[0039] Working principle: When relevant personnel need to perform laser additive manufacturing on the copper sleeve, first place the copper sleeve on top of the fixed column 2, and then rotate the bolt 11 to release the contact limit between the bolt 11 and the fixed column 2, and then the turntable 6 can be rotated. When the turntable 6 rotates, it will drive the connecting plate 9 and its limit block 8 to move, and the limit block 8 will move along the arc groove of the fixed column 2. At this time, the volute spring 13 will be stretched. Since the plug-in column 14 is plugged and fixed with the movable plate 12, the movable plate 12 and the brush roller 10 will move upward, and then the impurities and oil stains on the inner wall of the copper sleeve will be cleaned. The operation is simple and convenient. At the same time, when the turntable 6 rotates, it will drive the three sets of guide blocks 5 and their extrusion rods 4 to move, so as to clamp and fix the copper sleeve.

[0040] When the copper sleeve is clamped and fixed, the bolt 11 is rotated to limit the turntable 6, and then the plug-in column 14 is moved outward, so as to release the plug-in fixation of the plug-in column 14 and the movable plate 12, and then the movable plate 12 is reset due to the elasticity of the spiral spring 13, and the brush roller 10 is also reset at the same time, so the brush roller 10 will not affect the nozzle 18 to process the copper sleeve. When laser additive work is not needed, the limit of the turntable 6 by the bolt 11 is released, and then the turntable 6 is rotated in the opposite direction. At this time, the turntable 6 moves downward, and then the limit block 8 and the plug-in column 14 move downward. When the inclined surface of the plug-in column 14 contacts the movable plate 12, the plug-in column 14 moves. When the two are not in contact, the plug-in column 14 is reset due to the elasticity of the connecting spring 15, and then the plug-in column 14 is plugged with the movable plate 12, which is convenient for subsequent operations.

[0041] When the nozzle 18 needs to be replaced, the plug-in plate 22 is moved so that the plug-in plate 22 is not plugged into the fixing block 19, and then the nozzle 18 can be moved downward to replace the new nozzle 18. The operation is simple and convenient, and the use of screws for installation is avoided, thereby achieving the purpose of more convenient disassembly and installation.
