DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that although the description of these embodiments is used to help understand the present invention, it does not constitute a limitation of the present invention.

[0025] The specific structural and functional details disclosed herein are only used to describe the exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments set forth herein.

[0026] According to a first aspect of the present disclosure, a multifunctional elastic clamp pliers suitable for pipelines is provided. Figures 1 to 3 The specific implementation of the multifunctional elastic clamp pliers suitable for pipelines is shown.

[0027] See also Figures 1 to 3As shown, the multifunctional elastic clamp pliers suitable for pipelines include: a handle 1, which is provided in two pieces, the two handles 1 are cross-arranged and a central axis 2 is provided at the intersection of the two handles, so that the clamp handles can be rotatably connected; a clamp head 3 made of metal material, which is provided in two pieces and fixedly connected to the handles 1; among the two clamp heads 3, one of the clamp heads 3 is provided with a limiting column 31, and the other clamp head 3 is provided with a limiting groove 32 matched with the limiting column 31; wherein each clamp head 3 is provided with a first notch 33 in the shape of an arc, and the first notches 33 of the two clamp heads 3 are arranged opposite to each other; a blade 4, which is fixedly connected to the first notch 33 of one of the clamp heads 3; and a spring 5, the two ends of the spring 5 are respectively connected to the two handles 1, and the spring 5 is located inside the intersection area formed by the two handles 1.

[0028] Through the above technical solution, the handle 1 can be formed into a lever structure with the central axis 2 as the rotation center. After applying pressure at the middle position, the spring 5 pops open, so that the operator can operate with one hand. When it is necessary to connect pipelines such as oil pipes or water pipes, the end of the pipeline can be cut flat or cut off by the water pipe cutting function of the blade 4 on the multifunctional elastic clamp pliers, and then the handle 1 is held inward and closed, thereby squeezing the elastic clamp to increase the diameter of the elastic clamp, and then the pipeline is inserted into the elastic clamp and connected to the equipment. In this way, the work is completed.

[0029] During the entire operation, the multifunctional elastic clamp pliers can be used to cut the pipe flat, cut off, and expand the elastic clamp. The worker holds the multifunctional elastic clamp pliers in one hand and other accessories (such as pipes or other auxiliary parts) in the other hand, thereby completing the operation quickly and effectively. The multifunctional elastic clamp pliers integrate the functions of vise and scissors into one, and there is no need to replace other tools during the operation, thereby optimizing the operation steps. In addition, the elastic clamp is limited in position during the process, and there will be no flying and injuring people, reducing safety hazards.

[0030] In the present disclosure, the pliers head 3 provided with the blade 4 is also provided with a second notch 34, and the blade 4 extends to the area of ​​the second notch 34; and the radius of the second notch 34 is smaller than the radius of the first notch 33. With this design, different operations can be performed on the elastic clamp, which is beneficial to enriching the functions of the multifunctional elastic clamp pliers and improving the applicability to clamps of different types or specifications.

[0031] In an embodiment provided in the present disclosure, a conical guide column 6 is provided on the inner wall of the handle 1, and the small diameter end of the guide column 6 points to the other handle 1; the end face of the guide column 6 is configured as a curved surface; when the handle 1 is unfolded, the spring 5 is detached from the guide column 6. Such a design can position and guide the spring 5, thereby helping to smoothly put the spring 5 on the guide column 6, or to smoothly detach the spring 5 from the guide column 6.

[0032] In an embodiment provided in the present disclosure, the multifunctional elastic clamp pliers also include a screw 7, and the blade 4 is fastened to the pliers head 3 by the screw 7. Such a design can facilitate the installation and fixation of the blade 4, so that different blades 4 can be replaced in time, and has good flexibility and practicality.

[0033] In an embodiment provided by the present disclosure, a protruding boss 8 is provided on the pliers head 3 without the blade 4, and a part of the boss 8 overlaps the blade 4. In this way, the elastic clamp can be operated in different areas and with different contents, thereby achieving different operation purposes.

[0034] One of the pliers 3 is provided with a first clamping groove 35, which is arranged between the limiting column 31 and the first notch 33; the other pliers 3 is provided with a second clamping groove 36 in a staggered manner, which is arranged between the limiting groove 32 and the first notch 33. This design can grasp the elastic clamp, so as to stabilize the elastic clamp.

[0035] In an embodiment provided by the present disclosure, the multifunctional elastic clamp pliers further include a safety buckle 9, wherein a positioning hole for installing the safety buckle 9 is provided on one handle 1; a positioning groove 10 adapted to the safety buckle 9 is provided on the other handle 1, and the end of the handle 1 is flat. In this way, when the handles 1 are closed, the safety buckle 9 can be rotated and sleeved on the other handle 1. Since this section is set in a flat shape, the safety buckle 9 can be easily inserted and removed.

[0036] In addition, based on the design of the spring 5, it will generate a restoring force after being compressed, so that the two handles 1 are opened in opposite directions. With the help of this elastic force, the handles 1 can be opened and the safety buckle 9 can be tightened, so that the safety buckle 9 can be reliably constrained in the positioning groove 10.

[0037] In this disclosure, see Figure 1 As shown, the handle 1 is provided with a plurality of ridges 11 extending along the length direction thereof, so that the friction of the hand during operation can be increased, making it easier for the operator to hold the handle 1 for stable operation.

[0038] Specifically, the ridges 11 are configured as rubber ridges arranged at intervals, which can increase the friction with the hand and is beneficial to stable operation.

[0039] Of course, the ridge 11 can also be configured as a plastic protrusion, so that the ridge 11 and the handle 1 can be integrally formed, which is convenient for production.

[0040] It should be noted that the utility model is not limited to the above optional implementations, and anyone can derive other various forms of products under the inspiration of the utility model. The above specific implementations should not be understood as limiting the scope of protection of the utility model. The scope of protection of the utility model shall be based on the definition in the claims, and the description can be used to interpret the claims.
