Rod adjustment handwheel.

Said knife transfer frame includes a marking head and a front and rear swinging rod for fixing the marking head, and the front and rear swinging rod is driven to swing forward and backward by an operating rod connected to it.

The marking head and the front and rear swing rods are threadedly matched so that the marking head moves up and down on the front and rear swing rods, and a limit block is arranged on the lower part of the front and rear swing rods where the marking head is located. It is fixed on the lower part of the scribing head through thread fit, so that the scribing head can move up and down between the front and rear swing rods and the limit block.

Threads are provided on the screw rod, and the distance between two consecutive threads is 10 mm.

The beneficial effects of the utility model are: by choosing to use the gantry or thimble, the utility model can shake the cylindrical metal sample under the action of the handwheel chuck so as to meet the requirement of drawing an arc on the metal sample, At the same time, through the fixing of the gantry frame, the metal sample can be fixed in the sample fixing groove to draw a straight line perpendicular to the axial direction on the metal sample, and the requirement of drawing parallel lines can be achieved by rotating the screw rod. As a result, the knife holder can smoothly draw a circle of arcs on the metal sample, and at the same time, the gantry can be used instead of the thimble to draw a straight line on the metal sample. It is easy to use, simple in structure, and has a wide range of applications. The advantage is that it can meet the requirement of drawing an arc when measuring the gauge distance, which greatly improves the utilization rate and effect of the product.
