This utility model discloses a manual / automatic triggering device, including a device body, a manual operating mechanism, and an automatic trigger. The manual operating mechanism includes a movable contact component and an operating end. The device body includes a limiting window and a slider. The slider is placed in the limiting window. The movable contact component and the operating end are connected by the slider. When the operating end slides, it causes the movable contact component to contact the automatic trigger, and the automatic trigger is activated. When the operating end slides, it causes the movable contact component to separate from the automatic trigger, and the automatic trigger is deactivated. The limiting window limits the slider, allowing the movable contact component to continuously trigger the automatic trigger.
