[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] A padlock device for an electric earthing switch with a limit function comprises a fixed plate 1, a baffle 2, a pin 3, and a handle 4. The fixed plate 1 is connected to the baffle 2 by the pin 3. An operating hole 11 is provided on the fixed plate 1. The operating hole 11 is square. The handle 4 comprises a gripping portion 41, a connecting portion 42, and an operating portion 43. The gripping portion 41, the connecting portion 42, and the operating portion 43 are connected in sequence. The operating portion 43 is also square in shape and matches the operating hole 11. The fixed plate 1 is hinged to the baffle 2 by the pin 3.

[0026] The fixing plate 1 is bent at a right angle, the baffle 2 is bent in a step shape, and the space between the baffle 2 and the fixing plate 1 is increased by bending, thereby ensuring that when the grounding switch is electrically operated, the locking plate will not be blocked by the baffle 2. The gripping portion 41 may be spherical, and the connecting portion 42 is bent, and the bending angle of the connecting portion 42 is 90°.

[0027] The operating hole 11 on the fixed plate 1 is square, and the operating portion 43 of the corresponding handle 4 is also square. When the handle 4 is rotated, the handle 4 can be pulled out only at 90° and 180°. When it is not in this position, the operating hole 11 of the fixed plate 1 blocks the operating portion 43, and the handle 4 cannot be pulled out, thereby reducing the possibility of misoperation of the grounding switch and ensuring that the handle 4 of the grounding switch can only be pulled out when the grounding switch is in the open position or the closed position.
