1. a switching operating device, possesses:

  • Tubular fuselage (11);

    Cut off the body of rod (12,12) a pair, their axles are supported on the front end of described fuselage (11), and are formed with cutting portion (12a, 12a) in the tip side of forwards giving prominence to from the front end of described fuselage (11);

    Cut off with slide block (18), it can be contained in described fuselage (11) slidably, and is moved by driving mechanism (13) thus make described cutting portion (12a, 12a) carry out on-off action,The feature of this switching operating device is also possess;

    The a pair clamping body of rod (22,22), they and describedly cut off the front end that the adjacent and axle of the body of rod (12,12) is supported on described fuselage (11) for a pair, and to be formed and described cutting portion (12a, 12a) clamping part side by side (22a, 22a) in the tip side that the front end from described fuselage (11) is outstanding;

    Clamping slide block (23), it is adjacent with described cut-out slide block (18) and can be contained in slidably in described fuselage (11), by moving to equidirectional with described cut-out slide block (18) and make described clamping part (22a, 22a) carry out on-off action;

    Forcing unit (26), described clamping slide block (23) exerts a force to the direction making described clamping part (22a, 22a) carry out closed action by it;

    Relative movement limiting unit (30), the relative movement of its described cut-out slide block (18) of restriction and described clamping slide block (23), forbid that the opening angle (β

    ) of described clamping part (22a, 22a) is less than the opening angle (α

    ) of described cutting portion (12a, 12a)The described closed action of described clamping part (22a, 22a) is carried out in the following manner;

    along with driving mechanism (13) drives to making the closed direction of described cutting portion (12a, 12a) described cut-out slide block (18), advancing in the front of described clamping slide block (23) by described forcing unit (26) force to described fuselage (11), makes described clamping part (22a, 22a) be biased and carry out closed action.
