Description

The present invention relates to knitting needles used for knitting, and more particularly to knitting needles used in flat knitting machines.

A front needle bed and a rear needle bed are symmetrically installed in the flat knitting machine, needle grooves corresponding one to one are provided in the front and back needle beds, respectively, and knitting needles are placed in the needle grooves, respectively. As shown in FIGS. 43 and 44, the knitting needle generally has a hook A1, a latch A2 and a handle A3, the latch A2 is provided on the rear side of the hook A1 and can be rotated to close the hook A1, and the handle A3 is composed of a needle bar A31 and a needle body A32 which are sequentially provided at the rear part of the hook. A concave first transfer portion A4 is formed by the connection between the front side of the needle bar and the rear side of the needle bar.

When performing general knitting, the knitting needle moves up and down along the needle groove to move the stitch on the knitting needle with respect to the knitting needle, and when it moves to a position corresponding to the latch, the latch is driven to rotate, and the latch is rotated. or open the latch.

When performing transfer knitting, the two knitting needles in the corresponding needle grooves on the front and back needle beds should cooperate with each other to realize the transfer, for example, the needle grooves originally located in the front needle bed. It is necessary to move the stitch on the knitting needle to the corresponding knitting needle on the back needle bed, so that the corresponding knitting needle on the back knitting needle bed is inserted into the stitch of the knitting needle on the front needle bed. A spring plate A5 provided with a protrusion A51 is provided on one side of the handle of the knitting needle, and the stitch is spread by the protrusion by relatively moving the stitch to the protrusion of the spring plate, so that the corresponding knitting needle can be inserted from the spread stitch.

A spring plate on a conventional knitting needle is provided in a concave groove on one side of the handle, and the spring plate is basically bent into one trapezoidal projection A51 as a whole according to the length direction of the knitting needle, as shown in FIG. As shown, the inner cavity of the protrusion A51 forms a hook insertion groove A511, the rear side of the protrusion A51 is a connecting end A512 to be connected to the groove bottom surface of the groove, and the front side of the protrusion is attached to the handle. The spring plate straddles the needle bar A31 and the needle body A32 and has a wide segment and a narrow segment, the part corresponding to the needle bar A32 being wider than the part corresponding to the needle bar A31. The joining point of the two segments forms a concave second transfer portion A52, which corresponds to the position of the first transfer portion A4.

When performing transfer knitting, the stitches on the knitting needle pass through the front slope A51b of the projection and slide to positions corresponding to the first transfer portion and the second transfer portion on the top end surface A51a of the projection A51, and spread. be done. Therefore, the projection must be higher than the side surface of the corresponding handle, and at the same time, the knitting needle corresponding to the needle is inserted into the hook insertion groove A511 from below the hook insertion groove and hooked on the knitting needle. The knitting needles on the back needle bed are inserted into the stitches, and during this time the knitting needles on the back needle bed move in the longitudinal direction with respect to the knitting needles on the front needle bed. Therefore, the hook insertion groove needs to be sufficiently long so as to provide a suitable length of motion space, and the stitch to be spread out can be more easily slid from the front slope A51b to the top end surface A51a of the projection. In order to realize the spread, the slope of the front slope should be as flat as possible, i.e. the slope should be small. , the gradient of the rear slope A51c must also be as small as possible. Thus, the protruding portion is too long, has low rigidity, and is easily deformed when the stitch is pulled obliquely or laterally, which is disadvantageous for the insertion of the knitting needle, thereby reducing the insertion reliability. If the gradient of the slope is large, it is difficult for the stitch to slide from the rear slope of the protrusion to the top end surface of the protrusion, and a phenomenon in which the stitch is "grabbed" will occur. In order to improve the rigidity of the spring plate and avoid the "thread picking" phenomenon, the protrusion part should be high enough, and when transferring the stitches, the stitches will hang on the protrusions when returning to the lower part of the needle bar. The stitches are spread wider and cannot be adapted to relatively high density knitting.

The knitting needle having the spring plate in the above prior art has the following problems. That is, the protrusion on the spring plate is always higher than the corresponding side surface of the knitting needle, and the space occupied by the knitting needle is large. In this way, the processing of the billet and the installation process of the throat plate are complicated, the production efficiency is low, which increases the cost, and the groove is provided. Steel billets cannot produce high-gauge throat plates and are not suitable for higher-gauge knitting.

