Abstract: The present invention relates to a locking mechanism for a press head, and an electronic device testing apparatus comprising the same, wherein a slider and a locking pin are disposed on the press head and a test socket substrate, respectively. When the press head is moved and engaged with the test socket substrate, an actuator drives the slider to secure the locking pin, so as to secure the press head and the test socket substrate and prevent the press head and the test socket substrate from being separated from each other. The mechanism is simple in construction, easy to install and maintain, reliable, and can be integrated into the support arms, and occupies a relatively small space. Energy is consumed only when the actuator is actuated to effect locking or unlocking. That is, only when the slider is driven and moved, energy is consumed. No extra energy is needed to persistently press down or drive the locking mechanism.
