A laser tube with a water passing structure, comprising a laser lens and a glass tube. The glass tube comprises an air return tube (3), a middle water nozzle (4), a connection fixing column (5), a water passing tube (6), a tail water nozzle (9), a water sleeve (10), a discharge tube (11) and an air storage tube (14). When the glass tube is fired, the middle water nozzle (4) is located at a position, close to a middle, of the water sleeve (10), thereby reducing dropping and bending of the water sleeve caused by an over-long supporting distance of the water sleeve. The middle water nozzle (4) is connected to a front end of the water sleeve (10) via the water passing tube (6). A connecting part of the middle water nozzle (4) and the water passing tube (6) is fixed to the water sleeve (10) via the connection fixing column (5). By means of the laser tube, the middle water nozzle is connected to the position, close to the middle, of the water sleeve via the connection fixing column, thereby effectively shortening the supporting distance of the water sleeve and reducing dropping and bending of the water sleeve caused by the over-long supporting distance of the water sleeve. |
