A symmetrically arranged limit plate 1 9 and a limit plate 2 10 are provided in the limit hole 8, and the limit plate 1 9 and the limit plate 2 10 are connected to the limit block 7 through a limit assembly. Example

[0023] like Figure 1-3 As shown, the limiting assembly includes a cavity located in the limiting block 7 and above the limiting hole 8, and a movable part 1 20 and a movable part 2 21 extending into the limiting hole 8 are respectively provided in the cavity, and a U-shaped frame 11 is provided at the bottom end of the movable part 1 20 and the movable part 2 21, and the two groups of U-shaped frames 11 are respectively provided with connecting blocks 12 connected to the limiting plate 1 9 and the limiting plate 2 10, and the connecting blocks 12 are connected to the U-shaped frames 11 through a movable shaft 13, and the movable part 1 20 and the movable part 2 21 are provided with a rotating shaft 14 connected to the limiting block 7, and a movable block 15 is provided in the cavity that transversely penetrates the movable part 1 20 and the movable part 2 21, and a through hole 16 is provided at the top of the movable part 1 20 and the movable part 2 21 for the movable block 15 to penetrate.
