Driving head of an electric gardening machine

A driving head of an electric gardening machine,

• a base, defining an axial direction;
• a driving assembly, disposed on the base, including a motor assembly and a driving rod, the motor assembly and the driving rod being in a rotation-connecting relationship, the driving rod including at least one first groove which extends toward the axial direction and is disposed on a circumferential wall of the driving rod;
• a clutch member, being 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, an elastic member being elastically abutted against and between the clutch member and the driving assembly and biasing the clutch member toward the first position, the clutch member including at least one second groove which extends toward the axial direction and is disposed on a circumferential wall of the clutch member, between one of the at least one first groove and one of the at least one second groove being a restricting member movably received therewithin;
• a transmission member, being rotatably connected to the base, having a tool assembly which is co-movable with the transmission member, the clutch member being in rotational interference with and engaged with the transmission member when the clutch member is located in the first position, the clutch member being free of rotational interference with the transmission member when the clutch member is located in the second position;
• wherein when the clutch member is located in the first position and the tool assembly is interfered to be non-rotatable relative to the base, and the transmission member cannot be rotated and the driving rod continues to rotate, the at least one first groove guides the restricting member to move relative to the at least one first groove and the at least one second groove, and the clutch member is moved to the second position and driven by the driving rod.
