Abstract

The invention discloses an adjustable matts scriber for teaching, and belongs to the field of teaching aids. The adjustable matts scriber comprises a transverse plate, a plurality of one-way pulleys are mounted on a bottom plate of the transverse plate, a side plate is mounted at the lower side of one end of the transverse plate, a sliding rail and a bidirectional graduated scale are mounted at the side, away from the transverse plate, of the side plate, and a T-shaped fixing block is fixed in the middle of a sliding groove of the sliding rail. T-shaped sliding blocks are symmetrically arranged at the two sides of the sliding groove of the sliding rail in a sliding manner, drawing pens are installed on the surfaces of the T-shaped fixing blocks and the surfaces of the T-shaped sliding blocks through fixing bases, locking identification bases are installed on the surfaces of the two T-shaped sliding blocks, and the upper ends of the locking identification bases extend to the outer side of the bidirectional graduated scale and correspond to scale marks of the bidirectional graduated scale. The matts of different sizes can be drawn according to needs, the operation process is simple, the requirement for the ability of a user is low, the user can conveniently and rapidly write the matts, and the matts can be regularly drawn.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to an adjustable matts marker for teaching.
