Description

Technical Field

[0001] This application relates to the field of hand tools, and more particularly to pliers. Background Technology

[0002] Pliers are common hand tools in daily life, including wire cutters, diagonal pliers, wire cutters, and electrician's pliers. Each type of pliers has a different function, but they all have the same requirements for certain parameters, such as cutting force, effort reduction ratio, and safety. These parameters are usually marked on the packaging card, which is generally discarded after the first use, making it difficult for users to know the technical specifications of the pliers. Utility Model Content

[0003] This application provides a pair of pliers that offers good operational safety and convenience.

[0004] Specifically, this application provides a pair of pliers, including a first plier body, a second plier body, a first handle, and a second handle. The first plier body includes a first jaw, a first pivot portion, and a first plier handle. The second plier body includes a second jaw, a second pivot portion, and a second plier handle. The first pivot portion is rotatably mounted on the second pivot portion. The first handle is sleeved on the first plier handle, and the second handle is sleeved on the second plier handle. A jaw is formed between the first jaw and the second jaw. The first handle and the second handle are elastic. The first handle includes a first gripping area and a first transition area. The first transition area is located between the first gripping area and the first pivot portion. The first transition area has a first blocking surface and a first connecting surface. The first gripping area has a first gripping surface. The pliers include a parameter display area exposed on the first connecting surface and / or the first gripping surface. The parameter display area displays the force-saving ratio of the pliers. The first connecting surface is adjacent to the first pivot portion. The first blocking surface is connected to the first gripping surface and configured to prevent the hand gripping the first handle from moving towards the first pivot portion.

[0005] Furthermore, the first handle includes a first segment and a second segment, the second segment being surrounded by the first segment, and the second segment having a different color than the first segment, and the parameter display area being formed in the second segment.

[0006] Furthermore, the first and second sections are formed in one injection molding process.

[0007] Furthermore, the parameter display area is formed through a printing process.

[0008] Furthermore, the force-saving ratio is a percentage or fraction, and the formula for calculating the force-saving ratio is (570 - actual shearing force) / 570, where the actual shearing force is the shearing force when the pliers cut the workpiece.

[0009] Furthermore, the parameter display area is located on the first connection surface.

[0010] Furthermore, the first blocking surface gradually increases in size from the first gripping surface toward the first connecting surface.

[0011] In this application, the first blocking surface can prevent the user's hand from approaching the first pivot part, and the parameter display area makes it easy for the user to understand the parameters of the pliers so as to select the appropriate product. Attached Figure Description

[0018] Please combine Figures 1 to 3 This application provides a pair of pliers 100, including a first plier body 1, a second plier body 2, a first handle 3 and a second handle 4. The first plier body 1 includes a first plier head 11, a first pivot part 12 and a first plier handle 13. The second plier body 2 includes a second plier head 21, a second pivot part 22 and a second plier handle 23. The first pivot part 12 is rotatably mounted on the second pivot part 22. The first handle 3 is sleeved on the first plier handle 13 and the second handle is sleeved on the second plier handle 23. A jaw is formed between the first plier head 11 and the second plier head 21.

[0019] Optionally, the first clamp body 1 and the second clamp body 2 are typically made of steel, while the first handle 3 and the second handle 4 are made of soft rubber to improve grip comfort. The first handle 3 includes a first gripping area 31 and a first transition area 32. The first transition area 32 is located between the first gripping area 31 and the first pivot portion 12. The first transition area 32 is provided with a first blocking surface 321 and a first connecting surface 322. The first gripping area 31 has a first gripping surface 311. The clamps include a parameter display area 30 exposed on the first connecting surface 322 and / or the first gripping surface 311. The parameter display area at least displays the force-saving ratio of the clamps. The first connecting surface 322 is adjacent to the first pivot portion 12. The first blocking surface 321 is connected to the first gripping surface 311 and configured to prevent the hand gripping the first handle 3 from moving towards the first pivot portion 12, preventing the pivot structure from causing injury to the user's hand. Preferably, the first blocking surface 321 gradually increases in size from the first gripping surface 311 toward the first connecting surface 322, so that the first blocking surface 321 can fit against the web of the hand, improving the gripping experience.

[0020] The force-saving ratio is a parameter of the pliers, characterizing the degree to which the pliers save effort. Its calculation formula is: Force-saving ratio = (570 - Actual shearing force) / 570, where the actual shearing force is the shearing force exerted by the pliers when cutting the workpiece, and 570 (in N) is the theoretical maximum shearing force. Specifically, the force-saving ratio is a percentage (e.g., 30%, 60%, 90%) or a fraction (e.g., 1 / 3, 1 / 2, 1 / 4). Optionally, the parameter display area 30 can also display parameters such as the jaw size and insulation coefficient, allowing users to quickly understand the pliers' parameters for appropriate selection.

[0021] Preferably, the parameter display area 30 is located on the first connecting surface 322. Since the first blocking surface 321 has blocked the user's hand, the user can still directly observe the parameters in the parameter display area even when holding the handle, without having to change the grip posture to view them.

[0022] Optionally, the first handle 3 includes a first segment 3A and a second segment 3B, the second segment 3B being surrounded by the first segment 3A, and the color of the second segment 3B being different from the color of the first segment 3A. The parameter display area 30 is formed in the second segment 3A for easy observation. The first segment 3A and the second segment 3B are formed in one injection molding process (i.e., the mold is simultaneously injected with two colors of liquid material). In other words, the parameter display area 30 (or the second segment 3B) is directly formed by a mold, making it less prone to fading and disappearing due to wear, thus improving its lifespan, and the processing steps are also relatively simple. Of course, in other embodiments, the parameter display area 30 can also be formed by printing, such as screen printing.

[0023] Please combine Figure 4In another embodiment, the parameter display area 30 is disposed on the first grip surface 311. The first grip surface 311 has a larger area, which is beneficial for displaying more parameters, and the size of each parameter can also be enlarged, making it easier to observe. Optionally, the parameter display area 30 can be disposed at any position such as the top, middle, or bottom of the grip surface.

[0024] It is worth noting that the first handle 3 in this application can be either of the two handles. The figure is only for illustration and does not limit the first handle to the handle on the left. The structure of the other handle (i.e. the second handle 4) is roughly the same as that of the first handle. The other handle can be configured to have a parameter display area, or it can be configured not to.

[0025] In this application, the first blocking surface can prevent the user's hand from approaching the first pivot part, and the parameter display area makes it easy for the user to understand the parameters of the pliers so as to select the appropriate product.

[0026] The above description is merely a preferred embodiment of this application and is not intended to limit this application in any way. Although this application has disclosed the preferred embodiment as above, it is not intended to limit this application. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of this application. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this application without departing from the content of the technical solution of this application shall still fall within the scope of the technical solution of this application.
