[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] 1. The utility model achieves the goal of replacing the pliers head of orthodontic pliers separately after the pliers head is worn out by arranging a rotating joint, a protrusion, an insert block, a pliers head, a slot, a card slot, a slide groove, a spring and a card block, thereby reducing the replacement cost. At the same time, different types of pliers heads can be replaced during use to meet the needs of different oral dental treatments, thereby improving the applicability. When the pliers head is worn out and needs to be replaced, the sliding card block is pressed to enter the inside of the slide groove, and the pliers head can be removed from the rotating joint. When replacing a new or different type of pliers head, the sliding card block is pressed to enter the inside of the slide groove, the spring is compressed, and then the insert block is inserted into the slot, and the sliding card block slides into the inside of the card slot under the elastic force of the spring, thereby fixing the pliers head on the rotating joint.
[0013] 2. The utility model achieves the effect of facilitating the disassembly of the two rotating joints by arranging an internally threaded tube, an externally threaded rod, a limit key and a slotted groove, thereby facilitating the cleaning and disinfection of the junction of the two rotating joints. The externally threaded rod and the internally threaded tube are connected by threads and become the rotating axes of the two rotating joints inside the rotating hole, while the limit key serves to limit the two rotating joints to prevent the rotating joints from slipping off the externally threaded rod and the internally threaded tube. When it is necessary to clean and disinfect the junction of the two rotating joints, a slotted screwdriver is inserted into the slotted groove, and the externally threaded rod and the internally threaded tube are rotated in opposite directions at the same time, so that the externally threaded rod and the internally threaded tube can be removed from the rotating hole, and the two rotating joints can be separated.

DETAILED DESCRIPTION
[0022] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0023] like Figure 1-Figure 6 As shown, the utility model proposes an oral orthodontic pliers, including a pliers head 1, a rotating joint 3, a pliers handle 5 and a fixed ring 8. A rotating hole 4 is provided on the front surface of the rotating joint 3 at the axial position, and an external threaded rod 18 and an internal threaded tube 19 are movably inserted inside the rotating hole 4, and one end of the external threaded rod 18 is located inside the internal threaded tube 19, and limit keys 21 are provided on the rear surface of the internal threaded tube 19 and the front surface of the external threaded rod 18 near the edge position. The external threaded rod 18 and the internal threaded tube 19 are connected by threads, and become the rotating axis of rotation of the two rotating joints 3 inside the rotating hole 4, and the limit key 21 plays a role of limiting the two rotating joints 3 to prevent the rotating joint 3 from slipping off the external threaded rod 18 and the internal threaded tube 19.
[0024] A slotted groove 20 is provided at the axial position of the rear surface of the internal threaded tube 19 and the front surface of the external threaded rod 18. When the intersection of the two rotating joints 3 needs to be cleaned and disinfected, a slotted screwdriver is inserted into the slotted groove 20, and the external threaded rod 18 and the internal threaded tube 19 are rotated in opposite directions at the same time, so that the external threaded rod 18 and the internal threaded tube 19 can be removed from the rotating hole 4, and the two rotating joints 3 are separated. The lower surface of the rotating joint 3 is fixedly connected with the clamp handle 5, the upper surface of the rotating joint 3 is provided with a protrusion 2, and the upper surface of the protrusion 2 is provided with an insert block 13. The protrusion 2 and the insert block 13 are integrally processed with the rotating joint 3, and a slide groove 16 is provided on one side of the outer surface of the insert block 13. A spring 17 is fixedly connected inside the slide groove 16, and a sliding block 15 is fixedly connected to the end of the spring 17. A slot 12 is provided on the lower surface of the pliers head 1, and the insert block 13 is located inside the slot 12. A card slot 14 is provided on one side of the outer surface of the pliers head 1, and the sliding card block 15 is located inside the card slot 14.
[0025] A limit block 11 is fixedly installed on the side of the outer surface of the pliers head 1 away from the slot 14. The limit block 11 limits the two pliers heads 1 after they are closed to prevent the pliers heads 1 from being damaged due to excessive force. A silicone sleeve 10 is fixedly sleeved on the outer surface of the pliers handle 5. An arc-shaped groove 9 is arranged on the outer surface of the silicone sleeve 10. The silicone sleeve 10 can improve the comfort when holding the pliers handle 5. When the fingers enter the arc-shaped groove 9, it can play an anti-slip role when holding the pliers handle 5. An arc-shaped spring piece 6 is fixedly connected to the outer surface of the pliers handle 5 near the upper surface. The two arc-shaped spring pieces 6 on the two pliers handles 5 are in contact, and the pliers handle 5 and the pliers head 1 are automatically opened by the elastic force of the arc-shaped spring piece 6. A fixed groove 7 is arranged on the outer surface of the pliers handle 5 near the lower surface. When the orthodontic pliers are not in use, the fixing ring 8 is inserted into the two fixing grooves 7 to fix the two pliers handles 5 and the two pliers heads 1 to prevent the two pliers handles 5 and the two pliers heads 1 from rotating.
[0026] When the utility model is in use, when the pliers head 1 is worn and needs to be replaced, the sliding block 15 is pressed to enter the slide groove 16, and the pliers head 1 can be removed from the rotating joint 3. When replacing a new or different type of pliers head 1, the sliding block 15 is pressed to enter the slide groove 16, the spring 17 is compressed, and then the insert block 13 is inserted into the slot 12. The sliding block 15 slides into the slot 14 under the elastic force of the spring 17, and the pliers head 1 is fixed on the rotating joint 3.
[0027] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
