The invention belongs to the field of underground construction mechanical equipment, and particularly relates to a grab bucket mechanism with an extension bucket and a continuous wall trenching machine with the grab bucket mechanism. The grab bucket mechanism comprises a guide bracket, a linear loading mechanism, two grab buckets and two push rods; the grab buckets are connected to the lower end of the guide bracket through a first rotating shaft; the linear loading mechanism is centrally mounted on the guide bracket relative to the two grab buckets; second notches are formed in the opening sides of the grab buckets, the opening sides of the two grab buckets are each connected with an expansion bucket through a second rotating shaft, the expansion buckets expand the grabbing range of the grab buckets on the outer sides of the second notches, and the opening and closing directions of the expansion buckets and the grab buckets where the expansion buckets are located are the same; the continuous wall trenching m
