Annulus outer wall is close to and is hemispherical structure, and contact bar is located at the end outside pedestal across having a holddown spring, holddown spring one
End is fixed with pedestal, and the holddown spring other end is fixed with contact bar, and annulus and contact bar are all made of conductive material and are made, and contact
Bar is used to form the moved end of controllable single-pole double-throw switch (SPDT), and holddown spring is in confined state.Due in rotation process, moved end
Not necessarily, therefore the moved end for forming fixed controllable single-pole double-throw switch (SPDT) is very troublesome for the position of contact 84, so setting circle
Ring, contact bar and pedestal so that the electrotransformation of 84 band of moved end contact in connection rotation to transversely movable contact bar
On, a conducting wire is only arranged in contact bar, and conducting wire is located at the section long enough in switching chamber 811 just, can form fixed controllable list
The moved end of double-pole double throw switch.Holddown spring enables contact bar to be moved under the rotation of annulus, also can guarantee contact bar and circle
Ring is close to, and the end be close to annulus of contact bar is ball shape structure, can ensure when annulus is connected to each other feeler lever rotation annulus and
Contacting bar, friction is small, avoids contact with bar well damage.
Due to when replacing, needing new first relay or the second relay connecting with high voltage power supply, therefore easily go out

The threaded hole of connection is located between lid 12 and triggering chamber 14, and shell ontology 11 is recessed close to the face of lid 12 and compresses hole 16,
The diameter for compressing hole 16 is more than the diameter of threaded hole, offers on lid 12 and the perforation that compresses hole 16 and be aligned；Each blocking group
Part 5 includes：Stopper 51, stopper 51 is arc-shaped to be bent to screw rod 46, and stopper 51 connects the extension of oriented screw rod 46
Moving cylinder 52, moving cylinder 52 is slidingly arranged on a guide rod 53, and end of the guide rod 53 far from stopper 51 is fixed on
On the round end of screw rod 46,46 top surface position of screw rod is higher than 51 top surface position of stopper, and moving cylinder 52 is fixed with one
Press block 54, press block 54 are median surface and median surface and 46 centerline parallel of screw rod and be press block close to the face of screw rod 46
54 faces far from screw rod 46 are contact surface, press block 54 be it is trapezoidal, the big end of press block 54 close to stopper 51, press block 54
Small end be located at compresses in hole 16, and the contact surface of 54 big end of press block to 46 center line of screw rod distance be more than compress hole 16 partly
The distance of diameter, contact surface to 46 center line of screw rod of 54 small end of press block is less than the radius for compressing hole 16, and guide rod 53, which passes through, to be had
One compresses spring 55, and the one end and screw rod 46 for compressing spring 55 are fixed, and the other end and moving cylinder 52 for compressing spring 55 are fixed；When
When the big end of trigger head 47 is contacted with pulley 45, the vertical range of stopper 51 face far from screw rod 46 to perforated base line is more than
The radius of perforation；When the small end of trigger head 47 and pulley 45 contact, face of the stopper 51 far from screw rod 46 to perforated base line
Vertical range be less than perforation radius.Due to when the big end of trigger head 47 and pulley 45 contact stopper 51 far from screw rod 46
Face to perforated base line vertical range be more than perforation radius, it is therefore desirable to lid 12 is detached with shell ontology 11, just must
It must rotary screw 46 so that the small end of trigger head 47 is contacted with pulley 45, while face of the stopper 51 far from screw rod 46 is to perforating
The vertical range of center line is less than the radius of perforation, in this way, preventing from maloperation so that only in the wiring of switching circuit board 2
Lid 12 can be opened after column power-off.And this connection type, the release of disposable power-off and lid 12 is realized, behaviour is facilitated
Make so that the operation is more convenient.
Finally illustrate, the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although with reference to compared with
Good embodiment describes the invention in detail, it will be understood by those of ordinary skill in the art that, it can be to the skill of the present invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of technical solution of the present invention, should all be covered at this
In the right of invention.
