The present invention discloses a coupling device for a shaft which includes a coupling disk (1), a disk (2), a force generating member (3), a first and second concave-convex assemblies (4,5), and a pull rod (14). The first and second concave-convex assemblies (4,5) are configured to be press engagement arrangement in which rotational angular displacement and axial displacement relative to each other is operable. The first concave-convex assembly (4) and said disk (2) are configured to be a press engagement arrangementin which rotational and sliding angular displacement between said first concave-convex assembly (4) and said disk (2) relative to each other is operable. An external force association member (6) is provided between the first concave-convex assembly (4) and an external force member (7). The external force association member (6) and the concave-convex assembly (4) are configured to be press engagement arrangement in which axial sliding displacement relative to each other is operable. The concave-convex assembly (5) is mounted on the coupling disk (1). One end of a spring (3) is associated with the disk (2), and the other end of the spring (3) is connected with the pull rod (14). The pull rod (14) passes through the disk (2) so as to be associated with the coupling disk (1). The coupling disk (1) is mounted on the out-extending shaft (8) or connected with the out-extending shaft (8) through a shaft coupling member (9). In this way, a coupling device for a shaft is formed in which the external force member (7) and the out-extending shaft (8) are associated. <IMAGE> |
