Prefabricated wallboard positioning hole tool for concrete prefabricated part

The utility model belongs to the field of building products. The utility model relates to a tool, in particular to a prefabricated wallboard positioning hole tool of a concrete prefabricated part. Anexisting base and an existing transverse supporting arm are fixedly installed on a leaf wall mold. Bolts are mostly adopted for fixed installation; bolt installation complexity, easily rusted, the problem of thread slipping easily occurs in the mounting process; proposed now is the following scheme, the mold comprises a leaf wall mold, a base is arranged on the leaf wall mold; a transverse supporting arm is arranged on the base; mounting block is arranged on base, a mounting groove is formed in the leaf wall mold; one side of the mounting block extends into the mounting groove; the bolt is simple in structure, the pressing rod moves to drive the V-shaped rod to rotate, the V-shaped rod rotates to drive the pushing rod to move, the pushing rod moves to drive the fixing block to extend intothe fixing groove, the mou
