The control box includes a self-propelled trigger unit including a self-propelled control switch S, a lever and a control handle matching with the self-propelled control switch S; and a casing being provided with a receiving cavity. The self-propelled triggering unit is at least partially disposed in the receiving cavity. The lever abuts and triggers the self-propelled control switch S when the control handle is pulled to abut the lever and the control handle swings up and down in a plane where a side wall of the casing is located. The control box has reasonable switch distribution and is easy to operate.
