The fixing plate 5 has several mounting holes 8 and auxiliary mounting holes 9. The long strip housing 1 is placed at the marked position on the mounting surface. External mounting screws, using a tool, are screwed into the mounting surface through the mounting holes 8 and auxiliary mounting holes 9. A U-shaped protrusion 6 is fixedly connected to the inner wall of the long strip housing 1 near the positioning slider 3. Both the fixing plate 5 and the U-shaped protrusion 6 are integrally cast with the long strip housing 1. The U-shaped protrusion 6 has an adjustment function. The upper end of the vertical section sidewall at the center of the bolt 7 and the U-shaped protrusion 6 is provided with an arc-shaped limiting hole 10. The adjusting bolt 7 is set through the two arc-shaped limiting holes 10. The arc-shaped limiting holes 10 are used to limit the adjustment bolt 7 and facilitate the rotation of the adjusting bolt 7. The positioning slider 3 is provided with a first threaded hole 11 at the lower end of the adjusting bolt 7. The adjusting bolt 7 is threadedly connected to the first threaded hole 11. When it is necessary to adjust the position of the positioning hole 4 on the positioning slider 3, simply use a tool to turn the adjusting bolt 7, so that the adjusting bolt 7, in conjunction with the first threaded hole 11, drives the positioning slider 3 to move smoothly under the limiting action of the concave section 2.
