The pin fixing plate 32 is fixedly fitted on the fixture base plate 1, the adapter pin assembly 31 is fixedly fitted on the pin fixing plate 32, the floating plate 33 is floatingly fitted with the pin fixing plate 32 through the first-layer floating assembly 34, the floating pin assembly 30 is limited and fitted on the floating plate 33, and the floating pin assembly 30 is floatingly fitted with the floating plate 33 through the second-layer floating assembly 35. Both the floating pin assembly 30 and the adapter pin assembly 31 are connected to the drive assembly on the drive fixing plate 2 through an FPC flexible flat cable 36. Therefore, the fixture base plate 1 provides support and fixation for the needle block fixing plate 32, and the needle block fixing plate 32 provides support and limitation for the adapter needle block assembly 31 and the first-layer floating assembly 34. The adapter needle block assembly 31 is fixedly fitted to the needle block fixing plate 32.
