The retraction degree of the two first conflicting ends can thereby estimate the position of the second conflicting end, thereby further improving the positional accuracy of the connecting rod and the adjustment accuracy of the yarn guide.

5. There is an installation error between the parts on the adjustment device. The zero position of the adjustment rod is determined by the zero adjustment device, and the position of the corresponding feedback mechanism is memorized. Before zero adjustment, the coil is energized to generate a magnetic field, which interacts with the magnet to make the movement The core moves to eject the buffer seat, and the adjustment rod moves to the zero point position when the connecting piece and the contact contact, which is convenient for the electrical connection of the two contacts, and the hollow cylinder and the fourth spring increase the buffering effect when the connecting piece and the contact are in contact. After the zero adjustment is completed, the coil stops energizing, and the contact is contracted under the action of the third spring and the end plate, which reduces the collision between the connecting piece and the contact when the adjustment rod is normally zero adjusted. At zero time, the contact is ejected through the coil energization again, which increases the service life of the contact and improves the stability and accuracy of the adjustment device.
