[0027] As a further implementation of the present invention, a connecting screw 5 is spirally connected to the inner side of the threaded hole 36, the top of the connecting screw 5 is arc-shaped, and the top of the connecting screw 5 is installed on the inner side of the annular groove 25. The connecting screw 5 can be used to position the handle 31 and the fixing column 22, further improving the stability of the connection between the handle 31 and the fixing column 22.

[0028] As a further implementation of the present invention, the limiting mechanism 4 includes a movable baffle 41, the middle of the movable baffle 41 is fixedly connected to the movable rod 42, the movable rod 42 is T-shaped, and the middle convex position of the movable rod 42 is slidably connected to the handle 31 through the second limiting groove 34. Through the above arrangement, the movable rod 42 can be stably limited, further improving the stability of the movable rod 42 during movement;

[0029] As a further implementation of the present invention, the fixing column 22 is installed inside the third limiting groove 35. The vertical section of the third limiting groove 35 is circular. The fixing column 22 is rotatably connected to the handle 31 through the spring 26 and the third limiting groove 35. The fixing column 22 and the spring 26 can be stably stored through the third limiting groove 35.

[0030] As a further implementation of this solution, the center points of the limiting transverse groove 23, the limiting mechanism 4 and the second magnetic block 33 are arranged on the same horizontal plane, and the edge of the limiting transverse groove 23 is arc-shaped.

The handle 31 rotates relatively with the connecting control column 21 and the fixed column 22 through the spring spring 26. At this time, the control column inside the door lock cannot be controlled to rotate through the fixed column 22, and the door lock cannot be opened. In this way, in actual application, it can prevent the problem of children or pets turning the handle 31 to open the door lock;

[0034] At the same time, the user can move the moving rod 42 through the moving baffle 41 to a position in contact with the first magnetic block 24. At this time, the moving rod 42 is inserted into the limiting horizontal groove 23. During the process of rotating the handle 31, the handle 31 can be controlled by the moving rod 42 to rotate the connecting control column 21, and then the door lock can be opened normally when the handle 31 is rotated.
