Under the condition that the cup cover 1 is not installed correctly, the first locking piece 2 locks the sliding piece 3 and cannot move leftwards, so that the cup assembly 5 is jacked up by the second locking piece 4 when being installed on the main machine 8 and cannot be installed normally.

When the cup cover 1 is correctly screwed into the cup body 6, at the moment, the cup cover 1 pushes the first trigger piece 7 to move towards the right, the first trigger piece 7 pushes the first locking piece 2 to move upwards, so that the sliding piece 3 is unlocked and can move leftwards, and when the cup assembly 5 is installed into the host computer 8, the sliding piece 3 moves leftwards and is inserted into a locking hole of the cup cover 1, so that the cup cover 1 cannot be opened in the working process.

When the work is completed, the cup assembly 5 is removed from the main body 8, and at this time, the second locking member 4 is reset to the right by the force of the third spring 9.

After the cup cover 1 is taken down, the first trigger 7 moves leftwards under the action of the force of the fourth spring 10 to reset, so that the first locking part 2 moves downwards under the action of the force of the first spring 11 to reset, the sliding part 3 is locked, and the sliding part 3 cannot move leftwards.

The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the protection scope of the present invention is defined by the claims. Various modifications and equivalents of the invention can be made by those skilled in the art within the spirit and scope of the invention, and such modifications and equivalents should also be considered as falling within the scope of the invention.
