[0031] The bottom of the main body 1 is rotatably connected to a turntable 15, and the top of the turntable 15 is fixedly connected to a connecting rod, which rotatably penetrates the bottom surface of the main body 1. The top of the connecting rod extending into the inside of the main body 1 is fixedly connected to a third gear 14, which meshes with a fourth gear 16. The third gear 14 is slidably matched with the bottom surface of the inner cavity of the main body 1, and the third gear 14 is positioned in the main body 1.

[0032] Four second sliding blocks 11 are slidably disposed on the support plate 7 , and the four second sliding blocks 11 are distributed in a circular array about the middle of the support plate 7 .

[0033] Four second sliding grooves 23 are formed on the support plate 7 , and the four second sliding blocks 11 are slidably connected to the corresponding second sliding grooves 23 .

[0034] A driving assembly is arranged inside the main body 1, and a transmission assembly is arranged on the support plate 7. The driving assembly cooperates with the transmission assembly to drive the four second sliders 11 to move toward or away from each other. The four second sliders 11 move toward each other to clamp the oilstone.

[0035] The transmission assembly includes a second gear 10. A fixing plate 21 is fixedly connected to the top of the support plate 7, a worm 6 is rotatably connected to the fixing plate 21 via a bearing, and one end of the worm 6 is fixedly connected to the first gear 5.

[0036] The support plate 7 is rotated inside with a rotating shaft 9, which is arranged vertically. The top of the rotating shaft 9 extending above the support plate 7 is fixedly sleeved with a worm gear 22, which meshes with the worm 6. The second gear 10 is fixedly connected to the bottom of the rotating shaft 9 extending below the support plate 7.

[0037] A circular plate 12 is rotatably connected to the bottom of the support plate 7 . A ring gear 13 is fixedly sleeved on the bottom end of the circular plate 12 . The ring gear 13 meshes with the second gear 10 .

[0038] The upper surface of the circular plate 12 is provided with latching teeth, which are distributed in a spiral shape. The bottom of each second slider 11 is provided with a plurality of latching grooves, which are latched on the corresponding latching teeth. When the circular plate 12 rotates, the latching teeth drive the second slider 11 to slide in the corresponding second slide groove 23.

[0039] The driving assembly includes a rack 4, which is arranged vertically and fixedly connected to the inner wall of the main body 1. When the first gear 5 moves to contact with the rack 4, the first gear 5 meshes with the rack 4.

[0040] The second slider 11 is provided with a sliding rod 20 slidably disposed inside, and both ends of the sliding rod 20 extend out of the second slider 11. A clamping plate 19 is fixedly connected to one end of the sliding rod 20 close to the middle of the support plate 7, and a spring 18 is fixedly connected between the clamping plate 19 and the corresponding second slider 11, and the spring 18 is sleeved on the corresponding sliding rod 20. The bottom surface of the clamping plate 19 is slidably matched with the upper surface of the support plate 7.

[0041] A positioning component for positioning the oilstone is arranged on the top of the main body 1 .

[0042] The positioning assembly includes four first sliders 3. Four first slide grooves 2 are provided on the top surface of the main body 1. The four first slide grooves 2 are arranged in a circular array about the middle of the support plate 7. The four first sliders 3 are slidably connected in the corresponding first slide grooves 2. The first sliders 3 correspond to the second sliders 11 one by one, and a telescopic rod 17 is fixedly connected between the bottom surface of the first slider 3 and the corresponding clamping plate 19. When the second slider 11 slides, the corresponding first slider 3 is driven to slide together through the telescopic rod 17.

[0043] The telescopic rod 17 includes a sleeve and a connecting rod, wherein the sleeve is fixedly connected to the top of the clamping plate 19, the connecting rod is fixedly connected to the bottom of the first slider 3 corresponding to the clamping plate 19, and one end of the connecting rod is slidably connected to the inside of the sleeve. When the support plate 7 drives the clamping plate 19 to move up and down, the sleeve will slide on the connecting rod, thereby changing the length of the entire telescopic rod 17.

