A plug unlocking structure of an optical transceiver module includes a main body, a linkage assembly, and a pull handle. The linkage assembly is pivotally coupled to the main body. The linkage assembly includes a locking arm and at least one linking arm extended from the locking arm. The extending directions of the locking arm and the linking arm are different, and an elastic element is installed between the linking arm and the main body. The pull handle is linked to the linking arm. The linkage assembly is pivotally coupled to the main body through the pivoting point of the locking arm, and the locking arm has a latching pin. The position of the pivoting point of the locking arm is between the latching pin and the linking arm.
