[0033] Using a printing plate cylinder structure according to this embodiment, by providing two sets of the connection components, when it is necessary to weld two of the plugs 102 to both ends of the tube body 101, first press two of the limit plates 107. At this time, the limit plates 107 drive the telescopic members and the springs 106 to contract, such that the limit plates 107 move towards the connection plates 104. After that, place the limit plates 107 on the fixed rings 103. Then, push the plugs 102. The plugs 102 drive the connection plates 104 to move. The connection plates 104 slide on the fixed rings 103, thereby driving the limit plates 107 to move. After the limit plates 107 move to the designated positions, at this time, the springs 106 reset and extend. The springs 106 drive the limit plates 107 to move.
