The symmetrically arranged arc-shaped adjusting rod 6 is located on both sides of the notch guard 3. Two moving blocks 7 are connected to the adjusting rod 6 and the limiting block 4 respectively. The steering component is connected to the notch guard 3. In use, the moving rod moves along the adjusting rod 6 to move the cutting blade 5, and the rotating component drives the limiting block 4 and the cutting blade 5 to rotate to adjust the angle.

[0022] Example 2

[0023] like Figures 2-4 As shown, the present invention proposes a tool sharpening processing device. Compared with Embodiment 1, this embodiment describes the detailed structure of the adjustment component and the steering component. The adjustment component also includes a fixed seat 8, a threaded rod 9 and an adjustment block 10. The number of fixed seats 8 is twice that of the adjustment rods 6. The fixed seats 8 are connected to both ends of the adjustment rods 6. The fixed seats 8 are connected to the notch protective cover 3. The number of threaded rods 9 corresponds to the number of adjustment rods 6. One end of the threaded rod 9 passes through the threaded hole on the moving block 7 and engages with the groove opened on the adjustment rod 6. The other end of the threaded rod 9 is connected to the adjustment block 10.

[0024] The steering assembly includes a rack 11, a support shaft 12, and a gear 13. There are two racks 11 symmetrically arranged. The rack 11 is connected to the fixed base 8. The rack 11 and the adjusting rod 6 have the same center and are both arc-shaped. The support shaft 12 is rotatably connected to the moving block 7. The support shaft 12 is connected to the limiting block 4. The two ends of the support shaft 12 are connected to the gears 13, which mesh with the rack 11 for transmission.

[0025] In an optional embodiment, each of the fixed teeth is provided with a receiving groove 14, and an elastic element 15 is connected in the receiving groove 14. One end of the elastic element 15 is connected to the cutting blade 5. The elastic element 15 is selected from, but is not limited to, a spring sheet.

[0026] In an optional embodiment, a support rod 16 is connected to the grinding wheel body 1, and a lighting lamp 17 is rotatably connected to the support rod 16; the support rod 16 is rotatably connected to the lighting lamp 17 through a damping shaft, which allows the lighting lamp 17 to be maintained at a fixed angle.

[0027] In an optional embodiment, a transparent protective plate 18 is provided on the notch guard 3; the protective plate 18 provides protection for the grinding wheel body 1 during normal turning, preventing the flying of grinding debris, while keeping the operator's view unobstructed.

[0028] In an optional embodiment, the notch protective cover 3 is composed of a protective cover body 19, a movable plate 20 and a fixed plate 21. The protective cover body 19 has a notch, a sliding plate is slidably connected to the notch, and a handle is connected to the sliding plate. The fixed plate 21 is connected to the inner wall of the protective cover body 19, and a sliding groove that cooperates with the sliding plate is provided on the fixed plate 21.

[0029] In summary, when using this utility model, the operator turns on the switch on the main body 1 of the grinding machine to rotate the grinding wheel 2. After wearing protective gear, the operator holds the tool to be sharpened close to the grinding wheel 2. The support plate on the notch guard 3 provides positioning for the operator's hand during grinding, providing additional support to prevent hand fatigue, shaking, and displacement. At the same time, the limiting block 4 provides additional protection for the fingers to prevent them from contacting the grinding wheel 2. If gloves, clothing, or hair accidentally get tangled on the grinding wheel 2, the movement of the grinding wheel 2 will cause the tangled item to move closer to the limiting block 4. The limiting teeth on the limiting block 4 guide the item, causing it to enter the two V-shaped cutting blades 5. The cutting blade 5 cuts the object. When the object comes into contact with the blade, the cutting blade 5 moves under the action of the elastic element 15, which can both buffer the impact and maintain continuous shearing pressure. When the rotation of the grinding wheel 2 needs to be reversed from the normal direction, the threaded rod 9 can be moved by rotating the adjusting block 10. The threaded rod 9 moves away from the groove on the adjusting rod 6 in the threaded hole on the moving block 7. Then, by pulling the adjusting rod 6, the moving block 7 moves along the adjusting rod 6. During the movement, the support shaft 12 connected to the limiting block 4 is driven to rotate by the meshing of the gears 13 and racks 11 at both ends of the shaft. The limiting block 4 thus rotates, so that it can adapt to different angles. After rotating to the position, the threaded rod 9 can be fixed by inserting it into the groove on the adjusting rod 6 again.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
