[0031] As a technical optimization of this utility model, a first protective plate 16 is set on the top of the grinding device base 1. The bottom of the first protective plate 16 is attached to the top of the placement plate 9, which can prevent the debris from splashing to areas outside the placement plate 9 during the grinding process. Two sets of second protective plates 17 are fixed at the bottom of the pressing plate 3 to further block the debris from splashing upward, thus ensuring the safety of the operator in all aspects and reducing the risk factors in the working environment.

[0032] The working principle and usage process of this utility model are as follows: In use, the tool to be sharpened is first placed on the placement plate 9 in the mounting groove 4. The placement plate 9 is precisely positioned by the cooperation of the limiting plate 52 in the limiting assembly 5 and the limiting groove 51 on the inner wall of the mounting groove 4, ensuring stable placement. Next, the pressing plate 3 is rotated and pressed down around the movable shaft 10 inside the side plate 2. The retaining plate 6 on the bottom right side of the pressing plate 3 is inserted into the top groove 7 on the top right side of the grinding device base 1. Simultaneously, the positioning rod 82 in the right positioning assembly 8 drives the positioning block 83 to move to the left under the action of the return spring 84, engaging with the right side of the retaining plate 6, thus fixing the pressing plate 3. The auxiliary plate 12 on the inner top of plate 2 serves to limit and support the top of the pressing plate 3. When the grinding operation is started, the debris generated during the process falls into the collection groove 13 on the top of the placement plate 9. After the operation is completed, pull the positioning rod 82 to the right to disengage the positioning block 83 from the clamping plate 6, and then lift the pressing plate 3 to remove the tool. If it is necessary to clean the collection groove 13 or maintain the device, the fixing bolts 15 on the bottom fixing plate 14 of the placement plate 9 can be unscrewed to disassemble the placement plate 9. During the entire operation, the first protective plate 16 on the top of the grinding device base 1 and the second protective plate 17 on the bottom of the pressing plate 3 work together to prevent debris from flying and ensure the safety of the operator.

[0033] In summary: This grinding device for sharpening cutting tools, by setting a limiting groove 51, a positioning sleeve 81, and a movable shaft 10, has limiting grooves 51 on both sides of the inner wall of the mounting groove 4. The limiting plate 52 is movably installed in the groove, and the placement plate 9 is placed in the mounting groove 4. The inner side of the limiting plate 52 is connected to the outer side of the placement plate 9. This design can accurately limit the position of the placement plate 9 in the mounting groove 4, ensuring that the placement plate 9 remains stable during use and providing reliable support for tool placement. The positioning sleeve 81 is fixed to the right side of the base 1 of the grinding device, and the positioning rod 82 moves on the right side of the positioning sleeve 81. One end can pass through the positioning sleeve 81 and enter the interior to connect with the positioning block 83. The return spring 84 is sleeved on the surface of the positioning rod 82 and located in the positioning sleeve 81. Its two ends are respectively attached to the right side of the positioning block 83 and the inner wall of the positioning sleeve 81. The positioning block 83 is movably inserted into the right side of the bottom clamping plate 6 of the pressing plate 3, firmly fixing the pressing plate 3. When adjustment is required... When the pressing plate 3 is in position, pull the positioning rod 82 to the right to disengage the positioning block 83 from the clamping plate 6, and the pressing plate 3 can be operated. Two sets of connecting plates 11 are fixed on the surface of the movable shaft 10. The right side of the connecting plate 11 is connected to the left side of the pressing plate 3, so that the pressing plate 3 can rotate flexibly around the movable shaft 10. The auxiliary plate 12 is fixed to the top of the inner side of the side plate 2, and its right side is attached to the top of the pressing plate 3. The auxiliary plate 12 plays a limiting and supporting role, ensuring the stability of the pressing plate 3 during rotation, making the pressing operation smoother. It solves the problem of not being able to collect the grinding debris, which would scatter indiscriminately, polluting the working environment and possibly mixing into the inside of the mechanical equipment, aggravating the wear of parts, shortening the service life of the equipment, and making cleaning time-consuming and laborious. If the tool cannot be effectively pressed and fixed, the tool is prone to displacement and shaking during grinding, resulting in uneven sharpening effect and inconsistent cutting edge quality, which greatly reduces the processing quality.
