[0046] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0047] Example 1:

[0048] like Figures 1-9 As shown, a high-voltage generator for cable fault testing includes a high-voltage generator body 1 with a storage slot, and two first conductors 9 are installed inside the storage slot of the high-voltage generator body 1.

[0049] The limit recovery mechanism is located inside the storage tank of the high voltage generator body 1. The limit recovery mechanism is used to recover the first wire 9.

A second clamping arm 5 is fixedly mounted on the rotating shaft 16. A torsion spring is mounted on the rotating shaft 16. The torsion spring is used to connect the first clamping arm 4 and the second clamping arm 5.

[0051] A protective mechanism is located at the bottom of the first clamping arm 4 and is fixedly connected to the first clamping arm 4. The protective mechanism is used to connect the first wire 9 to the first clamping arm 4.

[0052] The fixing mechanism is located on the side of the first clamping arm 4 and is fixedly connected with the first clamping arm 4, and is used for limiting the rotation of the second clamping arm 5.

[0053] The prompting mechanism is located on the side of the first clamping arm 4 and is fixedly connected with the first clamping arm 4, and is used for issuing a sound prompt of the clamping status of the first clamping arm 4 and the second clamping arm 5.

[0054] The limiting recovery mechanism comprises a first mounting box 2 and a second mounting box 7, and the first mounting box 2 and the second mounting box 7 are located inside the storage groove of the high-voltage generator body 1 and are fixedly connected with the high-voltage generator body 1.

[0055] The first mounting box 2 and the second mounting box 7 are fixedly connected with a mounting pipe 10, the mounting pipe 10 is fixedly connected with a limiting ring inside, a second extrusion rod 20 is slidingly connected inside the mounting pipe 10, one end of the second extrusion rod 20 is fixedly connected with a limiting frame 8, the limiting frame 8 is used for limiting the first lead wire 9, the other end of the second extrusion rod 20 is fixedly connected with a second spring 21, and the second spring 21 is connected with the limiting ring.

[0058] The first rotating rod 22 and the second rotating rod 25 are fixedly connected with a belt pulley 24, and the two belt pulleys 24 are connected through a connecting belt 11.

[0059] When the first clamping arm 4 and the second clamping arm 5 need to be used;

[0060] The first rotating rod 22 can be rotated first, the first rotating rod 22 drives the second magnetic block 23 to rotate, the second magnetic block 23 acts on the fourth magnetic block, so that the fourth magnetic block and the second magnetic block 23 are magnetically attracted, and the second extrusion rod 20 can be effectively returned to the inside of the mounting pipe 10, so that the limiting of the first lead wire 9 is cancelled;

[0061] The rotation of the first rotating rod 22 also drives the second rotating rod 25 to rotate through the belt pulley 24 and the connecting belt 11, the second rotating rod 25 also drives the fourth magnetic block to rotate, so that the fourth magnetic block can return to the inside of the mounting pipe 10 under the action of the magnetic force, so that the first lead wire 9 is relaxed and can be easily pulled out, thereby facilitating use;

[0062] When not in use, the first lead wire 9 can be restored to the original state by rotating, so that the first lead wire 9 can be stored and protected.

[0063] Embodiment 2:

[0064] As Figures 1-9 shown, in other parts are the same as example 1, the difference between this embodiment and example 1 lies in: the protection mechanism comprises the first insulation box 6, the first insulation box 6 is fixedly connected with the first clamping arm 4;

[0065] The first insulation box 6 is fixedly connected with the first conductive block 27 and the second conductive block 29, the first conductive block 27 is connected with the first clamping arm 4, and the second conductive block 29 is connected with the first wire 9;

[0066] The opposite surface of the first conductive block 27 and the second conductive block 29 is fixedly connected with the conductive sheet 28.

[0067] The protection mechanism further comprises a limiting tube 26, and the limiting tube 26 is fixedly connected with the first insulation box 6;

[0068] The limiting tube 26 is fixedly connected with a limiting box 30 inside, the limiting box 30 is slidably connected with a sliding block 31 inside, the sliding block 31 is connected with the limiting box 30 through a plurality of third springs 32, the sliding block 31 is fixedly connected with a sliding rod 33, and both ends of the sliding rod 33 extend to the outside of the limiting tube 26;

[0069] The sliding block 31 is provided with a track groove 34, the limiting box 30 is fixedly connected with a mounting plate 36, the mounting plate 36 is rotatably installed with a rotating plate 35, the rotating plate 35 is rotatably installed with a rotating column, and the rotating column is located in the track groove 34.

