Illuminating lamp capable of rotatably adjusting light distance

Abstract

The utility model relates to an illuminating lamp capable of rotatably adjusting the light distance. The problems that in the prior art, an illumination lamp is complex in structure and small in light distance adjusting range are solved. The device comprises a lens seat, one end of the lens seat is connected with a lamp holder, one end of the lamp holder far away from the lens seat is provided with a battery loading shell, a lens sliding adjusting mechanism is arranged in the lens seat, and a rotation driving mechanism is arranged between the battery loading shell and the lamp holder. A lighting lamp set structure which is connected with the rotation driving mechanism and is driven by the rotation driving mechanism to move is arranged in the lamp holder, and a stroke limiting assembly used for limiting movement of the lighting lamp set structure is arranged in the lamp holder. The optical distance adjusting device has the advantages of being simple in structure, large in optical distance adjusting range, good in using effect and capable of meeting diversified optical distance adjusting requirements.
