Abstract
A device is arranged to be able to provide openings in a body. The device comprises a cutting head having a front and a rear. The cutting head is provided with a cutting device; a power transmission body arranged to be able to transmit power from a driving means to the cutting device; a drive unit holder, wherein the drive unit holder is adapted to be able to be arranged at a distance (A3) from the rear of the cutting head; at least one connecting body having a first and a second end portion, wherein the connecting body connects the cutting head to the drive unit holder; and a support arranged to be able to rotatably hold the device on a body.
Claims21
A device for providing openings in a body, wherein the device comprises:
- a cutting head having a front and a rear, wherein the cutting head is provided with a cutting device;
- a power transmission body arranged to be able to transmit power from a driving means to the cutting device;
- a drive unit holder, wherein the drive unit holder is arranged at a distance (A3) from the rear of the cutting head;
- at least one connecting body having a first and a second end portion, wherein the connecting body connects the cutting head to the drive unit holder;
- and
- a support arranged to be able to rotatably hold the device on a body, where a distance (A1) between the first end portion of the connecting body and the rotation axis (D1) is smaller than or the same as the distance (A2) between the front of the cutting head and the rotation axis (D1).
The device according to claim 7, wherein the support is constituted by a pointed body.
A method for cutting openings in a body via a device that comprises
- a cutting head having a front and a rear, wherein the cutting head is provided with a cutting device;
- a power transmission body arranged to be able to transmit power from a driving means to the cutting device;
- a drive unit holder, wherein the drive unit holder is arranged at a distance (A3) from the rear of the cutting head;
- at least one connecting body having a first and a second end portion, wherein the connecting body connects the cutting head to the drive unit holder;
- and
- a support arranged to be able to rotatably hold the device on a body, where a distance (A1) between the first end portion of the connecting body and the rotation axis (D1) is smaller than or the same as the distance (A2) between the front of the cutting head and the rotation axis (D1);
- the method comprising:
- A) positioning the support at a desired distance from the cutting device;
- B) fastening the support at a desired distance relative to the cutting device;
- C) activating the power transmission body via a driving means;
- and
- D) moving the cutting head along a cutting line around the rotation axis (D1).
