A heat exchanger fin body 327 is arranged between the clamping plates 326, and the heat exchanger fin body 327 is located on the top of the L-shaped placement plate 3112.

[0049] By providing the clamping plates 326 , two groups of clamping plates 326 are connected to the square slider 322 via the connecting plate 325 for clamping the fins.

After the clamping mechanism stably clamps the fin, subsequent processing operations can be carried out. After the processing is completed, the hydraulic cylinder 329 retracts and the L-shaped limit plate 3210 returns, releasing the initial limit on the fin. At the same time, the elastic force of the spring 324 causes the square slider 322 and the clamping plate 326 to move in opposite directions, releasing the clamping force on the fin. At this time, the processed fin can be easily removed for the next round of operation.
