The first slide groove 101 and the second slide groove 201 are rectangular strip holes, which are respectively located in the middle of the first positioning plate 1 and the second positioning plate 2. The first slider 5 and the second slider 6 are provided with rectangular openings, and the openings are respectively adapted to the first positioning plate 1 and the second positioning plate 2, so that the first positioning plate 1 and the first slider 5 are staggeredly connected to each other, and the second positioning plate 2 and the second slider 6 are staggeredly connected to each other, so that the first slider 5 and the second slider 6 are always perpendicular to the first positioning plate 1 or the second positioning plate 2 during the sliding process, thereby making the adjustment position of the first slider 5 and the second slider 6 more accurate.

[0036] Specifically, the first adjustment rod 501 and the second adjustment rod 601 are both screw rods, the second locking structure and the fourth locking structure are nuts 4, a first threaded hole for the first screw rod to pass through is provided on the first slider 5, and a second threaded hole for the second screw rod to pass through is provided on the second slider 6.
