[0003] Since the length-diameter ratio of the discharge tube is very large, a centripetal conical protrusion, called a spike (referred to as a cavity wall support body in the present application), is needed to be fired on the water cooling tube when firing the tube shell; generally, three spikes are formed and evenly distributed on the same circumference; according to the length of the laser tube, more than one set of spikes can be fired. However, the spikes are manually fired and directly fired on the inner wall of the water cooling tube, the firing process is difficult, and the depth of the fired spikes is difficult to control; if the depth is too shallow, the spikes cannot support the discharge tube; if the depth of the fired spikes is too deep, the discharge tube can be deformed by being squeezed; more seriously, the water cooling tube can be broken, causing the tube shell to be scrapped; the consistency of the spikes cannot be guaranteed, and the straightness of the discharge tube cannot be guaranteed.
