the trigger mechanism 11 performs an adsorption action with the second magnet 116 through the electromagnet 114, so as to fix the sliding rod 115, meanwhile, the magnetic force of the electromagnet 114 can be adjusted through the magnitude of the current, so that the adsorption force between the electromagnet 114 and the second magnet 116 can be adjusted to be slightly smaller than the sum of the tensile force which can be borne by the flexible graphite grounding wire 12 and the upward tilting force of the clamping plate 101 under the action of the second spring 104 (the tensile force borne by the flexible graphite grounding wire 12 means that the internal structure of the flexible graphite grounding wire is not damaged after being pulled under the action of the force, and the flexible graphite grounding wire 12 can be normally used), so that when the flexible graphite grounding wire 12 is subjected to a large tensile force, the rotating shaft 91 is driven to rotate, so that the arc-shaped plate 94 on the rotating wheel 93 has an upward force effect on the clamping plate 101, when the tensile force is larger than the adsorption force between the electromagnet 114 and the second magnet 116, the sliding rod 115 is jacked, the limitation of the rotating wheel 93 is released, and at this time, the flexible graphite grounding wire 12 can be pulled, so that the flexible graphite grounding wire 12 is prevented from being broken or damaged due to overlarge pulling force, and after the external pulling force is reduced or disappears, the sliding rod 115 gradually recovers to the initial state under the action of the adsorption force between the electromagnet 114 and the second magnet 116, and the limiting is continuously kept.
According to the invention, two flexible graphite grounding wires 12 are respectively penetrated into the protective box 1 through the threading pipes 6, firstly wound on the winding wheels 96 of the winding mechanism 9 and then sequentially passed through the pulleys 83 at the bottoms of the first elastic telescopic rod 81 and the second elastic telescopic rod 82, and when the flexible graphite grounding wires 12 are pulled by tensile force, the first elastic telescopic rod 81 and the second elastic telescopic rod 82 can be pulled down and extended, so that excessive tensile force on the electrically connected end parts of the flexible graphite grounding wires 12 is avoided;
then, the flexible graphite grounding wires 12 are fixedly connected in the connecting mechanism 7, specifically, the flexible graphite grounding wires 12 are firstly inserted into the sliding groove 705 through the sliding block 123 and then pushed inwards, at this time, the clamping rods 7062 on the elastic clamping pieces 706 are pulled upwards, the conductive heads 121 are inserted into the slots 703, meanwhile, the magnets III 122 adsorb the magnets I704 for preliminary fixing and positioning, then the clamping rods 7062 are loosened, and the clamping rods 7062 penetrate through the connecting blocks 701 under the pulling of the springs I7063 and are clamped into the clamping grooves 124 to be fixed, so that the electrical connection and the fixation of the two flexible graphite grounding wires 12 are realized;
when the flexible graphite grounding wire 12 is pulled from one side of the connecting mechanism 7, the flexible graphite grounding wire can be pulled, and after the flexible graphite grounding wire is pulled, the rotating shaft 91 is driven to rotate, so that the rotating wheel 93 rotates, the arc-shaped plate 94 on the rotating wheel is pressed downwards to the clamping plate 101, so that the second spring 104 is compressed, and the rotating can rotate;
on the contrary, when the tensile force applied to the flexible graphite grounding wire 12 is small, the clamping plate 101 is limited to be fixed and cannot be pulled under the limitation of the trigger mechanism 11;
when the flexible graphite grounding wire is subjected to large pulling force, the upward acting force of the second spring 104 on the pulling force combined clamping plate 101 is greater than the attraction force of the electromagnet 114 and the second magnet 116 in the triggering mechanism 11, the triggering mechanism 11 is triggered, so that contact limitation is realized, the flexible graphite grounding wire can be pulled, the flexible graphite grounding wire 12 is prevented from being damaged due to the fact that the external pulling force is too large, and after the external pulling force disappears, the flexible graphite grounding wire is recovered to the initial state and can be recycled.
