Description

Technical Field

[0001] The utility model belongs to the technical field of orthodontic instruments, in particular to an orthodontic pliers. Background Art

[0002] Orthodontic instruments are composed of orthodontic pliers, tweezers and positioners. Orthodontic pliers, as an important medical device for teeth correction, mainly include a pliers handle and a pliers head. Generally, the pliers handle controls the movement of the pliers head through a pin shaft. When the orthodontic pliers are working, the pliers handle is pressed to make the pliers heads close to each other to deform the corresponding positions of the braces. The patient wears the adjusted braces to twist the teeth to be orthodontized to a normal position to achieve the purpose of tooth correction. When the orthodontic pliers are adjusting the braces, the pliers head is prone to a certain degree of wear. The worn pliers head cannot accurately adjust the braces, affecting the correction of the teeth. In addition, the price of orthodontic pliers is relatively expensive, which leads to excessively high costs of orthodontic pliers. Utility Model Content

[0003] The technical problem to be solved by the utility model is that when orthodontic pliers are used to adjust braces, the pliers heads are easily worn, and the worn pliers heads cannot accurately adjust the braces, which affects the correction of teeth. At present, orthodontic pliers are relatively expensive in the market, resulting in excessively high costs for replacing orthodontic pliers.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A pair of orthodontic pliers comprises a pliers head and two symmetrically arranged pliers handles, the pliers head comprises a left jaw and a right jaw, an inverted "L"-shaped fixing block is arranged on the opposite surface of the left jaw and near the top thereof, a groove matching the fixing block is arranged inside the right jaw at the position of the fixing block, the left jaw and the right jaw are rotatably hinged, a connecting block is arranged on the end of the left jaw and the right jaw away from the fixing block, arc-shaped sliding grooves are arranged on the two opposite sides of the connecting block, an installation cavity matching the connecting block is arranged on the end of the pliers handle close to the pliers head, a fixing assembly is arranged between the pliers handle and the connecting block, and the pliers head and the pliers handle are connected and fixed by the fixing assembly.

[0006] Furthermore, the fixing component also includes a rotating column and a rotating block. The rotating column passes through one side of the installation cavity and its upper surface is fixedly connected to the bottom surface of the rotating block. The outer surface below the rotating column is fixedly connected to a connecting rod. The other end of the connecting rod is fixedly connected to an arc piece that matches the slide groove. A slide groove that is slidably connected to the arc piece is provided inside the installation cavity and near the top of it.

[0007] Furthermore, the grip of the pliers handle is provided with anti-slip grooves.

[0008] Working principle and beneficial effects:

[0009] The utility model has a detachable connection between a pliers head and a pliers handle, the pliers head comprises a left pliers clamp and a right pliers clamp which are rotatably hinged, and a connecting block on the pliers head is clamped with an arc piece inside a mounting cavity so that the pliers head is connected to the pliers handle, and the rotating block is rotated so that the arc piece is slidably connected between a slide groove on the connecting block and a slide groove inside the mounting cavity so that the pliers head and the pliers handle are fixedly connected; the rotating block is rotated again so that the arc piece slides out of the slide groove, which is convenient for disassembly and replacement of the pliers head.

[0010] The utility model can match a plurality of pliers heads with a pair of pliers handles, which is simple and quick to operate, saves equipment cost, is easy to carry, can effectively improve the convenience of use for users, and can also alleviate the situation that the orthodontic pliers are expensive and have high subsequent maintenance costs; the anti-slip pattern 13 arranged on the pliers handle 2 can increase the friction between the palm and the pliers handle 2 to prevent the orthodontic pliers from sliding when in use, and the inverted "L"-shaped fixing block can facilitate the cutting of the groove for the barb on the braces, which can effectively avoid derailment.
