The utility model provides a marking device for a part cut-off line, which comprises a backup plate 1, a graduated scale 2 vertically inserted in the backup plate 1 and capable of sliding up and down in the vertical direction, a lock tongue 6 clamped at the top of the backup plate 1 and used for locking the graduated scale 2 at a required height position, and an observation mirror 3 buckled and fixed on the side edge of the backup plate 1.

The backing plate 1 is a main body part of the scribing device, the backing plate 1 is a T-shaped plate, the width of the backing plate 1 is larger than that of the longitudinal through hole 4 on the rib plate 7, and when the scribing device is in actual use, the width of the backing plate 1 is designed to be more than 100mm so as to meet the requirement. The middle of the backup plate 1 is vertically provided with a first groove for inserting the graduated scale 2, and the top of the backup plate 1 is provided with a second groove for installing the lock tongue 6. In this embodiment, the cross section of the first groove is isosceles trapezoid, and the longitudinal section of the second groove is isosceles trapezoid.

The graduated scale 2 is provided with scale marks, and the side edge of the graduated scale 2 is provided with a clamping groove 5 for inserting the lock tongue 6. When scale 2 is vertical to be inserted in first recess, go up, move scale 2 down, adjustable scale 2 is at the depth of insertion of first recess, when adjusting suitable position (the scale that shows should equal with the height of flat-bulb steel on scale 2 this moment), slides spring bolt 6 in the second recess right, makes its tip insert in corresponding draw-in groove 5 of scale 2 left side limit to with scale 2 locking at current high position.
