[0032] In a preferred embodiment, the inner cavity of the left connecting card plate 1 is provided with a left limit block 51, and the inner cavity of the right connecting card plate 2 is provided with a right limit block 61. Through the setting of the left limit block 51 and the right limit block 61, the left limit block 51 and the right limit block 61 are stuck in the gap between the teeth, so that the left connecting card plate 1 and the right connecting card plate 2 cannot be displaced. The left limit block 51 and the right limit block 61 play a limiting role on the left connecting card plate 1 and the right connecting card plate 2.

[0033] In a preferred embodiment, the outer edge of the left limit block 51 is fixedly equipped with a left threaded column 5, and the outer edge of the right limit block 61 is fixedly equipped with a right threaded column 6. The left threaded column 5 is threadedly connected to the left transverse threaded hole 3, and the left threaded column 5 is rotated in the left transverse threaded hole 3, so that the left threaded column 5 can drive the left limit block 51 to be stuck in the gap between the teeth.

[0035] In a preferred embodiment, the outer edge of the connecting rod 12 fits tightly with the inner walls of the left connecting card plate 1 and the movable block 10, so that the connection between the left connecting card plate 1, the movable block 10 and the connecting rod 12 is more firmly connected and can be rotated. By removing the connecting rod 12, the movable block 10 and the connecting rod 12 can also be disassembled and cleaned.

[0036] In a preferred embodiment, a hexagonal groove 902 is provided on the outer edge of the double-headed internally threaded rod 901, and the hexagonal groove 902 is located in the middle of the double-headed internally threaded rod 901. Through the setting of the hexagonal groove 902, medical staff can accurately find the twisting point on the double-headed internally threaded rod 901 when using it. Twisting in the middle of the double-headed internally threaded rod 901 will be more stable, thereby improving the stability of the device.

[0037] In a preferred embodiment, the left threaded rod 903 and the right threaded rod 904 are respectively installed with a left hexagonal limit plate 905 and a right hexagonal limit plate 906 at one end away from the double-headed internal threaded rod 901, and the shape of the inner cavity of the left connecting sleeve 907 and the right connecting sleeve 908 is the same as the shape of the left hexagonal limit plate 905 and the right hexagonal limit plate 906. When the left connecting sleeve 907 and the right connecting sleeve 908 are fixed, rotating the double-headed internal threaded rod 901 will not cause the left threaded rod 903 and the right threaded rod 904 to rotate, and the left hexagonal limit plate 905 and the right hexagonal limit plate 906 can only slide in the left connecting sleeve 907 and the right connecting sleeve 908. Therefore, the left connecting card plate 1 and the right connecting card plate 2 can move to both sides, thereby improving the rationality of the device.

[0038] In a preferred embodiment, the diameters of the left hexagonal limit plate 905 and the right hexagonal limit plate 906 are larger than the diameters of the left threaded rod 903 and the right threaded rod 904, so that the left threaded rod 903 and the right threaded rod 904 cannot be detached from the left connecting sleeve 907 and the right connecting sleeve 908, thereby improving the stability of the device.

[0039] In a preferred embodiment, the inner wall of the left connecting sleeve 907 away from one end of the double-headed internal threaded rod 901 is provided with a left T-shaped block 909, the left T-shaped block 909 is rotatably connected to the left connecting sleeve 907, and the left T-shaped block 909 is installed on the left threaded head 911, and the inner wall of the right connecting sleeve 908 away from one end of the double-headed internal threaded rod 901 is provided with a right T-shaped block 910, the right T-shaped block 910 is rotatably connected to the right connecting sleeve 908, and the right T-shaped block 910 is installed on the right threaded head 912. The threaded rod 901 rotates counterclockwise, and the double-headed internally threaded rod 901 drives the left threaded rod 903 and the right threaded rod 904 to move toward the middle, and then the left thread head 911 and the right thread head 912 are rotated to make the left thread head 911 and the right thread head 912 disengage from the left internally threaded block 7 and the right internally threaded block 8 respectively. At this time, the entire connecting assembly 9 can be removed, making it simple and quick to separate the left connecting card plate 1 and the right connecting card plate 2 of the device, and convenient for the left connecting card plate 1 and the right connecting card plate 2 to be disassembled separately.

[0040] In a preferred embodiment, the length of the inner cavity of the left connecting sleeve 907 and the right connecting sleeve 908 is longer than the length of the left thread head 911 and the right thread head 912. When the left threaded rod 903 and the right threaded rod 904 are respectively retracted to the outermost ends of the left connecting sleeve 907 and the right connecting sleeve 908, there is a gap in the inner cavity of the left connecting sleeve 907 and the right connecting sleeve 908. At this time, by simultaneously rotating the left thread head 911 and the left connecting sleeve 907 and the right T-block 910 and the right connecting sleeve 908, the left thread head 911 is disengaged from the left internal thread block 7, and the right thread head 912 is disengaged from the right internal thread block 8.

[0041] Working principle: when in use, the left connecting card plate 1 and the right connecting card plate 2 are respectively set on both sides of the desired bone augmentation gap, and the left threaded column 5 is screwed to drive the left limit block 51 to contact the tooth gap, and then the right threaded column 6 is screwed to drive the right limit block 61 to contact the tooth gap, and then the movable block 10 and the movable block 2 11 on the left connecting card plate 1 and the movable block 10 and the movable block 2 11 on the right connecting card plate 2 are attached to the bone. , and then fix it, then screw the left thread head 911 into the left internal thread block 7, and then screw the right thread head 912 into the right internal thread block 8. When adjusting, fix the left connecting sleeve 907 and the right connecting sleeve 908, and then rotate the double-headed internal thread rod 901 to drive the left thread rod 903 and the right thread rod 904 to move outward. The outward movement of the left thread rod 903 and the right thread rod 904 will respectively push the left connecting sleeve 907, the left hexagonal limit plate 905, and the left T-shaped block 9 09, the left thread head 911, the left internal thread block 7, the left connecting card plate 1 and the right connecting sleeve 908, the right hexagonal stopper 906, the right T-shaped block 910, the right thread head 912, the right internal thread block 8 and the right connecting card plate 2 are moved to increase the distance between the left connecting card plate 1 and the right connecting card plate 2. Regular adjustments can be made. When disassembling, the left connecting sleeve 907 and the right connecting sleeve 908 are fixed, and the left connecting sleeve 907 is fixed to the right connecting sleeve 908 by rotating the double-headed internal thread rod 901 in the opposite direction. The threaded rod 903 and the right threaded rod 904 move toward the middle. At this time, the left connecting sleeve 907 and the right connecting sleeve 908 are in a cavity state. At this time, by rotating the left thread head 911 and the left connecting sleeve 907 and the right connecting sleeve 908 and the right thread head 912, the left thread head 911 and the right thread head 912 are respectively separated from the left internal thread block 7 and the right internal thread block 8. At this time, the entire connecting assembly 9 is disassembled, and then the left connecting clamp 1 and the right connecting clamp 2 can be disassembled.
