[0039] The protection plate 25 is detachably connected to the top of the needle seat 2 by screws; the above arrangement facilitates the disassembly and assembly of the protection plate 25 and the needle seat 2.

[0040] In the online test quick wiring tool described in this embodiment, the top of the test probe 22 is provided with an external thread; the needle groove 21 is provided with a first nut 23 that matches the top of the test probe 22; the power connection wire 3 is provided with a first conductive sheet; after the first conductive sheet contacts the test probe 22, the first nut 23 is threadedly connected with the test probe 22 to lock the first conductive sheet with the test probe 22. Specifically, through the above arrangement, when the first conductive sheet is inserted into the test probe 22, the test probe 22 is locked with the first conductive sheet through the first nut 23, which can ensure that the power connection wire 3 and the test probe 22 are electrically conductive.

[0041] In the embodiment of the invention, the housing 1 is made of metal; a metal column 4 is provided on the housing 1; and the metal column 4 is provided with an external thread.

[0042] The online test quick wiring tool also includes a grounding wire and a second nut 41; the grounding wire is provided with a second conductive sheet; after the second conductive sheet contacts the metal column 4, the second nut 41 is threadedly connected with the metal column 4 to lock the second conductive sheet with the metal column 4. Specifically, through the above arrangement, when the second conductive sheet is inserted into the metal column 4, the metal column 4 and the second conductive sheet are locked by the second nut 41, which can ensure that the grounding wire is electrically conductive with the metal column 4, thereby grounding the standard machine.

[0043] In the online test quick wiring tool described in this embodiment, a limiting plate 11 is provided at the bottom of the housing 1. Through the above arrangement, the housing 1 can be positioned with the air switch 9.

[0044] The embodiment of the present invention is an online test quick wiring fixture, wherein the fixture comprises a base 6 arranged on a shell 1, a hinged seat 61 arranged on the top of the base 6, an extension plate 62 arranged on the bottom of the base 6 and a sleeve 63 arranged on the extension plate 62; the fixture also comprises a shift block, an arc-shaped member 71 and a lifting column 72; the lifting column 72 is lifted and lowered in the sleeve 63; the bottom of the lifting column 72 is connected to the L-shaped connecting piece 24; the top of the lifting column 72 is hinged to the bottom of the arc-shaped member 71; the shift block comprises a hinged portion 81, a handle portion 82 and a connecting portion 83 arranged between the hinged portion 81 and the handle portion 82; the hinged portion 81 is hinged to the hinged seat 61; the top of the arc-shaped member 71 is hinged to the connecting portion 83; the end of the handle portion 82 is provided with an insulating rubber sleeve.
