Abstract: Provided is a modular actuator joining device. A housing forms an external appearance of a modular actuator. Coupling pieces are formed along opposite end edges of outer surfaces of the housing. Accordingly, the coupling pieces formed with first to third fastening parts. Nuts are installed inside fastening holes that form the fastening parts such that fasteners are fastened to the fastening parts. Modular actuators may be variously joined to each other. In addition, any other component may be variously joined to the modular actuator. Further, two or more modular actuators may be joined to each other without using a connecting member.

Abstract: The present invention relates to a fastener and a disassembling apparatus for the same. The fastener (10) of the present invention has a cylindrical hollow body (12) which configures a framework. A through hole (14) is penetrated through an inside of the hollow body (12) in a longitudinal direction thereof. A plurality of coupling legs (16) are formed by deformation slits (18) to extend toward one end portion of the hollow body (12). A coupling protrusion (20) is formed at an outer surface of the front end of the coupling leg (16), while a releasing portion (24) is formed at an inner side of the hollow body (12) which is opposite to the outer surface. A placing step (22) is formed in a stepwise manner at a location adjacent to the other end portion of the hollow body (12) which corresponds to an opposite side of the coupling protrusion (20). A separating protrusion (28) is formed at an end of the other end portion of the hollow body (12).
