New description: [New technical field] This case belongs to the field of lighting equipment, especially for a lighting fixture with a flexible circuit board between the power source and the slippable inner bracket. Zoom structure. [Prior Art] Press 'Generally the most portable light fixtures for portable lighting or emergency lighting are flashlights. Most flashlights in the past have only a single brightness or limited illumination range, which greatly reduces the convenience of use. Therefore, flashlights that increase the brightness of the illumination or change the illumination range are successively appearing on the market, and the light-emitting diode (LED) is used as the illumination source, and the LED illumination source has small volume and low power consumption. The advantages of high brightness and long life can greatly reduce the size and weight of the flashlight.
