The invention relates to a lifting electric cylinder capable of storing and releasing return energy, which comprises a motor, an energy recovery device, a transmission unit and a load connecting unit, the energy recovery device comprises a gear reducer and a torque storing and releasing device, and the transmission unit comprises a lead screw, a nut pair and a first outer spline shaft. The load connecting unit is connected with the nut pair and can reciprocate along with the nut pair, the first outer spline shaft is installed at the tail end of the lead screw, the torque storing and releasing device comprises a second outer spline shaft, the gear reducer at least comprises a first-stage gear shaft and a last-stage gear shaft, and the first-stage gear shaft is connected with the second-stage gear shaft. The first-stage gear shaft is in transmission connection with a motor shaft of the motor, the last-stage gear shaft is a hollow inner spline shaft, one side of the inner spline shaft is meshed with the first outer spline shaft, and the other side of the inner spline shaft is meshed with the second outer spline shaft. Energy can be recycled when the push rod returns, and the recycled energy is used for assisting the starting process of the electric cylinder.
