| 摘要 |
A device including a first part and a second part which are inter-engageable with one another, the first part having a first longitudinal axis and a connecting face which extends substantially transversely to the first longitudinal axis and includes an engagement formation which extends substantially axially, and the second part having a second longitudinal axis and a connecting face which extends substantially transversely to the second longitudinal axis and includes a receiving formation which extends substantially axially and in which the engagement formation of the first part is receivable, wherein each of the engagement formation and the receiving formation includes a substantially helicoidal surface which extends at least partially around the longitudinal axis of the respective part of the connector, such that rotation of the two parts relative to one another about the longitudinal axes, when the two parts are substantially co-axially aligned, such that the connecting faces of the two parts face one another in a substantially axial direction, causes engagement of the engagement formation of the first part with the corresponding receiving formation of the second part. |
