  "abstract": "A press cutting tool is disclosed. The press cutting tool includes a first and second plier, a first and second connecting rod, an opening, a pressing block, and a cutting block. The first and second connecting rods are connected to the second plier. The opening is used for placing a connection head. The pressing block is connected to the first connecting rod for clamping housing. The cutting block is connected to the second connecting rod for cutting the connection line; wherein the pressing block and the cutting block slide separately, and an initial distance from the pressing block to the opening is greater than an initial distance from the cutting block to the opening. After the first and second plier are pressed, the pressing block slides first to clamp and press the housing, and then the cutting block slides to cut the connection line.",
  "claims": [
    "1. A press cutting tool, used for cutting a connection head, the connection head comprising a connection line and a housing, the press cutting tool comprising: a first plier; a second plier, which is pivotally connected to the first plier through a first pivoting portion; a first connecting rod, which is connected to the second plier; a second connecting rod, which is connected to the second plier; an opening, located on the first plier, for placing the connection head, the opening having a first axis; a pressing block, which is located on a first side of the opening and connected to the first connecting rod, for clamping the housing; and a cutting block, which is located on a second side of the opening and connected to the second connecting rod, for cutting the connection line; wherein the pressing block and the cutting block slide separately along the first axis, and an initial distance from the pressing block to an end of the opening is greater than an initial distance from the cutting block to the end of the opening; wherein after the first plier and the second plier are pressed, the first connecting rod is used to make the pressing block slide to clamp and press the housing, and then the second connecting rod is used to slide the cutting block to cut the connection line.",
    "2. The press cutting tool as claimed in claim 1, wherein the first connecting rod comprising a second pivoting portion and a third pivoting portion, and the second connecting rod comprising a fourth pivoting portion and a fifth pivoting portion; wherein the first connecting rod is pivotally connected to the second plier by the second pivoting portion, and pivotally connected to the pressing block by the third pivoting portion; the second connecting rod is pivotally connected to the second plier by the fourth pivoting portion, and pivotally connected to the cutting block by the fifth pivoting portion.",
    "3. The press cutting tool as claimed in claim 2, wherein the first pivoting portion is at one end of the first plier.",
    "4. The press cutting tool as claimed in claim 3, wherein the distance between the second pivoting portion and the first pivoting portion is greater than the distance between the fourth pivoting portion and the first pivoting portion.",
    "5. The press cutting tool as claimed in claim 4, wherein the length of the first connecting rod is greater than the length of the second connecting rod.",
    "6. The press cutting tool as claimed in claim 5, wherein the first pivoting portion is located in a middle of the first plier.",
    "7. The press cutting tool as claimed in claim 6, wherein the distance between the second pivoting portion and the first pivoting portion is less than the distance between the fourth pivoting portion and the first pivoting portion.",
    "8. The press cutting tool as claimed in claim 7, wherein the second connecting rod is curve shaped.",
    "9. The press cutting tool as claimed in claim 2, wherein the first plier further comprising a first sliding hole and a second sliding hole, wherein after the first plier and the second plier are pressed, the third pivoting portion slides within the first sliding hole, and the fourth pivoting portion slides within the second sliding hole.",
    "10. The press cutting tool as claimed in claim 9, wherein the second sliding hole is a curved sliding hole, and after the first plier and the second plier are pressed, the second connecting rod is rotated by sliding the fourth pivoting portion within the second sliding hole.",
    "11. The press cutting tool as claimed in claim 10, wherein after the first plier and the second plier are pressed to cause the pressing block to slide, the fourth pivoting portion pushes the second connecting rod, so as to slide the cutting block."

  "description_excerpt": "The present invention relates to a press cutting tool, particularly to a press cutting tool which can make a connection head difficult to shake.\n\nNowadays, many different kinds of press cutting tools have been developed to install different sizes of connectors or ports. Hereafter, please first refer to FIG. 1 for an external view of a connection head of the prior art.\n\nIn the prior art, a connection head C with a specification of EZ-RJ45™ has been developed. Such connection head C has a simple one-piece design, and thus a technical staff can easily slide the connection line C 2 into the housing C 1, then pull it out from the front of the housing C 1, and finally cut off the connection line C 2 that goes out of the housing C 1. Therefore, it is easy to visually confirm the wiring layout of the connection line C 2 before pressing the housing C 1.\n\nThe method of operating the connection head C can be shown in FIGS. 2A-2C. FIGS. 2A-2C are schematic diagrams showing the operation of the press cutting tool of a first embodiment of the prior art.\n\nA press cutting tool 90 a of a first embodiment of the prior art includes a first plier 91 a, a second plier 92 a, a crimping section 93 a, a connecting rod 94 a, a first pivot joint 95 a, a second pivot joint 96 a, and a third pivot joint 97 a. The first plier 91 includes an opening 911, and the crimping section 93 a is located next to the opening 911. Also, the first plier 91 is pivotally connected to the second plier 92 a by the first pivot joint 95 a at the end.",
