[0027] In use, place one end of the water-cooled wall tube to be welded inside the left V-groove 3, and move the right end of the water-cooled wall tube into the welding groove 2. Then, turn the left handwheel 103 to rotate the left worm gear 102, which in turn rotates the left first threaded rod 7 through the left worm wheel 101. During the rotation of the left first threaded rod 7, the left moving block 9 and the left clamping block 15 move downward through the left threaded sleeve 8, thereby clamping and fixing the water-cooled wall tube. Then, place the bent tube to be welded inside the right V-groove 3, and make sure the left end of the bent tube is tightly fitted with the right end of the water-cooled wall tube. Similarly, turn the right handwheel 103 to move the right moving block 9 and the right clamping block 15 downward, thereby clamping and fixing the bent tube. At this point, the connection between the water-cooled wall tube and the bent tube can be welded. When performing welding operations, if it is necessary to clamp and fix pipes of different diameters, the two knobs 255 can be turned to rotate the two second threaded rods 254, thereby moving the two sliders 252 and the two fixing blocks 253 upward, so that the two fixing blocks 253 can be moved out of the two fixing grooves 24 respectively, thus releasing the position restriction of the two positioning blocks 20. Then, the two pull rings 23 can be pulled to move the two pull rods 21 and the two positioning blocks 20 in opposite directions, so that the two positioning blocks 20 can be moved out of the two positioning grooves 19 respectively, thus releasing the fixation of the two connecting blocks 14. At this time, the two clamping blocks 15 can be pulled downward to remove them, which facilitates the replacement of clamping blocks of different sizes, and enables clamping and fixing operations on pipes of different diameters, greatly improving the applicability of the tool.

[0028] In summary, this water-cooled wall pipe bend fitting tool rotates two second threaded rods 254 by turning two knobs 255, which in turn moves two sliders 252 and two fixing blocks 253 upwards. This causes the two fixing blocks 253 to move out of the two fixing slots 24, thus releasing the positional restriction on the two positioning blocks 20. Then, pulling two pull rings 23 moves two pull rods 21 and two positioning blocks 20 in opposite directions, causing the two positioning blocks 20 to move out of the two positioning slots 19, thus releasing the fixation on the two connecting blocks 14. At this point, pulling down the two clamping blocks 15 allows for easy disassembly of the clamping blocks 15, facilitating the replacement of clamping blocks of different sizes and enabling clamping and fixing of pipes of different diameters. This greatly improves the tool's applicability and solves the problem that existing fitting tools often have fixed clamping blocks that are difficult to disassemble and replace, making it inconvenient to clamp and fix pipes of different diameters, thus hindering their use.
