The movable plates 22 are arc-shaped and symmetrically arranged, and a movable plug plate 221 is arranged between the movable plates 22. The movable plug plate 221 is arranged inside the movable plate 22. The movable plates 22 can adjust the spacing according to actual conditions to play a positioning role and avoid the tilting of the latch rod during the installation process.

[0024] The movable plate 22 is fixedly connected with a limiting ball, and a fixed shaft is clamped on the limiting ball. A plurality of positioning shafts 23 are arranged on one side of the movable plate 22. The positioning shafts 23 are inclined. A fixing ring 24 is fixedly connected between the positioning shafts 23.
