Blade guard device for a sawing machine
 A blade guard device for a circular sawing machine includes an upper guard having a lower end pivotally mounted on a stationary base and an upper end including a handle, a circular saw rotatably mounted on the upper guard, an elongated pressing lever pivotally mounted on a locating plate and having a curved operation surface including a projection, an inclined section, and a lower bent section, a pressing roller secured on the upper guard and slidably engaging the curved operation surface of the pressing lever, a link secured to the pressing lever, a circular mounting plate secured to the link and rotatably mounted on the upper guard, and a lower guard secured to the circular mounting plate for covering the circular saw. In such a manner, when the handle is moved downward, the upper guard is pivoted downward to move the pressing roller to press the projection of the pressing lever, thereby moving the link which largely pulls the circular mounting plate for rapidly rotating the circular mounting plate which rapidly rotates the lower guard upward, thereby rapidly exposing a lower part of the circular saw.
