Detailed description of the invention

See figures.1.and.2 the utility model is described further.

A kind of yarn probe assembly as depicted in figs. 1 and 2, comprise seat board 1, on seat board 1, be provided with photo-electric yarn detector 2, on described photo-electric yarn detector 2, be provided with Wire channel in building 3, photo-electric yarn detector 2 both sides are provided with installs iron plate 4, installs on iron plate 4 and offers the U-shaped opening 5 that is less than Wire channel in building 3, installs in iron plate 4 and is plugged with the insert-connecting plate 6 matching with U-shaped opening 5, on insert-connecting plate 6, be provided with U-lag 7, on the sidewall of described deep-slotted chip breaker 9, be provided with the stable piece 8 arranging with yarn gap. Deep-slotted chip breaker 9 is by arranging a stable piece 8 insert-connecting plate 6 is interior, can reduce the space that yarn can be shaken in the time of transmission, stability when thereby the excessive jitter that reduces yarn increases yarn transmission, and then make the infrared pulse producing in yarn probe more stable, increase the spy silk precision of yarn probe. Wherein, stablize piece 8 and be formed in one with insert-connecting plate 6, can accelerate the production efficiency of this insert-connecting plate 6. The material of stablizing piece 8 and insert-connecting plate 6 is set to plastics. Because plastics have stronger plasticity, can make the sidewall of deep-slotted chip breaker 9 and bottom surface can keep smooth, reduce yarn when shake and cause that with deep-slotted chip breaker 9 sidewall friction yarn fluffs, increase the quality of yarn. Plastic material low price, can reduce production costs.

As Fig. 2, described stable piece 8 is the deep-slotted chip breaker 9 caving inward towards the end face of yarn one side. The shake space that is arranged so that yarn when transmission of deep-slotted chip breaker 9 is for circular, yarn is located in the middle of this shake space, its small shake of carrying out can be carried out to all directions, and the existence of avoiding stablizing piece 8 suppresses the shake of yarn and causes the false alarm phenomenon of yarn probe. This concave profile can also avoid yarn to deviate from this shake space.
