Flexible rope pressing device and using method

The invention discloses a flexible rope pressing device comprising a first assembling component (1), a moving block (2), a rope assembly (3) and a second assembling component (4). The first assembling component (1) and the moving block (2) are connected in a threaded manner through a first threaded direction to realize moving up and down. The upper end of the rope assembly (3) and the moving block (2) are connected in a threaded manner through a second threaded direction to realize moving up and down. The first threaded direction and the second threaded direction is opposite. The lower end of the rope assembly (3) is connected to the second assembling component (4). The invention further discloses a relative using method. The flexible rope pressing device is adaptable to various flexible ropes, a high-rigidity and high-flexibility fixing manner is provided to space unfolding structure pressing, the flexible rope pressing device has the advantages of simple structure, high rigidity, high flexibility, low impact when releasing and high generality.
