It is composed of interconnected grids to form a safety net that can disperse and absorb the weight and kinetic energy of a falling person. When a fall occurs, the grid absorbs energy by tearing and deforming, thereby slowing down the falling person and keeping him / her safely on the net, preventing the falling person from hitting the ground or other dangerous surfaces, thereby minimizing the risk of injury or death.

[0025] Specifically, the auxiliary structure 13 is composed of four parts: a first thread groove 131, a first fixing bolt 132, a second thread groove 133 and a second fixing bolt 134. The first thread groove 131 is opened on the top of the support frame 5, and the internal thread of the first thread groove 131 is connected to the first fixing bolt 132. The second thread groove 133 is opened on the top of the guide rod 12, and the internal thread of the second thread groove 133 is connected to the second fixing bolt 134. The first fixing bolt 132 is located above the connecting ring 4, and the second fixing bolt 134 is located above the connecting seat 3. The connecting ring 4 is limited by the cooperation of the first thread groove 131 and the first fixing bolt 132, and the connecting seat 3 is limited by the second thread groove 133 and the second fixing bolt 134.
