Abstract

This invention discloses a combined chopping board including a main chopping board and several additional chopping boards, the main chopping board and additional chopping boards are connected by means of a movable connection structure. The movable connection structure includes a hole stopper consisting of a head part and a neck part, this neck part is inserted in the through hole of the main chopping board across the through hole of the additional chopping board to fix the additional chopping board on the main chopping board; it can fulfill the need to use many chopping boards by the same user and can be selected according to the specific properties of the food, such as uncooked or cooked, the hardness of cutting through, and so on. The boards can be replaced and cleaned conveniently and the storage room can be saved with many chopping boards folding to an integral.
