Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-4, A dental implant abutment placement tool provided by the utility model includes: a box body 1, and further includes: two elastic clamping members 2 fixed to one side of the outer wall of the bottom of the box body 1. Sliding openings 3 are formed on the outer walls on both sides of the box body 1, and the same moving plate 4 is slidably connected to the inner walls of the two sliding openings 3. A hexagonal prism 5 is inserted into one side of the outer wall of the bottom of the box body 1 through a bearing, and a driven bevel gear 6 is fixed to the outer wall of the top of the hexagonal prism 5. A main driving member 7 is installed on the inner wall of the box body 1, and a compression spring 8 is arranged on one side of the moving plate 4. Pulling ropes 9 are connected to the outer walls of the two elastic clamping members 2, and the two pulling ropes 9 are respectively connected to both ends of the moving plate 4. Fixed pulleys 10 are fixed to the outer walls on both sides of the box body 1, and the two pulling ropes 9 respectively form a sliding fit with the two fixed pulleys 10.

[0020] It should be noted here that: by pulling the moving plate 4, the two pulling ropes 9 can be pulled. During the movement of the moving plate 4, the compression spring 8 is compressed.

[0022] It should be noted here that: the two pulling ropes 9 can pull the two inclined arc plates 204 at the same time, so that the two inclined arc plates 204 expand outward from the bottom end. At this time, the abutment body 11 can be placed between the two arc plates 202, and then the two pulling ropes 9 are released. The two inclined arc plates 204 are respectively reset under the action of the two spring hinges 203 and wrap around the outer wall of the abutment body 11.

[0023] In a preferred embodiment, the main driving member 7 includes a driving motor 701, a fixing plate 702, a rotating shaft 703 inserted on the outer wall of one side of the fixing plate 702 through a bearing, and a driving bevel gear 704 fixed to one end of the rotating shaft 703, and the output shaft of the driving motor 701 is connected to one end of the rotating shaft 703.

[0024] It should be noted here that the driving motor 701 can drive the rotating shaft 703 to rotate, and then drive the driving bevel gear 704 to rotate.

[0025] In a preferred embodiment, the tooth ratio of the driving bevel gear 704 to the driven bevel gear 6 is 1:1.5, and the driving bevel gear 704 meshes with the driven bevel gear 6.

[0026] It should be noted here that the rotation of the driving bevel gear 704 can drive the driven bevel gear 6 to rotate.

[0027] In a preferred embodiment, one end of the compression spring 8 away from the moving plate 4 is fixed on the fixing plate 702.

[0028] It should be noted here that it plays a role in fixing one end of the compression spring 8 so that the compression spring 8 can be stressed.

[0029] In a preferred embodiment, one end of the pulling rope 9 away from the moving plate 4 is fixedly connected to the inclined arc plate 204.

[0030] It should be noted here that the pulling rope 9 can pull the inclined arc plate 204.

[0031] Working principle: The two pulling ropes 9 can be pulled by dragging the moving plate 4. During the movement of the moving plate 4, the compression spring 8 is compressed. The two pulling ropes 9 are used to pull the two inclined arc plates 204 at the same time, so that the two inclined arc plates 204 are unfolded outward from the bottom end. At this time, the base body 11 can be placed between the two arc plates 202, and the hexagonal prism 5 is inserted into the groove at the top of the base body 11. Then the moving plate 4 is released. Under the action of the compression spring 8, the moving plate 4 returns to its original position. The two pulling ropes 9 lose their pulling force, and the two inclined arc plates 204 return to their original positions under the action of the two spring hinges 203 respectively, covering the outer wall of the base body 11, and at the same time not affecting the rotation of the base body 11;

[0032] At this time, the end of the box body 1 with the base body 11 at the bottom can be inserted into the patient's oral cavity. The bottom of the base body 11 can be placed on the implant. By driving the motor 701, the rotating shaft 703 can be driven to rotate, and then the driving bevel gear 704 can be driven to rotate, and then the driven bevel gear 6 and the hexagonal prism 5 can be driven to rotate, and then the base body 11 can be driven to rotate, and the threaded rod at the bottom of the base body 11 can be screwed into the implant. After the base body 11 is placed and fixed, the moving plate 4 can be pulled again to pull the two pull ropes 9, so that the two inclined arc plates 204 are unfolded outward from the bottom end. At this time, the two inclined arc plates 204 can be taken away from the base body 11, and the box body 1 can be taken out of the patient's oral cavity. Only one tool is needed to complete the installation of the base body 11, which is more convenient.
