As shown in Figure 2 and Figure 3, spring 27 is arranged on fixing bolt 5, spring 27 is located at the first grip block 8 and the second folder
It holds between block 15.The right side of first grip block 8 and the left side of the second grip block 15 are respectively and fixedly provided with ring block 28, ring block 28
Internal diameter be greater than fixing bolt 5 diameter.Wherein the ring block 28 on the first grip block 8 is located at the outside of first through hole 10, the
Ring block 28 on two grip blocks 15 is located at the outside of the second through-hole 17.When the inner wall of the first wire casing 12 and the second wire casing 19 clamps
When conducting wire, spring 27 is in compressive state.When people need to separate conducting wire and wire clamp, unscrew fixing bolt 5, the first grip block
8 and second grip block 15 it is mobile from trend side away from each other under the elastic force effect of spring 27 so that 12 He of the first wire casing
The distance of second wire casing 19 increases, and takes out conducting wire convenient for people, has laborsaving convenient effect.
The working principle of the present embodiment:
When assembling wire clamp, fixing bolt 5 is first sequentially passed through into fixation hole 4, kidney slot 9 and first through hole 10, then by bullet
Spring 27 is set in 5 outside of fixing bolt, then gland 16, which is embedded in card slot 20, connect gland 16 with the second grip block 15, then
Fixing bolt 5 is threadedly coupled after the second through-hole 17 with fixing threaded hole 18, it is de- to prevent fixing bolt 5 that top nut is finally installed
It falls.
When conducting wire, two conducting wires are each passed through two the second wire casings 19, then tightening fixing bolt 5 makes gland 16
It is moved to the left and make the first grip block 8 and the second grip block 15 to be bonded, clamping limb 11 is embedded in the second wire casing 19 at this time, and first
The inner wall of wire casing 12 and the second wire casing 19 is by conductor clamping.Then movable block 7 is moved down, 8 stress of the first grip block is to the right
It moves and continues clamping limb 11 to the movement of the second wire casing 19, to further clamp conducting wire, will be drawn finally by mounting hole 14
Plate 13 is connect with the connector on electric pole or building.Make the first wire casing 12 and second by the fastening effect of fixing bolt 5
The inner wall of wire casing 19 clamps conducting wire, then further compresses conducting wire by the effect of movable block 7 so that wire clamp when clamping conducting wire not
It is big to the chucking power of conducting wire vulnerable to the influence of external force.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel design concept, any modification, equivalent replacement, improvement and so on should be included in the protection of the utility model
Within the scope of.
