Detailed description of the invention
Embodiment 1
As depicted in figs. 1 and 2, the utility model comprises anchor cable 1 and is close to the anchor cable backing plate 2 that country rock 5 outer walls arrange, described anchor cable backing plate 2 be shaped as wedge shape, described anchor cable backing plate 2 dorsad on the lower surface, one end of country rock 5 outer walls center position be provided with groove 6, in described groove 6, engagement connection has anchor cable pallet 3, the geometric center position that is positioned at described groove 6 on described anchor cable backing plate 2 has and 6 the first through holes 7 perpendicular and that pass for anchor cable 1 of described groove, the geometric center position of described anchor cable pallet 3 has the second through hole that is connected with described the first through hole 7 and passes for anchor cable 1, described anchor cable 1 also tilts to penetrate in country rock 5 through described the second through hole and the first through hole 7 successively, be exposed at outward on one section of anchor cable 1 of described the second through hole outside and be connected with for anchor cable 1 being anchored to the ground tackle 4 on anchor cable pallet 3.
