The invention discloses a crystal oscillator test device comprising the following parts: a pedestal; a support symmetrically arranged on the pedestal; a rotary shaft that penetrates the support and extends outside two sides of the support; a mount plate arranged on the rotary shaft; a disc fixed on the inner side of the support. The mount plate is used for bearing the crystal oscillator; the discis arranged between the support and the mount plate; the disc and the rotary shaft are concentrically arranged; the disc is provided with a plurality of adjusting holes axially symmetrically and evenly arranged around the center of the disc. The crystal oscillator test device can improve the test accuracy and test efficiency.
