Interactive action.

However, the perforation 4' is formed by machining, and therefore, it is easy to cause the wall thickness of the two side walls 41', 42' of the vertical section 2' at the perforation 4' to be uneven, resulting in the upper needle Knot 100' being actuated. It is unstable and yawed; in addition, if the wall thickness is to be uniform, the non-performing rate of production is high, which in turn causes an increase in cost.

In addition, since the vertical section 2' is a single-piece structure, and one end located at the perforation 4' is intended to be integrated, if the knitting needle 200' malfunctions, it means that the knitting needle 200' may not move or stay with When the moving direction of the upper groceries 100' is reversed, the one end of the vertical section 2' having the boring hole 4' is easy to directly hook the hook portion 210' of the knitting needle 200' to cause the upper crocheting needle 100' and the knitting needle 200' Damage and damage.

Furthermore, since the upper crochet 100' is monolithic, its overall thickness is fixed, so that the horizontal section 1' is mounted in the needle slot 310' of the dial 300' because of the width dimension of the needle slot 310'. There will be errors, which will easily lead to the situation that the horizontal section 1' is too tight or too loose when it is installed in the needle groove 310'. Therefore, it is very difficult for the assembly personnel to assemble, and if it is the upper socks needle 100' When the needle slot 310' is actuated, it is also easy to generate friction due to too tight, and the service life becomes shorter, and It is easy to heat up and affect the operation of the machine.

Therefore, when the knitting needle is malfunctioning, the first bending end 13 and the second bending end can be made by the presence of the knitting needle 200' and the elasticity of the first bending end 13 and the second bending end 23 itself. Folding end 23 pushes outward and avoids The damage-free knitting needle and the upper take-up needle structure 100 itself reduce the cost of maintenance and heavy work.

In addition, since the upper crochet structure 100 of the present invention is a two-piece structure, not only can be separately formed by punching, but also the connection of the first joint portion and the second joint portion and the first buffer portion and the second portion are used. The limit connection of the buffer part makes it easy to manufacture and easy to disassemble.

Moreover, compared with the conventional pick-up needle 100' is a single-piece structure, the slight difference in the size of the needle groove 310' (as shown in FIG. 3) in the dial 300' caused by the production error is easy to cause When the upper groceries 100' are installed in different needle slots 310', the situation is too tight or too loose, and there is no buffer space, thereby affecting the actuation thereof; and the two pieces used in the sock needle structure 100 are used in the present creation. The elastic body (ie, the elastic piece 3) disposed between the bodies, the recessed depth d1 of the recessed hole 15 is smaller than the recessed depth d2 of the chute 14, and the degrees of freedom of the second section 12 and the fourth section 22 are defined in the radial direction thereof. The distance between the second segment 12 and the fourth segment 22 can be elastically adjusted to form a buffer, thereby being adapted to the needle groove 210 caused by the production error in the dial 200 (as shown in FIG. 10). Figure 10 shows the slight difference in size.

The above description of the embodiments is intended to be illustrative of the present invention and is not intended to limit the present invention, so any change in the value or substitution of equivalent elements should still fall within the scope of the present invention.
