[0032] Please see the appendix Figures 1 to 3 A clamping device for assisting jawbone grinding in one embodiment of the present invention includes a first opening and closing arm 10, a second opening and closing arm 20 and an angle adjustment mechanism 30, wherein the second opening and closing arm 20 is hinged to the first opening and closing arm 10 so that the opening 210 between the second opening and closing arm 20 and the first opening and closing arm 10 is adjustable.

[0033] The angle adjustment mechanism 30 includes a first clamping plate 310, a first connecting rod 320, an operating rod 330, and a spring 340. The first connecting rod 320 includes a first prism segment 321 and a second segment 322 connected sequentially along its extension direction. The first clamping plate 310 is located within the opening 210 and connected to the end of the first connecting rod 320. The first opening / closing arm 10 has a polygonal through hole 110 matching the first prism segment 321. The second segment 322 passes through the polygonal through hole 110 and extends out of the first opening / closing arm 10. The operating rod 330 is connected to the end of the second segment 322 away from the first prism segment 321. The spring 340 is sleeved on the outer periphery of the first connecting rod 320 and abuts against the first clamping plate 310 and the first opening / closing arm 10.

[0034] When the first prism segment 321 is located within the polygonal through hole 110, the first clamping plate 310 is in a circumferentially limited state; when the first prism segment 321 is dislodged from the polygonal through hole 110, the first clamping plate 310 is in a circumferentially rotatable state.

[0035] Specifically, the first opening arm 10 and the second opening arm 20 of this application are connected by a hinge, and the interval between the openings 210 is adjustable. The opening degree of the first opening arm 10 and the second opening arm 20 can be adjusted as needed to adapt to the grinding needs of different sized jawbones or different grinding objects. The first prism segment 321 has a polygonal cross section that matches the polygonal through hole 110 on the first opening arm 10, so that when the first prism segment 321 is inserted into the polygonal through hole 110, circumferential limiting can be achieved. In this position, the first prism segment 321 cannot rotate in the polygonal through hole 110, thereby preventing the first clamping plate 310 from rotating in the opening 210.

[0036] As a preferred example, the first prism segment 321 is cuboid in shape, and the polygonal through hole 110 is a quadrilateral hole; the first clamping plate 310 and the second clamping plate 510 are both circular plates; the second segment 322 is cylindrical.

[0037] Spring 340 is sleeved on the outer periphery of first connecting rod 320 and abuts between first clamping plate 310 and first opening and closing arm 10. Spring 340 can provide a restoring force. For example, when it is necessary to clamp the jawbone, after gripping the first gripping part 130 and the second gripping part 230, spring 340 is in a compressed state. When it is necessary to adjust the grinding position of the jawbone, the gripping force of the first gripping part 130 and the second gripping part 230 can be slightly released. Under the restoring action of spring 340, the first prism segment 321 can slowly exit from the polygonal through hole 110. At this time, by rotating the operating rod 330, the first clamping plate 310 can be rotated, thereby realizing the adjustment of the jawbone grinding position.

[0038] In another embodiment, the polygonal through hole 110 may also be formed on the second opening and closing arm 20, which can be set according to actual needs.

[0039] Workflow: When the cut jawbone needs to be dimensionally ground, the jawbone to be ground is first placed between the first clamping plate 310 and the second clamping part 220 (or the second clamping plate 510). The first gripping part 130 and the second gripping part 230 are gripped tightly, and the spring 340 is gradually compressed. At this time, the opening 210 between the first clamping part 120 and the second clamping part 220 narrows and becomes smaller. The first prism segment 321 gradually enters the polygonal through hole 110. At this time, the jawbone to be ground is in a stable clamping state. Then, the jawbone to be ground is ground by the grinding device. When the jawbone edge has been polished to a certain size and it is time to switch to another edge, the operator slightly releases the gripping force. Under the reset action of the spring 340, the first prism segment 321 gradually exits from the polygonal through hole 110. Since the spring 340 has a certain reset force, the jawbone remains slightly clamped between the first clamping plate 310 and the second clamping plate 510 during the exit process. The first prism segment 321 is not circumferentially limited at this time. By rotating the operating rod 330 to a certain angle that matches the polygonal through hole 110, the jawbone is also rotated synchronously by a certain angle. For example, when the polygonal through hole 110 is a quadrilateral through hole, rotate 90° and then grip the first gripping part 130 and the second gripping part 230 tightly. The first prism segment 321 re-enters the polygonal through hole 110, and the next edge of the jawbone can be polished. In this way, the polishing of the entire jawbone can be completed.

