Abstract

An ice shaving machine includes a drive unit, a limit plate secured on the drive unit, and a shaving frame detachably combined with the limit plate. The drive unit includes a rotation disk. The limit plate has a through hole and a plurality of locking grooves. The shaving frame has a receiving chamber and a shaving blade. The shaving frame has a connecting lug detachably locked onto the limit plate. The connecting lug has a passage connected to the receiving chamber and has a plurality of locking pieces that are detachably locked in the locking grooves of the limit plate. Thus, the shaving frame can be rotated to remove from the limit plate so that the shaving frame is detached and cleaned easily and conveniently.
