The secondary wiring loop (loop wire) obtaining manner generally includes the following two types: one method is that when wiring, the clamp part at the front end of the wire removing clamp is directly utilized to roughly press a wire into a ring shape according to the size of a corresponding screw; this approach has two drawbacks: on one hand, the wire stripper is made of thinner material, so that a pressing ring can be completed for a thin wire, and a thick wire is difficult to press; on the other hand, the size and shape of the wiring clamping ring obtained in the mode are dependent on the technical skill of an operator. For workers with unskilled technology, the problems that the shape of the compression ring is not standard, the deformation is serious, and the compression ring is too large or too small can occur. If the voltage is repeatedly pressed on a section of wire, the quality of the wire is reduced; if the wires are cut off due to disqualification and then pressed again, the wires are wasted. Especially for the integrated automation transformation project, because the original length of the prior old cable is limited, the problem of insufficient length of the lead wire is caused by multiple times of ring pressing and shearing. The second method is to use a conventional sharp-nose pliers pressure ring, the material of the sharp-nose pliers is thicker and heavier, and the conventional sharp-nose pliers pressure ring can be used for crimping a thick wire to form a wiring pressure ring, but the quality of the pressure ring also needs to depend on the skill level of workers.

Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be further described with reference to the accompanying drawings and specific embodiments, but the present invention is not limited thereto.
In a first embodiment, as shown in fig. 1, the present invention provides a pair of secondary wiring ring pressing pliers, which includes a left pliers body 100, a right pliers body 200 and a connecting portion 300, wherein the left pliers body 100 and the right pliers body 200 are connected by the connecting portion 300 to form a pair of openable pliers bodies that are bilaterally symmetrical;
the left clamp body 100 and the right clamp body 200 are correspondingly divided into a pressure ring segment 10, a line-pulling segment 20, a shearing segment 30, a connecting segment 40 and a handle 50 from top to bottom,
when the two pressure ring segments 10 are closed, six concentric cylinders are formed, and the diameters of the six cylinders are sequentially increased from top to bottom; the two wire stripping segments 20 are sequentially provided with three wire stripping holes 21 with different apertures from top to bottom by taking the diameter of the contact surface as the center; the contact surfaces of the two shearing sections 30 are correspondingly provided with cutting edges;
the two connecting sections 40 are connected through a connecting part 300; the two handles 50 can form the opening and closing of the pressure ring segment 10, the line segment 20 and the shearing segment 30 by the connecting part 300; a spring 51 is connected between the two handles 50, and the free state of the spring 51 enables the forceps bodies to be closed.
The secondary wiring pressing ring pliers can be formed by improving the existing sharp-nose pliers.
In the work of relay protection secondary wiring, the screws which are usually encountered are generally 3mm in diameter (secondary wiring in a terminal wire), 4mm in diameter (secondary wiring in a disconnecting link) and 6mm or 8mm in diameter (secondary wiring in a current transformer and a voltage transformer). The secondary wiring ring pressing pliers can be designed according to the diameter data of the screws of the four models. For example, the total length of the clamp body can be set to be 16.5 cm; the pressure ring section 10 is 3cm long, the ripping section 20 is 1.5cm long, the shearing section 30 is 1cm long, and the handle 50 is 11cm long.
The middle of the cutting section 30 is polished to be a sharp edge and can be used for cutting secondary lines.
The spring 51 has the effect that the clamp body can be automatically closed when the tool is not in use. When in use, the corresponding section can be opened by pressing the handle 50, and the use is convenient.
By way of example, as shown in fig. 1, the diameters of the six sections of cylinders are 2mm, 3mm, 4mm, 6mm, 8mm and 10mm from top to bottom. The diameter is selected for a corresponding screw size fit.
As shown in the figure 1, the height of the six sections of cylinders is 5mm as an example. The pressure ring segment 10 is now 3cm in total length.
Referring to fig. 1, for example, the area of the wire-pulling hole 21 is 1.5mm from top to bottom in sequence2、2.5mm2And 4mm2. Three types of wire-stripping circular holes are provided in the example, and the selection of the size of the wire-stripping circular holes is determined according to three types of secondary wires frequently encountered by secondary wiring.
Furthermore, a wire-pulling blade is arranged in the wire-pulling hole 21. The edge of the inner wall of the wire-pulling hole 21 is polished to be a sharp blade, so that the wire can be pulled. The different wire stripping holes 21 are suitable for stripping wires with different wire diameters. The inner diameter of the cutting edge needs to be smaller than the corresponding outer diameter of the lead and is adaptive to the skin thickness of the lead.
Still further, an anti-slip sheath is sleeved on the handle 50. The anti-slip sheath can ensure that the tool is safer and more comfortable to use.
Still further, as shown in fig. 2, the opposing contact surfaces of the two pressure ring segments 10 are configured as a mesh tooth clamping surface. The meshed teeth are adopted on the joint surfaces of the two pressure ring segments 10, so that the friction force of the contact surfaces can be increased, and the reliable and smooth clamping of the conducting wire is facilitated.
