[0002] With the rapid development of integrated circuit packaging technology and the substantial improvement of operating performance, multimedia computers have become popular among consumers, which has accelerated the popularization of computers and related peripheral products. However, with the improvement of integrated circuit operating performance, the number of package pins of various components has also increased significantly, making the layout of related circuit boards more sophisticated and complex, and making it more difficult to repair and replace components on circuit boards.

[0003] In the related art, an adjustable tin furnace nozzle structure is disclosed, which is installed above the tin bath and guides the liquid tin to generate a tin wave at the nozzle for soldering operations; the tin furnace nozzle includes: a nozzle groove, which is used to pump the molten tin out of the nozzle to form a tin wave after the liquid tin in the tin bath enters the nozzle groove; a plurality of grooves, which are respectively located on the inner side of the nozzle groove; and a tin blocking sheet, which is used to be installed at the inner groove of the nozzle groove; by installing the tin blocking sheet at different grooves on the inner side of the nozzle groove, the nozzle groove opening can be divided and combined into nozzles of different shapes and sizes, thereby controlling the shape of the tin wave generated by the tin furnace nozzle and facilitating the replacement of circuit board components of different types and sizes.

[0004] However, the above structure still has some shortcomings. When adjusting the tin furnace nozzle, the size of the nozzle can only be adjusted according to the position of the groove opened on the nozzle. However, this method cannot perform stepless adjustment according to the size of the circuit board.

[0005] Therefore, it is necessary to provide a new adjustable tin furnace nozzle structure to solve the above technical problems. Utility Model Content
