Abstract

The invention discloses a telescopic electric torch with the conveniently-adjusted luminance. The telescopic electric torch comprises a torch body (1). A connecting base (2) is arranged at the lower end of the torch body (1). Focusing threads (3) are arranged on the connecting base (2). A plurality of transparent sheets (4) are connected to the outer edge of the lower end of the connecting base (2), and the transparency of the transparent sheets (4) is different. Fixing threads (5) are arranged at the lower end of the corresponding transparent sheet (4). A lamp bead (6) is arranged in the transparent sheets (4). A lampshade (7) is connected to the outer side of the connecting base (2). Inner threads are arranged at the top end of the inner side of the lampshade (7). A lens (8) is connected to the middle of the lower end of the lampshade (7). A light reflection cover (9) is connected to the upper portion of the lens (8). A light reflection sheet (10) is arranged on the light reflection cover (9). Through holes (11) are formed in the middle of the light reflection sheet (10) and the middle of the light reflection cover (9). The telescopic electric torch has the advantages of being large in illuminating range and wide in application range, the luminance can be conveniently adjusted, and use is convenient.

Description

technical field [0001] The invention relates to a retractable flashlight, in particular to a retractable flashlight which is convenient for adjusting brightness. Background technique [0002] The flashlight is a portable hand-held lighting tool with concentrated light and long range, but the range of illumination is small. When there is a power failure or there is no electric light outside, the flashlight cannot meet people's needs for the lighting range, and the scope of application is small; moreover, the brightness of the existing flashlight is generally fixed. The problem of inconvenient brightness adjustment. Therefore, the existing flashlight has the problems of small lighting range, small application range and inconvenient brightness adjustment. Contents of the invention [0003] The purpose of the present invention is to provide a retractable flashlight which is convenient for adjusting brightness. The invention not only has the advantages of large lighting rang...
