Detailed Description
As shown in fig. 1, the ground clamp disclosed in this embodiment includes a hook body 1, a tongue 2, a buckle 3, a pull rope 4, a rotation rope 5, an elastic member 6, and a force adjusting assembly 7.
The hook main body 1 is an integral piece and comprises a hook section 11 and a straight section 12; the hook section 11 is an n-shaped hook, the top of the blind end of the hook section is provided with a vertical seat 13 for connecting the rotating rope 5, the outside of the hook section is connected with a grounding copper wire 8, and two ends of the opening side of the hook section are provided with mounting holes for mounting the tongue piece 2; the straight section 12 is connected below one side end. The tongue piece 2 is the shell fragment of bending, and the bottom of tongue piece is the articulated joint, and the tongue piece uses its articulated joint cover in mounting hole department, splices through the round pin axle, and a pair of tongue piece relative arrangement is the X type.
Buckle 3 sets up in the bottom of straightway through transferring power subassembly 7. As shown in fig. 2, the force adjusting assembly 7 includes an annular sleeve 71 and a pair of adjusting bolts 72, the annular sleeve is provided with a pair of radial threaded holes penetrating through the wall thickness, and the adjusting bolts are connected in the threaded holes; the buckle 3 is a round pipe, a pair of through holes are formed in the pipe wall of the round pipe, and the buckle 3 is inserted into the circular ring sleeve 71 during installation and is screwed into the through holes through the adjusting bolts to complete assembly.
