The invention discloses a speed reducer with an overload protection function. The speed reducer comprises a base, lug blocks are fixed to the two ends of the base through bolts, a containing groove is formed in the top of the base, a first sliding groove is formed in the inner wall of the bottom of the containing groove, and two first sliding blocks are slidably connected into the first sliding groove; the same first spring is fixed between the two first sliding blocks through bolts, the tops of the first sliding blocks are rotationally connected with supporting plates through bearings, the tops of the two supporting plates are rotationally connected with the same speed reducer base through bearings, a pressing block is fixed to the bottom of the speed reducer base through bolts, and an emergency power-off switch is fixed to the inner wall of the bottom of the containing groove through bolts. When overload occurs, the torque borne by load connecting ends is increased, the speed reducer base moves downwards, t
