发明名称 PAIR OF PRESSING JAWS FOR HYDRAULIC OR ELECTRIC PRESSING TOOLS
摘要 The invention relates to a pair of pressing jaws for hydraulic or electric pressing tools for pressing fittings onto pipes or for the press connection of electric cables, two pressing jaws connected to one another in an articulated manner forming a pair of pressing jaws, the pressing jaws being biased into their open position by a tension spring which spans a free space between the two pressing jaws, and in each case one end of the tension spring being accommodated in an accommodating opening which opens out into a narrow peripheral side of the pressing jaw, this narrow peripheral side being directed toward the free space, and, in order to secure the tension spring, a tension-spring end engaging around a pin-like securing part, which securing part is disposed at that end of the accommodating opening which is directed away from the free space. In order to secure the tension spring in a functionally advantageous manner, it is provided that the securing part is formed as an integral crosspiece of the pressing jaw.
