[Action]

 When the upper portion of the base body 2 is pulled toward the front from the state where the base body 2 is housed in the box body 10, the hooking protrusion 7 on the upper end of the sleeve 1 is formed in the box upper part of the inside of the box body 10 in the shape of a barb 1 1, the base 2 is inclined at a constant angle and stops when the gap 6 comes out of the box 10 together with the upper part of the base 2. At that time, the tip of the thread insertion rod 13 comes out from the circular arc square hole 5 in front of the gap 6, and remains in the circular arc square hole 5 rearward of the gap 6. After that, when the base body 2 is lightly pushed back into the box body 10 and further pushed to the back, the tip of the thread insertion rod 13 projects from one end before the arcuate square hole 5. Therefore, when the upper portion of the base 2 is pulled a little toward you, the positioning protrusion 8 formed in the inner upper part of the box 10 is fitted into the positioning recess 8 formed in the upper part of the sleeve 1, so that the base 2 is stabilized. It stands upright and fits inside the box 10.

Therefore, in use, when the gap A is placed outside the box body 10 together with the upper portion of the base body 2, the thread A is placed in the gap 6 and the needle B is inserted into the round vertical hole 3 from the head. Since the head fits into the square lateral hole 4 and the needle hole faces the direction of the circular arc square hole 5, the base body 2 is lightly pushed back into the box body 10, and when pushed further to the back, the thread insertion rod 13 pushes the thread A. The tip of the circular arc hole 5 is projected. After that, when the needle B is pulled out from the round vertical hole 3 again after the gap between the upper portion of the base 2 and the gap 6 is exposed from the box 10, the thread A passes through the needle B.
