• the first mounting portion is a noncircular recess;
• the second body is provided with two third faces formed on two ends of the second body;
• each of the two third faces has a planar shape and is flush with the first face of one of the two first receiving grooves;
• the two third body modules are mounted on the first slot;
• the two third body modules are moved in the first slot linearly and simultaneously to be close to or away from the second body;
• one of the two third body modules is mounted on the first end, and the other one of the two third body modules is mounted on the second end;
• the two third body modules are arranged symmetrically relative to the first body;
• each of the two third body modules includes a first locking member, a second locking member, a first elastic member, and a first push member;
• the first locking member is received in one of the two first receiving grooves and moved linearly on the first face;
• the first locking member is provided with a first locking portion close to the first mounting portion;
• the first locking portion is a flange with a concave face;
• the first locking portion is provided with a first inclined face directed outward relative to the first body;
• the first inclined face of one of the two third body modules is directed toward an outside of the first end, and the first inclined face of the other one of the two third body modules is directed toward an outside of the second end;
• the first inclined faces of the two third body modules are arranged symmetrically relative to the first body;
• the first locking member is provided with a second mounting portion that is distant from the first locking portion and penetrates the first locking member;
• the second mounting portion is a noncircular groove;
• the first locking member is provided with two fourth faces aligning with and sliding relative to the two second faces;
• the first locking member is provided with a third mounting portion penetrating the first locking member and connected to the second mounting portion;
• the third mounting portion is a noncircular groove;
• the second locking member is assembled with the first locking member and provided with a fourth mounting portion;
• the fourth mounting portion is mounted in the second mounting portion so that the second locking member and the first locking member are moved simultaneously;
• the fourth mounting portion is movably mounted in the first slot and hidden in the first body;
• the second locking member is provided with a second receiving groove having an opening directed toward a direction opposite to the second body;
• the fourth mounting portion has a distal end provided with a first hooked portion;
• the second locking member is provided with a second hooked portion;
• the second hooked portion of one of the two third body modules is hooked with the first hooked portion of the other one of the two third body modules so that the two third body modules are assembled;
• the second locking member is provided with a fifth mounting portion mounted in the third mounting portion;
• the second locking member is provided with a first projection;
• the first projection is a protruding block;
• the first elastic member is received in the second receiving groove to provide a restoring effect to each of the two third body modules;
• the first push member is assembled with the first elastic member and received in the second receiving groove;
• the first elastic member is elastically biased between the second receiving groove and the first push member;
• the first push member has an end pressing an inner peripheral face of the first slot;
• the fourth body is a box-type hand tool;
• the fourth body is provided with a sixth mounting portion mounted in or released from the first mounting portion;
• the sixth mounting portion is a noncircular shank;
• the fourth body is provided with a first annular groove and a second annular groove;
• the sixth mounting portion is arranged between the first annular groove and the second annular groove;
• the first locking member of each of the two third body modules is locked in the first annular groove or the second annular groove;
• the first annular groove and the second annular groove have the same diameter and the same structure;
• the fourth body has an end provided with a second inclined face;
• the fourth body is provided with a first peripheral face having a diameter more than that of the first annular groove;
• the first peripheral face has an annular shape;
• the fourth body is provided with a first locking face having a planar shape;
• the fourth body is provided with a third inclined face;
• the third inclined face and the second inclined face are directed in the same direction;
• the fourth body is provided with a second locking face having a planar shape;
• and
• the second inclined face, the first peripheral face, the first locking face, the first annular groove, the third inclined face, the sixth mounting portion, the second locking face, and the second annular groove are arranged serially on the fourth body from top to bottom.
