Abstract
The utility model relates to a manual tool, in particular to a high-strength rachet wrench. The high-strength rachet wrench comprises a rachet body and two wrench rods. The rachet body is arranged on the head portions of the two wrench rods, the rachet body is provided with a cover plate, and a rachet wheel is arranged inside the rachet body. A sunk screw is arranged on the cover plate, pawls are arranged at the connecting positions of the rachet body and the wretch rods, the pawls are connected with one ends of springs, and the other ends of the springs are connected with adjusting screws. The cover plate is fixedly connected with the rachet body through the sunk screw, the included angle between the two wrench rods is 15 degrees to 180 degrees, the included angle between the two wrench rods is 90 degrees to 180 degrees, and the included angle between the two wrench rods is 180 degrees. The two wrench rods are used in a place where high-strength fastening is needed, meanwhile, the two wrench rods are rotated to generate torque which is large enough to fasten a workpiece, the torque of the rachet wrench is improved, and the application range of the rachet wrench is widened.
Description
Technical field
The utility model relates to a kind of hand-operated tools, is specifically related to a kind of high strength ratchet spanner.
Background technology
Spanner is a kind of instrument of present people extensive use in productive life, ratchet spanner generally is made up of tommy bar and the ratchet wheel body that is arranged on the tommy bar head in the prior art, during use, the wrench body of holding with a firm grip afterbody, firmly the rotary spanner body gets final product then, yet in narrow environment, need in actual use in the fastening workpiece of high strength because the limited length of tommy bar can not produce enough torsion and reach fastening requirement.
The utility model content
Technical problem to be solved in the utility model provides that a kind of high strength ratchet spanner solves in the prior art because the limited length of tommy bar, can not produce the problem of enough torsion.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of high strength ratchet spanner, comprise ratchet wheel body and two tommy bars, described ratchet wheel body is arranged on the head of two tommy bars, described ratchet wheel body is provided with cover plate, be provided with ratchet in the described ratchet wheel body, described cover plate is provided with sunk screw, and described ratchet wheel body and each described tommy bar junction are provided with ratchet, described ratchet connects an end of spring, and the other end of described spring is connected with adjustment screw.
The beneficial effects of the utility model are: using two tommy bars, rotate two tommy bars simultaneously in needing the fastening occasion of high strength, workpiece is carried out fastening to produce enough big torsion, improved the torsion of ratchet spanner, increased the scope of application of ratchet spanner.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described cover plate is fixedlyed connected by sunk screw with ratchet wheel body.
Further, the angle between described two tommy bars is that 15 degree are to 180 degree
Further, 90 degree of the angle between described two tommy bars, 180 degree
Further, 180 degree of the angle between described two tommy bars.
Adopt the beneficial effect of above-mentioned further scheme to be: according to the needs of different environments for use, the different angle of two tommy bars can be set, further strengthen the scope of application of ratchet spanner.
