The embodiment of the application can meet different requirements of different wireless network devices on a power supply end, thereby solving the problem of insufficient power supply and improving the power supply energy-saving effect.

The utility model discloses a structure of an electric shaver with an adjustable cutter head angle, which relates to the technical field of electric shavers. It includes a shaver main body, and a cutter head assembly is arranged above the shaver main body. An adjusting mechanism is arranged inside the shaver main body. The adjusting mechanism includes a fixed base and an adjusting top plate. An adjusting worm is rotatably connected to the bottom of the adjusting top plate. Arc-shaped support plates are fixedly connected to both ends of the adjusting top plate. A limiting worm wheel is fixedly connected to the middle of the fixed base. Through the settings of the fixed base, the adjusting top plate, the adjusting worm, and the limiting worm wheel, the rotation of the adjusting worm can drive the adjusting top plate to swing on the fixed base, and the swinging of the adjusting top plate drives the adjusting connecting rod to swing, thereby adjusting the cutter head angle of the device, enabling the device to meet the different requirements of the cutter head inclination angle when the user shaves the beards of different parts, and effectively improving the applicability and comfort of the device.
