摘要： A driving head of an electric gardening machine includes a base, a driving assembly, a clutch member and a transmission member. The base defines an axial direction. The driving assembly is disposed on the base and includes a motor assembly and a driving rod. The motor assembly and the driving rod are in a rotation-connecting relationship. The clutch member is sleeved with the driving rod and slidable relative to the driving rod in the axial direction to be in a first position or a second position. The transmission member is rotatably connected to the base. The clutch member is in rotational interference with and engaged with the transmission member when the clutch member is located in the first position. The clutch member is free of rotational interference with the transmission member when the clutch member is located in the second position.
