The pivot portions have teeth (314), (324) on circumferential peripheries thereof. The teeth mesh with each other. The cover can rotate for 360 degrees relative to the main body thereby moving from a first position to a second position, wherein at the first position, the cover abuts against a top surface (326) of the main body, and at the second position, the cover abuts against a bottom surface of the main body. The trajectory of the cover during its rotation relative to the main body follows a predetermined path.
