The upper cover is threaded through a screw B that is connected to the housing, and the lower cover is threaded through a screw A that is connected to the housing. Screws A and B are used to fix the upper cover, the housing, and the lower cover. A battery is installed inside the housing. The battery is connected to a PCB board installed inside the housing. A weighing mechanism installed inside the housing is provided on the PCB board.

[0006] Preferably, the weighing mechanism includes: a weighing sensor mounted on a PCB board, the weighing sensor passing through a set screw threaded to a housing, the set screw being used to fix the weighing sensor inside the housing; a limiting sleeve fitted onto the weighing sensor, the limiting sleeve having a hook fitted onto it, the hook having a damping washer; a screw C passing through the hook and the limiting sleeve and threaded to the weighing sensor, used to connect the hook, the limiting sleeve, and the weighing sensor into a whole; a display screen mounted on the PCB board for displaying weighing signals, a switch mounted on the PCB board on one side of the display screen for controlling the power supply to and from the PCB board.

[0007] Preferably, a Type-C interface is connected to the PCB board, and the Type-C interface passes through the lower end cover.

[0008] The electronic scale with a portable power supply provided by this utility model has a slender shell with good pressure resistance and wear resistance. A sturdy metal hook is set on the top of the shell for easy weighing. It has a built-in high-precision weighing sensor, which is sufficient to meet the weighing needs of various daily items. An LCD screen and a power switch are embedded in the shell. When weighing an object, the weight is transmitted to the weighing sensor, which transmits the signal to the circuit board. The circuit board calculates the weight signal and displays it on the LCD screen, making it highly practical. Attached Figure Description
