[0025] This utility model discloses a novel transformer pin bending device. During operation, a suitable first and second placement plate are selected. The first placement plate drives two sets of first locking blocks to engage with the rear end slots of the first mounting block. Then, the second locking block at the rear end of the second placement plate and the front end slot of the second mounting block are engaged. The two sets of first and second screws are rotated to rotate with their corresponding first locking blocks, thus completing the fixing. The operator then rotates the third screw using the second handle, causing the first slider to slide along the second mounting block, bringing the front end of the second placement plate into close contact with the rear end of the first placement plate via a positioning block. The operator then inserts the transformer pin into the arc-shaped hole in the placement plate. The control module is then activated, sending a command to the telescopic cylinder. The output end of the telescopic cylinder pushes the pressure plate, which, guided by the guide block, moves smoothly along the inner side of the annular plate, bending the pin. Before completing the above actions, the device is first moved to the desired position by the user.
