detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Shown in Fig. 7, a kind of plug-in Sewing machines crosspointer joint, has eedle connecting rod 1 and the eedle joint for installing sewing machine needle 4; Described eedle joint is made up of guide-localization block 2 and eedle contiguous block 3; As shown in Figure 1 to Figure 3, the end face of described guide-localization block 2 is in falling T-shape, eedle connecting rod 1 is arranged on the top center of guide-localization block 2, and the top of described guide-localization block 2 is provided with screwed hole, eedle connecting rod 1 end is provided with the external screw thread closed with described corresponding threaded holes, facilitates eedle connecting rod 1 to dismantle; One side of described guide-localization block 2 is provided with has flexible locating convex block 21; For the ease of installing locating convex block 21, and ensure that it has certain elasticity, the ladder pilot hole 22 communicated before and after the side of described guide-localization block 2 is provided with, locating convex block 21 is positioned at ladder pilot hole 22, its head extends in the outside of aperture on ladder pilot hole 22, the end of described locating convex block 21 matches with the macropore of ladder pilot hole 22, and being provided with spring 23 in its rear end ladder pilot hole 22, described spring 23 is spacing by the counter sink bolt 24 being screwed in the large bore end of ladder pilot hole 22; As shown in Figures 4 to 6, the top of described eedle contiguous block 3 is provided with the gathering sill 31 that can coordinate with guide-localization block 2 plug-in type, described gathering sill 31 one end is closed, the other end communicates with the outer face of eedle contiguous block 3, the bottom of described gathering sill 31 is provided with two holes 32 embedding with the eedle communicated bottom eedle contiguous block 3, for the ease of assembling sewing machine needle 4, planform and the sewing machine needle 4 in the embedding hole 32 of described eedle match, and the side of gathering sill 31 is provided with corresponding with locating convex block 21 position on guide-localization block 2 and that size is identical locating hole 33.
