Testing device for an electronic device having two pivot points

A testing device, suitable for testing an electronic device, wherein the electronic device has a first body and a second body, and the first body is suitable for rotating relative to the second body, the testing device comprising:

• a carrying platform, for carrying the first body;
• a fixed frame, pivoted to the carrying platform;
• a clamping element, pivoted to the fixed frame, for clamping the second body;
• a first driving element, disposed between the carrying platform and the fixed frame, for driving the fixed frame to pivot relative to the carrying platform;
• a second driving element, disposed between the clamping element and the fixed frame, for driving the clamping element to pivot relative to the fixed frame;
• a first shaft sensor, disposed between the carrying platform and the fixed frame, for sensing a first pivot angle of the fixed frame relative to the carrying platform;
• a second shaft sensor, disposed between the clamping element and the fixed frame, for sensing a second pivot angle of the clamping element relative to the fixed frame;
• and
• a control unit, coupled to the first driving element, the second driving element, the first shaft sensor, and the second shaft sensor, for controlling the first driving element and the second driving element according to the first pivot angle and the second pivot angle.
