     In the subject invention, on top of the fixed block 12 in the housing 1 is a slide mechanism 3, said slide mechanism comprises a first slide block 31, one side at one end of said first slide block is extending upward to form a protruding piece 311, on the protruding piece 311 is a protruding post 312, while on the other side is a through air channel 313, said through air channel 313 communicates with the air inlet 14 on the fixed block 12, over said air channel 313 is also a washer 314, furthermore, on top of the first slide block 31 is a middle plate 32, the size of said middle plate 32 is slightly smaller than the size of the first slide block 31, and, on top of the middle plate 32 is a second slide block 33, on a position at one side of said second slide block 33 opposite to the protruding piece 311 on the first slide block 31 is also an extended protruding piece 331, on the protruding piece 331 is a protruding post 332, said two protruding posts 312 and 332 are kept at a specified distance, in this example of embodiment, the other end of the second slide block 33 is dovetailed with a pressing block 34, said pressing block 34 corresponds to the air channel 313 on the first slide block 31, the top side of the pressing block 34 is pressed by the bolt 16 that is tightened on top of the housing 1 and pressing downward, and a clearance is reserved between it and the first slide block 31. 
     In the subject invention, there is a block piece 4, said block piece 4 is made of ceramic, it is inserted in the clearance between the pressing block 34 and the first slide block 31, it is on the same level with the middle plate 32, on said block piece 4 is a V-channel 41, on the V-channel 41 is a through air hole 42, said air hole 42 communicates with the air channel 313 on the first slide block 31. In this example of embodiment, said air hole 42 is perpendicular to the V-channel 41, or as shown in FIG. 3, said air hole 42&#39; may be inclined at an angle to communicate with the V-channel 41, by the angle of inclination, the yarn blowing effect may be enhanced; so designed that, when the textile yarn is hanged onto the V-channel 41 on the block piece 4, compressed air is delivered from the air inlet 14 on the fixed block 12 through the air channel 313 on the first slide block 31, to the air hole 42 on the block piece 4, to blow onto the yarns. 
     In the subject invention, between the first slide block 31 and the second slide block 33 is a driving unit 5, said driving unit 5 comprises a hollow shaft sleeve 51, said hollow shaft sleeve 51 is fitted onto a joining rod 52, its two ends are each respectively clamped by a C-clamp 53 onto the joining rod 52, while one end of the joining rod 52 is inserted into the joining hole 321 on the middle plate 32, and the other end extends out of the housing 1 to be fixed with a turning knob 54, on said turning knob 54 is a vent 541 that serves as a marking to determine whether the first and the second slide blocks 31 and 33 have moved or not, furthermore, on the outside of said shaft sleeve 51 is a spiral shaped slide channel 511, the protruding post 312 and 332 respectively located on the first and the second slide blocks 31 and 33 are accommodated in the two ends of said slide channel 511, so when the turning knob 54 is turned, the protruding posts 312 and 332 on the first slide block 31 and the second slide block 33 will be moved with the movement of the slide channel 511, then the first and the second slide blocks 31 and 33 will move separately in opposite directions. 
     Please refer to FIG. 2, to perform the yarn hanging operation, the yarns are hanged onto the V-channel 41 on the block piece 4, and since the opening of the housing 1 is not completely covered by the cover 2, and the pressing block 34 has not yet moved to above the block piece 4, so, the block piece 4 will be exposed on the outside, and the air channel 313 on the first slide block 31 has not yet communicated with the air inlet 14 on the fixed block 12, so the compressed air could not flow onto the block piece 4. 
