A lamp-mounting unit is disposed in the main sleeve, and is rotatable about two aligned second pivot shafts formed on the pivot ring and extending inwardly and radially toward each other and perpendicular to the first pivot shafts. A lamp unit is mounted fixedly on the lamp-mounting seat such that an assembly of the lamp-mounting seat and the lamp unit is pivotable relative to the pivot ring about the second pivot shafts.
