ABSTRACT:
A tamper-evident mechanism for use with an electronic appliance includes a first housing, a second housing, a fastening device and a shielding element. The first housing includes a perforation, which is surrounded by a ring-shape member. The second housing includes a groove corresponding to the perforation of the first housing, wherein the groove has an inner thread formed on a portion of inner wall thereof. The fastening device includes a head portion and a shaft portion, wherein the shaft portion has an external thread engaged with the inner thread of the groove and the head portion is sustained against the ring-shape member, thereby coupling the first housing with the second housing. The shielding element is inserted into the perforation of the first housing for shielding the head portion of the fastening device.
