FIELD: electricity.SUBSTANCE: invention is referred to a flashlight equipped with a case, light source and flashlight head having lens attachment, which may be shifted axially in longitudinal direction in regard to light source in order to ensure focusing of the emitted light cone. The flashlight is equipped with a case (16), light source and flashlight head (14) having lens attachment (20), which may be shifted axially in longitudinal direction in regard to light source in order to ensure focusing of the emitted light cone and a locking device (1) in order to fix flashlight head (14) in free longitudinal axial direction, at that the locking device (1) has locking case (2) capable to turn around longitudinal axis of the flashlight (3), at that at the end there is at least one radially oriented and turnable or expandable clamping element (11, 11'); the locking device is a cylindrical connecting element (41), coupled positively to the flashlight head (14) and placed on the flashlight case (16) so that its motion is ensured by pressing on it; the locking device represents a cylindrical connecting element (51) connected the flashlight head (14) by means of threaded connection (52); the locking device is made as several mounting elements (61) entering slots (62) of a locking element (63).EFFECT: development of the flashlight ensuring, on the one hand, smooth shifting of the reflector in regard to light source and, on the other hand, preventing unintentional shifting of the preset focus.21 cl, 15 dwg, 4 ex |
