[0039] Please refer to Figures 1 to 8 , and now the holder provided by the present utility model will be described. The holder includes: a sphere 2, a rod body 1, a limiting ring body 13, and an elastic component 3; one end of the rod body 1 is a polygonal prism 11; a through hole 12 is provided on the polygonal prism 11; the two ends of the through hole 12 are respectively: a first opening 121 and a second opening 122; the first opening 121 is provided on one side surface of the polygonal prism 11, and the second opening 122 is provided on another side surface of the polygonal prism 11 and allows the sphere 2 to enter the through hole 12; the sphere 2 can be switched between an extended position and a retracted position along the through hole 12; the limiting ring body 13 is arranged around the inner wall of the edge of the first opening 121, and the inner side of the limiting ring body 13 has a limiting hole 131 smaller than the outer diameter of the sphere 2; the limiting ring body 13 is located on the sliding path of the sphere 2 along the through hole 12; the elastic component 3 is used to apply an elastic force to the sphere 2 so that the sphere 2 can move from the retracted position to the extended position; the elastic component 3 is arranged in the through hole 12; wherein, when the sphere 2 is in the extended position, the sphere 2 abuts against the limiting ring body 13, and a part of the sphere 2 passes through the limiting hole 131 and protrudes outside the polygonal prism 11; when the sphere 2 is in the retracted position, the sphere 2 retracts into the through hole 12.

[0040] Thus, the rod body 1 is provided with a polygonal prism 11, which can be inserted into a polygonal columnar cavity on the member to be rotated. When the user rotates the rod body 1, the member to be rotated can be rotated. A through hole 12 is formed in the polygonal prism 11. The two ends of the through hole 12 are respectively a first opening 121 and a second opening 122. The first opening 121 is formed on one side surface of the polygonal prism 11, and the second opening 122 is formed on another side surface of the polygonal prism 11. The sphere 2 can enter the through hole 12 from the second opening 122, and the sphere 2 can move between a protruding position and a retracted position in the through hole 12. An elastic component 3 is arranged in the through hole 12, and the elastic component 3 can apply an elastic force to the sphere 2 so that the sphere 2 can move from the retracted position to the protruding position. A limiting ring body 13 is arranged around the edge of the first opening 121, and a limiting hole 131 is formed inside the limiting ring body 13. The limiting ring body 13 is located on the sliding path of the sphere 2 along the through hole 12. When the external force is removed, the elastic component 3 can push the sphere 2 from the retracted position to the protruding position. After the sphere 2 reaches the protruding position, the sphere 2 is blocked by the limiting ring body 13, and a part of the sphere 2 passes through the limiting hole 131 on the limiting ring body 13 and protrudes outside the polygonal prism 11. When the polygonal prism 11 is inserted into a polygonal columnar cavity with a matching shape, the sphere 2 protruding outside the polygonal prism 11 can abut against the inner wall of the polygonal columnar cavity, reducing the probability of the member to be rotated falling off from the polygonal prism 11. When the sphere 2 is under an external force (such as the extrusion force of the inner wall of the polygonal columnar cavity on the sphere 2), the sphere 2 can be pushed from the protruding position to the retracted position. After the sphere 2 moves to the retracted position, it can retract into the through hole 12. After the sphere 2 retracts into the through hole 12, it can prevent the sphere 2 from interfering with the insertion of the polygonal prism 11 into the polygonal columnar cavity.

[0041] In one embodiment, the member to be rotated is an implant for dental restoration.

[0042] In one embodiment, the polygonal columnar cavity is a hexagonal prism cavity.

[0043] Further, please refer to Figures 1 to 8 , as a specific implementation manner of the holder provided by the present invention, the elastic component 3 includes: a spring 31 and a limiting member 32. The spring 31 is arranged in the through hole 12, and the limiting member 32 is fixed in the through hole 12. The spring 31 is clamped between the sphere 2 and the limiting member 32. Thus, under the elastic force of the spring 31, the spring 31 pushes the sphere 2 from the retracted position to the protruding position.

[0044] Further, please refer to Figures 1 to 8 , as a specific implementation manner of the holder provided by the present invention, the limiting member 32 closes the second opening 122. Thus, it is avoided that external objects enter the through hole 12 through the second opening 122, and the limiting member 32 can also prevent the sphere 2 from sliding out from the second opening 122.

[0045] Further, please refer to Figures 1 to 8 , as a specific embodiment of the holder provided by the present utility model, the limiting member 32 is detachably and fixedly connected to the rod body 1. In this way, the installation and disassembly of the limiting member 32 are facilitated.

[0046] Further, please refer to Figures 1 to 8 , as a specific embodiment of the holder provided by the present utility model, the limiting member 32 is threadedly connected to the rod body 1. In this way, the connection between the limiting member 32 and the rod body 1 is very convenient.

[0047] Further, please refer to Figures 1 to 8 , as a specific embodiment of the holder provided by the present utility model, the through hole 12 extends in a straight line direction. In this way, it is very convenient to form the through hole 12, and it is also convenient for the sphere 2 to move along the through hole 12.

[0048] Further, please refer to Figures 1 to 8 , as a specific embodiment of the holder provided by the present utility model, the extending direction of the through hole 12 is perpendicular to the axis of the rod body 1.

[0049] Further, please refer to Figures 1 to 8 , as a specific embodiment of the holder provided by the present utility model, the polygonal prism 11 is a hexagonal prism.

[0050] Further, please refer to Figures 1 to 8 , as a specific embodiment of the holder provided by the present utility model, the sphere 2 is an integral part made of gemstone. In this way, the gemstone is wear-resistant.

[0051] In one embodiment, the gemstone can be any one of the following: ruby, sapphire, diamond or jade.

[0052] In one embodiment, the limiting ring body 13 and the rod body 1 are an integral part.

[0053] Further, please refer to Figures 1 to 8 , as a specific embodiment of the holder provided by the present utility model, in the extending direction of the through hole 12 from the retracted position to the extended position, the inner diameter of the limiting hole 131 gradually narrows. In this way, the inner wall of the gradually narrowing limiting hole 131 is convenient for contacting the sphere 2.

[0054] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present utility model.
