[0002] Brazing furnace is a kind of equipment used for metal brazing and bright heat treatment. Brazing furnace is used in steel industry, metallurgical industry, etc. It is mainly used for filter refrigeration accessories in the automotive industry, aerospace industry, and can also be used for brazing and bright heat treatment of refrigerators, air conditioners, electronics, microwave magnetron industries and other stainless steel, carbon steel, brass, copper parts. Brazing bracket is a tool or equipment used to assist and support the brazing process. It is usually used to hold and position the workpieces to be welded (usually metals or electronic components) to ensure that they remain stable and in the correct position during the welding process. The main function of the brazing bracket is to simplify the welding operation, improve the accuracy and quality of welding, and reduce the labor intensity of the operator and possible welding defects.

[0003] After searching, the existing Chinese patent announcement number is: CN219852529U, which provides a brazing bracket for a brazing furnace. This patent adjusts the position of the connecting rod, uses the knob to unscrew the fixed screw, adjusts several connecting rods to the appropriate position, and then rotates the knob in the opposite direction until the screw is tightly against the main moving rod, thereby fixing the main moving block and achieving the initial fixation of the structure. After that, the workpiece is placed on the support rod. Since the cross-section of the support rod is circular, the support rod partially protrudes from the limit rod, so the workpiece contacts the top of the support rod, and the contact area is small, which will not affect the subsequent brazing operation; at the same time, the auxiliary moving rod at the bottom of the connecting rod and the auxiliary moving block of the fixed limit rod will move with the movement of the main moving block, and a through hole is provided in the middle of the auxiliary moving block to facilitate moving back and forth on the auxiliary moving rod, thereby further enhancing the stability of the bottom of the connecting rod.

[0004] Although the above patent can enhance the stability of the workpiece during welding, the above brazing bracket for the brazing furnace still has the following problems: the bracket cannot be automatically cleaned to ensure the cleanliness before and after welding; and irregular workpieces cannot be fixed.
