Description

TECHNICAL FIELD

[0001] The utility model belongs to portable lamps technical field, concretely relates to the clip lamp of universal rotation. BACKGROUND

[0002] In the field of lighting equipment, the universal rotating shelf lamp is widely used in office, study, reading and artistic creation and various scenes because it can flexibly adjust the lighting angle and direction, greatly improving the user's use convenience and comfort. The traditional universal rotating shelf lamp usually adopts a clip with a torsional spring or a metal elastic piece structure as a fixing device. Although this design realizes stable clamping of the lamp head on the horizontal plane to a certain extent, it also has obvious limitations. Specifically, the design principle of this kind of clip relies on the deformation of the torsional spring or the metal elastic piece to generate clamping force, thereby realizing the fixation of the desktop or other planar objects. However, this fixation method often has a relatively strict limit on the thickness of the object. When the thickness of the object to be clamped exceeds the preset clamping range of the clip, the clip often cannot provide enough clamping force, resulting in loosening of the lamp body, even falling, thereby failing to realize effective universal rotation and stable lighting. In addition, for uneven or complex surface structure desktops, the traditional clip may also fail to be stably installed due to the inability to closely fit, further limiting its use scenarios and convenience.
