Assemblable keyboard and assemblable key

An assemblable keyboard, comprising:

• plural assemblable keys, wherein each of the plural assemblable keys comprises:
• a pedestal comprising a frame and a first coupling structure or a second coupling structure, wherein the first coupling structure or the second coupling structure is formed on a lateral wall of the frame;
• a key structure disposed within the frame of the pedestal to generate a key signal, wherein one of the plural assemblable keys with the first coupling structure and an adjacent assemblable key of the plural assemblable keys with the second coupling structure are combined together through engagement between the first coupling structure and the second coupling structure;
• and
• a conductive structure disposed under the key structure and extended to the first coupling structure or the second coupling structure of the frame, wherein when the key structure is depressed, the key signal is generated and the key signal is transmitted to the adjacent assemblable key through the first coupling structure and the second coupling structure;
• and
• a main control key electrically connected with a specified assemblable key of the plural assemblable keys, and comprising a keyboard processor and a transmission interface, wherein the key signal is processed by the keyboard processor, the transmission interface is electrically connected with the keyboard processor, and the key signal is transmitted to a computer host through the transmission interface.
