Fig. 1 is a main TV structure sketch map of the present invention; Fig. 2 is the vertical view of Fig. 1; Fig. 3 is the A-A cutaway view of Fig. 1; Fig. 4 is the B-B cutaway view of Fig. 1.
Label among the figure: 1 pincers seat, 11 kidney slots, 12 locking nuts, 2 springs, 3 jacket seats, 31 flanks, 4 adjusting screw(rod)s, 5 connecting rods, 6 clamp, 7 adjusting rods, 8 shed sticks, 9 intermediate plates.
Below pass through the specific embodiment, and combine accompanying drawing that the present invention is described further.
The specific embodiment:
Embodiment: combine Fig. 1-4, the insulated pliers of present embodiment comprises:
A pincers seat 1, the chamber is provided with horizontal slideway within it, and the inner end of slideway is provided with spring 2;
A jacket seat 3, its flank 31 inserts in the slideway, and the length direction of slideway is provided with kidney slot 11 in pincers seat upper edge, and flank 31 is provided with the locking nut 12 that ability is slided along said kidney slot, and locking nut is used for flank 31 is locked in the optional position of slideway.
