The invention provides a fur stretching device, and relates to the technical field of fur processing. The fur stretching device comprises a shell, a placement plate, a limit plate, a support frame, slide blocks, a connection plate, a pressing plate, a rotary knob, a rotary disc, a pressing mechanism, a stretching mechanism, a fixed plate and a fixed knob, wherein the fixed plate is fixedly connected to the top end of the shell; the placement plate is fixedly connected to the top end of the fixed plate; the slide blocks are slidably connected to the left side and the right side of the placementplate; the connection plate is fixedly connected between the slide blocks; the pressing plate is arranged between parts below the connection plate, of the slide blocks; the rotary knob penetrates through the top end of the connection plate; the pressing mechanism is arranged at a part close to the middle part, of the top end of the placement plate; the support frame is arranged above the pressingmechanism; the bottom end of the support frame is fixedly connected with the shell; the limit plate is fixedly connected to one side of the placement plate; the rotary disc is arranged at the left side of the shell; and the stretching mechanism is arranged in the shell. According to the fur stretching device, the problem of a poor fur stretching effect due to excessive stretching and non-uniformstress on fur in a fur stretching process, is solved.
