[0021] A clamp head 17 is provided at the lower end of the lower housing 1 , and a lifting assembly for clamping and loosening the clamp head 17 is provided inside the lower housing 1 .

[0022] In this embodiment, when the doctor needs to perform tooth extraction treatment on the patient, he can hold the lower shell 1 with one hand and the upper shell 2 with the other hand to rotate and adjust the angle. In this way, the purpose of rotation can be achieved and the position angle required by the doctor can be adjusted. Then the tooth extraction forceps can be placed into the patient's mouth, the patient's teeth can be clamped by the forceps head 17, and the teeth can be extracted.

[0023] It is worth noting that the lower surface of the pinching block 5 is movably provided with rubber 20, and the rubber 20 is provided with anti-skid grooves. The rubber 20 is a non-toxic and harmless natural material. The anti-skid grooves on the rubber 20 are for the doctor to better hold the dental forceps during the treatment process.

[0024] Embodiment 2, based on the above embodiment:

[0025] See also Figure 1-Figure 3 The handle 3 is rotatably connected to a first rotating column 4, the surface of the first rotating column 4 is rotatably connected to a rotating shaft 6, a pinch block 5 is fixedly connected to the side of the rotating shaft 6, and an end of the pinch block 5 away from the rotating shaft 6 is fixedly connected to a connecting block 7;

[0026] A first limiting ring 11 is fixedly connected to the inner wall of the upper shell 2, a first connecting rod 10 is slidably connected to the inner wall of the first limiting ring 11, a fixed block 9 is fixedly connected to the upper end face of the first connecting rod 10, a sliding groove 91 is provided on the side of the fixed block 9, a second rotating column 8 is slidably connected to the inner wall of the sliding groove 91, and the side of the second rotating column 8 is fixedly connected to the side of the connecting block 7.

[0027] In this embodiment, during use, Figure 2 Taking the middle direction as an example, when the doctor pinches the pinching block 5, the pinching block 5 moves upward in a circular trajectory, thereby causing the connecting block 7 to move in a circular trajectory, and this displacement is limited by the first rotating column 4. Through the circular trajectory displacement of the connecting block 7, the fixed block 9 can be vertically displaced, so that the first connecting rod 10 can be vertically displaced, and this displacement is limited by the first limiting ring 11.

[0028] It is worth noting that a slide groove 91 is provided on the fixed block 9 , and during the above displacement process, the second rotating column 8 slides along the inner wall of the slide groove 91 .

[0029] Embodiment 3, based on the above embodiment:

[0030] See also Figure 3-Figure 4 The lifting assembly includes a second limiting ring 12, which is fixedly arranged on the inner wall of the lower shell 1, and the inner wall of the second limiting ring 12 is slidably connected with a second connecting rod 13, and the side of the second connecting rod 13 is movably connected with a spring 14, the upper end of the spring 14 is fixedly connected to the lower surface of the second limiting ring 12, and the lower end surface of the second connecting rod 13 is fixedly connected with a gear ring column 15, and the lower end of the spring 14 is fixedly connected to the upper surface of the gear ring column 15;

[0031] Two sets of mounting plates 16 are fixedly provided on the side of the lower shell 1, and the interior of the two sets of mounting plates 16 is fixedly connected with a third rotating column 18.

[0032] In this embodiment, in actual use, Figure 3Taking the middle direction as an example, since the first connecting rod 10 is displaced in the longitudinal direction, the second connecting rod 13 can be synchronously driven to be displaced in the longitudinal direction, and this displacement is limited by the second limiting ring 12. Through the longitudinal displacement of the second connecting rod 13, the toothed ring column 15 can be longitudinally displaced, and through the cooperation of the second connecting rod 13 and the spring 14, the toothed ring column 15 can be reciprocated in the vertical direction. In this way, the fan-shaped gear 19 can be displaced in a reciprocating circular trajectory through the transmission of the toothed ring column 15, so that when the doctor pinches the pinch block 5, the forceps head 17 will clamp the patient's teeth, and when the doctor releases the pinch block 5, the forceps head 17 will release the patient's teeth.

[0033] It is worth noting that the two clamp heads 17 are fixed to the lower end of the lower housing 1 through two sets of mounting plates 16 and two third rotating columns 18 .
