Referring to fig. 1 and 2, a self-adaptive clamping mechanism of a twisted pair structure comprises a clamping rod 1 and a plurality of clamping assemblies arranged on the clamping rod 1, wherein a slide rail 3 arranged axially is arranged on the clamping rod 1, and the clamping assemblies are connected with the clamping rod 1 through a slide block 4 which is matched with the slide rail 3 and can be positioned on the slide rail 3.

The clamping assembly comprises two clamping rings 5 which are horizontally and parallelly arranged, stranded wires 2 capable of surrounding an object to be clamped are arranged in the clamping rings 5, and the projections of the two clamping rings 5 in the vertical direction are overlapped; the slider 4 is located on the outer wall of grip ring 5, and on the grip ring 5 was all located at the both ends of stranded conductor 2, one of them one end of stranded conductor 2 passed through connecting device and followed the motion of grip ring 5, and other end fixed connection is on the grip ring. Generally, the length of the strand is greater than the diameter of the clamping ring and less than the circumference of the clamping ring.

Referring to fig. 2 and 3, the inner wall of the clamping ring 5 is provided with two connecting plates 6 which are horizontally and parallelly arranged, the two connecting plates 6 are bent in opposite directions to form a connecting groove 7, a roller 8 matched with the connecting groove 7 is arranged in the connecting groove 7, and the center of the roller 8 is connected with a wheel shaft 9 extending out of the connecting groove 7; the connecting device comprises a connecting frame 11 sleeved outside the wheel shaft 9 through a bearing 10, the upper end of the connecting frame 11 is provided with a connecting seat 12 for connecting the stranded wire 2, and the connecting seat 12 is provided with a motor 13; the top surface of the clamping ring 5 is provided with a moving groove 14 arranged along the clamping ring 5, the moving groove 14 is internally provided with uniformly spaced teeth (the teeth are uniformly arranged along the circumference around the center of the clamping ring), and an output shaft of the motor 13 is sleeved with a gear 15 (the gear is a bevel gear matched with the inner teeth of the moving groove) matched with the moving groove 14.
