1. A collapsible wing assembly of an unmanned aerial vehicle (UAV) having a fuselage, the assembly comprising: a centre wing adapted to be attached to the fuselage; anda pair of outboard wings,wherein each of the outboard edges of the centre wing comprises a first attachment structure having at least a pair of L-shaped profile locks, and each of the inboard edges of the outboard wings comprises a second attachment structure having at least a pair of locking pins,wherein each of the L-shaped profile locks comprises a hollow channel having a first arm pointing towards a bottom surface of the centre wing, and a second arm, inclined to the first arm, pointing towards a trailing edge of the centre wing,wherein each of the L-shaped profile locks of the first attachment structure is operable to engage with a respective locking pin of the second attachment structure and displace the locking pin to a captive position towards the trailing edge of the centre wing. 2. The assembly of claim 1, wherein the centre wing comprises a body and a centre wing adaptor mounted to an outboard edge of the body, and wherein the outboard wing comprises a body and an outboard wing adaptor mounted to an inboard edge of the body of the outboard wing, wherein the first attachment structure is provided on an end face of the centre wing adaptor, and the second attachment structure is provided on an end face of the outboard wing adaptor. 3. The assembly of claim 2, wherein airfoils of the centre wing adaptor and outboard wing adaptor match respectively to those of the bodies of the centre wing and the outboard wing. 4. The assembly of claim 2, wherein the centre wing adaptor and the outboard wing adaptor are removably mounted respectively to the centre wing and the outboard wing. 5. The assembly of claim 2, wherein one of the L-shaped profile locks is located proximate to a leading edge of the centre wing adaptor and the other is located proximate to a trailing edge of the centre wing adaptor, wherein one of the locking pins is located proximate to the leading edge of the outboard wing adaptor and the other is located proximate to the trailing edge of the outboard wing adaptor. 6. The assembly of claim 1, wherein the first arm is substantially perpendicular to the second arm. 7. The assembly of claim 1, wherein the bottom surface of the centre wing has a pair of openings corresponding to respective openings of the first arm. 8. The assembly of claim 1, wherein a top surface of the centre wing has a slot, positioned above the first arm of the L-shaped profile lock, for receiving a locking key to lock any relative movement of the centre wing and outboard wing in the captive position. 9. The assembly of claim 7, wherein the dimension of a head of the locking pin matches with that of the openings of the first arm of the hollow channel of the L-shaped profile lock, and the dimension of a stem of the locking pin matches with that of the second arm of the hollow channel of the L-shaped profile lock. 10. The assembly of claim 2, wherein an opposing face of the centre wing adaptor and outboard wing adaptor comprises one or more anchors for mounting the centre wing adaptor and outboard wing adaptor respectively to an outboard edge of the centre wing and an inboard edge of the outboard wing. 11. The assembly of claim 8, wherein the locking key comprises a head and a base, wherein the top surface of the head has an inclination to match the top surface of the centre wing, wherein the base has a slit and a resilient arm, the resilient arm comprising a stepped portion comprising a plurality of inclined steps terminating at the head. 12. The assembly of claim 11, wherein in a locked position, the stepped portion is operable to grip the stem of the an adjacent locking pin in order to lock any relative movement of the centre wing and the outer wing, and the base of the locking key locks with the opening found on the bottom surface of the centre wing. 13. The assembly of claim 9, wherein the body of the locking key comprises a slot for inserting a securing pin in order to secure the locking pin to the centre wing. 14. A method of locking a collapsible wing assembly of an unmanned aerial vehicle (UAV) having a fuselage, the method comprising the steps of: providing a centre wing adapted to be attached to the fuselage;providing a pair of outboard wings;providing a first attachment structure to each outboard edges of the centre wing, the first attachment structure having at least a pair of L-shaped profile locks, wherein each of the L-shaped profile locks comprises a hollow channel having a first arm pointing towards a bottom surface of the centre wing, and a second arm, inclined to the first arm, pointing towards a trailing edge of the centre wing;providing a second attachment structure to each inboard edges of the outboard wings, the second attachment structure having at least a pair of locking pins;engaging each of the L-shaped profile locks of the first attachment structure with a respective locking pin of the second attachment structure; and displacing the locking pin to a captive position towards the trailing edge of the centre wing. 15. The method of claim 14, wherein the centre wing comprises a body and a centre wing adaptor mounted to an outboard edge of the body, and wherein the outboard wing comprises a body and an outboard wing adaptor mounted to an inboard edge of the body of the outboard wing, wherein the first attachment structure is provided on an end face of the centre wing adaptor, and the second attachment structure is provided on an end face of the outboard wing adaptor. 16. The method of claim 15, further comprising a step of inserting a locking key into a slot provided on the centre wing adaptor to lock the relative movement of the centre wing and the outboard wing. 17. A method of unlocking the collapsible wing assembly locked by the method of claim 16, the method comprising the steps of: releasing the locking key;holding the centre wing and moving the outboard wing towards the leading edge of the centre wing; andmoving the outboard wing downward to release the outboard wing.
