Abstract

The invention relates to a blade receiver assembly, comprising a switch comprising a switch cover and a switch base fixedly connected to each other, wherein the switch base has an opening; an axle with a structural section and a body receiver section, wherein the axle is arranged to move through the opening of the switch base in relation to the switch. The invention also relates to a cutting device comprising a blade receiver assembly.

First claim

The invention claimed is:

1. A blade receiver assembly, comprising:
a switch comprising a switch cover and a switch base connected to each other forming an inner space, wherein the switch base comprises an opening;
a flippable arc pivotally coupled to the switch cover;
an axle, having an axis, and comprising a structural section and a body receiver section, wherein the structural section is provided at least partially within the switch and the body receiver section is provided outside the switch;
a spring provided inside the inner space of the switch;
and a magnet is incorporated in the structural section of the axle, wherein the magnet is arranged at a distance away from the axis of the axle;
wherein the axle is movable against a spring force of the spring through the opening of the switch base in relation to the switch, the spring force biases away an end surface of the axle facing toward the switch cover from contacting an inner surface of the switch cover.

2. The blade receiver assembly according to claim 1 , wherein the spring is connected to the axle allowing the axle to move along an axis of the axle against the spring force.

3. The blade receiver assembly according to claim 1 , wherein the structural section has a bigger diameter than the body receiver section.

4. The blade receiver assembly according to claim 1 , wherein the blade receiver assembly further comprises a bearing, and the switch base comprises a corresponding an opening for said bearing.

5. The blade receiver assembly according to claim 1 , wherein the body receiver section comprises a twist-lock.

6. The blade receiver assembly according to claim 1 , wherein the switch cover comprises a step supporting the spring, wherein the spring surrounds the step.

7. The blade receiver assembly according to claim 1 , wherein the axle comprises a flange at the structural section to prevent the axle from falling off the switch.

8. The cutting device according to claim 1 , wherein the flippable arc comprises inner protrusions configured to fit and rotate inside holes in the switch cover.

9. A cutting device, comprising:
a body comprising a handle and a blade assembly holding member;
a rotary blade;
a blade receiver assembly, the blade receiver assembly comprising:
a switch comprising a switch cover and a switch base connected to each other forming an inner space, wherein the switch base has an opening;
a flippable arc pivotally coupled to the switch cover;
an axle with a structural section and a body receiver section and having an axis, wherein the structural section is provided at least partially within the switch and the body receiver section is provided outside the switch,
a spring provided inside the inner space of the switch;
and a magnet is incorporated in the structural section of the axle, wherein the magnet is arranged at a distance away from the axis of the axle;
the axle is movable against a spring force of the spring through the opening of the switch base, the spring force biases away an end surface of the axle facing toward the switch cover from contacting an inner surface of the switch cover, and the body receiver section is releasably connectable to the blade assembly holding member.

10. The cutting device according to claim 9 , wherein the rotary blade is arranged to fit and rotate between the body receiver section and the switch base.

11. The cutting device according to claim 9 , wherein the spring is connected to the axle and arranged partially inside the axle.

12. The cutting device according to claim 9 , wherein the spring is connected to the axle and arranged to partially surround the axle.

13. The cutting device according to claim 9 , wherein a surface of the magnet is at the same plane as the switch base when the spring connected to the axle is not in a compressed position.

14. The cutting device according to claim 9 , wherein the rotary blade is rotatably arranged on the axle between the magnet and the body receiver section, wherein the magnetic force attracts and prevents the rotary blade from sliding off the axle.

15. The cutting device according to claim 9 , wherein the axle is arranged to slide along its axis, when the spring connected to the axle is compressed allowing a distance between the magnet and the rotary blade to increase and the magnetic force to weaken.

16. The cutting device according to claim 9 , wherein the switch is rotatable, and the body receiver section comprises a twist-lock arranged to lock onto the blade assembly holding member in one position, and releasably slide in/out the blade assembly holding member in another position.

17. The cutting device according to claim 9 , wherein the switch cover comprises a step supporting the spring.

18. The cutting device according to claim 9 , wherein the structural section comprises a flange arranged to prevent the axle from falling off the switch.

19. The cutting device according to claim 9 , wherein the flippable arc defines a smooth curve.

20. The cutting device according to claim 9 , wherein the flippable arc defines an angular curve.
