All bidirectional threaded rods 33 are threadedly connected to threaded blocks 34, and all threaded blocks 34 are connected to the second fork arm body 4; When it is necessary to adjust the distance between the two sets of second fork arm bodies 4, the stepper motor 32 is turned on. With the support of the moving bracket 27, the stepper motor 32 drives the bidirectional threaded rod 33 to rotate. With the threaded connection between the bidirectional threaded rod 33 and the threaded block 34, the bidirectional threaded rod 33 drives the threaded block 34 to move in opposite directions, which in turn drives the second fork arm bodies 4 to move in opposite directions, thereby adjusting the distance between the two sets of second fork arm bodies 4. This enables the electric stacker truck to conveniently adjust the distance between the second fork arms for operation, making it easier to lift rack pallets of different sizes and improving the convenience of the electric stacker truck in inserting and lifting rack pallets.

[0026] Work steps A dual-axis motor 21 drives a rotating shaft 22 to rotate, which in turn drives a sprocket 24 to rotate. The sprocket 24 then drives a chain 25 to rotate, which in turn drives the support block 26, the movable bracket 27, and the second fork arm body 4 to move upwards. Simultaneously, the chain 25 drives a counterweight block 31 to move downwards, thus quickly lifting the goods to the desired height. When it is necessary to lift the next set of goods, an electric push rod 14 drives a fourth shaft 15 to move. The fourth shaft 15 drives an H-shaped support frame 9 to rotate around a fifth shaft 16. The H-shaped support frame 9, via a sixth shaft 18, drives a second sliding block 19 to move, causing the second sliding block 19 to slide inside a second slide groove 17, allowing the second slide groove 17 and the first fork arm 3 to slide together. When the first fork arm 3 moves upward, it drives the two sets of seventh shafts 20 to move upward. The seventh shafts 20 drive the U-shaped support frame 8 to rotate. The U-shaped support frame 8 drives the first sliding block 11 to move through the first shaft 10, so that the first sliding block 11 slides inside the first slide groove 7, thereby lifting the goods. When it is necessary to adjust the distance between the two sets of second fork arm bodies 4, the stepper motor 32 drives the bidirectional threaded rod 33 to rotate, so that the bidirectional threaded rod 33 drives the threaded block 34 to move in opposite directions, so that the threaded block 34 drives the second fork arm bodies 4 to move in opposite directions, thereby adjusting the distance between the two sets of second fork arm bodies 4 to complete the operation of the electric stacker truck.
