Abstract:
To provide a metal-made opening/closing-type hook tool.SOLUTION: In a metal-made hook tool 1 including a hook curved part 2 and a hook opening/closing bar 3, the hook opening/closing bar is rotatable with a rotating shaft 14 arranged at an upper apex part 18 of the hook curved part as a rotation center. When the hook opening/closing bar is locked to a shoulder part 4 while withstanding energization means, a band-shaped protrusion provided in a center of a shoulder surface and a band-shaped groove provided in a center part in a vertical direction of a surface of the hook opening/closing bar are engaged with each other, and then, the hook tool is brought into a release state by being locked by lock protrusions 15 at both sides provided at a lower end part of the band-shaped protrusion of the shoulder part and lock recesses 21 at both sides provided at the band-shaped groove of the hook opening/closing bar. When the hook opening/closing bar is energized by the energization means, the hook tool is brought into a closed state by a lock of a lower-end end part of the hook opening/closing bar and an opening end part, and the two lock protrusions at both sides of the band-shaped protrusion are provided at asymmetric positions.SELECTED DRAWING: Figure 1
