[0024] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine with the embodiments to detail the present invention.

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part rather than all of the embodiments of the present utility model. The description of at least one exemplary embodiment below is actually only illustrative and in no way restricts the present utility model and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0026] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments of the present utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0027] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present utility model. At the same time, it should be clear that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, further discussion thereof is not required in subsequent drawings.

[0028] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" are usually based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus should not be construed as limiting the scope of protection of the present utility model: the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0029] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. can be used here to describe the spatial positional relationship of a device or feature shown in the figure with other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations during use or operation in addition to the orientation described in the figure for the device. For example, if the device in the attached drawing is inverted, a device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations are made for the spatial relative descriptions used here.

[0030] In addition, it should be noted that using words such as "first", "second" etc. to define components is only for the convenience of differentiating the corresponding components. Without additional declaration, the above words have no special meaning, and thus cannot be understood as a limitation to the protection scope of the present utility model.

[0031] The present utility model provides a technical solution: a sealing rubber ring cutting pliers, as Figure 1-8 shown, comprising an upper base 1 and a lower base 2, characterized in that an upper jaw 4 is provided on the lower surface of the upper base 1, a lower jaw 5 is provided on the upper surface of the lower base 2, circular holes are respectively provided on both sides of the upper base 1 and the lower base 2, and two round rods 3 respectively pass through the circular holes on both sides and are fixedly connected to the lower base 2 and slidably connected to the upper base 1, and the upper base 1 slides up and down along the round rods 3 to drive the upper jaw 4 to move.

[0032] Five lower jaws 5 are provided on the lower base 2, and the inner wall of the upper part of the lower jaw 5 is set to be arc-shaped. Due to the arc-shaped design of the lower jaw 5, the rubber ring can be firmly clamped between the lower jaw 5 and the upper jaw 4. The arc diameters of the arc-shaped inner walls of the lower jaws 5 are different, and different specifications of the lower jaws 5 can fix and cut rubber rings with diameters of φ16, 14, 12, 10, and 8 millimeters. The upper jaw is designed as a blade and is very sharp.

[0033] The using process of the present utility model is as follows:

[0034] First, select a suitable lower jaw 5 according to the diameter of the rubber ring, and fix one end of the rubber ring in the arc-shaped inner wall of the lower jaw 5;

[0035] Second, the upper base 1 slides downward through the left and right two round rods 3 as slideways to drive the upper jaw 4 to move downward to cut the rubber ring;

[0036] Thirdly, the other end of the rubber ring is placed into the arc-shaped inner wall fixed on the lower jaw 5 on the other side of the lower jaw 5. The upper jaw 4 moves downward to cut the rubber ring, and the other end of the mating part can be cut out.

[0037] Fourthly, sealant is applied to the two cut surfaces. After they are fitted together, a firmly connected rubber ring is formed.

[0038] It is very strong and durable and can better adapt to places with very high sealing requirements.

[0039] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
