• at least one elastic element, wherein the at least one elastic element has one end pressing against a wall portion of the accommodating slot and an opposite end pressing against the engaging block;
• and
• a connecting portion adjacent to the accommodating slot and surrounding the outer surface of the rod;
• and
• a sleeve connected to the rod, the sleeve having an inner surface comprising:
• a first ratchet portion;
• a second ratchet portion;
• and
• a non-ratchet portion located between the first ratchet portion and the second ratchet portion;
