The invention relates to the technical field of stirring rods, in particular to a handheld stirring rod and a processing method thereof. The handheld stirring rod comprises a housing, a stirring rod body, a microprocessor, a force sensor, a gyro sensor, a revolving speed sensor, a temperature sensor and a motor, and is characterized in that a plurality of signal ends of the microprocessor are respectively connected with the input end of a rectification circuit, the signal output end of the force sensor, the signal output end of the gyro sensor, the signal output end of the revolving speed sensor, the signal output end of the temperature sensor, the signal input ends of a plurality of LED lamps and one end of a power cord; the output end of the rectification circuit is connected with the input end of the motor; and the LED lamps comprise N speed display lamps, one work indicator light and one overload display lamp, where the N is a natural number larger than or equal to 3. Compared with the prior art, the speed is started and adjusted through the intensity of grip strength of fingers, and the operation is simpler. Moreover, the stirring rod, which has the functions of both overturn protection and overhead protection, is safer and more reliable for use.
