Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a pair of braces punching pliers. Background Art

[0002] The depth of the holes punched by the existing braces punching pliers depends on the size of the pliers head, which cannot meet the actual use requirements; when punching braces in actual use, the predetermined hole size cannot be reached at one time, and multiple cutting operations will be performed, which increases the complexity and tediousness of the operation. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the clamp heads of the existing punching pliers are fixed and cannot be adjusted, and the punching depth and width cannot be adjusted, which increases the complexity of operation.

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

[0005] A braces punching pliers comprises a first pliers head and a second pliers head, wherein a guide rail groove with a "cross" cross section is provided at symmetrical positions where the front and back sides of the first pliers head and the second pliers head are close to each other, and a sliding block adapted thereto is slidably connected in the guide rail groove;

[0006] Arc-shaped cutting knives are fixedly connected in sequence to the opposite sides of the sliding blocks respectively located on the first clamp head and the second clamp head.

[0007] Furthermore, a through hole is provided on one side of the sliders located on the first clamp head and the second clamp head respectively, and a connecting sleeve is fixedly connected to the position of the through hole on the side, and the inner surface and the outer surface of the connecting sleeve are both provided with threads;

[0008] The cutting knife is fixed by a nut threaded on the outer surface of the connecting sleeve;

[0009] The inner surface of the connecting sleeve is threadedly connected with a locking screw.

[0010] Working principle and beneficial effects: By adjusting the relative position of the slip ring and the guide groove, the distance between the cutting knife and the first clamp head and the second clamp head can be changed, so as to facilitate the punching and changing the punching size, so as to realize the operation of adjusting the punching size according to the needs of the operator.

[0015] The present invention can be better understood according to the following embodiments.

[0016] The structures, proportions, sizes, etc. illustrated in the drawings of the specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effect and purpose that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "front", "back", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.

[0017] like Figure 1 As shown,

[0018] Example

[0019] A braces punching pliers comprises a first pliers head 1 and a second pliers head 2. A guide groove 3 with a "cross"-shaped cross section is provided at symmetrical positions where the front and back sides of the first pliers head 1 and the second pliers head 2 are close to each other. A slider 4 adapted thereto is slidably connected in the guide groove 3. An arc-shaped cutting knife 5 is fixedly connected to the opposite sides of the sliders 4 respectively located on the first pliers head 1 and the second pliers head 2 in sequence. By adjusting the relative position of the slip ring 4 and the guide groove 3, the distance between the cutting knife 5 and the first pliers head 1 and the second pliers head 2 can be changed to facilitate punching and changing the size of the holes. A through hole is provided on the opposite sides of the sliders 4 respectively located on the first pliers head 1 and the second pliers head 2. A connecting sleeve 6 is fixedly connected to the side located at the position of the through hole. The inner and outer surfaces of the connecting sleeve 6 are both provided with threads. The cutting knife 5 is fixed by a nut screwed on the outer surface of the connecting sleeve 6, and the connecting sleeve 6 is fixed to the cutting knife 5. Before installing the cutting knife 5, a gasket is first put on the outer surface of the sleeve 6, and then the nut is installed. Adding the gasket can change the distance between the two ends of the cutting knife 5 to change the width of the hole. The inner surface of the connecting sleeve 6 is threadedly connected with a locking screw 7 to facilitate adjusting the relative position of the slider 4 and the guide groove 3, and changing the distance between the cutting knife 5 and the pliers head. Compared with the existing hole-opening pliers on the market, it better fits the curvature of the braces tooth surface.
