IB cut through the rocker 5, reinforced by the middle part of the pivot on a nail or stud and made of plywood or metal.

At the ends of the yoke, front and rear, holes are drilled and metal rings are drawn in them, the back ring is attached; the zinen spiral spring 7 has ears, the lower end is attached to the table so that the rocker arm opposite end lifts; which is fixed at the lower end to the eyelet in the middle of the second crossbar 3 of the frame, as a result of which the frame remains raised front. To both the rails of frame 2, 2 from the bottom between the first 7 and second 3 crossbars, the ends are attached with a long wire and passed through two holes made in the table under them.
