Preferably, the interval between the spring ropes is 5-10 m.

Compared with the prior art, the utility model discloses a characteristics and beneficial effect do:

(1) the utility model provides a telescopic safe anti-falling net of spring connects into latticed spring net with a plurality of spring ropes, and the binding can be dismantled in the junction setting of spring rope, and the both ends of spring rope are all connected and are broken out for with structural connection. Because the spring rope has elasticity, the position of the detachable fastener is only required to be adjusted, the falling-preventing net can be well adapted to holes with different sizes, and the repeated utilization rate of the falling-preventing net is improved.

(2) The utility model discloses a telescopic safe anti-falling of spring net still is connected with fastener between spring rope and break out, strengthens being connected between spring rope and the break out, improves factor of safety.

(3) The utility model discloses a telescopic safe anti-falling net of spring simple structure, the cost of manufacture is lower, and the installation is dismantled all very conveniently moreover, improves the efficiency of construction.
