1. A force feedback device, comprising:
a base;
a trigger assembly comprising a trigger body, a connecting portion extending from the trigger body, a trigger formed by extending from a circumferential side of the trigger body in a direction away from the base, and an arc portion connected to the trigger body, wherein the connecting portion is supported on the base through a first transmission shaft to form a rotational connection, and the arc portion is spaced apart and opposite to the connecting portion and extends toward the base; the connecting portion is extended from an end of the trigger body; the end of the trigger body is closer to the base than a portion of the trigger body connected to the arc portion;
a driving assembly comprising a driving unit fixed to the base and a second transmission shaft connected to the driving unit, wherein the second transmission shaft is arranged opposite to the arc portion; the second transmission shaft comprises a transmission shaft body connected to the driving unit and a spiral groove formed on the transmission shaft body and extending along an axial direction of the transmission shaft body; and
a transmission medium arranged, in a surrounding manner, in the spiral groove of the second transmission shaft, wherein after the transmission medium is arranged to surround the second transmission shaft respectively, two drawn-out ends of the transmission medium extend in opposite directions along a circumferential direction of the arc portion and are fixed to two ends of the arc portion, such that part of the transmission medium abuts against the arc portion.
