ABSTRACT:
A cutting device includes an upright post, a hollow tool carrier mounted swingably on the post, a cutting tool mounted rotatably on the tool carrier, and a cover member mounted pivotally to the tool carrier so as to cover a portion of the cutting tool. A moving device is employed for moving the cover member, and includes a stationary base which extends into the tool carrier and which is formed with an elongated guide slot, and an L-shaped lever which is disposed in the tool carrier and which has an upper portion, a lower portion that engages slidably the guide slot, and an angled intermediate portion that is disposed between the upper and lower portions and that is mounted pivotally to the tool carrier. A curved link is disposed in the tool carrier and has two opposite ends pivoted respectively to the cover member and the upper portion of the L-shaped lever. Downward swinging movement of the tool carrier on the post results in corresponding movement of the lower portion of the L-shaped lever along the guide slot to cause the L-shaped lever to pivot inside the tool carrier and pull the curved link. The cover member is moved swiftly from a covering position to an uncovering position, wherein the portion of the cutting tool is exposed from the tool carrier.
