[0020] The yarn bobbin 3 is connected to the transmission shaft 2 through a connecting unit 7. The connecting unit 7 includes a cavity 701, a through hole 702, a rubber ring 703, an air injection pipe 704, a valve 705 and a joint 706. The cavity 701 is opened inside the transmission shaft 2. A plurality of through holes 702 are evenly and equidistantly opened on the upper and lower sides of the inner wall of the cavity 701. A rubber ring 703 is arranged outside the through hole 702. The rubber ring 703 can be connected to the inside of the cavity 701 through the through hole 702. The rubber ring 703 is made of rubber material and has a certain degree of flexibility.

[0021] During the use of the yarn winding mechanism, the operator first sleeves the yarn bobbin 3 above the rotating shaft 2, and can connect the air supply pipe to the joint 706 to inject air into the cavity 701, so that the air pressure inside the cavity 701 and the rubber ring 703 can be increased.

Due to the sliding limit relationship between the slide groove 503 and the slider 502, the transmission shaft 3 and the yarn drum 3 can rotate. The yarn drum 3 in the rotation process can perform the winding operation on the connected yarn. When the yarn supply jams during the winding operation, the torque required for the rotation of the yarn drum 3, the transmission shaft 2, the insertion rod 501, the first circular plate 504 and the first magnetic suction piece 505 gradually increases. When it is greater than the mutual attractive force between the first magnetic suction piece 505 and the second magnetic suction piece 507, a rotation difference occurs between the first magnetic suction piece 505 and the second magnetic suction piece 507, that is, when the motor 4 is running, it no longer provides the yarn drum 3 with the kinetic energy required for rotation, so that the safety performance during the yarn winding operation is improved.
