[0024] like Figures 1 to 6 As shown, the fast-link safety fence of the present invention includes a mounting base 1, a column 2 and a protective net 3. The lower end of the column 2 is provided with a support foot 2a. The mounting base 1 has a rectangular cross-section that passes through from top to bottom and is sleeved on the column 2; the four walls of the mounting base 1 are respectively connected with claws 1a, and the roots of the claws 1a are bent toward and connected to the outer wall of the mounting base 1. A slot for inserting a square tube 3a is formed between the claws 1a and the outer wall of the mounting base 1.

[0025] The claw 1a on the short side of the mounting base 1 is located in the middle, and the claw 1a on the long side of the mounting base 1 is biased to one side. A screw hole 1b is provided on the other side of the long side for the set screw 4 to be screwed in. The inner end of the set screw 4 rests against the outer wall of the column 2 to lock the mounting base 1 on the column 2.
