• and
• a working head having a body;
• a column connected to one side of the body;
• and a pivotal block extending outward from another side of the body, the body being provided with two flaps by two sides of the pivotal block, the two flaps being parallel to the pivotal block, a gap being provided between each of the two flaps and the pivotal block, and the two ears of the main body being pivotally disposed in the gaps between the two flaps and the pivotal block respectively;
• wherein each ear of the two ears is located directly between and adjacent to the pivotal block and a corresponding flap of the two flaps;
• wherein the two ears, the pivotal block and the two flaps are stacked together and present a five-layer staggered structure defined by a first flap of the two flaps, a first ear of the two ears, the pivotal block, a second ear of the two ears, and a second flap of the two flaps located directly adjacent to one another, respectively, and pivotally connected together;
