[0016] 1. This type of farm handcart with adjustable wheel track features an adjustment frame, a sliding groove, a sliding plate, a connecting rod, a turntable, and forward and reverse threads. When wheel track adjustment is needed, the turntable is rotated, causing the connecting rod to rotate. The rotation of the connecting rod then drives the sliding plates on the forward and reverse threads to move horizontally towards each other along the sliding groove, thereby adjusting the distance between adjacent wheels. This design allows the wheel track distance of the handcart to be adjusted as needed, avoiding the limitation of the width of rural roads during use and meeting usage requirements.

[0017] 2. This type of agricultural handcart with adjustable wheelbase features a reinforced structure, an outer support rod, a limiting block, and an inner support rod. During installation, the inner support rod is first rotated to extend it to a suitable position.
