When the grounding wire clamp is used specifically, if the grounding wire clamp adopts a structure (shown in figures 1-12) to hook a wire, the wire enters from a wire clamp opening between the guide swing arm 15 and the lower clamping jaw 16, when the wire enters the wire clamp opening, the wire is firstly contacted with the guide swing arm 15, the guide swing arm 15 rotates clockwise around the lower clamping jaw hinge shaft 20 after being pushed by the wire, at the moment, because the acting force of the lower clamping jaw torsion spring 11 is smaller than the suction force of the neodymium iron boron magnet 32 and the ferromagnetic column 31, the lower clamping jaw 16 is always kept in a static state, the clockwise rotation amplitude of the guide swing arm 15 is increased along with the increase of the pushing acting force of the wire, the opening and closing degree of the guide swing arm 15 relative to the wire clamping opening between the lower clamping jaws 16 is obviously increased, therefore, the clamping requirements of wires with different wire diameters can be met, the guide swing arm 15 rotates, and the guide swing arm angle limiting column 29 moves in the lower clamping jaw limiting groove 28, when the angle limiting column 29 of the guide swing arm touches the right side wall of the lower clamping jaw limiting groove 28, the lower clamping jaw 16 starts to bear thrust, when the lower clamping jaw 16 drives the neodymium iron boron magnet 32 and the ferromagnetic column 31 to be separated from a suction state, the lower clamping jaw torsion spring 11 is separated from the limit and starts to reset, under the action of the lower clamping jaw torsion spring 11, the lower clamping jaw 16 rotates clockwise, the guide swing arm 15 synchronously rotates anticlockwise to quickly clamp a lead, when the lead moves upwards and touches the top end of the upper clamping jaw 30, the upward moving freedom degree is limited, the guide swing arm 15 and the lower clamping jaw 16 stop rotating, and therefore preliminary clamping of the lead is completed; if the grounding wire clamp adopts the structure (figure 13) to hang a wire, the wire enters from a wire clamp opening between the guide arm 21 and the lower clamping jaw 16, when the wire enters the wire clamp opening, the wire is firstly contacted with the guide arm 21, the guide arm 21 rotates clockwise around the lower clamping jaw hinge shaft 20 after receiving the thrust of the wire, at the moment, the lower clamping jaw 16 is always kept in a static state due to the clamping limiting action of the spring ball plunger 33, the spring ball plunger 33 is separated from the clamping state with the hook-shaped wire clamp body 1 along with the increase of the thrusting acting force of the wire, the lower clamping jaw 16 is quickly close to the wire under the action of the lower clamping jaw torsion spring 11, and the lower clamping jaw 16 and the upper clamping jaw 30 preliminarily clamp the wire; when the primary clamping is completed, the first tooth on the incomplete driven gear 23 just enters the intersection between two teeth of the incomplete driving gear 22, so that the incomplete driven gear 23 and the incomplete driving gear 22 are in a meshing state (the bulge of the cam 25 just enters the meshing groove of the non-circular belt meshing sheave 24, so that the cam 25 and the non-circular belt meshing sheave 24 are in a meshing state), at the time, the incomplete driving gear 22 (the non-circular belt meshing sheave 24) only needs to rotate a certain angle anticlockwise, namely the incomplete driving gear 22 (the cam 25) drives the lower clamping jaw 16 to move towards the direction of a lead, so as to further clamp the lead, an operator only needs to clockwise slightly rotate the insulated operating rod 2, so that the insulated operating rod 2 drives the lead screw connector 3 to rotate, the lead screw connector 3 drives the clamping lead screw 4 to rotate, the clamping lead screw 4 drives the lead screw connecting rod 12 to move downwards under the driving of the hook-shaped wire clamp thread female socket 9, the screw rod connecting rod 12 drives the screw rod connecting pin 13 to move downwards and enables the screw rod connecting pin 13 to slide in the chute 19, the screw rod connecting pin 13 drives the incomplete driving gear 22 (the noncircular belt meshing sheave 24) to rotate anticlockwise by a certain angle, so that the incomplete driving gear 22 (the noncircular belt meshing sheave 24) is meshed with the incomplete driven gear 23 (the cam 25), the incomplete driving gear 22 (the noncircular belt meshing sheave 24) drives the incomplete driven gear 23 (the cam 25) to rotate clockwise by a certain angle, the incomplete driven gear 23 (the cam 25) drives the lower clamping jaw 16 to rotate clockwise by a certain angle, the lower clamping jaw 16 gradually clamps and fixes a lead, at the moment, the insulating operating rod 2 cannot rotate clockwise any more, the work of clamping the lead is finished, the operation is fast and easy, and an operator can clamp the lead by only slightly rotating the insulating operating rod 2, the purpose of grounding is achieved. After the grounding operation is finished, an operator only needs to rotate the insulating operating rod 2 anticlockwise, the insulating operating rod 2 drives the screw rod connector 3 to rotate, the screw rod connector 3 drives the clamping screw rod 4 to rotate, the clamping screw rod 4 drives the screw rod connecting rod 12 to move upwards under the driving of the hook-shaped wire clamp thread female seat 9, the screw rod connecting rod 12 drives the screw rod connecting pin 13 to move and enable the screw rod connecting pin 13 to slide in the sliding groove 19, the screw rod connecting pin 13 drives the incomplete driving gear 22 (the non-circular belt meshing grooved pulley 24) to rotate clockwise for a certain angle, the initial position limiting pin 27 is attached to the left side wall of the driving meshing wheel start point limiting groove 26, the driving gear 22 (the non-circular belt meshing grooved pulley) and the incomplete driven gear 23 (the cam 25) are in a non-meshing state, the lower clamping jaw 16 is influenced by the gravity center of the structure of the lower clamping jaw, and is in a natural sagging state when no external force acts on the lower clamping jaw, the insulated operating rod 2 is pushed out towards the upper part of the wire, the wire clamp is separated from the wire, and then the dismounting operation of the grounding wire is completed, if the grounding wire clamp adopts the structure (shown in a figure 1-12), under the influence of magnetic force, the neodymium iron boron magnet 32 on the lower clamping jaw 16 is tightly attached to the ferromagnetic column 31, the initial state position of the lower clamping jaw 16 can be ensured by utilizing the suction force of the neodymium iron boron magnet 32 and the ferromagnetic column 31, so that the next preparation can be made for hanging the wire, if the grounding wire clamp adopts the structure (shown in a figure 13), the lower clamping jaw 16 is manually pushed, the spring ball plunger 33 is re-clamped with the hook-shaped wire clamp main body, the lower clamping jaw torsion spring 11 is twisted, and therefore the preparation can be made for hanging the wire next time.
