The specific embodiment:

Below in conjunction with accompanying drawing the utility model is further described.

The following stated only is a better embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

See accompanying drawing 1-4, the utility model comprises: housing 10, color change head have two housings 10, and shown in Figure 1 is the internal structure schematic diagram behind the housing 10 outside taking away, and schlagblech 80 is installed in the housing 10, and schlagblech 80 1 ends and housing 10 are hinged; In the housing 10 controlling organization is installed, controlling organization promptly is the operating state that is used to control schlagblech 80, this controlling organization comprise transversely movable needle selection bar 20, can vertically move push away yarn bar 30, it is hinged to push away yarn bar 30 lower ends and schlagblech 80 middle parts; Wherein, needle selection bar 20 front ends have inlay card portion 22, push away yarn bar 30 tops and are hinged with spill spin block 40, and spill spin block 40 has clip-connecting rod 41, rotation splenium 43, and clip-connecting rod 41 can snap in inlay card portion 22;

Push away moving of yarn bar 30 and push away 70 drivings of yarn depression bar by needle selection bar 20 and outside, needle selection bar 20 can keep transverse movement, push away yarn bar 30 and can keep lengthwise movement, so when work needle selection bar 20 and push away yarn bar 30 and can guarantee to operate steadily, can not produce swing, it is more accurate to move, and can effectively reduce malfunction, more wear-resisting and can increase the service life.

Described needle selection bar 20 upper ends have needle selection compression part 21, compression part 26 resets; Needle selection bar 20 sides offer horizontal concrete chute 23, have first limited post 24 on the housing 10, and limited post 24 is positioned at horizontal concrete chute 23, but horizontal concrete chute 23 relative limit posts 24 laterally move; Needle selection bar 20 lower ends also are provided with support spring 25, and needle selection bar 20 is horizontal when mobile, is subjected to the influence of limited post 24, and needle selection bar 20 can remain level, can not produce swing, moves more stable; The position of needle selection compression part 21 can be decided according to specific design.

Described pushing away offers vertical chute 31 on the yarn bar 30, have second limited post 32, position limiting clamp 33 on the housing 10, push away yarn bar 30 and be sandwiched in the position limiting clamp 33, the similar comb of position limiting clamp 33 shapes, can separate and respectively push away yarn bar 30, and make held stationary when pushing away yarn bar 30 and vertically moving; Second limited post 32 is positioned at vertical chute 31, and vertically chute 31 can vertically move by relative second limited post 32.

Operation principle of the present utility model is as follows:

See Fig. 1, during reset mode, the clip-connecting rod 41 of spill spin block 40 blocks in the inlay card portion 22 of needle selection bar 20, and the depression bar 60 that resets props up the compression part 26 that resets of needle selection bar 20, and needle selection bar 20 keeps motionless;

See Fig. 3, when certain specific needle selection device 50 moves down, can push the needle selection compression part 21 of corresponding needle selection bar 20, reset simultaneously and move on the depression bar 60, releasing is fixing to the compression part 26 that resets, needle selection bar 20 moves right, and inlay card portion 22 driven rotary pieces 40 produce eccentric rotary when mobile, thereby the rotation splenium 43 of spill spin block 40 is positioned on the moving track that the outside pushes away yarn depression bar 70; See Fig. 4, push away yarn depression bar 70 and move down, and press down rotation splenium 43, finally make to push away yarn bar 30 and move down, thereby drive schlagblech 80 rotations, finish predetermined action.

Need to prove, the quantity of schlagblech 80 is consistent with pushing away yarn bar 30, the controlling organization of respective numbers all is installed in the housing 10, each controlling organization and schlagblech 80 be arranged in parallel respectively, schlagblech 80 generally has six, and controlling organization, spill spin block 40 also have six, is the simplification lines in the accompanying drawing, makes accompanying drawing keep clear, a controlling organization only is shown, a needle selection bar 20, one promptly only is shown among Fig. 3,4 pushes away yarn bar 30, a spill spin block 40; In addition, the position difference of the needle selection compression part 21 of each needle selection bar 20, shown in Figure 1 is the structure of needle selection compression part 21 mutual dislocation of six needle selection bars 20 when resetting fully.

Also have stop column 42 on the described spill spin block 40, stop column 42 was conflicted with pushing away yarn bar 30 when spill spin block 40 turned an angle, and can make spill spin block 40 rotation location, rather than produced 360 degree and rotate.

The utility model terminal with compact integral structure, internal mechanism operates steadily, and result of use is better.
