Abstract:
A drill bit with chamfering function has a body, a chamfering blade, an abutting rod, an elastic element, an adjusting element, and a drill bit. The body is a hollow tube, and has an internal space, a blade opening, a pivot segment, and a connecting end. The chamfering blade is pivotally connected to the body, selectively extends out of the blade opening, and has a blade portion, a blade pivot portion, and an abutting portion. The abutting rod is disposed in the internal space and abuts against the abutting portion. The elastic element is disposed in the internal space and is compressed between the abutting rod and the adjusting element. The adjusting element is disposed in the internal space for adjusting an amount of compression of the elastic element. The drill bit is securely connected to the connecting end of the body.

Claim (Index 1):
A drill bit with chamfering function comprising:\n a body being a hollow tube, and having\n a bottom; \n an external surface; \n an internal space formed in the body; \n a blade opening formed through the external surface of the body adjacent to the bottom of the body, and communicating with the internal space; \n a pivot segment disposed on the external surface of the body adjacent to the blade opening, and extending through the internal space; and \n a connecting end disposed on the bottom of the body; \n a chamfering blade pivotally connected to the body in the internal space, selectively extending out of the blade opening of the body, and having\n a front end selectively extending out of the blade opening of the body; \n a rear end; \n a blade portion disposed on the front end of the chamfering blade, and having\n a first blade edge obliquely disposed on the front end of the chamfering blade; \n a second blade edge obliquely disposed on the chamfering blade toward the first blade edge; and \n a rounded portion disposed on the chamfering blade between the first blade edge and the second blade edge; \n \n a blade pivot portion disposed on the chamfering blade between the blade portion and the rear end of the chamfering blade, pivotally disposed on the pivot segment to enable the chamfering blade to rotate relative to the body by the pivot segment and having a cutting position and a non-cutting position; and \n an abutting portion disposed on the rear end of the chamfering blade and being a recess; \n wherein the chamfering blade is located on the cutting position, the blade portion extends out of the body via the blade opening, and the chamfering blade is located on the non-cutting position, the blade portion is disposed in the internal space of the body; a pushing rod disposed in the internal space of the body via the top of the body, and having\n a front end; and \n a pushing cone disposed on the front end of the abutting rod and abutting against the abutting portion of the chamfering blade; \n an elastic element disposed in the internal space of the body; an adjusting element disposed in the internal space of the body, being opposite to the connecting end, hold the elastic element between the abutting rod and the adjusting element for adjusting a amount of compression of the elastic element; and a drill bit securely connected to the body at the connecting end of the body, and having an outer diameter larger than an outer diameter of the body; wherein no external force is pressed the chamfering blade, the adjusting element adjusts the compression amount of the elastic element so that the abutting rod press the chamfering blade at the cutting position, and the rounded portion of the chamfering blade is pressed by a lateral pressure greater than the pressure of the elastic element, the chamfering blade is rotated to the non-cutting position.
