Description

Technical Field

[0001] The present invention relates to a hexagonal wrench structure. In particular, it relates to a hexagonal wrench structure in which a first fitting portion, a second fitting portion, a third fitting portion, a fourth fitting portion, a fifth fitting portion, and a sixth fitting portion are integrally formed to simplify the overall body and reduce the cost of the body.

Background Art

[0002] In the prior art hexagonal wrench structure, for example, there is the "Improved Structure of Hexagonal Wrench" in Patent Document 1.

[0003] The "Improved Structure of Hexagonal Wrench" in Patent Document 1 includes a seat portion with a prism mechanism installed at the front opening end, a handle installed at the rear end of the seat portion and forming an appropriate bending angle with the seat portion, a first prism connected and fixed to the axial center part inside the seat portion, and at least one second prism fitted outside the first prism. It includes a prism mechanism in which the bottom end of the second prism and the first prism are fitted to each other by a concave-convex structure, and a spring with one end locked inside the seat portion and the other end locked to the bottom end of the second prism, and the second prism moves telescopically outside the first prism.

[0004] However, the hexagonal wrench structure in Patent Document 1 had the following drawbacks (1) to (4). (1) Inside the prism structure, a first prism and a second prism are provided. Due to the elastic force of the spring, with the third prism as the axis, the first prism is pulled into the second prism or protrudes from the second prism, or the second prism is pulled into the third prism or protrudes from the third prism. Friction occurs when the first prism and the second prism, or the second prism and the third prism are displaced relative to each other, which may cause wear of the first prism, the second prism, or the third prism. (2) In the hexagonal wrench structure, if the spring or the elastic expansion and contraction of the spring is not smooth during the operation process, the displacement of the first or second prism will not be smooth. In this case, while it is unlikely that a major problem will occur when the first, second, or third prism of a relatively large size is displaced, there is a risk that the displacement of the first, second, or third prism will not be smooth when it is displaced in a relatively small size. (3) The design of the first, second, or third prism was complex, which could increase manufacturing costs. (4) Displacement occurred between the first prism and the second prism, or between the second prism and the third prism, resulting in tolerances between the first prism and the second prism, or between the second prism and the third prism, which sometimes caused the first and second prisms to wobble slightly during rotation.
