One end that expansion loop contacts with plush copper is furnished with symmetric windows, can be furnished with 2 groups or multigroup, is opened in order to expand, deep
Enter country rock and consolidate bolt, expansion loop is made of stainless steel, and expansion loop internal diameter is bigger 1mm than the diameter of bolt, and expansion loop thickness is 1-
4mm, it can be determined according to on-site actual situations.
Nut is made of stainless steel, and with bolt using being threadedly coupled, fixed gap 3-4 is left between nut and bolt
Pitch, after squeezing into country rock so as to expansion loop, nut continues to tighten, and reduces exposed volume；Groove is provided with outside nut, it is recessed
Pip is laid inside groove, depth of groove is moderate, both protects pip, in order to avoid being destroyed, is beneficial to observation again.
Pip is laid in the conical socket of nut, is made of aluminizer, and not only reflecting effect is strong, and surface light
It is sliding, there is certain dustproof effect, other reflectorized materials can also be used.
Breach is symmetrically laid in expansion loop one end, and notch length is 2-3 pitch.
Plush copper smooth surface, protrusion angles are 30-60 °.
Above-mentioned technical proposal of the present utility model has the beneficial effect that：
On the one hand, exposed part outside is less for the device, is not easily susceptible to the destruction in the external world；On the other hand, pip
With bracing means one, pip is put into groove and protected, has both enhanced the intensity of pip, served protection again and make
With dustproof effect is also apparent from.
