Abstract

A hand-held toothpaste squeezer is disclosed. The squeezer comprises: a housing; a squeezing mechanism provided in the housing, the squeezing mechanism comprising a drive shaft and a driven shaft engaged with the drive shaft via gear at one end, the drive shaft being parallel to the driven shaft and having a gap in a range of 0.5-1 mm with respect to the driven shaft; the drive shaft being further provided with a stepping gear; the inlet of the housing, the gap between the drive shaft and the driven shaft, and the outlet of the housing being aligned with each other; an actuating mechanism comprising an elastic button and an actuating element. The plastic or metal toothpaste tube is squeezed from the bottom up, which prevents the air from entering and reduces the deposit of the toothpaste.
