In some examples, the grip handle 15 may be disposed on the top of the can body 1, or may be disposed on the sidewall of the can body 1. Therefore, the grabbing handle can be arranged at different positions according to the requirements of actual conditions, so that the refrigerant tank can be conveniently lifted to move.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalents, improvements and the like made by those skilled in the art within the spirit and principle of the present invention should be included in the protection scope of the present invention.
