A quick connection anti-loose apparatus, comprising:
- a first main rod,
- a second main rod, and
- a connection anti-loose device, for connecting the first main rod and the second main rod;
- wherein the connection anti-loose device comprises
- a first joint, provided on the first main rod;
- a second joint, provided on the second main rod;
- and
- a connecting structure, slidably sleeved on the first joint and restricted from slipping off from an end of the first joint facing the second joint, or slidably sleeved on the second joint and restricted from slipping off from an end of the second joint facing the first joint;
- and
- further comprises anti-rotation structures, provided between opposite ends of the first joint and the second joint, and combined with each other to prevent the first joint and the second joint from rotating relative to each other;
- the connecting structure is adapted for sliding from the first joint or the second joint on which the connecting structure is sleeved to the second joint or the first joint, and driving the first joint or the second joint on which the connecting structure is sleeved to slide during detachable connection with the second joint or the first joint, so as so enable the anti-rotation structures between the opposite ends of the first joint and the second joint to be combined with each other.
