This is the prior art, and the specific principle will not be described in detail.

[0025] In this embodiment, the limiting feeding mechanism 8 includes a folding limit strip 81 and a horizontal limit strip 82 fixed above the placement plate 4.

[0032] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0033] During operation, the pressing plate 83 is pushed backward to neatly arrange the transformers 10 to be tested inside the folding limit strip 81, and then the pressing plate 83 is released.
