[0032] The design of the positioning pillar 5 is convenient for supporting and fixing the rotating shaft insert with the rotating slot 6. A through slot 8 is provided at the center of one side of the inner wall of the two rotating slots 6 and at the center of one side of the two positioning pillars 5. The design of the through slot 8 is convenient for clamping the locking block 7. The two through slots 8 located in the same positioning pillar 5 among the four through slots 8 are movably clamped with the locking block 7. The locking block 7 can close the rotating slot 6, which has the effect of limiting the position of the rotating shaft insert.

[0033] A slide groove 9 is provided at the center of one side of the two positioning pillars 5, and a slider 10 is clamped in the two slide grooves 9. An L-shaped top block 12 is fixedly provided at the center of one side of the two sliders 10. The L-shaped top block 12 can push the locking block 7 to move by moving up and down. A wedge block 13 is fixedly provided at the lower end of the center of one side of the two L-shaped top blocks 12. A cavity 16 is provided on the lower end surface of the inner wall of two through grooves 8 on the same side of the two positioning pillars 5 among the four through grooves 8. An embedding groove 11 is provided at the center of one side of the two cavities 16. The design of the wedge block 13 is convenient for embedding into the embedding groove 11 to clamp and fix the position of the L-shaped top block 12.

[0034] When in use, first insert the rotating shaft into the rotating card slot 6, push the locking block 7 to the appropriate position along the through slot 8, and then push the slider 10 upward along the slide slot 9, and drive the L-shaped top block 12 to move upward through the slider 10, and use the arc surface of the upper end surface of the L-shaped top block 12 and the side of the locking block 7 to reduce the resistance of mutual contact, forcing the locking block 7 to move to one side and insert into the rebound groove 15, and then press the slider 10 to one side so that the wedge block 13 is embedded in the embedding groove 11, and the vertical position of the L-shaped top block 12 is fixed, and then the sliding block 17 is moved along the sliding slot 4 to adjust the distance between the two positioning pillars 5, so that the two positioning pillars 5 squeeze and clamp the rotating shaft insert to prevent The shaft insert shakes back and forth during use, affecting the injection molding effect.
