Tactile feedback mechanism and interaction device

The invention belongs to the technical field of force feedback, and particularly relates to a tactile feedback mechanism and interaction equipment. A protruding part is arranged on one side of a trigger, the section of the plane where the protruding part rotates along the trigger is an arc, the radius of the arc is R, the length from the circle center of the arc to the axis of a rotating shaft is L, R/L is smaller than or equal to 2/3, a driving assembly comprises a driving piece and a fixing shell, the fixing shell is connected with a fixing support, and the driving piece can do linear motion relative to the fixing shell. The side, close to the protruding part, of the driving piece is provided with a plane contact part, and the protruding part can be matched with the plane contact part in an abutting mode. According to the tactile feedback mechanism, the longitudinal displacement (namely displacement in the direction different from the moving direction of the driving piece) of the contact position of the tri
