Then connect the plug rod type flower drum body 102 to the cylindrical rod 101 through the receiving groove 103. Then, press the buckle 205. When the limiting cylinder 201 moves to the position of the buckle 205, the limiting column 204 transmits the force to the spring 203. At this time, the spring 203 is compressed. When the clamping hole 206 on the limiting cylinder 201 moves to the position of the buckle 205, the spring 203 restores the buckle 205 into the clamping hole 206, realizing the installation of the plug rod type flower drum body 102. Then, screw the limiting screw 304 into the first threaded groove 301, the second threaded groove 302, and the third threaded groove 303 in turn. Connect the components to the grinder through the mounting rod 308. Then, turn on the grinder to drive the plug rod type flower drum body 102 to grind in the grinding medium. When it is necessary to disassemble the ground plug rod type flower drum body 102, first remove the limiting screw 304, then press the buckle 205, at this time the spring 203 is compressed, when the buckle 205 is separated from the clamping hole 206, the limiting cylinder 201 is moved downward, then the plug rod type flower drum body 102 is removed. This step reduces the operation time compared to bolt connection disassembly, and can avoid the buckle 205 shaking and causing the plug rod type flower drum body 102 to loosen during grinding. At the same time, it can realize the grinding of plug rod type flower drum bodies 102 of different sizes.
