Technical scheme of the present invention also has: the chute and the slide block that described overhanging reduced scale and interior shrinkage-rule are respectively equipped with coupling.
Technical scheme of the present invention also has: the material of described overhanging reduced scale and interior shrinkage-rule is fiber glass epoxy, not only insulate, and rigidity is higher, not easily bends, and can ensure measuring accuracy.
Technical scheme of the present invention also has: the upper end of described interior shrinkage-rule is provided with flange.Adopt the technical program, can easily interior shrinkage-rule be extracted out.
Technical scheme of the present invention also has: the surface of described scale scribbles Noctilucent material, can see scale clearly at night.
Technical scheme of the present invention also has: the length of described overhanging reduced scale and interior shrinkage-rule is 50 centimetres.
Technical scheme of the present invention also has: the two ends of described overhanging reduced scale are respectively provided with a rope band system ring.Adopt the technical program, rope band can be tied up on rope band system ring, facilitate staff to carry.
Technical scheme of the present invention also has: described rope band system ring is bonded and fixed on overhanging reduced scale.
Relative to prior art, the beneficial effect of insulating telescopic chi of the present invention is: can be extracted out from overhanging reduced scale by interior shrinkage-rule during use, when measuring height, retaining pawl can prevent interior shrinkage-rule at the falls downward of self gravitation, interior shrinkage-rule can be regained in overhanging reduced scale by pressing intermediate plate, is easy to carry; Overhanging reduced scale and interior shrinkage-rule are made up of insulating material, are suitable for the measurement at charged position, prevent survey crew from getting an electric shock; Can direct readout value during measurement, do not need double measurement, improve measuring accuracy.

Embodiment
For the technical characterstic of this programme can be clearly demonstrated, with reference to the accompanying drawings the specific embodiment of the invention is described further below.
As shown in Fig. 1 ~ Fig. 5, a kind of insulating telescopic chi, comprises overhanging reduced scale 1, is set in interior shrinkage-rule 2 and the Elastic buckle mechanism of overhanging reduced scale 1 inside; The length of overhanging reduced scale 1 and interior shrinkage-rule 2 is 50 centimetres; Overhanging reduced scale 1 and interior shrinkage-rule 2 are expoxy glass Steel material and make; Overhanging reduced scale 1 and interior shrinkage-rule 2 are provided with scale 3, and the surface of scale 3 scribbles Noctilucent material, are convenient to see scale clearly night; Overhanging reduced scale 1 and interior shrinkage-rule 2 are respectively equipped with chute 10 and the slide block 11 of coupling, overhanging reduced scale 1 and interior shrinkage-rule 2 can relative slidings along its length; Interior shrinkage-rule 2 is extracted out conveniently, the upper end of interior shrinkage-rule 2 is provided with flange 11; The two ends of overhanging reduced scale 1 are respectively provided with a rope band system ring 12 be bonded and fixed on overhanging reduced scale 1, rope band can be tied up on rope band system ring 12, facilitate staff to carry; Described Elastic buckle mechanism comprises intermediate plate 4, hinge 5, torsion spring 6 and retaining pawl 7; One end of described intermediate plate 4 is provided with dop 8, and the middle part of intermediate plate 4 is hinged on the sidewall of overhanging reduced scale 1 by hinge 5, and described torsion spring 6 is set in the outside of hinge 5, and dop 8 is partial to inner side under the effect of torsion spring 6; Described retaining pawl 7 is disposed on the sidewall of interior shrinkage-rule 2 along the length direction of interior shrinkage-rule 2, and described retaining pawl 7 mates with dop 8.