In addition, conventional knitting needles cannot ensure that the latch receiving the transfer knitting needle is opened by the lower end of the hook insertion groove of the knitting needle cooperating with it or the lower end of the handle when transferring. When the latches of the corresponding knitting needles are opened by the transfer stitches and the latches of the corresponding knitting needles are opened by the transfer stitches, the tips of the latches are always thrust into the knitted wire made of twisted yarn, causing the phenomenon of "monofilament", thereby causing defects in the fabric. end up

SUMMARY OF THE INVENTION It is an object of the present invention to overcome the deficiencies of the prior art and to provide a knitting needle. The technical proposal is as follows.

The knitting needles are provided in needle grooves on the front and rear needle beds of the flat knitting machine and can cooperate with knitting needles in corresponding needle grooves on the back needle bed or the front needle bed, and
hook and
a latch behind the hook and capable of rotating to close the hook;
a handle consisting of a needle bar successively provided at the rear of the hook and a needle body wider than the needle bar;
a concave first transfer portion formed by a connecting portion between the needle bar and the needle body;
a groove provided on one side of the handle;
A concave second transfer part is provided, and the front part is bent to protrude outward along the length of the handle, and the rear part is connected to the groove bottom surface of the groove to form a connection end. a springboard;
a hook insertion groove formed by an internal cavity of the protrusion;
The spring plate is further provided with a deformation surface located between the rear side of the protrusion and the front side of the connection end, and the deformation surface and the protrusion are not exposed from the groove, or there is a portion exposed from the groove. The portion elastically pressed into the groove by the needle groove or exposed from the groove is located in the groove provided on the corresponding side of the needle groove, and corresponds to the knitting needle in the needle groove during transfer knitting. The hook is inserted between the spring plate and the handle through the hook insertion groove, and the deformation surface is elastically deformed to drive the projections to expand outward, thereby forming the first transfer portion and the second stitch. Spread the stitches that are hung on the transfer part.

In the knitting needle of the present invention, the deformation surface is provided on the spring plate, and elastic deformation rotating outward is generated on the deformation surface by inserting the corresponding knitting needle between the spring plate and the handle during transfer knitting. , the protrusions are driven to spread outward, thereby spreading the stitches applied to the first transfer portion and the second transfer portion. This can achieve a widening effect and thereby reduce the length of the projection, increase the rigidity of the projection, and improve the stability of the hook insertion groove formed by the internal cavity of the projection. At the same time, by setting the structure of both the deformation surface and the projection, both can be accommodated in the concave groove on one side of the handle when both are in the natural state or when pressed by the needle groove, i.e. the entire spring plate is located in the needle groove and has no part exposed from the concave groove, reducing the width of the entire knitting needle, thereby adapting to high-density knitting of the flat knitting machine and placing the knitting needle in the needle groove To facilitate the placement of more knitting needles along the lateral direction on the throat plate, both or one of them has a portion exposed from the recessed groove to accommodate different knitting needs. Alternatively, the portion exposed from the recessed groove may be located in the recessed groove provided on the corresponding side of the needle groove.

Further technical solutions of the present invention are as follows.

The deformation surface is a bending surface that is bent outward, and includes at least one outer end that is higher than the lower end of the protrusion and is positioned in front of the connecting end by bending, the front side of the outer end, and the rear side of the protrusion. and a slanted arrangement portion positioned between the deformation surface and the groove bottom surface of the groove to have a space between the deformation surface and the groove bottom surface of the groove, which is useful for elastic deformation of the deformation surface.

The deformation surface is a plane, and may be a plane bonded to the groove bottom surface of the groove, or may have a certain included angle with the groove bottom surface.

The depth of the groove formed between the top end surface and the bottom end surface of the hook insertion groove is smaller than the thickness of the hook, and a needle groove guide for facilitating insertion of the hook is provided at the lower end of the hook insertion groove. and/or the tip of the hook is provided with a hook guide to facilitate entry into the hook insertion groove. By reducing the depth of the groove, i.e. reducing the height of the projection, the rigidity of the projection can be further increased, and when the depth of the groove is less than the thickness of the hook, the needle groove guide or/and The hook guiding part ensures smooth introduction of the hook into the hook insertion groove, and the insertion of the hook into the hook insertion groove and having a thickness greater than the depth of the groove increases the elasticity of the deformation surface of the spring plate. Rotating the deformation outward drives the projections to expand outward.

The lower end of the spring plate protrudes downward corresponding to the front position of the second transfer portion to form a latch opening portion, which is used to open the latch of the knitting needle that has entered the hook insertion groove. To avoid the "monofilament" phenomenon that can occur when the latch is opened by the movement of the stitch relative to the needle during transfer knitting.

