Fig. 6 be along with Fig. 3 in the cutaway view got of identical section, shown needle jack with the bend that keeps left and will move right;
Fig. 7 is the schematic diagram of needle jack with respect to the arrangement examples of the knitting needle on the circular cyiinder knitting machine.
The specific embodiment
With reference to the accompanying drawing of being quoted, totally the needle jack according to the present invention by Reference numeral 1 expression forms by punching press and bending flat steel part.This needle jack has shank 12, and this shank is provided with the heel 3 of lower edge and totally by the top of the activity of Reference numeral 4 expressions.
See that from the side this movable top 4 comprises bend 5, this bend is outstanding from the edge of shank, and heel 3 points to this edge.
This bend 5 is made of the step 8 of first curved portion 6, mid portion 7 and rounding.
Mid portion 7 is with respect to the plane of shank 2 (as shown in Figure 2) or be diverted a side left to the right respectively, finishes with straight substantially second portion 9 through the step 8 of rounding.
The plane parallel of second portion 9 and shank 2, and with respect to this planar offset.
Second portion 9 passes through the 3rd sloping portion 10 that in the opposite direction tilts with respect to mid portion 7 and finishes with point 11.
Therefore, with respect to the plane of shank 2, point 11 is outstanding on the opposition side that is diverted a side with respect to mid portion 7.
According to a concrete aspect of the present invention, by milling machine, grinding machine or other equipment or even in the second portion 9 manual first oblique portions 12 that provide that process.The first oblique portion 12 allows needle jack 1 can not interfere the adjacent needle jack that has same flexure portion and be in off-position in the decline stage.
The 3rd sloping portion 10 also has the second oblique portion 13, and it has similar function with the first oblique portion 12.
Another feature of the present invention is made up of the oblique portion 14 of the 3rd grinding, and it is positioned at and is applicable to first curved portion, 6 places that weaken needle jack, stays the crooked spaces that are used for because curved portion 6 is relatively thinner with the breach place at the cylinder that slides for needle jack more.
The shank 8 of rounding and second portion 9 be common to be formed enough deeply and as the groove 15 of needle latch opening device.
When needle jack was loaded with maille and be arranged to be used for want the knitting needle of transfer stitch, this knitting needle tended to rise, and if needle latch close mistakenly, it is opened and reduces with the yarn by coil itself.
Enough dark groove allows the braiding yarn with maille to be arranged in to help as on the position of knitting needle opening device.
According to another feature of the present invention, to carry out induction tempering and handle to obtain the point harder than needle jack body, this needle jack body has passed through temper but the hardness deficiency.