     Please refer to FIGS. 1 and 4, to blow compressed air onto the yarns on the block piece 4, turn the turning knob 54 to rotate the shaft sleeve 51 on the joining rod 52, so the protruding posts 312 and 332 on the first slide block 31 and the second slide block 33 will move along the slide channel 511, since the first and the second slide blocks 31 and 33 are respectively located at two ends of the slide channel 511, the first and the second slide blocks 31 and 33 will move in opposite directions, then, since the first and the second slide blocks 31 and 33 move in opposite directions, the first slide block 31 will move to the right, so the air channel 313 on the first slide block will communicate with the air inlet 14 on the fixed block 12 and with the air hole 42 on the block piece 4, meanwhile, the second slide block 33 will move to the left, so the pressing block 34 at the end of the second slide block 33 will be positioned above the block piece 4, obstructing the air hole 42, then the compressed air is blown into the air inlet 14 on the fixed block 12, through the air channel 313 on the first slide block 31, and into the air hole 42 in the block piece 4, and onto the yarns, without leaking to the outside, thus, the textile yarn blowing operation is accomplished. 
     To prevent air leak at the air inlet 14, the air channel 313 and the air hole 42 in the subject invention, in addition to the washers 15 and 314 fitted respectively onto air inlet 14 and the air channel 313, the bolt 16 is screwed to extend downward to push on the pressing block 34, so the block piece 4 and the first slide block 31 can be pressed tightly together, but if the bolt 16 is directly pushed against the second slide block 33, it will cause inclination on one end of the second slide block 33, therefore, the end of the second slide block 33 is dovetailed with a pressing block 34, so the bolt 16 is screwed and extending down to push against the pressing block 34, the second slide block 33 will slide smoothly without any inclination. 
     Please refer to FIGS. 5 and 6 which illustrates the second example of embodiment of the subject invention, wherein, at the sides of said first slide block 31 and the second slide block 33, away from the block piece 4, are respectively the openings 61 and 62 that are aligned to each other, and on the top side of the housing 1 corresponding to the positions of the openings 61 and 62 is another hole 63, besides, said driving unit 6 includes a joining rod 64, said joining rod 64 penetrates the hole 63 on the housing and through the openings 61 and 62 on the first and the second slide blocks 31 and 33, said joining rod 64 extending out of the top of the housing 1 is fitted to a turning knob 65, at the openings 61 and 62 of the two slide blocks 31 and 33 there are respectively the eccentric cams 66 and 67, said two eccentric cams 66 and 67 are positioned onto the joining rod 64 by C-clamps 68 from the outsides nearer to the two ends, the lobes 661 and 671 of the two eccentric cams 66 and 67 are arranged in opposite directions, while the construction of other components remain the same as the first example of embodiment. 
     Please refer to FIG. 7, to blow compressed air onto the yarns on the block piece 4, turn the turning knob 64 to rotate the two eccentric cams 66 and 67 on the joining rod 64, then, the lobes 661 and 671 of the two eccentric cams 66 and 67 will push the two slide blocks 31 and 33 to move, since the lobes 661 and 671 of the two eccentric cams 66 and 67 are arranged in opposite directions, the first and the second slide blocks 31 and 33 will also move in opposite directions, the first slide block 31 will move to the right, so the air channel 313 on the first slide block 31 will communicate respectively with the air inlet 14 on the fixed block 12 and the air hole 42 on the block piece 4, meanwhile, the second slide block 33 will move to the left, so the pressing block 34 at one end of the second slide block 33 will be positioned above the block piece 4, obstructing the air hole 42, so compressed air enters from the air inlet 14 on the fixed block 12, through the air channel 313 on the first slide block 31, into the air hole 42 on the block piece 4, and onto the yarns, without any air leak, thus the textile yarns blowing operation is accomplished. 
     Summing up, by means of the construction of the subject invention, the operator will not have to disassemble the components when he or she is operating the yarn hanging operation or cleaning the block piece 4. All the operator has to do is perform the yarn hanging or cleaning job directly on the block piece 4, so it is quite convenient in its operation. The unsophisticated construction of the subject invention is more simplified than the previous application filed by the subject inventor. With easy operation in production and assembling processes, it will be able to significantly save the production costs. Therefore, it is indeed an ideal construction.