The needle groove guide portion is provided on the bottom surface of the groove, is located at the lower end of the hook insertion groove, and is a slope inclined rearward, so that the hook is easily inserted into the lower end opening of the hook insertion groove. It has a bell mouth shape that makes it easy to smoothly guide the hook to the hook insertion groove.

The tip of the knitting needle has an arc shape or trapezoid that gradually widens, and the narrowest part of the tip is smaller than the depth of the groove, so that the tip of the hook can be easily and smoothly inserted into the hook insertion groove. .

The deformation surface and the projection correspond to the positions of the front portion of the needle body and the rear portion of the needle bar, respectively, and the front side of the deformation surface extends upward along the width direction from the rear side of the projection to form the second transfer portion. It is positioned at the connection point between the deformation surface and the projection. This makes it possible to reduce the length of the protrusions as much as possible, increase the rigidity of the protrusions, and elastically deform the deformation surface to create a gap between the groove bottom surface and the correspondingly cooperating knitting needle to move. This widens the movement space that is narrowed due to the reduction in the length of the protrusions, so that the stitches do not hang on the protrusions when returning to the lower part of the needle bar during transfer knitting. It is hung at positions corresponding to the first transfer part and the second transfer part to spread the transferred stitches so that they are not too large, especially suitable for high-density knitting, uniform knitting density, and improving knitting quality. Secured.

The length of the deformation surface is greater than the length of the projection. Utilizing the deformation principle in which the deformation of the deformation surface rotates outward, the length of the deformation surface is increased to increase the amount of elastic deformation, thereby realizing a higher effect of widening.

The invention will now be further described by means of examples with reference to the drawings. Examples 1 to 6 correspond to the technical solutions proposed in the first priority application (January 21, 2020) of the present application, and the technical solution is the earliest application (January 14, 2020). is the same as the solution proposed in , the deformed surface and protrusions on the spring plate sink into the recessed groove on one side of the handle and do not protrude from the recessed groove (or the corresponding side surface of the handle) ) structure. Examples 7 to 11 correspond to technical proposals proposed in the second priority application (August 10, 2020) and added to the first application, and the deformed surfaces and protrusions on the spring plate are concave. Although it may be exposed from the groove, it is a structure in which the exposed portion may be pressed into the concave groove by the needle groove. Example 12 corresponds to a technical solution proposed in this application (third priority application) and added to the solutions proposed in the first application and the second priority application, The structure is such that the deformation surface and the protrusion on the spring plate may be exposed from the recessed groove, and the exposed portion may be placed in the recessed groove provided on the corresponding side of the needle groove.

As shown in FIG. 1, the knitting needles are provided in needle grooves corresponding to the front needle bed 91 and the rear needle bed 92 of the flat knitting machine, and the knitting needle 1 is in any one of the needle grooves 911 of the front needle bed 91. In this case, there is a knitting needle 2 in a needle groove 921 corresponding to the needle groove 911 on the back needle bed 92, and the knitting needle 1 and the knitting needle 2 have completely the same structure. should work in concert with each other. In each of the following examples, the structure of the knitting needle of the present invention will be described using the knitting needle 1 as an example.

Example 1
As shown in FIGS. 2 and 3, the knitting needle 1 has a hook 11, a latch 12, and a handle 13 consisting of a needle bar 131 and a needle body 132, both of which are found in conventional knitting needles. wider than 131 and both form a concave first transfer portion 15 at the connection point. A groove 133 is provided on one side of the handle of the knitting needle 1 , and the groove 133 spans corresponding sides of the needle bar 131 and the needle body 132 , and the spring plate 14 is accommodated in the groove 133 . The spring plate 14 has a wide portion and a narrow portion, and a concave second transfer portion 143 is formed at the connection point between the wide portion and the narrow portion. corresponds to the position of part 15; In this embodiment, the deformation surface and the protrusion correspond to the positions of the front part of the needle body and the rear part of the needle bar, respectively, and the front side of the deformation surface extends upward along the width direction from the rear side of the protrusion, and the second stitch The transfer portion is positioned at the connecting portion between the deformation surface and the projection. In this way, when the knitting needles for the transfer knitting are completely extended from the needle groove (see FIGS. 8 and 9), the stitch X is applied to the positions corresponding to the first transfer portion and the second transfer portion. The stitches that are put on the needle bar during transfer knitting are adapted to the density of the original stitches so that they are not too large, and are particularly suitable for high-density knitting.

