Detailed ways

As shown in FIG. 1 , the grounding wire clip disclosed in this embodiment includes a hook body 1 , a tongue piece 2 , a buckle 3 , a pull cord 4 , a rotating cord 5 , an elastic member 6 and a force regulating assembly 7 .

The hook main body 1 is an integral piece, including a hook segment 11 and a straight line segment 12; the hook segment 11 is an n-type hook, the top of the blind end is provided with a stand 13 for connecting the rotating rope 5, and a grounding copper wire 8 is connected to the outside. The two ends of the open side are provided with mounting holes for mounting the tongue 2; the straight section 12 is connected to the lower end of one side. The tongue piece 2 is a bending elastic piece, the bottom end of the tongue piece is a hinge joint, the tongue piece is sleeved at the installation hole with its hinge joint, and is glued by a pin shaft, and a pair of tongue pieces are arranged in an X-shape relative to each other.

The buckle 3 is arranged at the bottom end of the straight section through the force regulating assembly 7 . As shown in FIG. 2 , the force regulating assembly 7 includes a ring sleeve 71 and a pair of adjusting bolts 72 . The ring sleeve is provided with a pair of radial threaded holes penetrating the wall thickness, and the adjusting bolts are connected in the threaded holes; the buckle 3 is a The round tube has a pair of through holes on its wall. During installation, insert the clip 3 into the annular sleeve 71 and screw the adjusting bolt into the through holes to complete the assembly. After the installation is completed, the drawstring 4 is passed through the buckle and then extended into the hook main body, and the drawstring is respectively connected to the top of the pair of tongues after bypassing the pin shaft in the hook main body. Tie the rotating rope 5 between the stand and the ring sleeve. And an elastic member 6 is placed on the drawstring jacket of the hook main body 1 to improve the use effect. As shown in FIG. 3, the elastic member 6 includes a T-shaped tube 61 and a spring 62. The T-shaped tube includes a horizontal section and a vertical section. A spring is arranged in the vertical section. The vertical section of the tube is passed through and connected to the tongue.
