Abstract: FIELD: unpacking equipment.  
     SUBSTANCE: device includes a motor and connected grippers. The output shaft of the engine is rigidly connected to the rotation sleeve, made in the form of a cup with an open internal cavity facing away from the engine. The motor shaft and the rotation sleeve are installed coaxially relative to each other. The device contains a panel with U-shaped horizontal section, the middle part of which is made with a through hole and placed vertically, while the inner cavity of the panel is facing the rotation sleeve. At the ends of the sides of the panel, the panel sleeve is rigidly fixed coaxially with the rotation sleeve. On the outer surface of the rotation sleeve, a control sleeve is installed coaxially with it, made with the possibility of longitudinal movement along the outer surface of the rotation sleeve. On the outer surface of the control bushing, a bearing is installed coaxially with it, located between the control bushing and the panel bushing that presses the bearing to the control bushing. In the inner cavity of the rotation sleeve there is a fixing axis, on which the ends of L-shaped grippers are fixed, designed to hold the fixing clip of the product. The grippers are fixed on the mounting axis with the possibility of rotation around it. The longitudinal axis of the mounting axis is perpendicular to the axis of the motor shaft. The length of the mounting axis is greater than the outer diameter of the rotation sleeve. The ends of the mounting axis extending beyond the rotation sleeve are located in the holes made in the control sleeve, while the mounting axis is installed with the possibility of free movement along the axis of the motor shaft along through grooves made on the side surface of the rotation sleeve opposite each other and simultaneously parallel to the axis of rotation of the motor shaft. The dimensions of the inner diameter of the rotation sleeve and the length of the grooves are selected given the condition of ensuring complete closure of the ends of the L-shaped grippers at the final position of the mounting axis closest to the motor occupied by the mounting axis under external pressure on the panel. The initial position of the mounting axis, the most distant from the engine, provides a free open position of the ends of the L-shaped grippers for placing the product fixing clip between them.
