A reel clamping device which is capable of positioning a reel rapidly and precisely. The reel clamping device is composed of a cylindrical shell having a plurality of through slots extended parallelly with the axis thereof; a screw bolt rotatably disposed within the shell, whose first and second threaded end portions have different thread directions; a jaw base mated to the first threaded end portion of the screw bolt; a plurality of first jaws fixed onto the jaw base and protruding from the through slots formed in the shell; a plurality of second jaws; a jaw seat mated to the second threaded end portion of the screw bolt, for accommodating the second jaws in such a way that the second jaws can protrude from or retract into the through slots freely; a second jaw drive mechanism mated to the second threaded end portion of the screw bolt, for driving the second jaws to protrude from or to retract into the through slots; and a handle for driving the screw bolt to rotate around its longitudinal axis so as to conduct the base and the seat to move toward or apart from each other and simultaneously to conduct the second jaws to protrude from or to retract into the through slots. The second jaw drive mechanism can conduct the second jaws to protrude from or to retract into the through slots within one turn of rotation about the axis of the shell, and the second jaw drive means is mated to the second threaded end portion of the screw bolt in such a way that it can be conducted to rotate integrally with the screw bolt by an adjustable frictional torque existed therebetween.
