Embodiment Construction
[0016] Such as figure 1 As shown, an infinitely extending energy-saving pencil includes a pencil. The two ends of the pencil 1 are made of a trapezoidal thread 11 with a length of 2-4 cm. The rising angle of the thread 11 is smaller than the equivalent friction angle. The diameter is smaller than the diameter of the pencil 1 by 0.2-2 mm, and the middle section of the thread 11 is provided with a stop groove 12 slightly deeper than the thread groove.
[0017] Such as figure 2 , 3 As shown, the connecting piece 2 is provided with an internal thread 21. The lift angle of the thread 21 is smaller than the equivalent friction angle, and it is matched with the thread 11 on the end of the pencil 1. The two ends of the connecting piece 2 are each provided with a pair of one end fixed to the other end is free The movable elastic buckle 22 is positioned when the buckle 22 is engaged with the stop groove 12 when the connecting member 2 moves. The outer walls of the two ends of the connecti...
