In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As the background art shows, the overhead conductors of the power transmission lines in China are generally steel-cored aluminum strands, and the length of each steel-cored aluminum strand is about 1500 to 2000 meters. Generally, the outer layer of the steel-cored aluminum strand is an aluminum wire strand that is electrically conductive, while the inner layer is a steel strand that is subjected to the operating tension of the entire wire. When the power transmission line is moved and modified and repaired, the aluminum conductor wound and coated on the periphery of the steel core needs to be stripped before the conductor is connected, and the steel core is exposed to prepare for crimping. Specifically, when the wire crimping machine is used for crimping, the steel strand winding strand needs to be connected by the crimping machine, then the outer aluminum wire winding strand needs to be connected by the crimping machine, and the outer aluminum wire winding strand needs to be stripped off before the steel strand winding strand is connected, so that the connection work can be performed. The quality of aluminum stranded wire stripping directly influences the connection quality of the wire, the connection is easily influenced if the port for cutting the aluminum stranded wire is irregular, even the steel core is damaged in the stripping process, and the stress strength after wiring is influenced, so that the requirements on the wire stripping operation are better operation rapidness and convenience, the tool is light and convenient, and simultaneously, the steel stranded wire winding strand is not damaged in the wire stripping process. When the compression joint wire stripping operation is performed on the steel-cored aluminum strand, the traditional wire stripping operation method is manual wire stripping or wire stripping operation performed by using a large wire stripping tool.
The inventor notices that when a manual wire stripping method is adopted, a rotating blade is usually used for continuously and manually rotating the steel-cored aluminum strand to separate the aluminum wires wound and coated on the periphery one by one, so that the steel core cannot be accidentally injured, the efficiency is low, the physical strength is consumed, and particularly when the wire is a large-section wire, the requirement on the physical strength of an individual is high; when a large-scale wire stripping tool is used for stripping wires, the wire stripping precision is not high, so that the steel core is easily damaged by mistake, meanwhile, the wire stripping tool is large in size and not easy to carry, and when a tool bit needs to be replaced, the tool bit is not convenient to disassemble and assemble.
In order to solve this problem, the present inventors have studied and found that a wire cutting and stripping device can be designed to be compact and portable. Particularly, the wire cutting and stripping device is designed as a handheld device, and the tool bit is detachably connected to the handle, so that a user can conveniently hold the device to perform crimping and stripping operations, and meanwhile, the tool bit can be replaced by other types of tool bits at any time, and other operations on wires can be performed.
Based on the above consideration, in order to solve the problem that the existing crimping wire-stripping method and wire-stripping tool cannot simultaneously consider the wire-stripping precision and the wire-stripping efficiency, the inventor designs a wire-cutting wire-stripping device which has high wire-stripping precision, is easy to carry and can rapidly replace a tool bit, the inspiration of the design is derived from the appearance design of a pistol, the wire-cutting wire-stripping device is designed into the appearance shape similar to a pistol, a host computer is arranged at the tail part of the wire-cutting wire-stripping device, a fixed tool bit and a movable tool bit are detachably arranged at the head part of the wire-cutting wire-stripping device, the fixed tool bit and the movable tool bit are detachably connected with the host computer through a joint, and when crimping wire-stripping is carried out, high-precision wire stripping can be realized by moving the movable tool bit relative to the fixed tool bit.
The wire cutting and stripping device disclosed by the embodiment of the application can be used for cutting and stripping steel-cored aluminum stranded wires, and can also be used for cutting and stripping wires of other types, so that the wire cutting and stripping device disclosed by the application can be used for reducing the labor intensity of operators and improving the stripping efficiency, the wire stripping precision of the wire cutting and stripping device disclosed by the application can be high, the wire cutting and stripping device is easy to carry, and the cutter head can be quickly replaced.
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

