An extension rod 13 is provided at the bottom of the thread drum 3-4, and an extension thread hole 14 is provided at the end of the extension rod 13. The number of extension racks 3-3 and thread drums 3-4 is three, and the position of the extension rod 13 corresponds to that of the extension rack 3-3.

[0043] In this embodiment, the fixed wire hole 12 on the wire feeding frame 11 is used for feeding wires, and the extension rod 13 and the extension wire hole 14 are also used for feeding wires.

[0044] When the spool needs to be placed, the rotating disk 3-2 on the stand 3-1 can be rotated to adjust the position of the spool 3-4, and the spool can be placed on the spool 3-4 for use. The spool is clamped by the clamping disk 3-6 on the clamping frame 3-5, and the spool is pressed and fixed from above by the pressing rod 3-7, so that the spool is more stable during the wire feeding process. When the pulling spring 4-2 is pulled, the sliding clamping groove 7 and the sliding clamping bar 8 can be used for sliding limitation, so that the lifting and lowering are more stable. The spool is inserted into the fixed shaft 9, and the spool is limited by the stepped clamping ring 10, so that the spool can only rotate on the stepped clamping ring 10 to achieve the wire feeding effect. When the spool is placed, the clamping disk 3-6 is lifted and then placed to clamp and fix the spool.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
