The invention provides a self-recovery memory alloy wire pin puller with variable driving force, which comprises a pin shaft, a shell with a hollow cavity, a movable pull disc, a memory alloy wire, a spring and a fixed pull disc, the pin shaft, the shell, the movable pull disc, the spring and the fixed pull disc are coaxially arranged, the fixed pull disc is fixed in the hollow cavity of the shell, and the memory alloy wire is arranged in the fixed pull disc. The movable pull disc is installed in a hollow cavity of the shell and is in sliding fit with the shell through a pin shaft, the movable pull disc is in axial sliding fit with the fixed pull disc, the pin shaft is fixedly connected with the movable pull disc, and the spring is clamped between the fixed pull disc and the movable pull disc. And the memory alloy wire is wound between the fixed pull disc and the movable pull disc. The device has the beneficial effects that the pin pulling force is improved, the wire diameter specification and the winding number of turns of the memory alloy wire are variable, automatic recovery can be achieved after use, and assembling is easy.
