referring to fig. 1-5, the present invention provides a technical solution: a rotary type grounding wire clamp comprises a wire clamp main body 1, wherein a screw-nut pair 2 is fixedly arranged at the lower end inside the wire clamp main body 1, a screw rod 3 is arranged in the screw thread inside the screw-nut pair 2, a connecting sleeve 4 is fixedly arranged at the lower end of the screw rod 3, an insulating rod 5 is arranged at the lower end of the connecting sleeve 4, a connecting rod seat 6 is rotatably arranged at the upper end of the screw rod 3, a connecting terminal fixing seat 7 is fixedly arranged at the lower end of the right side wall of the wire clamp main body 1, an incomplete driving gear 8 is rotatably arranged at the right end inside the wire clamp main body 1, a through hole is formed in the side wall of the incomplete driving gear 8, the upper end of the connecting rod seat 6 is rotatably connected with the through hole through a shaft pin, an incomplete driven gear 9 is rotatably arranged at the left end of the incomplete driving gear 8, a movable clamping jaw 15 is fixedly arranged on the lower side wall of the incomplete driven gear 9, the left side wall of the incomplete driven gear 9 is fixedly provided with a wire guide swing arm 10, the right end of the movable clamping jaw 15 is provided with a neodymium iron boron magnet 11, the left end of the connecting rod seat 6 is provided with a ferromagnetic column 12, and the inside of the wire clamp body 1 is fixedly provided with an initial position limiting pin 14 at the upper end of the incomplete driving gear 8.
The upper end of the screw rod 3 is rotatably connected with the connecting rod seat 6 through a cylindrical pin 13.
The position of the fixed clamping jaw of the wire clamp body 1 adopts a V-shaped structure.
The working principle is as follows:
when the operation is prepared (as shown in fig. 2), the insulation rod 5 needs to be rotated anticlockwise to drive the incomplete driving gear 8 to rotate to the initial position limiting pin 14 (namely, after the incomplete driving gear 8 start point limiting groove is attached to the initial position limiting pin 14, the incomplete driving gear cannot rotate anticlockwise), the wire clamp is in an initial reset state when a wire is to be hung, the incomplete driving gear 8 and the incomplete driven gear 9 on the lower clamping jaw are in a non-meshed state, and the two devices are not influenced by each other temporarily. The movable clamping jaw 15 is influenced by the gravity center of the structure of the movable clamping jaw, is always in a state shown in fig. 2 when no external force acts on the movable clamping jaw, and meanwhile, a square neodymium iron boron magnet 11 is additionally arranged at the rear side end of the movable clamping jaw 15, a ferromagnetic column 12 is arranged on the connecting rod seat 6, and under the influence of magnetic force, the neodymium iron boron magnet 11 on the movable clamping jaw 15 is tightly attached to the ferromagnetic column 12 on the wire clamp body 1. Therefore, the movable clamping jaw 15 ensures the initial state position by using the attraction force of the magnet;
(as shown in fig. 3), when the wire touches the wire guide swing arm, the wire is collided, the neodymium iron boron magnet 11 at the rear end of the wire clamping jaw is separated from the ferromagnetic column 12, the wire guide swing arm rotates clockwise, when the wire clamping jaw rotates to the point that the head tooth on the incomplete driven gear 9 enters the two teeth of the incomplete driving gear 8 to intersect, the wire clamping jaw stops rotating, at the moment, the two gears are in a meshing state, the head tooth on the incomplete driven gear 9 is prevented from interfering with the tooth top of the driven wheel before the head tooth on the incomplete driven gear 9 on the lower clamping seat enters the meshing, the driven wheel is guaranteed to stop at a preset initial meshing position when meshing each time, the tooth top height of the head tooth on the incomplete driven gear 9 is correspondingly reduced, namely, the tooth top height coefficient is designed to be lower than a standard value;
(as shown in fig. 4), an operator only needs to hold the insulating rod 5 to slightly rotate clockwise by a certain angle to drive the front end screw rod 3 to rotate, the screw rod 3 moves downwards to drive the connecting rod seat 6 to move downwards, the connecting rod seat 6 moves downwards to drive the incomplete driving gear 8 to rotate anticlockwise, and the incomplete driving gear 8 is meshed with the incomplete driven gear 9 to rotate, so that the wire clamp clamps the wire. The whole installation process is quick and easy, and an operator can clamp the lead by slightly rotating the insulating rod 5 for less than two circles, so that the grounding purpose is achieved;
after the grounding operation is finished (as shown in fig. 5), an operator only needs to rotate the insulating rod 5 anticlockwise to drive the incomplete driving gear 8 to rotate to the initial position limiting pin (namely, the left side wall of the limiting groove of the incomplete driving gear 8, and at the moment, the insulating rod 5 cannot rotate anticlockwise), then the insulating rod 5 is pushed out towards the upper part of the lead, the wire clamp is separated from the lead, and the dismounting operation of the grounding wire is finished.
