FIXING METAL FITTING TOOL FOR HANGING BOIL
Document Type and Number:
Japanese Patent JP3023535
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a fixing metal fitting tool for a hanging bolt having an inexpensive general-purpose structure without decrease of the fixing work efficiency.
SOLUTION: A bottom plate 111 is provided with a screw hole screwed in by a handing bolt. A narrowed part 122 and a claw 123 are formed in a fitting blade 121. The narrowed part 122 ristricts the relative rotation against the hanging bolt, since both blades thereof are made narrower than the diameter of hanging bolt. But when the hanging bolt is screwed by a relatively large rotary force, the distance between both blades is widened to allow the hanging bolt to do the relative rotation. The claw 123 is formed by twisting and bending and the form is shaped to widen the distance between both blades and continuously widened to the direction by screwing the hanging bolt.