[0040] By adjusting the opening and closing degree of the clamping arm and the angle of the first clamping plate 310, this device can adapt to jawbones of different sizes and shapes or grinding needs, improving the flexibility of use. When the first prism segment 321 is inserted into the polygonal through hole 110, the clamping plate is in a circumferentially limited state, ensuring the stability and reliability of clamping. The operator can adjust the angle of the clamping plate by operating the operating rod 330, which is simple and convenient. This application is not only suitable for jawbone grinding, but can also be applied to other occasions that require clamping and grinding, and has high versatility and applicability.

[0041] In a preferred embodiment, the first opening and closing arm 10 has a first through hole (not shown in the figure) through which the pin 40 passes, and the second opening and closing arm 20 has a second through hole (not shown in the figure) through which the pin 40 passes. The second opening and closing arm 20 is hinged to the first opening and closing arm 10 through the first through hole and the second through hole via the pin 40 passing through the first through hole and the second through hole.

[0042] The pin 40 divides the first opening and closing arm 10 into a first clamping part 120 and a first gripping part 130. The pin 40 also divides the second opening and closing arm 20 into a second clamping part 220 and a second gripping part 230. The first clamping part 120 and the second clamping part 220 are arranged opposite each other, as are the first gripping part 130 and the second gripping part 230. The top end of the first clamping part 120 is bent away from the side of the second clamping part 220, and the top end of the second clamping part 220 is bent away from the side of the first clamping part 120. The polygonal through hole 110 is formed in the first clamping part 120.

[0043] Specifically, the first opening arm 10 and the second opening arm 20 are respectively provided with a first through hole and a second through hole. The pin 40 passes through these two through holes, thereby hinged the second opening arm 20 to the first opening arm 10. The hinged connection allows the spacing between the openings 210 (and the opening 210 corresponding to the object to be polished) to be adjustable. The top of the first clamping part 120 is bent away from the second clamping part 220, and the top of the second clamping part 220 is also bent away from the other. The bending design increases the clamping area and clamping force of the clamping part, enabling the device to better adapt to and clamp jawbones of different shapes.

[0044] In a preferred embodiment, the device further includes a second clamping plate 510 and a second connecting rod 520 disposed within the opening 210. The second connecting rod 520 includes a first end (not shown) and a second end (not shown) disposed opposite each other along its own extending direction. The first end is connected to the second clamping portion 220, and the second clamping plate 510 is connected to the second end. The second clamping plate 510 and the first clamping plate 310 are disposed directly opposite each other. Using the first clamping plate 310 and the second clamping plate 510 can increase the clamping area, better adapt to jawbones of different sizes and shapes, and help improve the efficiency and effect of grinding.

[0045] In a preferred embodiment, the first clamping plate 310 and the first prism segment 321 are integrally formed, and the second segment 322 has an external thread (not shown) at one end near the first prism segment 321. The first prism segment 321 has a threaded hole (not shown) for the second segment 322 to be connected, and the first clamping plate 310 and the second segment 322 are threadedly connected.

[0046] Specifically, the one-piece molding improves the structural strength of the entire clamping device. The second segment 322 has an external thread at one end near the first prism segment 321, while the first prism segment 321 has a threaded hole for the second segment 322 to connect to. The threaded connection can achieve a stable connection between the first clamping plate 310 and the second segment 322. In addition, the threaded connection facilitates maintenance and replacement. For example, if any part of the clamping plate or connecting rod is damaged, the operator can unscrew the first prism segment 321 and the second segment 322 in reverse to easily replace the damaged part without replacing the entire clamping device, thus extending the service life of the clamping device.

[0047] Furthermore, the second clamping plate 510 and the second connecting rod 520 are integrally formed.

[0048] Furthermore, the outer diameter of the second segment 322 is smaller than the outer diameter of the first prism segment 321.

[0049] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
