Abstract

A wrench base structure comprises a positioning stage and an outward-spreading arm. The positioning stage and the outward-spreading arm are formed with positioning holes and restricting holes respectively. One end of the outward-spreading arm is connected to the positioning stage by an elastic section, and the elastic section keeps the outward-spreading arm being slanted outward at a predetermined angle. By such arrangements, the force of the outward-spreading arm returning the inclined outward-spreading angle is utilized to make the restricting holes stagger with the positioning holes of the positioning stage and position the wrench which is inserted through both the restricting hole and the positioning hole. Further, it can reduce the cost of production.

Claims

1. A wrench base structure comprising a positioning stage and an outward-spreading arm and being equipped with a plurality of wrenches for use;

characterized in that;

the positioning stage is formed with a plurality of through positioning holes, and a shape of the positioning hole corresponds to a shape of a cross section of a handle of the wrench, the positioning stage is further formed with a protruding stopping block at one end of a plane thereof, an outer end of the outward-spreading arm is located opposite the protruding stopping block;

the outward-spreading arm is connected to one end of the positioning stage by an elastic section, and the outward-spreading arm is connected to the positioning stage to form a ∠

-shaped structure with an angle, the outward-spreading arm is formed with a plurality of restricting holes, when the outward-spreading arm is in a free outward spreading state, the restricting holes and the positioning holes are staggered with each other, when the outward-spreading arm is pressed down to cause deformation of the elastic section and a reduction of the angle, the restricting holes and the positioning holes are aligned with each other.

2. The wrench base structure as claimed in claim 1, wherein the outward-spreading arm, the elastic section and the positioning stage are integrally formed together, and the outward-spreading arm is integrally connected to the positioning stage by the elastic section.

3. The wrench base structure as claimed in claim 2, wherein the positioning stage is provided with the plane formed with a plurality of linearly arranged through positioning holes, the outward-spreading arm is integrally connected to the other end of the plane of the positioning stage by the elastic section and formed with a plurality of linearly arranged restricting holes, shapes and sizes of the restricting holes are larger than that of the positioning holes.

8. The wrench base structure as claimed in claim 1, wherein the outward-spreading arm, the elastic section and the positioning stage are independent structures and are then assembled together.
