Further, described bayonet arrangement is: the lower surface of output sleeve is symmetrical arranged a pair of output shaft claw, the upper surface of power shaft is symmetrical arranged a pair of arc-shaped slot, and described output shaft claw can embed in the arc-shaped slot, and freely rotates certain angle along power shaft, output shaft axle center.
Further, the angle that can freely rotate in arc-shaped slot of described output shaft claw is 90 °.
Further, described pull bar comprises rod head and bar body, and an end and the connecting lever of described rod head are hinged, and the other end is threaded with bar body.
Further, the other end of described bar body arranges the adjusting keyway.
The utility model has the advantage of: earthed switch is when moving from open position to closing position, power shaft drives output shaft, output sleeve rotates, so that moving to drag link sleeve, pull bar shrinks the compression spring energy-storage, after output shaft turns over certain angle, spring releases energy and promotes fast the output shaft rotation, reaches the purpose of rapid closing.Clapper-type earthed switch contact, fingertip divide-shut brake difficult problem when having solved the motor drive mechanism Rotating with Uniform.Simple in structure, easy with the motor-operating mechanism interface.Spring force can be realized regulating by the rotating rod body according to demand.

Embodiment
Shown in Fig. 1,3, comprise shell 1, output shaft 3, power shaft 2, lower flange 4, upper flange 5, output sleeve 6, lock-screw 7, drag link sleeve 8, pull bar 9, connecting lever 10, Compress Spring 11.
Concrete: the lower surface of shell 1 is stretched out in the lower end of power shaft 2, is connected with axle sleeve a by lower flange 4 between the lower surface of output shaft 2 and shell 1.The lower end axis body of output shaft 3 is partially submerged into the axis hole at center, power shaft 2 upper end, and between arranges axle sleeve c, and the upper surface of shell 1 is stretched out in the upper end of output shaft 3, is connected with axle sleeve b by upper flange 5 between output shaft 3 and shell 1 upper surface.
Be connected with output sleeve 6 by key outside the output shaft 3, and be locked by lock-screw 7.The lower surface of output sleeve 6 is connected by bayonet arrangement with power shaft 2 upper ends.
The bayonet socket concrete structure is:
Shown in Fig. 2,4,5,6,7, the lower surface of output sleeve 6 is symmetrical arranged a pair of output shaft claw 61, and the angle that output shaft claw 61 both sides and its axle center form is 60 °, forms draw-in groove 62 between the adjacent output shaft claw 61; The upper surface of power shaft 2 is symmetrically arranged with a pair of arc-shaped slot 21, forms projection 22 between the adjacent arc-shaped slot 21, and the angle that the both sides of arc-shaped slot 21 and its axle center form is 150 °.Output shaft claw 61 embeds in the arc-shaped slot, and freely rotates certain angle along power shaft, output shaft axle center, and this angle is 90 °.
One drag link sleeve 8 also is installed in the shell 1, the pull bar 9 that is slidingly connected in the drag link sleeve 8, an end of pull bar 9 is hinged with the connecting lever 10 that is fixed on the output sleeve 6, and Compress Spring 11 is installed on the pull bar 9.In the present embodiment, pull bar 9 comprises rod head and bar body, and an end and the connecting lever of rod head are hinged, and the other end is threaded with bar body, and at the other end of bar body the adjusting keyway is set.
During use, as shown in Figure 8, the shell 1 of fast actuation mechanism is installed in the top of electric operating mechanism cabinet 12 by support 13, and power shaft 2 is connected with the output shaft of electric operating mechanism, and output shaft 3 is connected with vertical tube joint 14.
