Abstract
The utility model relates to a lengthening device for a pencil. The utility model is characterized in that the lengthening device is cylindrical, the diameter is slightly larger than the diameter of a pencil and a shaft rod which is connected by screw threads of the lengthening device is arranged near both ends of the cylindrical lengthening device transversally. Because the utility model is in a cylinder shape, in the way, the head of the pencil can be put in both ends of the cylindrical lengthening device. Because a screw rod for tightly clamping the head of the pencil is arranged on both ends of the lengthening device, the pencil can be fixed by clamping by the screw rod tightly after the head of the pencil is arranged on the lengthening device. Thus, the head of the pencil can be used continuously and the purpose of the invention of the utility model is achieved.
