Two hooks (30) are respectively connected to the inner tube (100) and the outer tube (10) so that when the sleeves are pulled, the locking plates (40) are moved away from the hooks (30) so as to hook the seat post and the handlebar stem of a bicycle. Each of the two sleeves are positioned by a resilient member (16).",
