Description

Knitting tool

The present invention relates to be used to sew up the knitting tool of 2 braided fabrics, more particularly, is will be pulled in the coil that suture on this hook inserted, passed 2 overlapping braided fabrics with hook, the knitting tool that braided fabric is united by a seam each other.

When knit product is made in braiding by hand, when knitting a sweater, be after having woven predecessor's part, back body part, sleeve part respectively, each several part to be sewed up finished again for example.The method that these parts are sewed up has various, for example, suture is penetrated in the hole with the seam knitting needle of the same shape of sewing-needle the method that each coil of 2 braided fabrics is sewed up one by one.Perhaps, adopt crochet hook, draw with hook and hang suture and in the coil of 2 braided fabrics, insert, pass, the method for its stitching at the top of staight shank buckle.

But, the above-mentioned method of sewing up with the seam knitting needle, owing to coil ground of coil of braided fabric will be sewed up, so very time-consuming, in addition, sew up evenly in order to make, must note sutural tension degree in coil ground of a coil.Above-mentioned method with crochet hook, with crochet hook draw hang in the coil that suture inserts braided fabric after, when pulling out, hook tangles braided fabric sometimes and is not easy to pull out.

During the machinery braiding, make the ribbed knitting thing that is woven into front coil and purl loop or two-sided when all being the braided fabric etc. of positive pin, make the braided fabric of reverse side braiding earlier, only will take the part that backside loop changes surface coils into apart, coil ground of an one coil is woven again.This weaves used knitting tool again is known latch needles.This latch needles has the grip part of straight extension, from the shank of this grip part straight extension along its length, be located at the pin portion that the hook and the needle latch by corner bevelling of this shank front end constitute.The operator grasps the grip part, with pin portion insert taking apart of braided fabric part in, pick up with hook and to constitute the suture of braided fabric from body, line is pulled out braiding front coil.Because latch needles has needle latch, close at needle latch when braided fabric is pulled out, so hook can not tangle the line of braided fabric, do not produce the hanging wire problem in the above-mentioned stitching operation.But this latch needles has and is suitable for the braided fabric made of the machinery braiding shape from the making of body.That is, braided fabric remains on the braiding machine, and the operator needn't push braided fabric with the right hand of holding latch needles, and the right hand can carry out operation with latch needles to freely-movable.Latch needles has this hand can free-moving shape.In contrast in sewing up operation, hang over mode on the hook etc. for the direction, the line that insert, wear the needle section, the action of the hand in the operation is different fully, in addition, must arrest 2 braided fabric ground with two hands and carry out operation, so the movable distance of hand is restricted when pin portion is pulled out, therefore, latch needles is not suitable for sewing up operation.

, the objective of the invention is for this reason, a kind of knitting tool that is suitable for sewing up operation is provided in order to solve the aforesaid drawbacks.

To achieve these goals, knitting tool of the present invention, grasp the grip part, the pin portion that will have needle latch and hook inserts, passes in the coil of braided fabric, needle latch is swung between the release position of the closed position of hook and hook, suture by hook strip simultaneously several braided fabrics are sewed up each other; It is characterized in that, has the shank that an end is installed on the above-mentioned grip part, is provided with above-mentioned pin portion on the other end integratedly, this shank has sweep and straight line portion, when the operator holds the grip part, this sweep is towards leaving the operator party to bending, above-mentioned straight line portion from sweep towards the straight extension of above-mentioned pin portion.
