The column 82 is adapted to the first groove 5, and the ring body 83 is adapted to the incremental block 4. The inner side of the ring body 83 is fixedly connected with a slope block 86. The ring body 83 and the incremental block 4 are fixedly connected by bolts 87. By inserting the column 82 into the first groove 5 and utilizing the slope block 86 to insert the insertion rod 81 into the socket 85, the column 82 and the incremental block 4 are fixed, thereby indirectly achieving internal fixation between the incremental block 4 and the hammer core 3, and utilizing the ring body 83 and the bolt 87 to achieve external fixation between the incremental block 4 and the hammer core 3, thereby improving the overall fixing effect.

[0025] The incremental block 4 is composed of an upper hammer block 41 and a lower hammer block 42, and the upper hammer block 41 and the lower hammer block 42 are detachably connected. There are multiple upper hammer blocks 41 arranged in the vertical direction, and the multiple upper hammer blocks 41 are detachably connected to each other.

[0026] The reset mechanism 84 includes a spring 841 and a baffle 842 . The spring 841 in the figure is in a compressed state. The spring 841 is sleeved on the outer surface of the insertion rod 81 , and the baffle 842 is fixedly connected to one end of the insertion rod 81 .

[0027] One end of the spring 841 is fixedly connected to one side of the baffle 842 , and the other end of the spring 841 is fixedly connected to the groove wall of the second groove 6 .
