The rammer body includes a mounting block, the bottom end of the mounting block is provided with a ramming head, a vertical sliding groove is opened on the side surface of the mounting block, a slider is slidably connected in the sliding groove, and one end of the slider extending out of the sliding groove is fixedly connected with a horizontal splicing plate. When the slider slides to the bottom end of the sliding groove, the splicing plate and the ramming head are spliced into a whole; a fixing component is arranged on the splicing plate, and the splicing plate is fixed in the sliding groove through the fixing component; a strengthening component for strengthening the fixing strength of the splicing plate is arranged in the mounting block. It has the advantages that the contact area between the ramming head on the frog rammer and the ground can be adjusted according to the actual situation, so as to change the area of the land rammed by the ramming block falling once, and the applicability of the frog rammer is enhanced.
