The auxiliary support structure 40 is used to support the second hanging component 20.

[0043] In this embodiment, the first hanging component 10 is hung on the angle iron.

At the same time, an auxiliary support structure 40 is also arranged on the first hanging component 10, and the telescopic end of the auxiliary support structure 40 is connected to the second hanging component 20, thereby forming a support for the second hanging component 20, preventing the second hanging component 20 from rotating and detaching from the locking unit 30 during the locking process, improving safety, and having good practicability.

[0045] Preferably, a differential fall arrester is used to connect the safety belt and the anti-falling hook device to prevent the operator from falling from a height. When the differential fall arrester is in normal use, the safety rope can freely stretch and contract with the movement of the human body, so that the operator has no sense of entanglement. In case the operator slips and falls, the pulling speed of the safety rope will increase significantly, and the locking system in the differential fall arrester will automatically lock, and the safety rope will stop pulling out after a short distance is pulled out, preventing the operator from continuing to fall.

[0046] In some embodiments, please refer to Figures 1 to 3 and Figure 5 , the first hanging component 10 includes a hanging member 11 and a vertical rod 12. The hanging member 11 is hung on the horizontal side plate of the angle iron. The vertical rod 12 is connected to the hanging member 11 and abuts against the vertical side plate of the angle iron. In this embodiment, the hanging member 11 is hung on the horizontal side plate of the angle iron, and the vertical rod 12 abuts against the vertical side plate of the angle iron, so that it can be abutted and connected to the angle iron. Specifically, the hanging member 11 is hook-shaped.

[0047] In some embodiments, please refer to Figure 2 and Figure 3 , the second hanging component 20 includes an enclosing limiting member 21 and a connecting rod 22. The number of the enclosing limiting members 21 is two, and the two enclosing limiting members 21 are respectively arranged on both sides of the first hanging component 10, and the two enclosing limiting members 21 are both rotatably connected to the first hanging component 10. The connecting rod 22 is arranged between the two enclosing limiting members 21, and both ends of the connecting rod 22 are respectively connected to the two enclosing limiting members 21. In this embodiment, the enclosing limiting members 21 are respectively arranged on both sides of the first hanging component 10, and the two enclosing limiting members 21 and the hanging member 11 enclose a space for accommodating the angle iron and are fixed on the angle iron. The two enclosing limiting members 21 are connected by the connecting rod 22, so as to enhance the fixing stability on the angle iron.

[0048] In some embodiments, please refer to Figures 1 to 4 , each enclosing limiting member 21 includes an abutting plate 211, a first enclosing plate 212 and a second enclosing plate 213. The abutting plate 211 abuts against the horizontal side plate of the angle iron. One end of the first enclosing plate 212 is connected to the abutting plate 211. The second enclosing plate 213 has a first connection end and a second connection end. The first connection end is connected to the other end of the first enclosing plate, and the second connection end is snap-connected to the locking unit 30. In this embodiment, the abutting plate 211, the first enclosing plate 212 and the second enclosing plate 213 form a C-shaped structure, and the second connection end of the second enclosing plate 213 is a free end. During the installation process, the second connection end is snap-connected to the locking unit 30. During the disassembly process, the connection between the second connection end and the locking unit 30 is loosened, and the abutting plate 211, the first enclosing plate 212 and the second enclosing plate 213 rotate to loosen the enclosure of the angle iron, so as to facilitate disassembly from the angle iron.

[0049] In some embodiments, please refer toFigure 1 The locking unit 30 includes a rotating connecting member 31, a clamping rod 32, a sliding rod, and an elastic connecting member 33. The rotating connecting member 31 is pivotally connected to the vertical rod 12 for pitching. The number of the clamping rods 32 is two, and the two clamping rods 32 are arranged in one-to-one correspondence with the two second enclosing plates 213. The two clamping rods 32 are respectively arranged on both sides of the rotating connecting member 31 and are clamped to the corresponding second connecting ends. One end of the sliding rod is connected to the rotating connecting member 31, and the other end is slidably connected to the vertical rod 12. The elastic connecting member 33 is sleeved on the sliding rod. One end of the elastic connecting member 33 is connected to the vertical rod 12, and the other end is connected to the rotating connecting member 31. Wherein, a clamping groove 214 is provided at the second connecting end. A sliding hole adapted to the sliding rod is provided on the vertical rod 12. In this embodiment, during the locking and fixing process, the rotating connecting member 31 is pushed upward, the sliding rod slides, and the clamping rod 32 rotates to the position of the clamping groove 214 of the second connecting end and is clamped to the second connecting end. Specifically, during the process of the clamping rod 32 being clamped in the clamping groove 214, the elastic connecting member 33 is in a stretched state, and under the action of the elastic force, the rotating connecting member 31 has a tendency to rotate upward (the clamping rod 32 moves downward), thereby enhancing the connection stability between the rotating connecting member 31 and the second enclosing plate 213.

[0050] In some embodiments, please refer to Figure 1 The rotating connecting member 31 includes a main board 311 and connecting plates 312.

[0051] Preferably, the elastic connecting member 33 can be a tension spring. During the disassembly process, it is necessary to pull the rotating connecting member 31, and the rotating connecting member 31 rotates downward, so that the clamping rod 32 disengages from the clamping groove 214 of the second enclosing plate 213. If the rotating connecting member 31 is accidentally touched, the rotating connecting member 31 may be squeezed and rotate upward, and the rotating connecting member 31 will also be clamped tighter and tighter with the second enclosing plate 213.

[0052] In some embodiments, please refer to Figure 1 and Figure 3 A handle 34 is provided on the rotating connecting member 31, which is convenient for the operator to adjust the position of the rotating connecting member 31.

[0053] In some embodiments, the sliding rod includes a rod body and a limiting block. The limiting block is arranged at one end of the rod body located in the sliding hole, so as to prevent the sliding rod from disengaging from the vertical rod 12 during the sliding process.

[0054] In some embodiments, please refer to Figure 2, the auxiliary support structure 40 includes two telescopic support members 41. The two telescopic support members 41 are arranged in one-to-one correspondence with the two enclosing limit members 21. Each telescopic support member 41 has a fixed end and a telescopic sub-end. The fixed end is connected to the vertical rod 12, and the telescopic sub-end is connected to the corresponding enclosing limit member 21. In this embodiment, the telescopic support member 41 is used to support the enclosing limit member 21 to prevent the position of the enclosing limit member 21 from shifting and ensure the locking and fixing effect on the angle iron. Specifically, the telescopic support rod can be an electric push rod. During the locking process, the telescopic support rod always supports the enclosing limit member 21. During the disassembly process, the telescopic sub-end of the telescopic support rod moves downward and disengages from the enclosing limit member 21, and the enclosing limit member 21 can rotate to disengage from the clamping rod 32.

[0055] In some embodiments, please refer to Figure 3 , a semi-circular arc-shaped groove 215 is provided on each limit member, and a sphere adapted to the semi-circular arc-shaped groove 215 is provided at the telescopic sub-end of each telescopic support member 41.
