In addition, if there is no suitable hook, some construction personnel use steel wires to bundle and fix the safety net. This fixing method also has significant problems. On the one hand, the steel wire fixing is not firm and is prone to slipping. On the other hand, due to the lack of a suitable root point, the fixing position of the steel wire is difficult to determine, which brings inconvenience to construction.

[0004] Therefore, it is necessary to design a portable hook tool. As a further improvement, this can reduce the consumption of labor and materials, and can be recycled and reused after the project is completed, thereby achieving the purpose of improving construction safety. SUMMARY

On the one hand, it can avoid the stress being too concentrated after laying the safety net, and on the other hand, it is convenient to connect the safety net to the connecting portion 1. In addition, the clamping strip 6 and the limiting slot 5 are both polygonal in shape. In this example, preferably, the clamping strip 6 and the limiting slot 5 are both quadrangular in shape. When the clamping strip 6 is inserted into the inside of the limiting slot 5, it cannot be axially rotated, and at the same time, the bolt 3 on the connecting portion 1 is tightened to fix the clamping strip 6 in the inside of the limiting slot 5, thereby playing a role of fixing the limiting section.
