The specific embodiment
Detailed description of relevant the utility model and technology contents now just cooperate graphic being described as follows:
Please consult " Fig. 1 " simultaneously and reach shown in " Fig. 2 ", be described three horizontal cylindrical sewing machine outward appearances and lower cutter device schematic diagram.This lower cutter device 1 is sewing platform 101 belows of being located at Sewing machines 100, has a chassis 2, this chassis 2 is arranged with a stopper slot 21, be slidingly equipped with a swing base 5 in this stopper slot 21, be slidingly equipped with an operating bar 4 on this swing base 5, these operating bar 4 one ends offer one and activate guide groove 41, and are equipped with one first restriction rail 42 and one second restriction rail 43, these operating bar 4 other ends then are installed with a cutter 8, and this cutter 8 has the blade 81 of a sword towards this chassis 2; Wherein this chassis 2 is boundary with this stopper slot 21, this chassis 2 is marked off than the large tracts of land side and than the small size side, though this is than the large tracts of land side and than the small size side symbology is not arranged in graphic, all can be clear that the difference of its area size in " Fig. 2 "; And in this chassis 2 larger areas, one side respectively axle establish an end of one first linking swing arm 6 and one second linking swing arm 7, the other end of this first linking swing arm 6 and this second linking swing arm 7 then respectively axle be provided with one and slip the first spindle guide spare 61 and the second spindle guide spare 71 that is arranged in this first restriction rail 42 and this second restriction rail 43, and this first spindle guide spare 61 also is coupling with this swing base 5 respectively with this second spindle guide spare 71; In addition spool establish one in these 2 the same sides, chassis and between this first linking swing arm 6 and this second linking swing arm 7 and slip the actuating swing arm 3 that is inserted in this actuating guide groove 41, and this actuating swing arm 3 is to have the actuation ends of an arcuation 31, and 31 of this actuation ends are slipped and are inserted in this actuating guide groove 41; In addition, this swing base 5 is provided with a lean against part 51, and this chassis 2 sets firmly an end of an elastic parts 23 on the side than small size, the other end of this elastic parts 23 then connects establishes the pressing block 22 that a normality is suppressed this lean against part 51, and is installed with a confinement block 24 that limits these pressing block 22 displacements on this chassis 2 in nearly these pressing block 22 places; In addition, above-mentioned elastic parts 23 is a spring.
Please consult " Fig. 2 " simultaneously in addition and reach shown in " Fig. 3-1～3-3 ", be described three horizontal cylindrical sewing machine lower cutter devices and illustrative view thereof.When not having this lower cutter device 1 of activation (shown in " Fig. 3-1 "), this operating bar 4 has most area to be positioned at this stopper slot 21 with this swing base 5, and note because this pressing block 22 is subjected to the drawing of this elastic parts 23, so this lean against part 51 of normality compacting, make this operating bar 4, this swing base 5 and this cutter 8 be comparatively heeling condition, and notice that this pressing block 22 and this confinement block 24 are released state at this moment; When activating this lower cutter device 1 at the beginning the time (shown in " Fig. 3-2 "), this actuating swing arm 3 is stressed and the axle commentaries on classics, make this actuation ends 31 drive this operating bar 4 and make this operating bar 4, this swing base 5 and this cutter 8 produce swing with pining down of this second spindle guide spare 71 because of being subjected to this first spindle guide spare 61, this lean against part 51 promptly compressed this pressing block 22 and made this pressing block 22 be abutting orientation with this confinement block 24 this moment, and made this operating bar 4, this swing base 5 and this cutter 8 be comparatively level; Then this of this lower cutter device 1 activates the promptly then lasting application of force axle of swing arm 3 changes (shown in " Fig. 3-3 "), owing to compressing this pressing block 22, this lean against part 51 makes this pressing block 22 and this confinement block 24 be abutting orientation making this swing base 5 be slack, at this moment this actuation ends this operating bar 4 of 31 sustainable drives and make this operating bar 4 and this cutter 8 continue to be forward the feed state; Next this actuation ends 31 promptly can drive this operating bar 4 and is above-mentioned opposite step start, can finish thread cutting action once in this way, and can reach the position of adjusting easily after this lower cutter device 1 feed, and make the purpose of finishing thread cutting action after this lower cutter device 1 feed really.
Being preferred embodiment of the present utility model only in sum, is not the practical range that is used for limiting the utility model.Be all, all should be the technology category of the utility model according to holding the equivalence variation and modification of doing within the utility model claim.
