The device comprises a flexible clamp comprising an elongated gap open to its rear, a lower receptacle, two recessed slides at both outer sides of the receptacle, and a toothed-section on a top of the receptacle; a sliding seat of U-section comprising two tabs at both inner sides for retaining a lower portion of the clamp in place after removably sliding the slides therethrough, a latch projected from its bottom to urge against the toothed-section, and a flexible hook having a toothed inner surface; and a lens hingedly coupled to the inner surface of the hook in a gear manner, and a universal joint type light mounted on top of the clamp. The invention enables a desired object to be seen larger and more clear through the pivotal lens (e.g., a magnifying lens) and with light emitted from the light.
