By rotating the screw 103, the positioning member 104 moves inside the slide groove 102. By placing the sheet metal assembly on the main body 101, the positioning member 104 can push the sheet metal assembly. Then, the rectangular protrusion on the mounting member 201 contacts the positioning member 104, ensuring that the sheet metal assembly is in a straight position. The sheet metal assemblies are manually joined together, which can provide auxiliary positioning for the sheet metal assembly. By rotating the worm gear 302, the worm gear 302 meshes with the turbine on the rotating member 203, which in turn drives the rotating member 203 to rotate inside the mounting groove 202. The fixing rod 401 is slidably installed inside the rotating groove 204 through the cylindrical protrusion.
