In the slide grooves 12 on both sides, first sliders 13 and second sliders 14 arranged vertically corresponding to each other are slidably connected. Support legs arranged correspondingly on both sides are rotatably connected to the first sliders 13. On one side of each of the support legs on both sides, an adjusting rod 17 is hinged. The other ends of the adjusting rods 17 on both sides are hinged to one side of the second slider 14. Fixing mechanisms cooperating with the main fence 1 are provided on both the first slider 13 and the second slider 14. The fixing mechanisms include limiting slide bars located on both sides of the first slider 13 and the second slider 14. Limiting grooves cooperating with the limiting slide bars are provided on both sides in the slide groove 12. Threaded holes penetrating through are provided on both the first slider 13 and the second slider 14. A first fixing bolt 18 is threadedly connected in the threaded hole. The support leg includes a telescopic sleeve 15 rotatably connected to one side of the first slider 13. A movable rod 16 is slidably inserted into the lower end of the telescopic sleeve 15. A second fixing bolt 21 cooperating with the movable rod 16 is threadedly connected to the telescopic sleeve 15.

[0023] The upper end of the main fence 1 is fixedly connected with an adjustment vertical plate 3 arranged correspondingly on both sides, and the adjustment vertical plates 3 on both sides are provided with a strip-shaped horizontal hole 4, and the strip-shaped horizontal holes 4 on both sides are rotatably connected with a rotating shaft 5, and a secondary fence 2 is fixedly connected between the rotating shafts 5 on both sides. The upper end of the main fence 1 is provided with a movable slot 6, and a fixed plug plate 7 is slidably inserted in the movable slot 6, and a fixing spring 8 matched with the fixed plug plate 7 is fixedly connected to the bottom surface of the movable slot 6. The secondary fence 2 is provided with a fixed slot 9 matched with the fixed plug plate 7 at one end close to the main fence 1, and a shift block 10 is provided on one side of the fixed plug plate 7.