The lower end of the spring plate of this embodiment is in a flat state without protrusions, higher than the lower edge of the handle, and connected to the groove bottom 1331 of the groove 133 by the rear portion, generally by welding. , thereby forming a connecting end 145, the front portion of which is bent outward along the length of the handle to the protrusion 141, the front lower end of the protrusion being bonded to the groove bottom surface 1331 of the recessed groove; The internal cavity of the projection 141 forms a hook insertion groove 1411. As shown in FIG.

The present invention further provides a deformation surface 142 between the rear side of the projection and the front side of the connection end, and the elastic deformation of the deformation surface drives the projection to widen outward, thereby realizing the purpose of widening. , in order to expand the protrusions outward to the required width, the deformation surface of this embodiment is designed as follows. That is, the deformation surface 142 is formed by one triangular fold at the outer edge of one fold point (multiple triangular folds may form the outer edge 1421 and the slanted portion 1422 of multiple fold points, if desired). A portion 1421 and an inclined arrangement portion 1422 are formed, the outer end portion 1421 being higher than the lower end of the projection 141 and positioned in front of the connection end 145 , and the inclined arrangement portion 1422 being positioned in front of the outer end portion 1421 It is a portion located between the rear side of the projection and inclined from the outside to the inside, forming a space between the deformation surface 142 and the groove bottom surface 1331 of the groove. Neither the top end surface 14111 of the projection 141 nor the outermost end, i.e. the outer end 1421, of the deformation surface 142 protrude (are not exposed) from the outermost side of one side of the handle, i.e. protrude the most on the corresponding side of the handle. no higher than the sides.

As shown in FIG. 4, the depth h of the groove formed between the inside of the top end surface 14111 of the hook insertion groove 1411 and the bottom end surface (that is, the groove bottom surface 1331) is is less than the thickness of the hook. At the lower end of the hook insertion groove 1411, there is provided a needle groove guide portion for facilitating the insertion of the hook. , and the lower end opening of the hook insertion groove is shaped like a bell mouth. The tip of the hook of the knitting needle, as shown in FIG. The hook guide portion facilitates insertion of the tip of the hook into the hook insertion groove. During transfer knitting, the corresponding knitting needle (eg, knitting needle 2) cooperating with the knitting needle (eg, knitting needle 1) currently having a stitch is recessed in the deformation surface by passing through the hook insertion groove into which the knitting needle 1 is inserted. The purpose of widening the stitches on the knitting needle 1 is achieved by causing the grooves to elastically deform and rotate with respect to the groove bottom surface and driving the projections to widen them outward.

As shown in FIGS. 6 and 7, when performing transfer knitting, the knitting needle 1 having the stitch to be transferred moves upward along the needle groove, and the stitch X thereon moves along the first transfer portion 15 and the first transfer portion 15. Relative movement is performed to the position of the second transfer portion. At this time, the corresponding knitting needle 2 is inserted into the hook insertion groove 1411 by the needle groove guide portion from the lower portion of the projection 141 on the knitting needle 1, and the hook portion of the knitting needle 2 is rotated outward by deforming the deformation surface. , the protrusions are driven to spread outward, and the stitches X are spread. At this time, the latch 22 on the knitting needle 2 may be opened when the lower end of the hook insertion groove 1411 is touched, or may not be opened without the touch. If the latch is opened, you may refer to Example 3 below, and if the latch is not opened, the knitting needle 2 enters the stitch X through the hook insertion groove 1411, as shown in FIG. , the stitch X touches the latch 22 closed on the knitting needle 2 . As knitting needle 2 moves upward relative to knitting needle 1 along the needle groove, stitch X opens latch 22, as shown in FIG. Move between the bottom surface. The two knitting needles continue to move together and the stitch X completely enters the hook 22 of the knitting needle 2, as shown in FIG. As shown in FIG. 12, the hook 2 carries the stitch X and is transferred from the spring plate from the lower end of the front side of the protrusion 141, and the stitch X closes the latch 12 on the knitting needle 1 so that the stitch X is completely , and moves completely over the knitting needle 2 as shown in FIG.

Example 2
The structure of the knitting needle of this embodiment is basically the same as that of the above-described Embodiment 1, and you may refer to FIGS. A needle groove guide portion is not provided at the lower end of the hook insertion groove 1411 formed by the inner cavity of the protrusion 141. The only difference is that the slope 14113 sloping to the side is not provided. In order to smoothly insert the knitting needle (for example, the knitting needle 2) correspondingly cooperating, the tip of the hook of the knitting needle of the present embodiment has a gradually widening trapezoid contour surface as shown in FIG. , the narrowest point is smaller than the depth of the groove, and the tip is tapered to facilitate insertion of the hook.

