Female threaded parts handling tool

Abstract

In the reference diagram (a) of the state of use, the left end is the female threaded member, the center is the formwork, and the right end is the female threaded member handling tool. In the reference diagram (b) of the state of use, the narrow angle of the bending and extending part of the hinge part of the article of the present design is narrowed, and the partial male threads on both the upper and lower sides of the left side become parallel by pushing in the T-shaped knob, and an imaginary male thread part appears, and this imaginary male thread part is inserted into the mounting hole of the formwork and screwed and fastened relatively to the female thread of the female threaded member, and the female threaded member is set in the formwork. The formwork is filled with concrete, and when it hardens, the T-shaped knob is unscrewed to pull out the female threaded member and the formwork. When the formwork is removed, the female threaded member is embedded and a concrete product with the female thread part open is obtained. In the reference diagram (c) of the state of use, a jig with a different thread diameter is interposed between the female threaded member handling tool inserted into the through hole of the formwork at the right end and the female threaded member at the left end.
