Abstract: An overload protection assembly includes a first gear of a servo, a second gear of the servo, defining a receiving space; and a clutch configured to coaxially couple the first gear to the second gear and transmit torque between the first gear and the second gear. The clutch includes an elastic member arranged around the first gear and received in the receiving space. The elastic member includes a number of protrusions at a circumferential surface thereof, and a number of recesses are defined in a lateral surface of the receiving space. The protrusions are used to be respectively engaged with corresponding ones of the recesses so as to couple the firs gear to the second gear when a value of the torque is less than a preset value, and disengageable from the corresponding ones of the recesses so as to disconnect the first gear.
