Abstract: A tool hanging rack includes a rack member that is made of an aluminum based material and can be attached to wall through magnetic attraction, fastening, hanging, and suction cups, a plurality of tool holders slidably fit to the rack member, two end retention seats respectively fit to opposite ends of the rack member, and magnets mounted to a back side of the rack member. The rack member has a side forming a curvedly convex surface and slide rails and also forms channels for receiving the magnets. The end retention seats each form a support brace to provide additional support to the rack. The tool holder having a side forming a fitting section to fit to the surface and side rails of the rack member and an opposite side forming a diagonally-arranged, double-side-open, dual-layered symmetric retention receptacle slot, which is selectively set leftward-facing or rightward-facing.

Abstract: A cap structure for a radiator used in vehicle is disclosed. The cap includes a main cap body, a connector shaft, and a leak-seal seat. The main cap body includes a metallic cap body and a heat-isolation covering body joined together using screw as a body. The connector shaft is screwed onto the leak-seal seat, and the connector shaft passes through the through hole of a metallic sleeve mounted on the heat-isolation covering body. The side of the protruded rim of the connector shaft urges the end face of the sleeve and a spring is used to mount the connector shaft onto the main cap body. The heat-isolation covering body with a thickness is mounted onto the metallic cap body and two screws are used to lock the metallic cap body onto the heat-isolation covering body to form a unit, and the end side of the covering body is provided with slip-proof teeth and the metallic sleeve is mounted onto the center circular hole.
