The invention relates to a walking beam fulcrum spring plate storage and release kinetic energy power assisted brake start pumping unit which comprises a spring plate which is arranged between a pumping unit support and a walking beam fulcrum, at the side of a horsehead and along the same direction of a walking beam. The free end of the spring plate is provided with a spring roller wheel and a spring bearer plate is arranged below the walking beam and corresponds to the spring roller wheel. Compared with the prior art, the walking beam fulcrum spring plate storage and release kinetic energy power assisted brake start pumping unit has the advantages of being more balanced and more stable in operation, saving energy consumption and being good in popularization and utilization value, due to the fact that the natural gravity of descending of a pumping rod and the inertia power of moderation are stored on the spring plate to form potential energy on the declivitous tail end of the walking beam, the spring plate re
