Abstract
A heart-shaped self-locking button includes one housing and one push rod. The push rod is slidably arranged within the housing. A heart-shaped structure is formed on the push rod. The button includes one pin and one flexible element. One end of the pin is fixed on the housing, while the other end is fitted with the heart-shaped structure. The flexible element is arranged between the housing and the push rod and presses the pin towards the heart-shaped structure to allow the pin to be in constant contact with the heart-shaped structure. The heart-shaped structure is arranged on the push rod. Also, the flexible element between the housing and the push rod is utilized to press the pin towards the heart-shaped structure on the push rod to allow the pin to be in constant contact with the heart-shaped structure when moving.
