[0037] like Figure 1 and Figure 2 As shown, the fastener body 12 is configured as a C-shaped structure with an opening toward one side, and the internal space of the opening forms a clamping cavity 121 .

[0038] Through the clamping cavity 121 , the staff can move the installation fastener 1 along the steel structure 3 according to actual installation requirements. The flexible structure facilitates the adjustment of the relative clamping position of the installation fastener 1 .

[0039] To further facilitate the clamping operation, the height of the clamping cavity 121 decreases gradually in the direction away from the opening, and its cross section is as follows: Figure 2 As shown, it is a trapezoid.

[0040] Preferably, the width of the opening is set to 43 mm, and the depth of the opening is set to 30 mm, which is suitable for most steel structures 3, such as I-beams, C-beams, steel plate platforms, etc.

[0041] As an optional implementation, the hanging portion 11 is configured as a hanging strip, and the hanging strip is fixedly disposed on the top of the fastener body 12 .

[0042] The hanging method is adopted, which not only makes the anti-fall net firmly installed, but also convenient to install.

[0043] As an optional implementation, the hanging strip includes a fixing section 111 and a hanging section, and the fixing section 111 and the hanging section are integrally provided.

[0044] The fixing section 111 is horizontally fixedly disposed on the top of the fastener body 12 , and the hanging section is connected to one end of the fixing section 111 .

[0045] The fixing section 111 is used to connect the fastener body 12, and the hanging section is used to hang the anti-fall net.

[0046] As an optional implementation, the hanging section includes a first hanging section 112, the bottom end of the first hanging section 112 is connected to an end of the fixing section 111 away from the opening, and the top end of the first hanging section 112 is inclined toward the opening.

[0047] In this way, an acute hanging angle is formed between the first hanging section 112 and the fixing section 111, so that the hanging is more stable and not easy to fall off.

[0048] Preferably, the included angle between the first hanging section 112 and the fixing section 111 is set to 65°, so that the anti-falling net is not easy to be unhooked.

[0049] As an optional implementation, the hanging section includes a second hanging section 113, the bottom end of the second hanging section 113 is connected to the top end of the first hanging section 112; the top end of the second hanging section 113 is inclined in a direction away from the opening.

[0050] In this way, when installing the anti-falling net, the top end of the second hanging section 113 faces the staff, making the hanging operation more convenient.

[0051] Preferably, the angle between the second hanging section 113 and the first hanging section 112 is set to 90°. During installation, the anti-fall net can be quickly introduced into the first hanging section 112 to achieve hanging.

[0052] As an optional implementation, the locking member 2 can be rotatably disposed on the fastener body 12 .

The operating end of the stud 21 is located outside the clamping cavity 121.

[0056] During installation, the installation fastener 1 is clamped on the steel structure 3 through the clamping cavity 121. After being clamped in place, the operating end of the stud 21 is rotated, and the stud 21 moves axially along the threaded hole 122, and its abutting end abuts against the steel structure 3, thereby locking the relative clamping position of the installation fastener 1 and the steel structure 3.

[0057] It adopts thread locking structure, which has simple structure and significant locking effect.

[0058] As an optional implementation, a pressing portion 22 is provided at the abutting end of the stud 21 .

[0059] The pressing portion 22 is configured as a pressing block, the size of which is larger than the diameter of the threaded hole 122 , so that, on the one hand, it can steadily press the steel structure 3 to further improve the stability of the installation, and on the other hand, it has a limiting effect to prevent the locking member 2 from detaching from the mounting fastener 1 .

[0060] As an optional embodiment, the operating end of the stud 21 is provided with a toggle portion 23 .

[0061] The toggle portion 23 is configured as a toggle block, and the number of the toggle blocks is configured to be multiple and uniformly arranged along the circumference of the operating end of the stud 21 , so that the locking member 2 can be rotated only manually.
