Abstract

A tamper-proof screw includes a main body, a pin body, a ball, and at least one abutting member. A through hole is provided in the main body. The pin body is movably disposed in the through hole. The ball is located in the through hole. The abutting member is located in the through hole and has a connecting end and a free end opposite to each other. The connecting end is disposed on an inner wall of the main body and located between the ball and the free end. The ball is located between the pin body and the abutting member. When the pin body moves in the through hole to push the ball to press against the connecting end of the abutting member, the abutting member pivots around the connecting end to allow the free end to extend outwards from the main body.
