Claims

[Scope of Claim for Utility Model Registration] A switching frame connected to a crane wire is connected to a main body frame in a vertical position in which the lower side is in contact with an object to be lifted such as a shaped steel so as to be able to slide up and down, and the switching frame is attached to the left and right sides of the switching frame. The hook members are provided with their hook parts facing each other via a parallel link mechanism, and the middle part of one of the link rods constituting the parallel link mechanism is connected to both lower side parts of the main body frame by a rod. On the other hand, a shaft having a switching member having a cross-shaped front shape and a single-letter-shaped operating rod parallel to one side of the switching member is coaxially attached to the lower part of the switching frame, and the switching member is connected to the shaft. The member is positioned so as to be able to approach and separate from a switching rod that is pivotally supported to rotate only in an upward direction with respect to the inner surface of the main body frame, and is engaged with both ends of the operating rod in a horizontal position,
A hanging tool such as a shaped steel, characterized in that the main body frame is provided with a stopper member through which a working rod in a vertical position passes.
