Keychain

Abstract

【Item Uses】 The item designed here is a keychain with a tool head clamping structure. 【Design Description】 This design is for a keychain. Its main shape comprises a cylindrical body and a protruding section extending outwards from one end. The outer surface of the body has multiple elongated grooves and elliptical concave surfaces extending axially. The protruding section includes a protruding segment and a connecting segment. One end of the body slightly bulges outwards, forming an approximately hexagonal protruding segment, with the connecting segment protruding outwards from its center. The connecting segment is short and columnar, with a through-hole at one end for attaching a hanging ring or key ring. The other end of the body has a hexagonal groove for mounting tool heads or connectors. The shading lines shown in this design are for illustrating the three-dimensional shape and are not intended to represent surface patterns.
