the open-end wrench that uses has two jaws at present, and it respectively comprises a plane face of pulling.Two pull the face almost parallel and form betwixt one just can a ccontaining nut opening shape larynx cave so that allow a nut enter in the larynx cave by the openend in larynx cave, the side that this two face of pulling that parallels of mat is pulled nut.Slip in this larynx cave for ease of nut, two pull the distance between two parallel side that in fact distance between face be slightly larger than nut.Therefore, when pulling nut, the face of pulling is not into parallel face with pane and contacts with face, but becomes an angle of inclination to be contacted with near the nut bight actual.This kind way of contact is easy to cause the bight of nut to be damaged (being sphering).
It is a kind of when lock unloads nut that the purpose of this utility model is to provide, the open-end wrench at nut not easy to wear angle.
In order to address the above problem, the technical solution of the utility model is: a kind of open-end wrench, comprise upper and lower jaw, the opposite side of upper and lower jaw has the parallel face of pulling respectively, two pull face intersects a larynx cave that angle arranged in body, the pulling of upper and lower jaw is respectively equipped with projection and pulls the district on the face, projection is pulled the district respectively from the face of pulling of upper and lower jaw projection and be positioned at its central authorities slightly.
Good effect of the present utility model has: pull the district because the face of the pulling middle body of upper and lower jaw all is provided with projection, and form an angle on the larynx cave; Therefore, the application of force contact point of nut and spanner is transferred to the side plane and a certain angle of nut of nut, and then when operation, has prevented that the nut corner from wearing and tearing and the phenomenon of unloading slippage is locked in generation.
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is a schematic appearance of the present utility model.
Fig. 2 is a floor map of the present utility model.
Fig. 3 is the plane enlarged drawing of jaw under the utility model.
Embodiment: referring to Fig. 1, Fig. 2, Fig. 3, a kind of open-end wrench, comprise upper and lower jaw 2,3, the opposite side of upper and lower jaw 2,3 has the parallel face of pulling 4 respectively, pull be respectively equipped with on the face 4 projection pull the district 5, it is slightly protruding from the face of pulling 4 of upper and lower jaw 2,3 respectively that projection is pulled district 5, and be positioned at the central authorities that jaw is pulled face 4; Projection is pulled half that district's length of 5 is about the nut length of side, and during with the nut compounding practice, just is positioned at the central authorities of the nut length of side; Pull face 4 and intersect a larynx cave 6 that angle 7 arranged in body 1, during operation, a certain angle of nut places angle 7; Two projectioies are pulled the distance that the distance of distinguishing 5 equals nut two relative parallel edges.According to design of the present utility model, when pulling nut, nut is difficult for producing sphering.
