The present invention is to provide a lever-type liquid injecting device or which can automatically perform locking in a spray or injection type of a lever, and can change the spray or injection type without suspending a spraying operation. In the lever-type liquid injecting device of the present invention, an open and close valve (7) and a rectifier valve (8) are installed on the way of a liquid supply path (5) provided in a main body (3), the open and close valve (7) is opened by a lever (6), an opening degree of the rectifier valve (8) is changed, and a form of injection water flow from a nozzle unit (4) is changed. A multi-stage locking mechanism (41) capable of holding the operated level (6) at multiple positions with different opening degrees of the open and close valve (7) is provided, and the multi-stage locking mechanism includes a coupling unlocking means which unlocks coupling of a latch claw to a locking claw at a position of maximally gripping the lever (6), and an induction means which induces the lever at the position of maximally gripping while keeping the latch claw in an unlocking posture so as not to be coupled to the locking claw, when the lever is returned to a predetermine position by releasing the gripping. |
