Detailed Description

The invention will be further described with reference to the accompanying drawings in which:

as shown in fig. 1: the ruler comprises a ruler 1, a pen clamping head 2, a drawing pen 3, a sliding groove 4, a sliding block 5, a fixing bolt 6 and a fixing needle 7, wherein the pen clamping head 2 is fixedly arranged at one end of the ruler 1, the drawing pen 3 is detachably connected to the pen clamping head 2, the sliding groove 4 is arranged in the middle of the ruler 1, the sliding block 5 is sleeved on the ruler 1 and can slide, the sliding block 5 and the sliding groove 4 of the ruler 1 are loosened and fixed through the fixing bolt 6, and the fixing needle 7 is fixedly arranged at the lower end of the sliding block 5.

Preferably, the scale 1 is provided with a scale 8.

As an improvement, the upper end of the sliding block 5 is provided with a unidirectional rotating mechanism.

As shown in fig. 2: the unidirectional rotation mechanism comprises a connecting block 9, a fixed gear ring 10, a movable gear ring 11, a sleeve 12, a rectangular outer edge 13, a piston cylinder 14, a piston rod 15, a spring seat 16, a spring 17, a torsion cylinder 18 and a roller shaft bearing 19, wherein the lower end of the connecting block 9 is fixedly connected with the upper end of the sliding block 5, the lower end of the fixed gear ring 10 is fixedly connected with the upper end of the connecting block 9, the lower end of the torsion cylinder 18 is rotatably connected with the fixed gear ring 10 through the roller shaft bearing 19, the movable gear ring 11 is in contact with the fixed gear ring 10, the upper end of the movable gear ring 11 is fixedly connected with the lower end of the sleeve 12, the side edge of the sleeve 12 is the rectangular outer edge 13, the middle part of the sleeve 12 is the piston cylinder 14, the inner part of the torsion cylinder 18 is fixedly connected with the rectangular outer edge 13 of the sleeve 12, the piston rod 15 is movably connected with the piston cylinder 14, the spring seat 16 is fixedly connected with the upper end of the piston rod 15, the spring seat 16 is detachably connected with the upper end of the torsion tube 18, and the spring 17 is located between the sleeve 12 and the spring seat 16.
