An agentia distributor comprises a basic shell, a dividing wheel rotatable in the basic shell and a circuit device, wherein multiple grooves arranged at intervals of equal angles are formed in the dividing wheel and are used for accommodating corresponding agentia bags on an agentia belt, the dividing wheel is provided with an end face, and the circuit device is arranged in the basic shell and comprises a first circuit board, multiple magnets and a Hall sensor. When the dividing wheel is located at the position where the Hall sensor is not aligned to any one of the magnets, the Hall sensor isin a first sensing state which no magnet is not sensed; when the dividing wheel rotates to the position making the Hall sensor not to be aligned to any one of the magnets, the Hall sensor is in a second sensing state which a magnet is sensed; when the first sensing state is switched to the second sensing state or the second sensing state is switched to the first sensing state, the Hall sensor produces signals.