The other structure of the knitting needle 1 of this embodiment and the process of cooperating with the knitting needle 2 during transfer knitting are the same as those of the above-described Embodiment 1, and detailed description thereof will be omitted.

Example 3
The knitting needle 1 of this embodiment, as shown in FIG. 16, has the same hook 11, latch 12 and handle 13 as those of the first embodiment, and similarly, the spring plate 14 is accommodated in the concave groove 133 on one side of the handle. , and the recessed groove 133 spans the corresponding side surfaces of the needle bar 131 and the needle body 132 . The spring plate 14 is provided with a protrusion 141 and a deformation surface 142 located behind the protrusion, and the structure of the deformation surface 142 is the same as that of the first embodiment, that is, it has an outer end portion 1421 and an inclined portion 1422. , see FIG. 3 of Example 1. Similarly, neither the top end surface of the projection 141 nor the most protruding portion (outer end 1421) of the deformation surface 142 protrude from the corresponding outermost side surface of the handle. The front lower end of the protrusion is attached to the groove bottom 1331 of the groove, the inner cavity of the protrusion 141 forms a hook insertion groove, and the depth of the groove is smaller than the thickness of the hook (see FIG. 4). good). However, the lower end of the spring plate 14 is not flat, but protrudes downward to form a latch opening 144 at the front side position corresponding to the second transfer portion, and the latch opening 144 is not lower than the lower end of the handle 13. , is used to open the latch of the knitting needle in the hook insertion groove, and is used to ensure that the latch is opened when the knitting needle to be inserted into the stitch is inserted into the hook insertion groove of the knitting needle having the stitch. It solves the problem of not being able to secure it in the first place, and effectively prevents the occurrence of the "monofilament" problem. At the lower end of the hook inserting groove 1411 formed by the internal cavity of the protrusion 141, a needle groove guide portion consisting of an inclined surface 14113 inclined rearward from the groove bottom surface 1331 is provided, and as shown in FIG. The lower end of the insertion groove 1411 has a bell-mouth shape that facilitates insertion of the hook, and as shown in FIG. The tip also has an arc contour structure, and the other structures of the knitting needle of this embodiment, such as the first transfer portion, the second transfer portion, and the connection form between the spring plate and the handle, are all the same as in the first embodiment. Therefore, they will not be described in detail individually.

The knitting needles of this embodiment perform transfer knitting, and after the knitting needle 2 is inserted into the needle groove guide portion from below the hook insertion groove 1411 of the knitting needle 1, the latch 22 is turned downward as shown in FIG. It is opened by touching the protruding latch opening portion 144 . When the hook of the knitting needle 2 is inserted into the hook insertion groove 1411, the deformation surface of the spring plate on the knitting needle 1 deforms and rotates outward to drive the protrusions to expand outward, and the stitch X is formed. Unfolded, reference may be made to FIG. Next, the knitting needle 1 and the knitting needle 2 move relative to each other based on the set program, and the hook 21 of the knitting needle 2 is placed in the stitch X that is hooked to the first transfer portion and the second transfer portion while the latch 22 is opened. to go into. Next, as shown in FIG. 19, the knitting needle 2 is completely inserted into the stitch X, and then, as shown in FIG. 21, the stitch X is transferred from the spring plate and closes the latch 12 on the knitting needle 1 during the movement of the stitch relative to the needle bar, and as shown in FIG. placed on top of 2.

Example 4
The structure of the knitting needle of this example is basically the same as that of Example 3 above, so please refer to FIGS. .

The spring plate 14 on the knitting needle of this embodiment, as shown in FIG. to form During transfer knitting, the corresponding knitting needle 2 is inserted into the hook insertion groove 1411 of the knitting needle 1 having the stitch X, causing outward rotational deformation on the deformation surface 142 on the knitting needle 1 to drive the protrusion 141 outward. 23, and the stitches X are spread out as shown in FIG. When the knitting needle of the present embodiment performs transfer knitting, the latch opening portion 144 opens the latch, the hook 21 enters the stitch X and is completely inserted into the stitch X, and the knitting needle 2 transfers the stitch X. For the process of fully laying on the knitting needle 2, reference may be made to Figures 17-21.

