The connecting mechanism 11 further includes a connecting sleeve 111, the connecting frame 113 is mounted on the periphery of the connecting sleeve 111, and the connecting frame 113 is driven to move by the rotation of the connecting sleeve 111. The connecting sleeve 111 and the linkage shaft 101 rotate synchronously and can be adjusted in an axial sliding mode, and a key groove 1032 structure can be arranged between the connecting sleeve 111 and the linkage shaft 101 to achieve connection.

The periphery of the upper end of the connecting sleeve 111 is fixedly connected with a limit stop ring 115, and the lower end of the linkage spring 104 can be stopped by the limit stop ring 115 to form an elastic supporting structure at the lower end of the linkage spring 104; and the lower end of the linkage shaft 101 is in threaded connection with a linkage nut 105, the linkage nut 105 can be abutted against and limited at the lower end of the connecting sleeve 111 to integrally support the connecting sleeve 111 and the linkage spring 104, and the initial pre-tightening force of the linkage spring 104 can be adjusted by adjusting the position of the linkage thread before assembly, so that the winding tightness of the cable 12 is adjusted. The linkage nut 105 can adopt two mutually overlapped modes, and the two linkage nuts 105 can be mutually pressed through relative adjustment to generate the pressure of a threaded part, so that the linkage nut 105 and the linkage shaft 101 are locked.

As shown in fig. 5, the driven sleeve 112 is hermetically connected to the periphery of the connecting sleeve 111, a sealed damping cavity 116 is arranged between the connecting sleeve 111 and the driven sleeve 112, damping oil is filled in the damping cavity 116, the damping oil has low fluidity, and a more stable state can be formed in the mutual rotation process between the connecting sleeve 111 and the driven sleeve 112; specifically, a damping seat 117 can be fixedly connected to the outer periphery of the connecting sleeve 111 at a position corresponding to the damping cavity 116, a damping fin 118 is arranged on the outer periphery of the damping seat 117, and a smaller gap is formed between the damping fin 118, the damping seat 117 and the inner wall of the damping cavity 116, so that damping oil is more difficult to circulate, and the damping transmission stability between the driven sleeve 112 and the connecting sleeve 111 is maintained.

the expansion and contraction of the damper 118 is adjusted by the inclination thereof, specifically, as shown in fig. 6, a third inclined surface 1110 is provided on the damper 118 on the side of the end portion facing the inner peripheral wall of the driven sleeve 112, and the third inclined surface 1110 can be pressed and sealed with the inner peripheral wall of the driven sleeve 112; a flow limiting groove 1111 is formed in one side, back to the three inclined surfaces 1110, of the damper 118, and a four inclined surfaces 1112 parallel to the three inclined surfaces 1110 are formed in the flow limiting groove 1111.

Under the working condition, the linkage shaft 101 drives the connecting sleeve 111 to rotate, the rotation direction faces one side of the flow limiting groove 1111, in the rotation process, the damping oil can generate radial component force on the inclined plane four 1112, and can drive the damping sheet 118 to have a radial outward movement trend, so that the damping sheet 118 and the inner peripheral wall of the driven sleeve 112 can be driven to form a tighter pressing state, and a more stable damping state can be formed; under the condition that the first linkage sleeve 102 and the second linkage sleeve 103 are used for guiding sliding, the continuous rolling tightness of the cable 12 can be buffered through slow damping, and the abrasion possibly generated by long-time frequent sliding buffering is reduced;

then, under the condition that the linkage shaft 101 does not rotate, in the damping cavity 116, the damping oil forms slow pressure release on two sides of the damping fin 118, the circulating damping oil is easier to circulate at the edge position of the inclined plane three 1110, and further a certain inward radial component force is generated at the position of the inclined plane three 1110, so that a gap structure is easier to form between the damping fin 118 and the damping cavity 116, and the damping oil can automatically recover to a stable state.

Further, the above embodiment can be optimized, as shown in fig. 7 and 8, an elastic buffer sleeve 16 can be fixedly connected to the lower end of the driven sleeve 112, a buffer gap 161 is formed between the elastic buffer sleeve 16 and the connection sleeve 111, a buffer spring 163 is arranged in the buffer gap 161, and an elastic restoring force can be formed between the elastic buffer sleeve 16 and the connection sleeve 111 through the buffer spring 163, that is, in the winding process, the buffer spring 163 can stop winding the linkage shaft 101, and when the relatively stable state is restored, the torque generated in the damping motion process is slowly released through the elastic action of the buffer spring 163, and thus, proper unwinding adjustment can be generated, and the situation that the cable 12 is wound too tightly for a long time is avoided.

Specifically, the buffer blocks 162 are fixedly connected to two ends of the buffer spring 163, the buffer blocks 162 at two ends are respectively and fixedly connected to the connection sleeve 111 and the elastic buffer sleeve 16, and an elastic connection structure is formed between the buffer spring 163 and the connection sleeve 111 and the elastic buffer sleeve 16.

In order to improve the stability of the damped rotation between the connection sleeve 111 and the elastic buffer sleeve 16, the buffer spring 163 can be replaced by a volute spring 164; as shown in fig. 9, an elastic buffer sleeve 16 is fixedly connected to the lower end of the driven sleeve 112, a buffer gap 161 is formed between the elastic buffer sleeve 16 and the connecting sleeve 111, a spiral spring 164 is arranged in the buffer gap 161, buffer blocks 162 are fixedly connected to both ends of the spiral spring 164, the buffer blocks 162 at both ends are respectively fixedly connected to the connecting sleeve 111 and the elastic buffer sleeve 16, and the spiral spring 164 is wound in the buffer gap 161; the volute spring 164 can have a larger rotation angle, so that stability in a damping and buffering adjusting process generated between the connecting sleeve 111 and the elastic buffering sleeve 16 is kept, and the winding action of the cable 12 is facilitated.
