AI Technical Summary
Existing electronic scales are easily modified and cheated by unscrupulous merchants, resulting in inaccurate weighing and harming consumers' interests.
The protective shell is designed with a conductive sheet system. When the protective shell is assembled, the conductive sheets adhere to each other to enable power supply. When the protective shell is opened, the conductive sheets separate and break the circuit, causing the circuit board to lose power, thus preventing modification and cheating. Adjustable support legs ensure the stability of the scale.
Effectively prevents electronic scales from being modified and cheated, ensures weighing accuracy, protects consumer interests, and maintains the stability of the scale.
