The folded net (3) is accommodated inside the inner part (2) of the hollow handle, positioned beside two spreading rods (4,4') which are pivotally joined to two parallel bolts (21). When a string (14), guided through the outer handle part (1,5,6) and around a return pulley (13,16) between inner (2) and outer part (5) is pulled, the inner part (2) is pushed forward by a spring mechanism (28,29,30), the net (3) is unfolded by the motion of two spreading angles (31) acting on the spreading rods (4,4'). It is kept in an opened position by a system of two or more strings (38,41) and two springs (33,33'), positioned alongside the net (3).
