In this embodiment, the number of limiting grooves 111 is four. In other embodiments, the number of limiting slots 111 can also be other integers. The limiting groove 111 includes a first groove cavity 1111 and a second groove cavity 1112 whose extension directions are perpendicular to each other. Both the first groove cavity 1111 and the second groove cavity 1112 are rectangular parallelepiped.
