Abstract
The invention belongs to a manual tool, and particularly relates to an anti-slipping open spanner, which comprises a spanner body. A spanner head is arranged at the front end of the spanner body, a handle is disposed at the rear end of the spanner body, a concave groove is disposed on the spanner head, surfaces along two inner sides of an opening of the concave groove form clamping surfaces of a workpiece, and bumps are disposed on the clamping surfaces. When the handle rotates, distances among the bumps on the clamping surfaces and contact points of the workpiece are smaller than the length of a single side of the workpiece, and the bumps on the clamping surfaces are positioned within contact surfaces of the workpiece; and when the workpiece rotates, the bumps of the clamping surfaces are always positioned on surfaces between two corners of the workpiece but do not contact with the corners of the workpiece. Accordingly, the problem of slipping of a solid spanner is fundamentally solved, and operational safety is improved.
Description
Technical field
The invention belongs to a kind of hand-operated tools, relate in particular to a kind of anti-skidding open-end wrench.
Background technology
Open-end wrench is one of instrument that the most generally uses in the hand-operated tools, and the operator can select for use with the open-end wrench of the corresponding specification of its size according to the nut of different specification size and manipulate.The parallel mode of the most employings of the clamping face of existing open-end wrench; Be very easy to hurt the surface of bolt or nut when swivel bolt or the nut with the open-end wrench of this fit system manufacturing; Skid easily; Operate dangerous; Because the design of the opening size of open-end wrench must cause open-end wrench when rotational workpieces, to have only two points of clamping face to act on respectively on two angles of workpiece greater than workpiece size, bolt after being rotated or nut angle are bound to receive damage in various degree in the practical operation.If the part that clamping face is contacted with workpiece is avoided the angle of workpiece, so just can fundamentally solve the problem of skidding and damaging workpiece.
Summary of the invention
In order to overcome the deficiency of existing open-end wrench; The invention provides a kind of anti-skidding open-end wrench; This anti-skidding open-end wrench has not only kept the function of existing open-end wrench, and when swivel bolt or nut, skidding can not take place, and clamping is firm; Can not damage the angle of bolt or nut, handling safety is reliable.
For realizing above-mentioned purpose, the present invention has adopted following technical scheme: a kind of anti-skidding open-end wrench, and said spanner is formed by pulling body; The front end of pulling body is a spanner; The rear end of pulling body is a handle, and Baltimore groove is arranged on the spanner, the clamping face that to be positioned at two relative faces of Baltimore groove are workpiece; It is characterized in that said clamping face is provided with convexity.
Said convexity, when rotational workpieces, the wire length of convexity on each clamping face and workpiece contact point is less than the monolateral length of workpiece.
Said convexity, when rotational workpieces, the position of each clamping face raising is positioned in the workpiece contact-making surface scope.
Said Baltimore groove runs through spanner.
Anti-skidding open-end wrench of the present invention and existing up-to-date open-end wrench compared with techniques, it is simple to possess skills, and processes characteristics easily, has fundamentally solved the skidding of open-end wrench, has prolonged the service life of nuts and bolt, has improved the security of operation.
Below in conjunction with accompanying drawing and embodiment the present invention is made further detailed description.

The specific embodiment
Embodiment 1:
A kind of anti-skidding open-end wrench embodiment, referring to Fig. 1 to Fig. 5, as shown in Figure 1; Said spanner by pull body 1, spanner 2 is formed, the front end of pulling body is a Baltimore groove 101, the rear end of pulling body is a handle 102; Clamping face 201 and 202 are arranged on the spanner, have protruding 301,302,303,304 above the clamping face.
As shown in Figure 2; What is 403 vertical with 304 curved surface arc core line 402 with 302 with 303 for the center line 401 that extends downward concave curvatures along the Baltimore groove opening part and clamping face curved protrusion 301; Simultaneously, center line 401 is parallel with 405 with 304 curved surface arc core line 404 with 303 with 302 with curved protrusion 301.
The size of the said anti-skidding open-end wrench of present embodiment is 16mm, and the radian that is positioned at the curved protrusion on the piece-holder face is R1.5mm, curved surface height 1.5mm, nut specification 16mm.
As shown in Figure 3; Hex nut 3 is placed between two clamping faces of said spanner; This moment said clamping face the summit 501 and 502 of curved protrusion between air line distance less than the length of side 505 of hex nut, the air line distance between curved protrusion 303 and 304 the summit 503 and 504 is less than the length of side 505 of hex nut.
As shown in Figure 4, when along direction L switching handle 102, the curved protrusion summits 501 that only are positioned at clamping face 201 and 202 surfaces contact the surface at nut with 504, and they can not touch two the angle A and the B of nut all the time.
As shown in Figure 5, when along direction R switching handle 102, the curved protrusion summits 502 that only are positioned at clamping face 201 and 202 surfaces contact the surface at nut with 503, and they can not touch two the angle C and the D of nut all the time.
Embodiment 2:
This is an another kind of structure of the present invention; As shown in Figure 6; Identical described in its function and the embodiment 1; Be with difference described in the embodiment 1, when rotary handle 102, be arranged in the curved protrusion summit 501,502,503 and 504 that the summit of facing directly on protruding 601 and 602 and 603 and 604 701,702,703 and 704 has substituted embodiment 1.
Embodiment 3:
Be another kind of structure of the present invention; As shown in Figure 7; Identical described in its function and the foregoing description, be that with above-mentioned two embodiment differences the convexity on each clamping face is 1; When rotary handle 102, be arranged in the curved protrusion summit 501,502,503 and 504 that the summit of facing directly on protruding 801 and 802 901,902,903 and 904 has substituted embodiment 1.
