Other foldable three-plugs are often difficult to insert or unplug in narrow spaces. The hot-melt connections between the pins are not stable enough and are prone to breakage after long-term use, affecting service life and even endangering health. When not in use, the protruding pins are prone to scratches or damage surrounding items. In addition, when carrying this type of plug, the unprotected metal pins are prone to accidental electric shock risks, and the safety and reliability of the electrical connection cannot be ensured, which also affects the overall aesthetics and durability of the product.
