Example two
Compared with the first embodiment, the present embodiment differs only in that: the adjusting groove is a through groove 22 penetrating through the positioning plate 2, and the limiting column 3 is inserted into the through groove 22 in a relatively movable manner. When the locating plate 2 moves and adjusts relative to the mounting groove 11, the limiting column 3 can adaptively move in the through groove 22, and the through groove 22 and the limiting column 3 can be matched to limit the locating plate 2, so that the locating plate 2 is prevented from being separated from the mounting groove 11, and at the moment, the locating plate 2 is adjusted to move up and down and left and right along the opening area of the through groove 22. In this embodiment, the through groove 22 is a bar-shaped through hole formed along the height direction of the positioning plate 2, and when the positioning plate 2 moves along the height direction of the mounting groove 11, the limiting post 3 can relatively move in the bar-shaped through hole, so as to realize the height adjustment of the positioning plate 2.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being apparent from variations or modifications that may be made by those skilled in the art are within the scope of the invention.
