The implementation principle of the wire feeding mechanism in the embodiment of the application is as follows:

(1) when the locking wire is retracted, the driving assembly 13 drives the retraction driving gear 124 to rotate, the retraction rotating shaft 122 rotates along with the retraction driving gear 124 under the action of the retraction one-way driving member 123, so that the winding member 121 rotates along with the retraction rotating shaft 122 to wind the locking wire, the sending-out driving gear 114 rotates synchronously with the retraction driving gear 124, but the sending-out one-way driving member 113 does not drive the sending-out rotating shaft 112 to rotate along with the sending-out driving gear 114 at the moment, so that the clamping member 111 and the sending-out driving gear 114 can rotate relatively;

(2) when the locking wire is fed out, the driving assembly 13 drives the feeding driving gear 114 to rotate, the feeding rotating shaft 112 rotates along with the feeding driving gear 114 under the action of the feeding unidirectional driving member 113, so that the clamping member 111 rotates along with the feeding rotating shaft 112 to convey the locking wire, while the withdrawing driving gear 124 rotates along with the feeding driving gear 114 synchronously, but the withdrawing unidirectional driving member 123 does not drive the withdrawing rotating shaft 122 to rotate along with the withdrawing driving gear 124, so that the coiling member 121 and the withdrawing driving gear 124 can rotate relatively.
