Description

Technical Field

[0001] This utility model relates to the field of needle-nose pliers technology, specifically a multi-functional needle-nose pliers for after-sales service of switch cabinets. Background Technology

[0002] Needle-nose pliers are a common type of clamp tool. They are mainly used to cut thin single-strand and multi-strand wires, as well as to bend single-strand wire joints and strip plastic insulation. They can be used in relatively confined workspaces. Those without cutting edges can only perform clamping work, while those with cutting edges can cut small parts. They are one of the most commonly used tools for electricians, especially for assembling and repairing internal wiring equipment.

[0003] When used in switchgear, it is often necessary to bundle multiple wires into wire lugs. Typically, needle-nose pliers are used to strip the insulation from the cables, then multiple copper wires are twisted together, and the twisted wire is placed into the wire lug. Then, pliers are used to press the copper wire firmly into the lug. This wire bundling process requires two tools, which is cumbersome and reduces work efficiency. Furthermore, the shape of the needle-nose pliers results in insufficient force on the wire lug, making it difficult to ensure proper clamping and affecting wiring stability. Therefore, this multi-functional needle-nose pliers for switchgear after-sales service was designed. By folding the first and second upper jaws, the pliers are made into a vise shape, increasing the clamping force on the wire lug and ensuring wiring stability. Utility Model Content

[0028] Please see Figure 1 and Figure 3 This utility model provides a technical solution: a multi-functional needle-nose pliers for after-sales service of switchgear, including a left plier head and a right plier head, the left plier head and the right plier head rotate around the same axis, the lower end of the left plier head is connected to a first insulating handle 3, the lower end of the right plier head is connected to a second insulating handle 4, the left plier head includes a second upper plier head 2 and a second lower plier head 204, a second hinge 202 is provided on the outer surface of the second upper plier head 2 and the second lower plier head 204, the second upper plier head 2 and the second lower plier head 204 rotate around the pivot of the second hinge 202, a second locking device is provided on the second upper plier head 2 and the second lower plier head 204 to lock the second upper plier head 2 and the second lower plier head 204, ensuring the normal use of the needle-nose pliers, preventing the second upper plier head 2 from folding outward during wire twisting, the second hinge 202 makes the second upper plier head 2 fold outward, reducing the length of the left plier head, and changing the needle-nose pliers into the shape of pliers;

[0029] The right pliers head includes a first upper pliers head 1 and a first lower pliers head 104. A first hinge 102 is provided on the outer surface of the first upper pliers head 1 and the first lower pliers head 104. The first upper pliers head 1 and the first lower pliers head 104 rotate around the pivot of the first hinge 102. A first locking device is provided on the first upper pliers head 1 and the first lower pliers head 104 to lock the first upper pliers head 1 and the first lower pliers head 104. Through the first hinge 102, the first upper pliers head 1 can be folded on the first lower pliers head 104, thereby reducing the length of the right pliers head, transforming the needle-nose pliers into a vise, increasing the pressure on the wire lugs, making the connection between the copper wire and the wire lugs stable, and improving the stability of the wiring.

[0030] like Figure 2 As shown, the second locking device includes a second engaging plate 206 at the lower part of the second upper jaw 2 and a second bent plate 205 at the upper part of the second lower jaw 204.
