a sleeve fixing tool of a mold

The present invention relates to a sleeve fixture for fixing to a concrete casting formwork when the sleeve is installed in a building, and in particular, if the sleeve is made by screwing a female fixture and a water fixture to a metal formwork without having to pre-drill holes in the formwork. The sleeve can be fixed so that workability for the sleeve construction is excellent. It is intended to be quick and easy. Recently, a technique has been proposed to fix the sleeve to the metal formwork by screwing the female fastener and the water fastener so that the sleeve can be embedded in concrete, but the disadvantage of this technique is the hole for fixing the female fastener to the formwork. Because it requires the work that needs to be drilled in advance, the inconvenience caused by this, as well as the additional time it takes. Therefore, in the present invention, the coupling groove is formed on the bottom surface of the nut groove of the female fastener to which the male fastener is coupled, and the screw is formed with a perforated blade on the outer end thereof so that the female fixture by the binding groove is formed on the metal formwork. It is easy to fix it, and it is easy to fix it exactly where you want to install the sleeve.
