[0023] In order to facilitate the reset between the handle 1 and the clamping rod 3 after the handle 1 stops being pulled, a spring 4 is sleeved on the outer side of the clamping rod 3 and located inside the connecting shell 2. One end of the spring 4 is fixed to the clamping rod 3, and the other end of the spring 4 is fixed to the connecting shell 2. At the same time, when the twisted pair is not clamped, the spring 4 prevents the handle 1 from being separated from the clamping rod 3.

[0024] The handle 1 and the connecting shell 2 are detachably connected. When the handle 1 and the connecting shell 2 are detached, the connecting shell 2 and the hand drill are installed, and the hand drill is pulled to drive the connecting shell 2 away from the wire clamping support rod 3, so that the twisted pair wire ends can be clamped to be straightened and automatically untwisted;

[0025] Push the connecting housing 2 to move away from the handle 1, so that the clamping arc block 9 is as shown in FIG. Figure 2The handle 1 is pulled away from the clamping rod 3 so that the connecting shell 2 moves synchronously with the handle 1. The first derivation groove 10 fits with the clamping arc block 9 so that the connecting shell 2 pushes the clamping arc block 9 to rotate around the support shaft 8 as the axis when moving, so that the end of the clamping arc block 9 located inside the wire placement slot 5 can rotate the twisted pair wire head. The handle 1 is clamped and fixed, so that before the twisted pair is separated from the wire clamping support rod 3, the twisted pair head can be clamped and straightened by pulling the handle 1, and the greater the force of pulling the handle 1, the tighter the twisted pair head is clamped, so that it is convenient to rotate and untwist the twisted pair while straightening the twisted pair, and the untwisting and straightening can be carried out simultaneously. Compared with the method of pinching the twisted pair head and rotating to untwist, the untwisting speed is effectively increased and the labor intensity is reduced, and there is no need to straighten the wire after untwisting. After the untwisting and straightening are completed, stop pulling the handle 1 and reset the wire clamping support rod 3 and the handle 1 through the spring 4.

[0028] When in use, the electromagnetic switch 16 is pressed to energize the electromagnet 11, pushing the metal housing 18 to move toward the direction of the clamping support rod 3 so as to open the clamping arc block 9. Figure 2As shown, it is tilted, so that it is convenient to place the twisted pair wire head into the inner side of the wire placement slot 5 through the wire entry port 6, release the electromagnetic switch 16 to cut off the power of the electromagnet 11, and then reset the metal shell 18 through the spring 4, so that the wire clamping arc block 9 clamps the twisted pair wires in cooperation with the second derivation groove 19. At this time, the DC motor 13 is adjusted to a suitable speed by rotating the motor speed control switch 17, and the motor switch 15 is pressed to start the DC motor 13 while holding the insulating shell 12 to tighten the twisted pair wires, and then the output end of the DC motor 13 is rotated a corresponding number of times to untie the twisted pair wires, and then the electromagnet 11 is reopened to loosen the twisted pair wires, completing the twisted pair wire unwinding and straightening operation.
