The specific embodiment
To combine below accompanying drawing to the utility model make detailed introduction: Fig. 1, shown in 2, the utility model is mainly by casing ontology and mainly by thorn cloth hook line mechanism, pin width of cloth mechanism, the internal mechanism that needle gage mechanism and cloth feeding mechanism constitute is formed.Described casing ontology comprises: the peripheral covering of plastics, and protecgulum 1, bonnet 2 etc., this casing ontology is provided with: backstitch button 3, needle plate body 4, auxiliary box 5, style knob 6, lampshade 7 etc.
Shown in Figure 3, described Ci Bu mechanism is mainly linked to each other with last axle 9 through belt pulley 12 by alternating current generator 17, and axle 9 is connected with shank with needle bar connecting rod 28 and drives its realization that can move up and down and sting cloth and move through the axle cranks 29 of going up of needle bar this on; The described axle 9 of going up also is connected with a big connecting rod 11, and this big connecting rod 11 is connected with a lower shaft 19 through a lower shaft crank 15, and said lower shaft 19 cooperates through half gear 21 and with a bronze medal gear 22 and is connected with a big still.
The concrete course of work is: drive belt pulleys 12 by alternating current generator 17 and drive and go up axle 9 and rotate, the rotation of last axle 9 drives shanks 25 and moves up and down to accomplish and sting cloth through go up axle crank 29 and the needle bar connecting rod 28 of needle bar.In the time of thorn cloth,,, big connecting rod 11 rotations drive lower shaft 19 rotations thereby driving lower shaft crank 15 through rotation drive big connecting rod 11 rotations of last axle 9,21 rotations of lower shaft 19 drives half gear, and half gear 21 cooperates the rotation that drives big still with copper gear 22.
Shown in Figure 4, described pin width of cloth mechanism mainly comprises: go up axle 9 the and amplitude driving bar 27 on being placed in pin width of cloth drive rod support 8 and shank 25 on the needle bar bracket 26 links to each other through a flower mould 30 by said, and make the wobbling action about these shank 25 works.The described axle 9 rotation drive flower moulds 30 of going up rotatablely move, and the rotation of Hua Mo 30 converts swinging of shank 25 to through pin width of cloth drive rod support 8 and pin width of cloth drive rod 27, needle bar bracket 26.
