[0002] Dentistry is one of the medical disciplines and is generally incorporated into the Department of Stomatology in large hospitals. Dentistry mainly treats diseases related to teeth and periodontal disease. In surgical tooth extraction, the patient's tooth root is long. When extracting teeth, the root is easily not stressed, and it is inconvenient to remove the broken root inside. Therefore, it is necessary to use pliers with a different shape from the traditional one. The pliers head of this pliers is a long beak type similar to the crown breaking pliers, that is, the pliers head is like a bird's beak. The front end is narrow and can penetrate deep into the broken root. The rear end grips the handle to apply force, so that the root is broken by force, and then it is taken out little by little with pliers. Therefore, this pliers is also called root breaking pliers.

[0003] The root pliers currently used for tooth extraction have a simple structure, and the angle between the pliers head and the pliers body is fixed and cannot be adjusted. Therefore, the root pliers are only suitable for specific usage environments. During the operation, when dealing with patients of different heights, or when performing dental operations in different parts of the oral cavity, because the angle of the pliers head of the root pliers cannot be adjusted, the doctor needs to change the position and angle of his or her arm or hand to change or adjust the angle position of the pliers head of the root pliers, thereby reducing the applicability and practicality of the root pliers.

[0027] Adjust the pliers head 4 according to the required angle, adjust the pliers head 4 to rotate to the required angle, and then use the insert block 6 to insert it into the slot 5 corresponding to the pliers head 4, so that the pliers head 4 can be fixed;

[0028] In surgical tooth extraction, the patient's tooth root is long. When extracting teeth, the tooth root is easily not stressed, and it is inconvenient to remove it if it is broken inside. Use the forceps head 4 to penetrate into the root fracture, and use the rear end grip to force the root to be broken by force, and then use the forceps head 4 to remove it little by little.

[0029] See also Figure 2 and Figure 6 , the limiting component includes a first spring 14, a connecting rod 8 and a pressing plate 9, the connecting rod 8 is fixedly connected between the pressing plate 9 and the plug block 6, the outer diameter of the connecting rod 8 is smaller than the outer diameter of the plug block 6, the first spring 14 is arranged at the end of the plug block 6 away from the connecting rod 8, and the first spring 14 is arranged on the inner wall of the pin groove 7, an annular groove 18 is opened on the outer side of the rotating rod 16, each slot 5 is formed on the inner wall of one side of the annular groove 18, and the plug block 6 is slidably connected with the annular groove 18;
