It should be noted that the lifting rods 5 are driven by external equipment to move. This technology is existing technology and will not be elaborated on here. A plurality of partitions 6 are evenly provided, and a cavity 7 is formed between two adjacent partitions 6. A wire-passing device 8 is provided under the partition 6, and the wire-passing device 8 is fixedly connected to the mounting plate 2; a plurality of upper threading holes 9 are evenly provided on the upper end of the top plate 4, and a plurality of lower threading holes 10 are provided on the upper end of the base 1. The number of the upper threading holes 9, the lower threading holes 10, the cavity 7 and the lifting rod 5 is the same. Further, the number of the upper threading holes 9, the lower threading holes 10, the cavity 7 and the lifting rod 5 is ten;

[0023] That is, the embroidery thread 12 passes through the upper threading hole 9, then passes through the thread passing device 8, goes around into the cavity 7, passes through the threading hole 11, and finally passes through the lower threading hole 10. This arrangement can avoid the embroidery thread 12 from skipping and also reduce the thread breakage rate here; and by providing a plurality of cavities 7, each thread has a separate cavity, which avoids the phenomenon of multiple embroidery threads being entangled, thereby improving the efficiency of embroidery;

[0024] In this embodiment, a sealing plate 13 is provided on one side of the front end of the partition 6;
