A manual cup sealer includes a frame unit, a sliding carrier board slidably mounted in the frame unit and carrying a lower electric heat sealing die, a transmission shaft pivotally mounted in the frame unit, a first link coupled to the transmission shaft, a first spring member connected between the first link and the sliding carrier board, a die link connected to the transmission shaft through a second link and holding an upper electric heat sealing die, and a handlebar operable by a user to rotate the transmission shaft clockwise/counter-clockwise for causing the sliding carrier board to be moved in and out of the frame unit and the upper electric heat sealing die to be lowered toward the lower electric heat sealing die to seal a sealing film to a plastic cup in the lower electric heat sealing die.
