An end of the second connecting part 70 is disposed with a third connecting portion 100, another end of the second connecting part 70 is provided with a fourth connecting portion 110, an end of the fourth connecting portion 110 is formed with a holding groove 111.
An end of the adjusting rod 80 is disposed inside the holding groove 111, the adjusting rod 80 is screw-connected to an inner wall of the holding groove 111.
The second clamping member 90 is disposed on another end of the adjusting rod 80 away from the second connecting part 70.
In conjunction with the rope connector 1000, the adjusting rod 80 is configured to adjust tension of the rope 3000. The rope connector 1000 and the rope connection component 4000 are installed and fixed firstly, then two ends of the rope 3000 are respectively connected to the rope connector 1000 and the rope connection component 4000, and finally the tension of the rope 3000 is adjusted through the adjusting rod 80, so that the rope assembly 2000 can be assembled and installed more convenient and fast, which make its use be more convenient. Due to the installation method of hard tension of bolts to the two ends of a rope assembly in prior art, during installation process of the rope assemblies, 9 rows of rope assemblies are generally installed, the middle row of rope assembly is installed firstly, and then 8 rows of rope assemblies which are upper and lower than the middle row of rope assembly are installed in sequence. During the installation process, bolts at two ends of each row of rope assembly are pre-locked firstly, and then their tightness of each bolt is adjusted as a whole, so as to make tension states of 9 rows of rope assemblies be consistent. The rope assemblies often need to be adjusted many times, which is very troublesome. However, for the rope assembly of the disclosure, only the rope connection component 4000 of each row of rope assembly needs to be adjusted so as to achieve the same tension state of the rope 3000, without the adjustment of both ends of the rope assembly, which can greatly improve installation efficiency of the rope assembly 2000. In addition, after the rope 3000 is tensioned, a force in axial direction is an elastic force, which is smaller than a rigid locking force, so that a radial load which the rope 3000 bears is smaller relatively, so as to extend service life of the rope 3000. Since the aforementioned rope connector 1000 is applied, the rope assembly 2000 also has all the beneficial effects brought by the embodiment of the rope connector 1000, and there no more details here.

The third sleeve 91 can be made of metal or plastic. When an end of the rope 3000 passes through the third hole 911 and is disposed between the second abutting blocks 94, the adjusting rod 80 is rotated to move inwardly inside the third sleeve 91, so as to make the adjusting rod 80 push the second abutting blocks 94 moving towards the third hole 911 along the inner wall of the tapered structure in the third sleeve 91 synchronously. The distance between the second abutting blocks 94 is correspondingly reduced so that the rope 3000 is clamped and connected to the second clamping member 90. When the rope 3000 is separated from the second clamping member 90, the adjusting rod 80 is rotated to move out of the third sleeve 91, so as to reduce thrust from the adjusting rod 80 against the second abutting blocks 94 until the thrust disappears. The clamping forces between the second abutting blocks 94 and the rope 3000 also disappear gradually. The rope 3000 can be separated from the second clamping member 90, so as to realize that fast connection and separation between the rope 3000 and the second clamping member 90, and make its use be more convenient.