[0070] The fixing mechanism comprises a fixing box 12, and the fixing box 12 is fixedly installed on the first clamping arm 4;

[0071] The fixing box 12 is fixedly installed with an electromagnet 19 inside, two third wires are installed on the electromagnet 19, the two third wires are connected with the first conductive block 27 and the second conductive block 29 respectively, a first magnetic block 18 is arranged on the right side of the electromagnet 19, the first magnetic block 18 is slidably connected with the mounting box, a first extrusion rod 14 is fixedly connected with the first magnetic block 18, the first extrusion rod 14 penetrates through the fixing box 12 and is slidably connected with the fixing box 12, a first spring 13 is sleeved on the first extrusion rod 14, and both ends of the first spring 13 are connected with the fixing box 12 and the first magnetic block 18 respectively;

[0072] The rotating shaft 16 is fixedly connected with a fixing ring 17, a plurality of limiting grooves 15 are formed in the fixing ring 17, and the limiting grooves 15 are inserted with the first extrusion rod 14.

[0073] When the first clamping arm 4 and the second clamping arm 5 are clamped onto the object to be clamped, the sliding rod 33 can be pressed. The sliding rod 33 will drive the slider 31 to move. Due to the action of the third spring 32 and the rotating plate 35, the slider 31 and the sliding rod 33 can be moved a certain distance and then limited to a fixed position. In this way, the sliding rod 33 can move away from the conductive sheet 28 and will not squeeze the conductive sheet 28. In this way, the two conductive sheets 28 will stick together and can be used to conduct electricity.

[0074] Since the first conductive block 27 and the second conductive block 29 are energized, the third wire will transmit power to the electromagnet 19, thereby making the electromagnet 19 magnetic. The electromagnet 19 will then act on the first magnetic block 18, causing the first magnetic block 18 to move away from the electromagnet 19. As a result, the first magnetic block 18 will drive the first pressing rod 14 to approach the fixing ring 17 and insert into the limiting groove 15 on the fixing ring 17. This can effectively position the second clamping arm 5 and effectively prevent the first clamping arm 4 and the second clamping arm 5 from falling off.

[0075] Example 3:

[0076] like Figures 1-9 As shown, while all other parts are the same as in Embodiment 1, the difference between this embodiment and Embodiment 1 is that: the prompting mechanism includes a second insulating box 40, which is fixedly mounted on the first clamping arm 4;

[0077] Inside the second insulating box 40, two third magnetic blocks 45 are fixedly connected. A wire frame 44 is set between the two third magnetic blocks 45. Copper rings 43 are fixedly connected to both ends of the bottom of the wire frame 44. A brush 42 is set on the opposite side of the two copper rings 43. The brush 42 is fixedly connected to the second insulating box 40. A second wire 41 is fixedly installed on the brush 42. The two second wires 41 are respectively connected to the first conductive block 27 and the second conductive block 29.

[0078] The notification mechanism also includes a compression box 38, which is fixedly connected to the second insulation box 40. A reciprocating screw 46 is rotatably mounted on the compression box 38 and is fixedly connected to the wire frame 44.

[0079] A piston plate 39 is threaded onto the reciprocating lead screw 46. The piston plate 39 is slidably connected to the extrusion box 38. An air inlet pipe 37 is fixedly connected to one side of the extrusion box 38, and an air outlet pipe is fixedly installed on the other side of the air inlet pipe 37. One-way valves are installed on both the air inlet pipe 37 and the air outlet pipe, and an air horn 47 is installed on the air outlet pipe.

[0080] The first conductive block 27 and the second conductive block 29 are conductive, so that the second wire 41 will deliver power to the two brushes 42, and then into the wire frame 44, the wire frame 44 after being energized and the third magnet, will rotate, so that the wire frame 44 will drive the reciprocating lead screw 46 to rotate, the reciprocating lead screw 46 will drive the piston plate 39 to move up and down constantly, so that the piston plate 39 can effectively extract and exhaust air, and the exhaust air will enter the air horn 47, so that the air horn 47 will make a sound, thereby effectively playing a prompting role, according to the sound, whether the power is on can be judged.

[0081] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application.
