Abstract
The invention provides a kind of compasses. The compasses comprise a foot, wherein a piece of chalk is additionally arranged to the foot. Two compasses bar of the compasses are respectively provided with a telescopic thin bar in a sleeved mode, adjusting bolts used for adjusting and fixing the telescopic thin bars are arranged on the connection portions of the two compasses bars and the telescopic thin bars. Due to the fact that the telescopic thin bars are installed on the two compasses bars in the sleeved mode, when the compasses are used, the required length can be adjusted according to the requirements, and the compasses are more convenient to use for teaching.
