Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0032] like Figures 1 to 3 As shown, this utility model provides a high-precision adjustable sharpening device, including a bracket 2 and a sharpening mechanism 4 disposed on the bracket 2, which facilitates the sharpening of tools.

[0033] The bracket 2 is equipped with an adjustment mechanism 3 for adjusting the spatial position of the sharpening mechanism 4, which adjusts the height of the sharpening mechanism 4, and a clamping mechanism 5 for holding the blade. The clamping mechanism 5 is equipped with a rotating component, which rotates the clamping mechanism 5.

[0034] The adjustment mechanism 3 includes a fixed block 301 mounted on the bracket 2 and a movable block 302 slidably mounted on the fixed block 301. The adjustment mechanism 3 also includes an adjustment component for adjusting the spatial position of the movable block 302. The adjustment component includes a gear rod 303 rotatably mounted on the fixed block 301 and a rack 304 mounted on the movable block 302. The rack 304 meshes with the gear rod 303. By rotating the gear rod 303, the rack 304 and the movable block 302 are driven to make vertical linear movements, thereby adjusting the height of the grinding mechanism 4.

[0035] The movable block 302 includes a connecting block 306 disposed at one end near the fixed block 301. The fixed block 301 includes a dovetail groove 312 opened at one end near the movable block 302. The connecting block 306 is slidably connected to the inside of the dovetail groove 312, so that the movable block 302 and the fixed block 301 maintain vertical linear movement and there will be no deviation during the movement.

[0036] The top of the movable block 302 has a first through hole, and a rod 305 is inserted into the first through hole. A first threaded hole is provided on one side of the movable block 302, and a first limiting screw 307 that abuts against the rod 305 is threaded into the first threaded hole. The first limiting screw 307 limits the rod 305. When it is necessary to adjust the position of the rod 305, the first limiting screw 307 can be rotated in the opposite direction to release the limitation on the rod 305, so as to facilitate the adjustment of the position of the rod 305 in the movable block 302.

[0037] A slot 308 is provided on the side of the fixed block 301 near the moving block 302. A pressing plate 310 is inserted into the slot 308. A second threaded hole is provided on the side of the fixed block 301 away from the gear rod 303. A second limiting screw 309 is threadedly connected to the inside of the second threaded hole and abuts against the pressing plate 310. A limiting block 311 is provided on the side of the fixed block 301 between the connecting block 306 and the pressing plate 310. By rotating the second limiting screw 309, the second limiting screw 309 pushes the pressing plate 310 towards the limiting block 311, so that the limiting block 311 abuts against the connecting block 306, limiting the moving block 302 and the insert rod 305, preventing the grinding mechanism 4 from moving during operation and affecting the grinding accuracy.

[0038] The bracket 2 has a base plate 1 horizontally positioned at its bottom. The base plate 1 has round holes at each of its four corners. The base plate 1 can be fixed to the wooden board through the round holes to prevent the device from moving during use.

[0039] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When the height of the grinding mechanism 4 needs to be adjusted, the second limiting screw 309 is rotated, and the second limiting screw 309 moves away from the extrusion plate 310. The extrusion plate 310 will release the limiting block 311, so that the limiting block 311 moves away from the connecting block 306. At this time, the gear rod 303 is rotated as needed. When the gear rod 303 rotates, it will drive the connecting block 306 and the moving block 302 to move together through the rack 304, and drive the insertion rod 305 to move together. The insertion rod 305 drives the grinding mechanism 4 to move together. After the adjustment is completed, the second limiting screw 309 is rotated in the opposite direction, so that the second limiting screw 309 pushes the extrusion plate 310 to move, and the limiting block 311 abuts against the connecting block 306 to limit the moving block 302. Through the cooperation of the gear rod 303 and the rack 304, the precise control of the adjustment of the grinding mechanism 4 is realized, and the grinding quality of the tool is improved.

[0040] like Figure 4 and Figure 5As shown, the clamping mechanism 5 in this embodiment includes a base 501 disposed at one end of the top of the bracket 2. A second through hole is provided on one side of the base 501. A connecting rod 505 is inserted into the second through hole. An adjusting plate 510 is sleeved on the outside of the connecting rod 505. A sliding block 511 is slidably connected inside the adjusting plate 510. Clamping plates 512 are provided on both the upper and lower sides of the sliding block 511 away from the adjusting plate 510. The two clamping plates 512 are adjusted by fastening screws 513. By inserting the blade between the two clamping plates 512 and rotating the fastening screws 513, the blade is clamped and fixed.

