Abstract
The utility model relates to a hand-operated tool, in particular to a high-strength wrench. The high-strength wrench comprises a ratchet body and a wrench rod. The ratchet body is arranged on the head portion of the wrench rod. A ratchet is arranged inside the ratchet body. A through hole is formed in the middle of the ratchet. The through hole is a quadrilateral through hole. The height of the quadrilateral through hole is smaller than the thickness of the ratchet. A covering plate is arranged on the ratchet body. Countersunk screws are arranged on the covering plate. A pawl is arranged on the connection between the ratchet body and the wrench rod. One end of the pawl is connected with the ratchet. The other end of the pawl is connected with one end of a spring. The other end of the spring is connected with an adjusting screw. Due to the fact that the quadrilateral through hole is adopted, the thickness of the ratchet body is reduced, the high-strength wrench can be used in a narrow occasion, and an application range of the high-strength wrench is enlarged. Due to the fact that the ratchet and the pawl are connected, the strength of the high-strength wrench is improved, the high-strength wrench is prevented from damage when the high-strength wrench is used under large power, and performance of the high-strength wrench is improved.
Description
Technical field
The utility model relates to a kind of hand-operated tools, is specifically related to a kind of high strength 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, ratchet portions of the prior art can be stretched out cover plate, and in actual use in narrow environment, ratchet wheel body is blocked up can to produce awkward problem.
The utility model content
Technical problem to be solved in the utility model provides a kind of high strength spanner and solves in the prior art because the blocked up meeting of ratchet wheel body produces inconvenience and the little problem of the scope of application used.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: comprise ratchet wheel body and tommy bar, described ratchet wheel body is arranged on the head of tommy bar, be provided with ratchet in the described ratchet wheel body, be provided with through hole in the middle of the described ratchet, described through hole is the quadrangle through hole, the height of described quadrangle through hole is less than the thickness of ratchet, described ratchet wheel body is provided with cover plate, described cover plate is provided with sunk screw, described ratchet wheel body and described tommy bar junction are provided with ratchet, one end of described ratchet is connected with ratchet, and the other end of described ratchet is connected with an end of spring, and the other end of described spring is connected with adjustment screw.
Further, described cover plate is fixedlyed connected by sunk screw with ratchet wheel body.
Further, described spring is the compression spring.
The beneficial effects of the utility model are: by quadrangle through hole in using, attenuate the thickness of ratchet wheel body, in narrow occasion, also can use spanner, increased the scope of application of spanner, by using the mode of ratchet and pawl tabling, improve the intensity of spanner, can use bigger strength twisting spanner and spanner is damaged, improved the performance of spanner.
