[0007] The grinding stone has a snap-fit ​​groove on the side near the mounting groove, the snap-fit ​​groove passes through the top and bottom of the grinding stone, the snap-fit ​​groove and the protruding block are engaged and connected, the protruding block has a connecting hole, the grinding stone has a mating hole corresponding to the connecting hole, and a fixing screw is connected between the connecting hole and the mating hole.

[0008] Preferably, multiple connecting holes are provided, and the multiple connecting holes are evenly distributed along the height direction of the protruding block, and one side of the protruding block does not extend out of the mounting groove.

[0009] Preferably, the honing rod body has an insertion hole on its outer side and a cavity inside the honing rod body. The insertion hole and the cavity are connected. An air hole is provided between two adjacent mounting slots. The air hole is located on the outer side of the honing head and is connected to the interior of the cavity.

[0010] Preferably, the grinding stone extends out of the mounting groove on the side away from the grinding head, and cutting edges are provided at the top and bottom of the extended end.

[0011] Preferably, the grinding head has scale lines along the height direction on its outer side.

[0012] Preferably, the air holes are provided in multiple locations, and the multiple air holes are distributed at equal intervals along the height direction of the grinding head.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. In the actual operation of this utility model, the grinding stone can be installed in the corresponding mounting groove by fixing screws, and one side of the grinding stone can protrude from the mounting groove. When the honing rod rotates, the workpiece hole can be polished by multiple rotating grinding stones. By setting the snap-fit ​​groove and protruding block, the connection between the grinding stone and the grinding head is more stable and the structural strength is improved.

[0015] 2. Furthermore, by twisting the rotating sleeve, the rotating sleeve rotates and descends on the grinding head, thereby blocking the upper half of the mounting groove, thus shortening the installation length of the mounting groove, so as to facilitate the installation of other shorter grinding stones. Since the rotating sleeve can block the upper half of the mounting groove after rotating and descending, it can prevent the debris generated during grinding from entering the inside of the mounting groove, and at the same time improve the installation stability of shorter grinding stones.

[0016] 3. In actual operation of this utility model, a pipe can be inserted into the socket, and a fan or air pump can be connected through the pipe. When the grinding head grinds the inside of the workpiece hole, the airflow can be discharged from the air hole to the inner wall of the hole, which accelerates the discharge of debris and prevents debris from adhering to the inner wall, thus achieving a cleaning effect and making this device have multiple functions.
