Description
Technical Field
[0001] The utility model relates to the technical field of laser instruments, in particular to a direct-charging focus-adjustable laser lamp. Background Art
[0002] Laser light products currently on the market usually use replaceable batteries as a power source for endurance. When the internal battery is low on power, it is necessary to open the openable battery compartment component, which is usually a battery back cover or battery compartment designed to be screwed together. Long-term use and high-frequency opening and closing of the battery compartment component will cause damage to the connection between the battery compartment component and the product body. In addition, users who cannot distinguish between the positive and negative poles are prone to reverse the positive and negative poles of the battery, causing the laser light to not work properly. On the other hand, existing laser light products are usually designed with a fixed focal length. If the laser light is projected to a distance that is too short or too far, the projected pattern or light spot will be unclear, affecting normal use. In addition, the optical lenses of existing laser light products are usually fixed, and the pattern or effect of the laser display is single. Different display patterns or effects cannot be replaced or adjusted, and cannot meet the diverse needs of different consumers. Utility Model Content
