Abstract
The utility model relates to a wrench which belongs to the field of hand-operated tools, in particular to a wrench. The section of the end part of the wrench is a polygon, and the edges are in a concave-inward arc shape, and the angle formed by two edges is in a concave-outward arc shape; and the end part can be bent to be an L shape. The wrench has simple structure, easy operation and strong rotating force, and is the wrench which can not cause the hand sliding easily.
Description
Technical field
The utility model spanner belongs to the hand-operated tools field.Particularly relate to a kind of spanner.
Background technology
Using now the spanner on endoporus, all is 4 square, and the employing polygon is also arranged, because the sideline is a straight line, the angle of formation is big, and rotatory force is little, and causes slip easily, and loses rotatory force.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art part, and provides a kind of rotatory force big, and the angle of formation is big, is not easy to cause the spanner of slip.
The purpose of this utility model reaches by following measure, the end cross-sectional of spanner is polygonal, the limit is the arc that concaves, the angle that both sides form is cambered outwards arc, because the arc that the limit concaves, the angle that forms is big, and the angle that both sides form is cambered outwards arc, is not easy to cause the slip that loses rotatory force.
The end cross-sectional of spanner of the present utility model is a hexagon, and the limit is the arc that concaves, and the angle that both sides form is cambered outwards arc, forms hexagram.
The end cross-sectional of spanner of the present utility model is a blossom type, and the limit is the arc that concaves, and the angle that both sides form is cambered outwards arc, forms blossom type.
The end cross-sectional at spanner of the present utility model two ends is polygonal, and the limit is the arc that concaves, and the angle that both sides form is cambered outwards arc.
The end of spanner of the present utility model can bending, forms the L type, end bending that also can two ends.
Spanner of the present utility model end can an end be a cross bar, forms the T type, and the end cross-sectional of cross bar is polygonal, and the limit is the arc that concaves, and the angle that both sides form is cambered outwards arc.
The utility model is simple in structure, and is easy to use, and rotatory force is big, is a kind of spanner that is not easy to cause slip.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is side schematic views of accompanying drawing 1.
Accompanying drawing 3 is the diagrammatic sketch of facing upward of accompanying drawing 2.
Accompanying drawing 4 is end cross-sectional enlarged diagrams of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, the end bending of an end of the utility model spanner forms the L type, and the end cross-sectional at the two ends of spanner is a hexagon, and the hexagon limit is the arc that concaves, and the angle that both sides form is cambered outwards arc.
As shown in Figure 4, the end cross-sectional at the two ends of the utility model spanner is a hexagon, and the hexagon limit is the arc that concaves, arc radius RE is between 0.2mm-3mm, the angle that both sides form is cambered outwards arc, and arc radius RF is between 0.05mm-1.2mm, and it is star-like to form hexagonal.
