Description

Technical Field

[0001] The utility model relates to the technical field of tool pliers, in particular to a pair of elbow pliers with high practicality. Background Art

[0002] Bent nose pliers, also known as bent-nose pliers, are primarily used for clamping parts in narrow or recessed workspaces. Their curved jaws provide greater operational flexibility and accessibility. Depending on the specifications, bent nose pliers may have insulated or non-insulated handles to accommodate different work requirements. They are highly versatile: the bent nose design makes them particularly suitable for use in narrow or recessed workspaces, such as automotive repair, electronic assembly, and other fields. Pliers in the prior art have relatively simple functions, and their handles are generally cylindrical, such as Figure 1 As shown, the pliers are easy to break away and slip after a long time of use, and are difficult to locate during binding, which is not very practical. In addition, the pliers in the prior art mainly function at the pliers tip, have a single function, and are less practical. Utility Model Content

[0003] The utility model aims to overcome at least one defect of the above-mentioned prior art and provide a high-practicability elbow pliers to achieve the purpose of simple and lightweight structure and high practicality.

[0004] The utility model provides a highly practical elbow pliers, comprising a first pliers body, a second pliers body and a torsion spring assembly, wherein the first pliers body comprises a first pliers head and a first handle, and the second pliers body comprises a second pliers head and a second handle; the first handle and the second handle are square columns, and a limiting column is provided on the top of the first handle and the second handle.

[0005] Furthermore, the connection surfaces between the limiting column and the first handle and the second handle are inclined surfaces.

[0006] Conventional pliers typically have cylindrical handles, which can easily slip and rotate after being fitted with a nested, or anti-slip, cover. Therefore, the curved pliers of the present invention offer greater hand-holding stability compared to conventional pliers. Furthermore, the first and second handles of the present invention are square pillars, which increase the contact area with the anti-slip cover and further prevent slipping through the application of glue. The first and second handles have a rectangular cross-section, with the upper and lower sides being longer than the left and right sides. This square pillar design prevents slipping and provides greater stability during operation. The present invention also features a stopper post, which protrudes from the gripping area of ​​the first and second handles and is integrally formed. When the anti-slip covers are applied to the first and second handles, the top of the cover fits against the stopper post, and glue is applied at the fitting location to secure the top of the cover. Furthermore, the connecting surface between the stopper post and the cover is an inclined surface, further increasing the contact area between the stopper post and the cover.

[0007] Furthermore, the first clamp head includes a first bending clamping section and a first linear clamping section; the second clamp head includes a second bending clamping section and a second linear clamping section; the inner sides of the first bending clamping section and the second bending clamping section are provided with serrations; when the torsion spring assembly is in a compressed state, the first bending clamping section and the second bending clamping section engage with each other to form an elbow section; the first linear clamping section and the second linear clamping section are clamped to form a linear section, and the angle between the elbow section and the linear section is α, where α is 145~165°.

[0008] Furthermore, the first linear clamping section includes one or more semicircular first through-holes; the second linear clamping section includes one or more semicircular second through-holes; in the clamped state, the first through-holes and the second through-holes form a circular clamping position. Furthermore, the circular clamping positions are provided in two groups, each with different diameters. More preferably, the present invention is designed with two groups of circular clamping positions, one large and one small, to accommodate wires of different diameters and can be used for wire stripping.

[0009] Furthermore, the first linear clamping section further includes a first blade, and the second linear clamping section includes a second blade. In the clamped state, the first blade and the second blade form a linear shearing position.

[0010] Furthermore, the first linear clamping section further includes a third through hole, and the second linear clamping section further includes a convex column. In the clamping state, the convex column is embedded in the third through hole to form a curved shearing position.

[0011] Furthermore, the tops of the first linear clamping segment and the second linear clamping segment are serrated and mesh with each other in the clamped state.

[0012] This utility model features three clamping methods on the linear section of the elbow pliers. The first and second linear clamping sections have serrated tops that mesh to achieve clamping, seamlessly connecting with the elbow section. From the tip toward the handle, circular, curved, and straight shearing positions are designed, allowing for flexible use in different scenarios and providing high practicality.

[0013] More preferably, the included angle between the elbow section and the linear section is 150-160°.

[0014] Furthermore, the torsion spring assembly includes a central female nut, a torsion spring member, and a central male nut; the torsion spring member is arranged between the first pliers head and the second pliers head, and the central female nut and the central male nut are used to tighten the first pliers head and the second pliers head to achieve a rotational connection. The central female nut is inserted from the first pliers head, and the central male nut is inserted from the second pliers head, and the two are nested and tightened. The first pliers head and the second pliers head are each provided with a groove position so that the torsion spring member can be installed between the two. The two ends of the torsion spring member are respectively embedded in the groove positions of the first pliers head and the second pliers head. When the torsion spring member is in a relaxed state, the first pliers head and the second pliers head are in a separated state. By clamping the first handle and the second handle, the torsion spring member is gradually compressed to achieve the engagement of the first pliers head and the second pliers head.

[0015] Furthermore, the first and second handles are provided with a plurality of slots. The slot design can ensure the stability of the handles while reducing the overall weight, making them more practical and lightweight. The slot design also facilitates the application of glue during the fixing process.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The elbow pliers of the present invention avoid the problem of easy slipping after the anti-slip cover is installed by designing the handle as a square column. Through the design of the square column, the limit column and the inclined surface of the limit column, the contact area between the inner surface and the top surface of the anti-slip cover and the first handle and the second handle can be increased, thereby improving the stability of operation.

[0018] The highly practical elbow pliers of this utility model are designed to have an angle of 145 to 165 degrees between the elbow section and the linear section, in accordance with actual application requirements, making them more practical and convenient. Furthermore, the pliers head of this utility model is multifunctional. The provision of the toothed linear section facilitates daily clamping. The design of the first and second through holes allows for stripping of wires of different diameters. The design of the first and second blades also allows for shearing.
