FIELD: metallurgy.
SUBSTANCE: invention refers to processing metal by pressing and can be implemented in benders for fixing items with holder of big weight in upper and lower positions. The mechanism of control of holder position in benders consists of an immobile element coupled with its axis with the case of the bender. A guiding channel with recesses on end sections is installed into the immobile element. There is also a mobile element connected to the holder and a control lever made as an active arm, axis of which is positioned in the mobile element and rigidly tied with it in the point of connection to axis of a passive arm with a bearing. Also the bearing is located in the said guiding channel and can travel in it, occupying recesses on end sections to fix the holder in the upper and lower positions.
EFFECT: simplified design of device.
