5. The adjusting device according to claim 1 , wherein the first portion comprises a first opening and a second opening, wherein the first opening comprises a locking surface, wherein

the adjusting portion comprises a first locking device comprising a locking surface, wherein the first locking device is adapted to be arranged in the first opening, and further adapted to releasably engage with the locking surface of the first opening, a second locking device comprising a locking surface wherein the second locking device is adapted to be arranged in the second opening, wherein the center axis of the second locking device forms a pivot axis wherein the adjusting portion is biased in a locking position by a biasing device, wherein the biasing device comprises a biasing portion and a first spring device, wherein the biasing portion is pivotally arranged on the first portion, wherein the biasing portion comprises a locking surface, wherein the second locking device is further adapted to releasably engage with the locking surface,

wherein the adjusting portion is adapted to rotate around the pivot axis upon actuation of the adjusting portion, whereby the first locking device disengages from the locking surface of the first opening and the second locking device disengages from the locking surface of the biasing portion, whereby the adjusting portion moves towards the release position for enabling adjusting of the adjusting portion in relation to the first portion in a direction parallel to the pivot axis.

6. The adjusting device according to claim 1 , wherein the adjusting portion further comprises a retaining device-, wherein the first locking device and second locking device and pivot shaft, is fixedly arranged in the retaining device.

7. The adjusting device according to claim 1 , wherein the first opening and second opening are shaped to partially encompass the circumference of the first locking device and second locking device at a respective locking portion, wherein the locking portions comprises the locking surfaces of the first portion.

8. The adjusting device according to claim 1 , wherein the first opening and second opening are shaped to enable the movement of the first locking device and second locking device in a release direction out of and away from the locking portions of the first and second openings, to a release position of the adjusting portion upon rotation of the adjusting portion around the pivot axis.

9. The adjusting device according to claim 1 , wherein the first locking device and second locking device are elongatedly shaped to extend in a main extension direction, wherein the main direction is parallel to the pivot axis when the first and second locking devices and pivot shaft are arranged in the respective first opening-, second opening and third opening.

10. The adjusting device according claim 1 , wherein the locking surfaces comprises locking teeth or grooves.

11. The adjusting device according to claim 10 , wherein the locking teeth or grooves of the locking devices and the first and second openings are shaped as alternately increased and reduced radii portions adapted to matingly engage with each other, wherein the height of the radii portions in the main extension direction of the locking devices and holes, parallel to the pivot axis defines the adjusting steps of the adjusting device.

12. The adjusting device according to claim 11 , wherein the radii of the locking teeth or grooves of the locking devices and/or the openings are shaped such that the adjusting portion requires a rotation of 1-10° around the pivot point, to move from a locking position to a release position.
