1. A chip-fixing device for a socket, arranged on the socket, the socket including a chip slot for accommodating a chip to be tested, the chip-fixing device comprising:
a fixing base body, including a through opening and a socket-accommodating recess, the socket being assembled in the socket-accommodating recess, the chip slot of the socket corresponding to the through opening and being exposed from an upper surface of the fixing base body;
at least one movable stop, each movable stop including a stopper, the at least one movable stop being assembled in the fixing base body and controlled in such a manner that the stopper is moved between a first position and a second position,
at least one rocker arm, at least one first connection rod, and at least one second connection rod; the fixing base body including at least one arm-accommodating recess, at least one first elongated hole, and at least one second elongated hole, wherein the at least one rocker arm is accommodated in the at least one arm-accommodating recess; the at least one first connection rod extends through the at least one first elongated hole and is pivotally connected to one end of the at least one rocker arm and the at least one movable stop; the at least one second connection rod extends through the at least one second elongated hole and is pivotally connected to the at least one movable stop;
wherein the first position refers to a position where the stopper is located right above the chip slot of the socket during a non-testing period, and the second position refers to a position where the stopper is not located right above the chip slot of the socket during a testing period;
wherein when the stopper is located at the first position, a distance between the stopper and an upper surface of the chip to be tested is smaller than a depth of the chip slot of the socket.
