Obviously, the described implementations are only a part of the embodiments of the present invention, rather than all the embodiments.

As shown in Fig. 1-Fig. 4: a simple tie device for installing a safety rope at a side opening of the present invention includes a clamp wall fixing component, two sets of force transmission components, a force component component, and a safety rope buckle tie rod 11 , two sets of force transmission components are distributed on both sides of the clamping wall fixing assembly, and it is characterized in that: the clamping wall fixing assembly is composed of two clamping wall steel beams 1 and a pressure-bearing caliper 2. A non-slip rubber pad 10 is pasted on the inner side, and the pressure-bearing caliper 2 is provided with three card slots, which can be adapted to different wall thicknesses. , another clip wall steel beam 1 is snapped into the U-shaped groove of the pressure-bearing caliper 2 and can slide, and the safety rope buckle tie rod 11 is fixed on a clip wall steel beam 1; the force transmission component consists of two The force transmission arm 3 and the spring 9 are formed. The force transmission component is composed of two pressure-bearing washers 4, a long screw 5, a nut 6 and a wrench 7; 3 Fixed connection, the other end of the two force-transmitting arms 3 is fixedly connected with a pressure-bearing gasket 4, the spring 9 is sleeved on the long screw 5, and is located between the wall steel beam 1 and the pressure-bearing gasket 4; the other One end of the outer side of the clamp wall steel beam 1 is fixedly connected with a force-transmitting arm 3, one end of the other force-transmitting arm 3 is fixed on a slot of the pressure-bearing caliper 2, and the other end of the two force-transmitting arms 3 is connected with another pressure-bearing gasket. 4.
