The invention discloses an easily detachable type all-steel network movable floor. The easily detachable type all-steel network movable floor comprises a single floor body and a connection piece; extending bodies are arranged on the circumferential side of the single floor body, a plurality of plug-in holes are formed in the extending bodies, and a plurality of grooves are distributed in the circumferential side of the inner walls of the plug-in holes along the circumference; and the connection piece comprises two plug-in columns, two moving mechanisms, two power mechanisms and an adjusting device. The acting force received by the adjusting device is transmitted to the moving mechanisms through the power mechanisms, and the moving mechanisms move to adjust the radius sizes of the plug-in columns. The plug-in columns, the moving mechanisms and the power mechanisms on the connection piece cooperate with the adjusting device, the adjusting device acts to drive the power mechanisms, thereof driving the moving mechanisms to move, so that the radius of the plug-in columns decreases under the effect of the moving mechanisms, thus the connection piece can be conveniently dismounted and mounted, two adjacent single floor bodies can be connected through the connection piece, the stability of connection of the floor is improved greatly, and the easily detachable type all-steel network movable floor has the characteristics of being easy to mount and dismount and stable and reliable in connection.
