The invention discloses a high lift range thin type compressing block. The compressing block comprises a left wedge block, a right wedge block, an upper wedge block and a lower wedge block; the wedge surfaces of the wedge blocks match with each other to form a wedge bond body; the end faces of the wedge-shaped small ends of the left wedge block and the right wedge block are equipped with alternate groove structures; when the left wedge block and the right wedge block move towards each other, the end face bosses formed by the left wedge block and the right wedge block are enabled to stretch in the groove structures of the opposite sides, thus forming fit; the limit distances of the left wedge block and the right wedge block in opposite movement are increased; the vertical lifting distances of the upper wedge block and the lower wedge block are improved; the thickness of the compressing block can be correspondingly thinned on the premise of keeping the original lifting distance of the compressing block; and therefore, the compressing block is mounted successfully.