Example 5
The knitting needle of this embodiment, as shown in FIGS. 24 and 25, has the same hook 11, latch 12 and handle 13 as in Embodiment 1, and similarly, the spring plate 14 is inserted into the concave groove 133 on one side of the handle. The spring plate 14 is provided with a projection 141, a deforming surface 142 located on the rear side of the projection, and a latch opening portion 144 projecting downward at the front side position corresponding to the second transfer portion. The portion 144 is flush with the lower end of the handle 13 and is used to open the latch of the knitting needle in the hook insertion groove. The top surface of the protrusion 141 does not protrude from the corresponding outermost side of the handle, the inner cavity of the protrusion 141 forms a hook insertion groove 1411, and the depth h of the groove is smaller than the thickness of the hook (Fig. 4). At the lower end of the hook insertion groove 1411 is provided a needle groove guide portion consisting of a slope 14113 inclined rearward from the groove bottom surface 1331, and the lower end opening of the hook insertion groove 1411 facilitates the insertion of the hook. make it look like

The differences between the spring plate 14 of this embodiment and the third embodiment are as follows. The deformation surface is not bent and is a flat surface extending rearward from the rear side of the projection, and is attached to the groove bottom surface 1331 of the recessed groove 133. The front side of the deformation surface faces upward along the width direction from the rear side of the projection. , the second transfer portion is positioned at the connection point between the deformation surface and the projection, and the knitting needle 2 inserted inside the projection in this way is positioned between the hook insertion groove and between the deformation surface and the groove bottom surface. exercise in The deformed surface inserts the knitting needle 2 into the hook insertion groove to cause deformation and rotation, and the knitting needle 2 enters between the deformation surface and the groove bottom surface of the recessed groove 133 from the hook insertion groove, thereby increasing the amount of deformation. However, such a structure can be used for knitting requiring a relatively large amount of spread. Other structures of the knitting needle of this embodiment, such as the first transfer portion and the connection type between the spring plate and the handle, are all the same as those of the third embodiment, and therefore will not be described in detail.

The knitting needle of this embodiment performs transfer knitting, and when the knitting needle 2 is inserted into the hook insertion groove 1411 from the needle groove guide portion of the knitting needle 1, the latch 22 touches the latch opening portion 144 protruding downward. It will be opened, see FIG. Further, by inserting the hook 21 of the knitting needle 2 into the hook insertion groove 1411 of the knitting needle 1, the deformed surface of the spring plate on the knitting needle 1 is deformed and rotated outward, driving the protrusion to rotate outward. , and the stitch X is spread. Next, the knitting needle 1 and the knitting needle 2 move relative to each other based on the set program, and the hook of the knitting needle 2 moves from the hook insertion groove to between the deformation surface and the groove bottom surface of the concave groove 133 in a state where the latch is opened. Then, as shown in FIG. 26, it enters the stitch X that is applied to the first transfer portion and the second transfer portion. At the same time, as shown in FIG. 27, the deformed surface is deformed and rotated outward again, the width of the deformed rotation is increased, and the stitch X is widened again. Next, the hook 21 of the knitting needle 2 is completely inserted into the stitch X as shown in FIG. Thereafter, as shown in FIG. 29, the hook 2 is transferred from the spring plate from the lower end of the front side of the protrusion 141 with the stitch X, and the stitch X closes the latch 12 on the knitting needle 1, and the stitch X is shown in FIG. The stitch X is completely transferred from the knitting needle 1 so that the stitch X is held.

Example 6
This embodiment is based on the above-described Embodiment 3, and the depth h of the groove formed between the top end surface 14111 and the bottom end surface (that is, the groove bottom surface 1331) of the hook insertion groove 1411 is the thickness of the hook. The only difference is the structure not smaller than δ, and the other structures are the same as in Example 5. In such a case, when the hook 21 of the knitting needle 2 of Example 5 is inserted into the hook insertion groove 1411, as shown in FIG. However, when the knitting needle 2 moves from the hook insertion groove between the deformation surface and the groove bottom surface, the deformation surface 142 rotates outward due to elastic deformation, driving the projections 141 to spread outward. As a result, as shown in FIG. 32, the stitches X positioned at the first transfer portion and the second transfer portion are widened.

If the bent end of the deformation surface 142 and the upper end surface of the protrusion 141 have a portion exposed from the groove 133, the portion exposed from the groove 133 is restricted by the needle groove 911 (that is, the corresponding groove wall 9111). 34, it is elastically pressed into the recessed groove 133. As shown in FIG. 6, 8, 9, 11, 12 and 13 may be referred to for the transfer knitting process of the knitting needles.
