The invention relates to a micro single-row hand-held combined garlic harvester. The double limit wheel structure is adopted to guarantee the proper digging depth of an excavating knife during work; an alignment and cutting integrated device is adopted to make the structure simple and compact, and consistency of cutting is guaranteed; a series cross hollow reversing device is utilized, the workingpart and the forward direction forms a certain angle, so the line of sight of an operator is not affected when the work is advanced; a walking universal wheel assembly is only used during walking onthe road and is taken down during work; a main clamping transmission mechanism is composed of a series cross hollow reversing mechanism matched with a retractable cross universal joint, and a power system can simultaneously drive the main clamping transmission mechanism and an alignment and cutting mechanism for work. The harvester is advantaged in that the structure is compact, weight is light, cost is low, the harvester is suitable for small-scale garlic plantation users for purchase and use, and great social and economic values are achieved.