[0041] The rotating assembly includes a lead screw 502 threadedly connected to one end of the connecting rod 505 located inside the second through hole. A first spring 503 is sleeved on the outer side of the lead screw 502. A baffle 504 is provided at the end of the lead screw 502 away from the connecting rod 505. A limiting ring 508 is provided at the end of the base 501 near the adjusting plate 510. A stop bar 506 is vertically arranged on the outer side of the connecting rod 505. A limiting groove 509 adapted to the stop bar 506 is opened on the side of the limiting ring 508 near the stop bar 506. The connecting rod 505 away from the lead screw 502... The end is threaded with a third limiting bolt 507 that abuts against the adjusting plate 510. When the baffle 504 is pressed, the baffle 504 compresses the first spring 503 and drives the connecting rod 505, the stop rod 506, the adjusting plate 510 and the blade to move together, so that the stop rod 506 moves away from the limiting groove 509. At this time, the blade is rotated 180° and the baffle 504 is released. The baffle 504 will reset under the action of the first spring 503, and drive the stop rod 506 to be inserted into the limiting groove 509, so that the blade is flipped over, which facilitates the grinding of the other side of the blade.

[0042] Two sliding holes 514 are provided on one side of the adjusting plate 510. A fourth limiting bolt 515 is slidably connected inside the sliding hole 514. The fourth limiting bolt 515 is threadedly connected to the sliding block 511. The sliding block 511 is fixed after the fourth limiting bolt 515 moves in the sliding hole 514 to adjust the position of the sliding bolt 511. This makes it easy to adjust according to the length of the blade and can better fix the blades of different lengths stably.

[0043] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: Rotating the fourth limiting bolt 515 releases the limiting of the sliding block 511. At this time, after adjusting the position of the sliding block 511 according to the blade length, rotating the fourth limiting bolt 515 in the opposite direction fixes the sliding block 511. The tool is placed between the upper and lower clamping plates 512. Rotating the fastening screw 513 fastens the two clamping plates 512, clamping the tool. When one side of the tool is finished, pressing the baffle 504 causes the baffle 504 to compress the first spring 503 and move the connecting rod 505, the stop rod 506, the adjusting plate 510 and the tool together, so that the stop rod 506 moves away from the limiting groove 509. At this time, rotating the tool 180° releases the baffle 504. The baffle 504 will reset under the action of the first spring 503, causing the stop rod 506 to be inserted into the limiting groove 509, flipping the tool to facilitate the grinding of the other side of the blade.

[0044] like Figure 6 As shown, the sharpening mechanism 4 in this embodiment includes a mounting ring 401 threaded to the top of the insert rod 305. The mounting ring 401 has a spherical bearing 402 inside, and a linear bearing 403 inside the spherical bearing 402. A sliding rod 404 is inserted into the linear bearing 403. The spherical bearing 402 and the linear bearing 403 allow the sliding rod 404 to slide smoothly back and forth, left and right, up and down, reducing resistance and improving accuracy. A first mounting block 405 and a second mounting block 406 are sleeved on the outer side of the sliding rod 404. A sharpening plate 407 is inserted between the first mounting block 405 and the second mounting block 406. The sharpening plate 407 is fixed by the first mounting block 405 and the second mounting block 406, facilitating the sharpening of the blade by the sharpening plate 407 and its replacement.

[0045] A knob 409 is threadedly connected to one end of the sliding rod 404 near the second mounting block 406. A second spring 408 is sleeved on the outside of the sliding rod 404. The two ends of the second spring 408 abut against the knob 409 and the second mounting block 406, respectively. By pulling the second mounting block 406, the second mounting block 406 compresses the second spring 408. At this time, the second mounting block 406 moves away from the grinding plate 407, making it convenient to disassemble and replace the grinding plate 407. After the grinding plate 407 is installed with the first mounting block 405, the second mounting block 406 is released. The second mounting block 406 will return to its original position under the action of the second spring 408, so that the second mounting block 406 abuts against the grinding plate 407. The grinding plate 407 is installed through the first mounting block 405 and the second mounting block 406.

[0046] The bottom of the mounting ring 401 is provided with a horizontal plate 410. One end of the top of the horizontal plate 410 is provided with a hook 411 that is compatible with the sliding rod 404. When it is necessary to replace the grinding plate 407, the sliding rod 404 is put on the hook 411, so that one end of the grinding plate 407 is tilted upward, which makes it easy to replace the grinding plate 407.

[0047] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: By adjusting the position of the sliding rod 404 in the linear bearing 403, the grinding plate 407 is brought into contact with the cutting tool. By swinging the sliding rod 404 back and forth, the sliding rod 404 drives the grinding plate 407 to move together, thus grinding the cutting tool. When it is necessary to replace the grinding plate 407, the sliding rod 404 is hung on the hook 411, and the second mounting block 406 is pulled. The second mounting block 406 compresses the second spring 408. At this time, the second mounting block 406 moves away from the grinding plate 407, making it convenient to replace. Remove and replace the grinding plate 407. After installing the grinding plate 407 with the first mounting block 405, loosen the second mounting block 406. The second mounting block 406 will return to its original position under the action of the second spring 408, so that the second mounting block 406 abuts against the grinding plate 407. The grinding plate 407 is installed through the first mounting block 405 and the second mounting block 406. The spherical bearing 402 and the linear bearing 403 facilitate the grinding of the tool by driving the grinding plate 407 through the sliding rod 404. The first mounting block 405 and the second mounting block 406 facilitate the quick replacement of the grinding plate 407.
