Abstract
The invention discloses a kind of double end re-entrant angle fork spanner, its structure includes handle and driving end；The driving end is provided with two, and described two driving ends are located at the two ends of the handle；Pull for two on the driving end and be provided with the inside of lip symmetrical two re-entrant angles.The angle of the re-entrant angle is 120 degree.The beneficial effects of the invention are as follows：Bolt firm grip can more be damaged re-entrant angle the corner angle of bolt without skidding.
Description
Technical field
The present invention relates to a kind of spanner, more particularly to a kind of double end re-entrant angle fork spanner.
Background technology
As depicted in figs. 1 and 2, the inner side of the jaw of traditional double end fork spanner is straight structure, and the shortcoming of this spanner is that the corner angle of nut are damaged rounding by jaw with only two faces of contact surface of screw or nut so as to be easily caused.
The content of the invention
Problem to be solved by this invention is to provide a kind of double end re-entrant angle fork spanner, and its jaw during nut is twisted has four faces so as to damage the corner angle of nut with the stress surface of nut.
In order to solve problem above, technical scheme is as follows：
A kind of double end re-entrant angle fork spanner, its structure includes handle and driving end；The driving end is provided with two, and described two driving ends are located at the two ends of the handle；Pull for two on the driving end and be provided with the inside of lip symmetrical two re-entrant angles.
The angle of the re-entrant angle is 120 degree.
The beneficial effects of the invention are as follows：Bolt firm grip can more be damaged re-entrant angle the corner angle of bolt without skidding.
Brief description of the drawings
Fig. 1 is the structural representation of traditional fork spanner.
Structural representation when Fig. 2 is Fig. 1 grip bolts.
Fig. 3 is the structural representation of the embodiment of the present invention.
Structural representation when Fig. 4 is Fig. 3 grip bolts.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples：
As shown in Figure 3 and Figure 4, its structure of the invention includes handle 1 and driving end；Driving end is provided with two, and two driving ends are located at the two ends of handle 1；Pull for two on driving end and be provided with the inside of lip symmetrical two re-entrant angles 20.The angle of re-entrant angle 20 is 120 degree.
As shown in Figures 1 to 4, the embodiment of the present invention is with the difference of traditional monkey wrench：
Two inner sides for pulling lip of traditional fork spanner are straight structure, and are designed with re-entrant angle 20 on two inner sides for pulling lip on embodiments of the invention.The periphery of bolt is the structure of hexagon, traditional fork spanner by the bolt of hexagon be clamped in two pull between lip when six of bolt contacted with fork spanner when there was only two and stress, and the outer of bolt 3 is with four sides and is contacted with the embodiment of the present invention and stress during embodiment of the present invention grip bolt 3, thus the embodiment of the present invention more can will not skid and damage the corner angle of bolt 3 by the firm grip of bolt 3 and when turning bolt 3 because loosening.
