• the third body assembly covers the indication unit which is moved in the third body assembly;
• the second locking set is assembled with the first body and is rotatable relative to the first locking set;
• the second locking set includes a second locking member, a first positioning member, a ring, and a second positioning member;
• the second locking member is fit into the second receiving chamber, so that the second locking member is secured to and rotated with the first body;
• the second locking member is provided with a first perforation aligning with one of the positioning channels;
• the second locking member has an outer face provided with a first annular groove;
• the first annular groove is provided with two retaining holes;
• the second locking member is provided with a second perforation aligning with one of the positioning channels;
• the second perforation aligns with the first perforation;

• the ring is mounted on the first annular groove and the second annular groove;
• the ring has two retaining portions formed on two ends thereof;
• the two retaining portions are retained in the two retaining holes so that the ring is secured to the second locking member;
• the first positioning member is limited by the ring;
• the second positioning member is received in the second perforation;
• the third locking set is assembled with the first body and the second locking set;
• the third locking set is operable between a locking position where the third locking set restricts the second locking set and the first locking set so that the first body cannot be rotated relative to the second body and an unlocking position where the third locking set releases the second locking set and the first locking set so that the first body is rotated relative to the second body;
• the third locking set is moved relative to the first body so that a distance is defined between the third locking set and the first body;
• the third locking set includes a third locking member, a control ring, and a second elastic member;
• the third locking member is assembled with the first body and moved and rotated relative to the first body;
• the third locking member is provided with a plurality of second positioning portions aligning with the first positioning portions;
• the third locking set is disposed at the locking position when the second positioning portions engage the first positioning portions and disposed at the unlocking position when the second positioning portions disengage the first positioning portions;
• the third locking member has an interior provided with a fifth receiving chamber;
• the control ring is secured to the third locking member and moved and rotated with the third locking member;
• the first positioning member, the ring, and the second positioning member are hidden in the control ring;
• the control ring is moved and rotated on the second locking member;
• the control ring has an inner face provided with a first recessed portion and a second recessed portion;
• each of the first recessed portion and the second recessed portion has an arcuate concave shape and has a minimum position and a maximum position;
• the second elastic member is received in the third locking member and elastically biased against the third locking member or the control ring;
