A hooking device includes a hook for clasping a latching device, a spring mounted to the hook for providing a restoration force to the hook, and a base securing the hook and the spring thereon. The hook includes a main portion, a catch portion, and a pair of shaft portions extending from the other end along opposite direction. The spring includes two winding portions, two first arms extending from ends of the winding portions, the first arms acting on the hook; and two second arms extending from the other ends of the winding portions. The base includes a base plate defining an opening, two supporting plates accommodating the shaft portions, two bearing plates extending from the base plate, the second arms acting on the bearing plate, and an elastic arm extending from the base plate pushing on the other end of the main portion of the hook.

What is claimed is: 1. A hooking device for connecting devices together, comprising: a hook, the hook comprising: a main portion; a catch portion which is formed at an end of the main portion; and a pair of shaft portions being formed at the other end of the main portion, the shaft portions defining an axis direction around which the hook rotates; a spring mounted to the hook for providing a restoration force to the hook when the hook is rotated around the axis direction, the spring comprising: a pair of winding portions sleeved on the respective shaft portions; and a first arm and a second arm respectively extending from two ends of the winding portions, one of the first arm and the second arm being attached to the hook; and a base securing the hook and the spring thereon, the base comprising: a base plate which defines an opening therein to allow the catch portion and part of the main portion of the hook to protrude therethrough; a pair of supporting plates perpendicularly extending from the base plate, to accommodate the shaft portions therein; a bearing plate perpendicularly extending from and located below the base plate, the other one of the first arm and the second arm resisting against the bearing plate; and an elastic arm extending from the base plate, the elastic arm pushing the other end of the main portion of the hook. 2. The hooking device as claimed in claim 1, wherein the hook forms a baffle portion on the main body positioning the one of the first arm and the second arm attached to the hook, and the baffle portion perpendicularly extends from the main body. 3. The hooking device as claimed in claim 1, wherein the main portion of the hook defines a slot which receives therein the one of the first arm and the second arm attached to the hook. 4. The hooking device as claimed in claim 1, wherein the base plate defines a pair of accommodating notches that receive the shaft portions therein. 5. The hooking device as claimed in claim 4, wherein a pair of guiding surfaces are formed on the base plate, and the guiding surfaces communicate with respective accommodating surfaces surrounding the accommodating notches. 6. The hooking device as claimed in claim 5, wherein the guiding surfaces are at an oblique angle with respect to the base plate, and at an opposite side to the elastic arm with respect to the shaft portions. 7. The hooking device as claimed in claim 1, wherein the spring comprises a pair of resisting portions and a pair of holding portions, and the resisting portions and the holding portions are bent with respect to the other arm of the first arm and the second arm. 8. The hooking device as claimed in claim 7, wherein the resisting portions resist on the bearing plate, and the holding portions hold the base plate. 9. The hooking device as claimed in claim 8, wherein the bearing plate defines a recess accommodating the holding portions therein. 10. The hooking device as claimed in claim 1, wherein the elastic arm comprises a fixing portion and a pushing portion, the fixing portion connects to the base plate, and the pushing portion pushes on the other end of the main portion of the hook. 11. The hooking device as claimed in claim 10, wherein the elastic arm comprises a strengthening rib, and the rib is formed at a middle of the fixing portion and extends to the pushing portion. 12. The hooking device as claimed in claim 1, wherein the hook is integrally formed. 13. A hooking device for connecting devices together, comprising: a hook, the hook comprising: a main portion; a catch portion formed at one end of the main portion; and a pair of shaft portions extending from the other end of the main portion along opposite directions, the shaft portions defining an axis direction of the hook around which the hook rotates; a spring mounted to the hook for providing a restoration force to the hook when the hook is rotated around the axis direction, the spring comprising: a pair of winding portions sleeved on the shaft portions of the hook; and a pair of first arms extending from ends of the winding portions, the first arms acting on the hook; and a pair of second arms extending from the other ends of the winding portions; and a base securing the hook and the spring thereon, the base comprising: a base plate defining an opening therein to allow the catch portion of the hook to protrude therethrough; a pair of supporting plates extending from the base plate accommodating the shaft portions; a pair of bearing plates perpendicularly extending from and located below the base plate, the second arms acting on the bearing plates; and an elastic arm extending from the base plate pushing on the other end of the main portion of the hook. 14. The hooking device as claimed in claim 13, wherein the elastic arm comprises a fixing portion and a pushing portion, the fixing portion connects to the base plate, and the pushing portion pushes on the other end of the main portion of the hook. 15. The hooking device as claimed in claim 14, wherein the elastic arm comprises a strengthening rib, and the rib is formed at a middle of the fixing portion and extends to the pushing portion. 16. The hooking device as claimed in claim 13, wherein the spring includes a pair of resisting portions and a pair of holding portions, and the resisting portions and the holding portions are bent with respect to the other arm of the first arm and the second arm. 17. The hooking device as claimed in claim 16, wherein the spring comprises a connecting portion connecting the first arms. 18. The hooking device as claimed in claim 16, wherein the hook forms a baffle portion on the main portion positioning the connecting portion of the spring, and the baffle portion perpendicularly extends from the main body. 19. The hooking device as claimed in claim 16, wherein the main portion defines a slot therein accommodating the connecting portion of the spring therein. 20. The hooking device as claimed in claim 13, wherein the hook is integrally formed.
