[0040] In order to further understand the content of the present application, the present application will be described in detail in combination with the drawings and examples.

[0041] As Figures 1-2 shown, a foldable hand pliers includes a handle 100 and a head 200. A metal arm 110 is placed in the handle 100, and the metal arm 110 extends from the handle 100 at one end to form a connecting end 111. The tail of the head 200 is hinged to the connecting end 111. The head 200 is provided with a protruding part 300, which is located on the rotating path of the connecting end 111, limiting the rotating angle of the handle 100 in the first direction 310. The first direction 310 is the direction of the handle 100 approaching each other. The side wall of the head 200 limits the rotating angle of the handle 100 in the second direction 320. The second direction 320 is the direction of the handle 100 moving away from each other. The folding action of the handle 100 can be realized by hinging the tail of the head 200 to the handle 100. In order not to affect the normal use of the hand pliers, the protruding part 300 is arranged on the head 200, which can limit the rotation of the handle 100 in the first direction 310. When the hand pliers is needed to work, the handle 100 of the hand pliers is moved towards each other, and when the handle 100 meets the protruding part 300 of the head 200, the protruding part 300 of the head 200 is pushed to move, so that the head 200 clamps the object. When folding is needed, only the handle 100 needs to be rotated in the second direction 320, and when the handle 100 contacts the side wall of the head 200, the handle 100 is limited to continue to rotate and is attached to the head 200, so as to realize the folding of the handle 100 and reduce the length of the hand pliers.

The first cutting part 233 has different circular cutting edges, which is convenient for cutting cables of different diameters, and the arc cutting edge of the second cutting part 234 can be used as scissors to cut articles.

[0045] As shown in the figure, Figure 2 As shown in the figure, the second functional area 240 has a protrusion 241 and a groove that are engaged with each other. The mutually engaged protrusion 241 and groove not only have a positioning effect, but also have a clamping effect. The protrusion 241 includes a positioning block 2411 and a clamping block, the end surface of the positioning block 2411 is an outward convex arc surface, and the corresponding positioning groove 2412 is adapted in shape to the shape of the positioning block 2411. The top surface of the clamping block 2421 is an inward concave arc surface, and the corresponding clamping groove 2422 is adapted in shape to the shape of the clamping block 2421. The positioning block 2411 has a positioning effect, and when the forcep is under stress, the front end of the positioning block 2411 is semicircular and engaged in the corresponding slot, which ensures that the clamping block accurately clamps the article and avoids mispositioning of the clamping block.

[0046] As shown in the figure, Figure 1 And Figure 4As shown, the inner side wall of the handle 100 is provided with a notch 140, and the electroscope 120 is clamped in the notch 140. The electroscope 120 is clamped on the inner side of the handle 100, and when the outer side of the handle 100 is forced, the electroscope 120 will not be loose and dislocated. The metal end of the electroscope 120 is in electrical contact with the metal arm 110 through the spring 130. The metal end of the electroscope 120 is in contact with the metal arm 110 through the spring 130, so that the electroscope arm can display whether the tongs head 200 is electrified without being taken out, so that the hand tongs can play a warning role when contacting the electric wire, reminding the operator to pay attention to avoid electric shock.
