A basket may include a main body and a side frame. The side frame surrounds at the portion of a connecting edge, and a first side and second side clamps with each other by applying a pressure on the side frame, so the first side clamps at an inner portion of the connecting edge and the second side clamps at an outer portion thereof. Thus, the side frame can be quickly connected with the main body without bending the connecting edge to a predetermined angle, which can simplify the assembly process and further reduce the production costs.
