1. A negative pressure suction-based fixing device, comprising
a housing having an accommodating cavity thereinside;
a suction and holding member having an abutting and holding surface that is recessed to form a suction cavity in communication with the accommodating cavity and is provided with a mounting structure;
a sealing member that is connected to the mounting structure to be arranged on the abutting and holding surface, wherein the sealing member is configured to be abutted and held on a suction surface, and is capable of being elastically deformed to fit with the suction surface so as to form an enclosed space cooperatively with the suction cavity and the suction surface, wherein the sealing member is a colloid; and
a negative pressure creating assembly configured to generate negative pressure in the accommodating cavity so as to create negative pressure in the enclosed space.
