[0002] A flashlight is a common lighting tool, generally used only by hand. However, in situations where handheld operation is inconvenient, existing flashlights cause operational difficulties for users, severely impacting the user experience. Examples include Chinese invention patents with application number CN202411352978.4 (publication number CN118998709A) and application number CN202411284200.4 (publication number CN118912461A).

[0003] Furthermore, early flashlights typically used dry cell batteries, while current flashlights generally use rechargeable batteries, usually charged by household power. However, when used outdoors, it's often difficult to obtain an external power source, causing the flashlight to lose its function due to the inability to charge, thus affecting its normal use. Hand-crank charging is a method of powering rechargeable batteries through a hand-cranking motion, which is not limited by the usage environment and easily solves the flashlight charging problem outdoors. However, existing hand-cranked flashlights often lack a structure to position the crank, so the crank can easily rotate when the hand-cranking function is not in use, posing a safety hazard. In addition, existing flashlights lack corresponding waterproof structures to prevent water from entering the battery compartment where the rechargeable batteries are installed. When used outdoors, the rechargeable batteries are easily damaged by water immersion, affecting the flashlight's lifespan. Summary of the Invention
