The utility model uses a pressing rod structure to press the button area below for testing, and a cam is fixedly installed coaxially through the rotating shaft. The cam is divided into a large diameter wheel and a small diameter wheel to realize the circulation of different diameters, realize the periodic reciprocating pressure on the upper support block below, and can perform a fast periodic button pressing action. The upper support block is automatically pulled upward by a reset spring to ensure that the support block is in close contact with the outer side of the cam, so as to better test the strength and durability of the button.