[0044] The adjacent ends of the four first sliders 3 are each provided with a groove 25, and the inside of the groove 25 is rotatably connected with a pulley 24. The diameter of the middle part of the pulley 24 is greater than the depth of the groove 25, so that the middle part of the pulley 24 will extend out of the groove 25. When the oil stone is moved into the inside of the main body 1, the oil stone will slide down along the pulley 24, and the pulley 24 will be driven to rotate during the sliding, so as to position the oil stone and reduce wear.

[0045] Working principle:

[0046] In the initial state, the first gear 5 is located at the top of one side of the rack 4, and the teeth on the first gear 5 are about to mesh with the rack 4. At this time, the distance between the four clamping plates 19 is the largest.

[0047] Move the oil stone and pass it between the four pulleys 24 until the bottom surface of the oil stone contacts the support plate 7 , so that the bottom end of the oil stone is located between the four clamping plates 19 .

[0048] The turntable 15 is rotated forward, driving the third gear 14 to rotate, causing the fourth gear 16 and the screw 8 to rotate. The screw 8 rotates inside the support plate 7, driving the support plate 7 to slide downward inside the main body 1, driving the clamping plate 19, the second slider 11, and the first gear 5 to move downward together. Under the action of gravity, the oilstone will move downward together with the support plate 7. The support plate 7 will pull the sleeve of the telescopic rod 17 downward, causing the entire telescopic rod 17 to extend.

[0049] When the first gear 5 moves downward, the rack 4 drives the first gear 5 to rotate, so that the worm 6 rotates, and the worm 6 drives the worm wheel 22 to rotate, driving the rotating shaft 9 and the second gear 10 to rotate.

[0050] The second gear 10 drives the ring gear 13 to rotate, so that the circular plate 12 rotates. The latch teeth on the circular plate 12 drive the second sliders 11 to slide in the second slide slots 23 toward the middle of the support plate 7, so that the four second sliders 11 move toward each other.

[0051] The second slider 11 pushes the corresponding clamping plate 19 to slide together through the spring 18 , and the clamping plate 19 slides on the upper surface of the support plate 7 , and at the same time drives the slide bar 20 to slide together.

[0052] The clamping plate 19 drives the corresponding first sliding block 3 to slide inside the first sliding groove 2 through the telescopic rod 17, so that the four first sliding blocks 3 move toward each other.

[0053] When the clamping plate 19 contacts the oil stone, the second slider 11 continues to move, and the second slider 11 slides on the slide bar 20 and compresses the corresponding spring 18, so that the clamping plate 19 abuts against the side of the oil stone. The clamping plate 19 clamps and fixes the oil stone, and the pulley 24 also contacts the side of the oil stone. The pulley 24 positions the end of the oil stone extending outside the main body 1.

[0054] The support plate 7 continues to move downward, causing the first gear 5 to move downward away from the rack 4, and the first gear 5 stops rotating. The oilstone continues to move downward along with the support plate 7, which is suitable for clamping oilstones of different lengths.

[0055] After the oilstone is processed, the turntable 15 is rotated in the opposite direction to rotate the screw rod 8, and the support plate 7 slides upward inside the main body 1, which pushes the oilstone to slide upward between the four pulleys 24. The support plate 7 pushes the sleeve on the telescopic rod 17 upward to shorten the entire telescopic rod 17.

[0056] When the first gear 5 moves to the bottom of one side of the rack 4, the teeth on the first gear 5 are about to mesh with the rack 4. The first gear 5 continues to move upward, the rack 4 drives the first gear 5 to rotate, and the circular plate 12 rotates. At this time, the locking teeth on the circular plate 12 drive the four second sliders 11 to move in opposite directions.

[0057] Under the action of the spring 18, the clamping plate 19 continues to abut against the side of the oil stone, and the second slider 11 slides on the slide bar 20. When the spring 18 returns to its natural state, the second slider 11 pulls the spring 18, the clamping plate 19 and the slide bar 20 to slide together, so that the clamping plate 19 leaves the oil stone. At the same time, the clamping plate 19 drives the first slider 3 to slide together through the telescopic rod 17.

[0058] When the clamping plate 19 is separated from the oil stone, the oil stone will slide toward the outside of the main body 1 until the first gear 5 is moved to the top of one side of the rack 4 and restored to the initial state. The oil stone can be taken out upwards.

[0059] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
