Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the partial enlarged drawing of Fig. 1;

Fig. 3 is that of the present utility model another implemented state diagram.

The specific embodiment

As Fig. 1, shown in Figure 2, needle selection device of the present utility model comprises needle selection device seat 1, cover plate 2, electrical equipment base plate 8, needle selection blade pressuring plate 4 is installed on the needle selection device seat 1, electrical equipment base plate 8 is packed in the upper end of needle selection device seat 1, needle selection blade pressuring plate 4 is installed on the lower surface of needle selection device seat 1, two cover plates 2 is packed on needle selection device seat 1 two sides, the one side of the one side of magnetic receiver 3 and cover plate 2 is linked to be an integral body with seccotine is affixed, by needle selection device seat 1, cover plate 2, electrical equipment base plate 8, needle selection blade pressuring plate 4 is formed housing of the present utility model, in needle selection device seat 1, divide two row spaces respectively to be provided with quadruplet needle selection unit, be installed on respectively on two magnetic receivers 3, dress quadruplet needle selection unit on every magnetic receiver 3, totally 8 overlap, every cover needle selection unit comprises an axle sleeve 9, a spring 10, an iron core 11, a coil rack 12, one group of o 13, axle sleeve 9 is contained in magnetic receiver 3 one and turns up in the slot mesh on the end, o 13 is wrapped on the coil rack 12, spring 10 and coil rack 12 are contained on the iron core 11, iron core 11 1 ends are contained on the axle sleeve 9, the other end is contained on the magnetic receiver 3, four needle selection cutter heads 5, four needle selection cutter heads 6,8 backing pin shafts 7, upper end at the needle selection cutter head is fitted with magnet, the magnet of needle selection cutter head 5 is installed in the right side, the magnet of needle selection cutter head 6 is installed in the left side, 8 needle selection cutter head removable mountings are on bearing pin 7, the needle selection cutter head can rotate along bearing pin 7,8 backing pin shafts, 7 two ends are packed on needle selection device seat 1 two sides, needle selection blade pressuring plate 4 two ends are turned up partly and are packed on the needle selection device seat 1, have 8 elongated slots on the needle selection blade pressuring plate 4,8 needle selection cutter head heads expose needle selection blade pressuring plate 4 bottoms.
