The starting of the second motor 206 and the first motor 205 drives the first moving plate 203 to move under the driving force of the first threaded rod 201 and the guiding force of the second threaded rod 202. This, in turn, drives the second moving plate 204 to move under the driving force of the spring 303 and the guiding force of the first threaded rod 201. This causes the outer side of the support plate 209 to fit against the outer side of the grinding cylinder 4. The two sets of support plates 209 clamp and fix the grinding cylinder 4. A drill bit is connected via a connector, which drives the third threaded rod 211 to rotate, causing the inner support plate 212 to move until it fits against the inner side of the grinding cylinder 4, thus grinding the grinding cylinder 4.

By controlling the rotation of the second motor 206 and the first motor 205, the first motor 205 is reversed, causing the first moving plate 203 and the second moving plate 204 to move in the same direction to grind the blade 308. The starting of control 207 drives a set of rotating rods 208 to rotate, which in turn drives the rotating plate 210 to rotate, thus rotating the grinding cylinder 4. This allows for different degrees of grinding of the blade 308, making it easy to adapt to different grinding requirements and expanding its application range.
[0016] The flipping mechanism 3 includes a fixed plate 301, an adjusting plate 302, a spring 303, a push plate 304, a pressure block 305, a fixed rod 306, a connecting plate 307, a blade 308, a second spring 309, a threaded cylinder 310, and a knob 311. A fixed plate 301 is fixedly installed on the top of the mounting platform 1.

A push plate 304 is fixedly installed on the top of the adjusting plate 302. The top of the fixed plate 301 has two sets of mounting openings, and a pressure block 305 is installed in each mounting opening. Two sets of second springs 309 are fixedly installed between the pressure block 305 and the fixed plate 301. The top of the adjusting plate 302 has a through hole, and a fixing rod 306 is fixedly installed in the through hole. A connecting plate 307 is rotatably installed on the outside of the fixing rod 306. Two sets of baffles are fixedly installed on the inside of the movable opening. The outside of the connecting plate 307 fits against the outside of the baffles. A slot is opened on the outside of the connecting plate 307, and a blade 308 is installed in the slot. A threaded cylinder 310 is fixedly installed on the outside of the slot. The threaded cylinder 310 is C The outer side of the fixing plate 301 is threaded with a knob 311. The outer side of the knob 311 is in contact with the outer side of the connecting plate 307. When the blade 308 is placed on the outer side of the support plate 209, a set of pressure blocks 305 is pressed, so that the set of pressure blocks 305 is placed in the installation opening. This pushes the push plate 304 to move the adjusting plate 302, compresses the spring 303, and drives another set of pressure blocks 305 to be placed in another set of installation openings, fixing the adjusting plate 302. This causes the connecting plate 307 to move and rotate on the outer side of the fixing rod 306, tilting the connecting plate 307 to the other side. The outer side of the connecting plate 307 is in contact with the outer side of the baffle, allowing switching between the front and back sides of the blade 308 for grinding. This facilitates double-sided grinding of the blade 308, reduces the need to disassemble the blade 308, and improves work efficiency.
[0017] Furthermore, the grinding cylinder 4 is positioned between the two sets of support plates 209. The inner side of the grinding cylinder 4 is in contact with the outer side of the inner support plate 212. One side of the inner support plate 212 has a right-angled triangle cross section. The outer side of the third threaded rod 211 is provided with two sets of threads, which are in opposite directions. A connector is fixedly installed on the outer side of the third threaded rod 211. The structure is simple and easy to use.
[0018] Working principle: A blade 308 is installed in the slot of the connecting plate 307. A knob 311 is threaded onto the outer side of the threaded cylinder 310, so that the outer side of the knob 311 fits against the outer side of the blade 308 and the connecting plate 307 to fix the blade 308. By setting a grinding cylinder 4 between the two sets of support plates 209, the starting of the second motor 206 and the first motor 205 is controlled, which drives the first moving plate 203 to move under the driving action of the first threaded rod 201 and the guiding action of the second threaded rod 202, and drives the second moving plate 204 to move under the driving action of the spring 303. Guided by the first threaded rod 201, the outer side of the support plate 209 is brought into contact with the outer side of the grinding cylinder 4. The two sets of support plates 209 clamp and fix the grinding cylinder 4. The drill bit is connected through the connector, which drives the third threaded rod 211 to rotate, causing the inner support plate 212 to move to contact the inner side of the grinding cylinder 4, further fixing the grinding cylinder 4. The start of control 213 drives the rotating rod 208 to rotate, which in turn drives the grinding cylinder 4 to rotate and switch between different grit sandpaper on the outer side of the grinding cylinder 4. By controlling the rotation of the second motor 206 and the first motor 205, the first... Motor 205 reverses, driving the first moving plate 203 and the second moving plate 204 to move in the same direction to grind the blade 308. The start of the third motor 207 drives a set of rotating rods 208 to rotate, which in turn drives the rotating plate 210 to rotate the grinding cylinder 4. This allows for different levels of grinding of the blade 308, adapting to various grinding requirements, expanding its applicability, reducing the frequency of sandpaper changes, and improving the device's effectiveness. By pressing a set of pressure blocks 305 when the blade 308 is positioned on the outside of the support plate 209, the pressure blocks 305 are set... Within the installation opening, push the push plate 304 to move the adjusting plate 302, compressing the spring 303. This causes another set of pressure blocks 305 to be positioned within another installation opening, fixing the adjusting plate 302. This moves the connecting plate 307, causing it to rotate outside the fixing rod 306, tilting it to the other side. The outer side of the connecting plate 307 then mates with the outer side of the baffle, allowing for switching between the front and back sides of the blade 308 for grinding. This facilitates double-sided grinding of the blade 308, reduces the need for disassembly, and features a simple structure, ease of use, and improved work efficiency.