The inventor has found in the study that although the above structure is convenient for fixing the wire 20, the wire 20 must pass through the fixing tool 300 from one side to the other side to be inserted into the holding hole 301, and when the length of the wire 20 is several kilometers, the insertion is inconvenient because the length of the wire 20 is too long.
In order to solve the above problem, the fixed cutter 300 may be designed to be capable of being opened or closed. Specifically, as shown in fig. 2, the fixed cutting head 300 includes a fixed portion 310 and a movable portion 320, the fixed portion 310 has three connecting ends, namely a first connecting end 311, a second connecting end 312 and a third connecting end 313, in a preferred embodiment, a connecting line of the three connecting ends is an isosceles triangle, a length of a connecting line of the first connecting end 311 and the second connecting end 312 is equal to a length of a connecting line of the first connecting end 311 and the third connecting end 313, and the connecting line of the second connecting end 312 and the third connecting end 313 is perpendicular to a central axis of the joint 200, wherein the first connecting end 311 is detachably fixed to an outer wall of the joint 200 at an end away from the main body 100, and the second connecting end 312 and the third connecting end 313 are used for connecting with the movable portion 320. The end of the fixing portion 310 away from the connector 200 is formed with a holding groove 314. In one embodiment, the shape of the clamping groove 314 is preferably a concave arc in a direction from the movable portion 320 toward the fixed portion 310 for clamping the cylindrical wire 20.
Corresponding to the holding groove 314 of the fixing portion 310, as shown in fig. 3, a first cutting edge 321 is formed at one end of the movable portion 320 near the fixing portion 310. In the first embodiment, the first cutting edge 321 is also a concave arc in the direction from the fixed portion 310 to the movable portion 320, and the first cutting edge 321 and the holding groove 314 of the fixed portion 310 may be symmetrical to each other in shape, and the arc radii of the first cutting edge 321 and the holding groove 314 may be equal to each other or may not be symmetrical to each other, and the arc radii of the first cutting edge and the holding groove are different. The first cutting edge 321 and the clamping groove 314 together define the clamping hole 301. The movable portion 320 has two connecting ends, namely a fourth connecting end 322 and a fifth connecting end 323, the fourth connecting end 322 is rotatably hinged to the second connecting end 312 of the fixed portion 310, so that the movable portion 320 can rotate relative to the fixed portion 310, and meanwhile, the fifth connecting end 323 can also be connected to the third connecting end 313 of the fixed portion 310 through a latch, so that the movable portion 320 and the fixed portion 310 are in an open or closed state. When the fifth connection end 323 of the movable part 320 is not connected with the third connection end 313 of the fixed end, the movable part 320 and the fixed part 310 are in an open state; when the fifth connecting end 323 of the movable portion 320 is connected to the third connecting end 313 of the fixed end by the latch, the movable portion 320 and the fixed portion 310 are in a closed state, and at this time, the first cutting edge 321 of the movable portion 320 and the clamping groove 314 of the fixed portion 310 define a clamping hole 301 similar to a kidney shape.
The connection form between the second connection end 312 of the fixed portion 310 and the fourth connection end 322 of the movable portion 320 is not limited to hinge connection, and may be pin connection, hinge connection or hinge connection; the connection form between the third connection end 313 of the fixed part 310 and the fifth connection end 323 of the movable part 320 is not limited to the plug connection, and may be a snap connection, which is not limited herein.
In some embodiments, the movable blade 400 has a shape similar to that of the fixing part 310 of the fixed blade 300, and one end of the movable blade 400 is inserted into a through hole of the housing 210 of the joint 200 and detachably connected to the piston of the joint 200. The movable blade 400 is provided with a second cutting edge 410 at one end away from the joint 200, the shape of the second cutting edge 410 is completely symmetrical to the shape of the first cutting edge 321 provided on the movable portion 320 of the fixed blade 300, when the movable portion 320 of the fixed blade 300 and the fixed portion 310 of the fixed blade 300 are in a closed state, the second cutting edge 410 is located at one side of the movable blade 400 facing the first cutting edge 321, and the first cutting edge 321 and the second cutting edge 410 form a cutting gap together. In the first embodiment, the shape of the second cutting edge 410 is also preferably a concave-shaped circular arc that is the same as the shape of the first cutting edge 321 in the direction from the movable portion 320 of the fixed blade 300 toward the fixed portion 310.
In this way, as shown in fig. 1, the movable blade 400 is located behind the fixed portion 310 of the fixed blade 300 when viewed from the front, and the driving element can drive the movable blade 400 to move toward or away from the movable portion 320 of the fixed blade 300, so that the second cutting edge 410 of the movable blade 400 can be close to or away from the first cutting edge 321 of the fixed blade 300, and the second cutting edge 410 of the movable blade 400 and the first cutting edge 321 of the fixed blade 300 are located on the same plane.

At this time, the cutting gap formed by the first cutting edge 321 and the second cutting edge 410 is already much smaller than the outer diameter of the wire 20, so that the wire 20 can be cut. When the reset button 114 is pressed or the stroke of the movable blade 400 is waited to be finished, the movable blade 400 is reset to the original position in the direction away from the movable portion 320 of the fixed blade 300, the power source 120 is pressed again to drive the button 113, the second cutting edge 410 approaches in the direction approaching to the first cutting edge 321 of the fixed blade 300 again, and the cutting operation on the wire 20 is finished again when the movable blade 400 moves to the maximum stroke.

The difference is that in this embodiment, a semicircular first core holding groove 3211 is further formed at the middle position of the first cutting edge 321, and a semicircular second core holding groove 411 is further formed at the middle position of the second cutting edge 410.
Referring to fig. 1 and 5, when the wire 20 is inserted into and clamped in the clamping hole 301 of the fixed blade 300, the power source 120 is pressed to drive the button 113, and the second cutting edge 410 of the movable blade 400 approaches in a direction approaching the first cutting edge 321 of the fixed blade 300 until the movable blade 400 moves to a maximum stroke. At this time, as shown in fig. 5, the first core holding groove 3211 of the first cutting blade 321 and the second core holding groove 411 of the second cutting blade 410 together form a circular core holding site 101, the diameter of the core holding site 101 is equal to the diameter of the steel core 210 in the middle of the wire 20, and the cutting gap formed by the remaining portion of the first cutting blade 321 excluding the first core holding groove 3211 and the remaining portion of the second cutting blade 410 excluding the second core holding groove 411 is also much smaller than the outer diameter of the wire 20.
