The invention relates to a multifunctional corpuscle energy storage starter which comprises a spring, a spring sleeve, a spring bottom plate, an oil cylinder, a piston and an oil cylinder head. The spring sleeve is filled with the spring; the spring sleeve and the oil cylinder are fixed into a whole body; and the piston can push the spring bottom plate to move, so that the purpose of energy storage starting of stored oil is achieved. The multifunctional corpuscle energy storage starter avoids the measure of supplementing pressure through an oil pump during diamond production, saves electric power, ensures that produced diamond has high yield, large granule and high strength, and is particularly applicable to pressure maintaining during the diamond production process.
