Abstract
A depth limiting device for a drill includes a main body, an axial braking structure, and a limited shrinking structure. The axial braking structure is attached to the main body. The limited shrinking structure surrounds a drill rod of the drill, is slidably attached to the main body, and is in a home position or a compressed position. The axial braking structure axially brakes the drill rod such that the drill rod moves together with the depth limiting device. When the drill rod enters into a subject, the limited shrinking structure is pressed against the subject, moves from the home position to the compressed position, and stops the drill rod from entering further into the subject.
Claims17
A depth limiting device for a drill, comprising:
- a main body;
- an axial braking structure, the axial braking structure being attached to the main body;
- a limited shrinking structure, the limited shrinking structure surrounding a drill rod of the drill, being slidably attached to the main body, and being in a home position or a compressed position;
- and
- a structure adapted for pushing the limited shrinking structure to the home position,
- wherein the axial braking structure axially brakes the drill rod such that the drill rod moves together with the depth limiting device, and
- wherein when the drill rod enters into a subject, the limited shrinking structure is pressed against the subject, moves from the home position to the compressed position, and stops the drill rod from entering further into the subject.
