In the case where the locking hooks belonging to the locking knife are provided with two main hooks, the knives 2 and 3 are placed parallel to the main needle 5 and individually on both left and right sides of the vertical needle 1. The knives are arranged on the same plane at positions where they do not interfere with each other and are spaced apart so that the needles 1 can pass through, and the heads of the needles 1 extend continuously to both the left and right sides. The main hooks 4, 4' are formed by protruding the left and right ends in a downward diagonal direction, and the knives 2, 3 are formed into a T-shape.
are provided with edges 11, 12 for engaging the hooks 4, 4', and have protrusions 13, 14 formed at their outer ends parallel to the knife, and the needle is arranged parallel to the main needle 5. A locking hook 9 that engages with a locking knife 8 is disposed protrudingly, and the vertical needle 1 can be adjusted and moved along the knives 2 and 3 in the pushing direction (arrow) of the main needle.

図中６，７はナイフ支持材。In the figure, 6 and 7 are knife supports.

錠止ナイフ８は固定板１０が押抜かれ折曲げられて舌状
体状に形成されている。The locking knife 8 is formed into a tongue-like shape by punching out and bending a fixing plate 10.

１３，１４はエツジ１１．１２の外側端に突設した突起

うにしたものである。Numerals 13 and 14 are protrusions protruding from the outer ends of the edges 11 and 12 to prevent the hooks 4 and 4 from coming off when engaged with the edges.

ナイフ２，３は上部反転位置及下部反転位置に位置する
ときは、各同一平面に位置し、 互に列内移動して通過しあうときは互に外側に回避して
衝突せしめないよう構成する（第４図）。When the knives 2 and 3 are located at the upper inverted position and the lower inverted position, they are positioned on the same plane, and when they move within the row and pass each other, they avoid each other to the outside so that they do not collide. (Figure 4).

持ち上げられない。In addition, the knife 3 has a space on the right side of the protrusion 14 formed to protrude upward, and the knife 2 has a flat plate surface 15, and when the hook 4 is located opposite to this surface, the needle 1 is lifted by the knife 2. Also, if the hook 4' is located opposite the protrusion 14 or the right side thereof, the needle 1 will not be lifted by the knife 3.

高速運動にもよく適合せしめえた効果がある。Since the present invention has the above-mentioned structure, the knives 2.3 are arranged parallel to the main needle 5 and separately on the left and right sides of the vertical needle, and the knives are on the same center line in the upper and lower inverted positions. Therefore, when they move in opposite directions, they avoid each other to the outside and do not collide, and the edge portions 11 and 12 protrude in the upper and lower portions, and the hook portions 4 and 4' protrude in each direction, and a protrusion is formed at the outer end. This allows the hook part to slide deeply into the edge part, thereby eliminating the risk of the vibration of the needle making the engagement movement more reliable, and allowing for high-speed movement. It also has the effect of being well adapted.
