It can be seen that the plurality of second floating springs 10 realize the buffering downward pressure and reset of the needle plate 7.

[0017] like Figure 1 and Figure 4 As shown, in this embodiment, a pressing plate 12 is provided at the upper end of the carrier 4, one side of the pressing plate 12 is hinged to one side of the carrier 4, the pressing end of the pressing plate 12 is matched with the product 9 on the other side of the carrier 4, and the pressing end of the pressing plate 12 is provided with a lower needle slot 13, and the probe end of the needle plate 7 is matched with the connecting end of the product 9 through the lower needle slot 13.
