BACKGROUND OF THE INVENTION

The existing impact type digging impact mechanisms as punching and cutting digging equipment, impact heading equipment, bucket excavating equipment and the like is generally a double-layer impact mechanism or a multilayer impact mechanism. For the structural form of the double-layer or multilayer impact mechanism on the digging equipment, the structural forms of an inner-layer impact mechanism and an outer-layer impact mechanism are generally uniform structures or similar structures.
