It, can be by smaller resistance when stretching into cable.
Further setting：The puncture is equipped with reset assembly, and the reset assembly includes being punctured the perforative limit of needle
Block is sheathed on puncture needle and both ends contradict elastic component at the top of limited block and puncture needle respectively.
By using above-mentioned technical proposal, reset assembly in use, after being squeezed by external force, can answer automatically
Position, original state is back to by puncture needle top, and puncture needle is made to be not easy to contradict onto cable in the case of not by external force.
Further setting：The limited block is fallen in sliding slot, and the two side of the sliding slot is equipped with for position limiting slide block
Limiting slot, the sliding block both sides are extended with wing, and the wing is fallen in limiting slot.
By using above-mentioned technical proposal, sliding block is limited by wing, not easily to fall off in sliding process；Limiting slot is hidden in
It is small by ectocine in sliding slot, it is not easy to plug.
Further setting：The reset assembly further includes the compression spring for respectively falling in limited block both sides, the both ends of each compression spring
Sliding slot end, limited block side wall are contacted at respectively, are arranged independently of each other between the compression spring and sliding slot, the compression spring and limited block
It is connected.
By using above-mentioned technical proposal, the relative position relation between sliding block and sliding slot is defined by compression spring, is being drawn
During opening insulation rubber, and stop sliding, need during pushing, sliding block can be limited, it is made to be not easy back and forth to alter
It is dynamic, it is held only in the state of vertical and straight movement as possible.
Further setting：When two compression springs are in original state, axial length is equal.
By using above-mentioned technical proposal, when two compression springs are in original state, puncture needle falls the interposition in sliding slot
It sets, needs to push puncture needle when using, puncture needle reciprocating motion is driven to scratch insulation epidermis, need to insert using puncture needle when follow-up
When entering in cable, puncture needle is pushed from the centre position of opening portion, and the deformability that can be born herein is entirely to be open
Maximum puncture needle is penetrated convenient for pushing insulation epidermis aside.
Further setting：The tip of the puncture needle is set as wedge shape, and the wedge-shaped side of the tip of the puncture needle is parallel to
Limit the axis of clamp ring.
By using above-mentioned technical proposal, for puncture needle when scratching insulation rubber, the tip of puncture needle contradicts insulation rubber,
And the tip of puncture needle is equivalent to the knife edge, convenient for cutting open insulation rubber.
Preferably, the puncture needle is vertically arranged, the sliding slot is located at the vertical height highest point of limit clamp ring.
By using above-mentioned technical proposal, puncture needle keeps vertical state to cut cable, is put compared to inclination
Structure, the relative position relation between puncture needle and cable is more reliable, is not easy to cut partially.
In conclusion the utility model has the advantages that：
1, in actual use, cable can be punctured the multiple cutting-up of needle, even if encountering thicker insulation epidermis,
The mode repeatedly cut may be used to be scratched；
2, compression spring and elastic component are for the position of puncture needle and cable to be defined, what is do not exerted a force to puncture needle
Under state, puncture needle is not easy to impact cable.
