Fixing tool for holding a midsole and a shoetree

Abstract

A fixing tool for temporarily holding a midsole and a shoetree in shoe industry includes a screw base and a screw body. The screw base is formed as a hollow hob screw with both an inner thread and an outer thread. The screw body further includes a screw holder and a screw. The screw has a flat round top portion with periphery notches and is pivoted at a center thereof to allow the top portion able to make a 90° rotation. The screw base is used to be screwed into a proper position at the bottom of the shoetree. The screw of the screw body is then engaged with the respective screw base through the midsole for temporarily fixing the midsole and the shoetree. The screw holder of the screw body can be pushed aside to contact with the midsole. Unlike the conventional nail-fixing, the fixing tool of the present invention can hold the midsole and the shoetree by only screwing the screw of the screw body into the screw base. By providing the fixing tool of the present invention, the screw body can be re-used, the damage upon the shoetree can be avoided, the labor can be saved and the cost for manufacturing the shoe can be reduced.
