Further, described displacement space mechanism is made up of main shaft, elbow, bearing, annular balance staff, pendular ring, and main shaft end is flat design, has fixing hole above, coordinates with the adjustable ring on elbow, regulates setting angle, changes movement output.
Further, described bearing is the deep groove ball bearing be mounted opposite, and bearing cone is fixed on elbow lower end, and bearing outer ring is the annular groove of annular balance staff; During main axis, roller rolls in annular groove, drives annular balance staff to swing.
Further, described annular balance staff two ends are fixed on pendular ring, and junction is provided with sleeve, and two ends are provided with end cap.
Further, described pendular ring one end is axle, and one end is hole, and axle head is arranged on case, and nose end is connected with balance staff, and be interference fit between balance staff and pendular ring, there is boss one end, hole, ensures the intensity of mechanism.
Further, described balance staff is multidiameter, is above provided with gear wheel.
Further, described gear wheel and the pinion fits be arranged on pinion shaft, realize traverse and amplify, and the radius ratio changed between gear can regulate traverse amplification coefficient.
Further, described pinion shaft is provided with swing arm, is fixed by key between swing arm and pinion shaft, pinion shaft swing by swing arm transmission, drive slide block slide up and down on vertical pivot, drive eedle complete embroidery.
Displacement space of the present invention embroidery machine needle drive, by main shaft input power, realizes the swing of pendular ring by displacement space mechanism, drive balance staff to swing, outputed power, realize sliding up and down of eedle drive block by gears meshing.Needle bar stroke and movement velocity can regulate by regulating the radius of meshing gear to divide according to actual conditions.
