Dependent claims

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;
