Rise the deformability at matrix two ends so that the two ends of matrix easily deform upon and easily and in Access Division snap-fit engagement, and matrix
Between part be solid section, the when of turning handle, force part the most in the base between, such matrix is hardly damaged；Breach
Arrange and facilitate Access Division to separate with matrix, promote Access Division to move to both along length thereof direction by pressing breach and divide
From, extension is plugged on Access Division the length ensureing that handle is enough, facilitates operator to operate, and blocks not using when
The portion of will extend over pulls down.
Further, in described housing, it is additionally provided with static contact and moving contact, by passing between described moving contact and handle
Motivation structure connects, described drive mechanism include being rotationally connected in the middle part of one end and the retainer of housing hinge, one end and retainer and
What the other end and handle were rotationally connected lever, described moving contact is fixed on the other end of retainer, the most fixing in described housing
One back-moving spring, described back-moving spring abuts with retainer.
Handle rotates and drives lever rotation, and retainer force is driven retainer to rotate around the pin joint with housing by lever,
Back-moving spring is compressed, and moving contact rotates along with retainer and finally contacts with static contact and realizes circuit ON；Otherwise, handle is anti-
To rotation, back-moving spring is replied thus is driven retainer to rotate backward, finally makes static contact separate with moving contact.
Further, arranging spring base in described housing, described back-moving spring is fixed in spring base, in described spring base
Also fixing a lead, described back-moving spring is socketed on lead.
So can reduce back-moving spring radial deflection, extend the service life of back-moving spring.
Further, described retainer offering elongated hole, described lever one end is provided with the rotating shaft being positioned at elongated hole, institute
State and be socketed with the two ends of torsion spring and torsion spring in rotating shaft and abut with retainer.
So, after turning handle realizes moving contact and static contact Guan Bi, lever is pressed down, and rotating shaft is downward along elongated hole
Moving makes torsion spring twist, so the reliability of the Guan Bi between guarantee moving contact and static contact.
Further, described housing is fixed with observation window.The setting of observation window is easy to observe inner case.
In sum, this utility model has the advantages that this utility model simple in construction, easy to operate, can be real
The local replacing of existing handle.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
This specific embodiment is only that it is not to restriction of the present utility model, ability to explanation of the present utility model
The present embodiment can be made after reading this specification by field technique personnel as required does not has the amendment of creative contribution, but
As long as all being protected by Patent Law in right of the present utility model.
A kind of disconnecting switch, as it is shown in figure 1, include the housing 1 being fixed with observation window 11.Housing 1 both sides are fixed with first
Binding post 14 and the second binding post 15, the first binding post 14 is fixed with the first contact chip 16, and the first contact chip 16 is substantially in L
Shape, one end of the first contact chip 16 is fixed with static contact 2.The second contact chip 17, the second contact it is fixed with on second binding post 15
Sheet 17 is substantially L-shaped, and the first contact chip 16 and the second contact chip 17 are copper sheet.Fix first in housing 1 and fix axle 12 and
Two fix axle 13, and handle 3 is socketed in first and fixes on axle 12 and can fix axle 12 around first and rotate, concrete, such as Fig. 2-3, hands
Handle 3 includes matrix 31, be socketed on matrix 31 and with the Access Division 32 of matrix 31 clamping, the extension that is plugged on Access Division 32
33, matrix 31 center is offered through hole and is coordinated with fixing axle and realize matrix 31 and fix being rotationally connected of axle 12 with first, matrix 31 to
Extending outward housing 1, groove 311 is offered at matrix 31 two ends, and the both side ends of Access Division 32 all offers a breach 322, two
Breach 322, to overlap after the central rotation 180 degree of Access Division 32, offers draw-in groove 323, draw-in groove 323 along Access Division 32 length direction
Width less than matrix 31 width 0.05-0.1mm；Offer slot 321 on Access Division 32, extension 33 is fixed projection 331
Realization coordinates with slot 321, and increasing slot grinding 332 is also offered in the side of extension 33, for increasing the contact area with finger, square
Just will extend over portion 33 to take out.Such as Fig. 1, second fixes axle 13 is positioned close to second contact chip 17 one end, one end of retainer 4 with
Second fixes axle 13 is rotationally connected, and this end is fixed by soft link 5 and the second contact chip 17, and soft link 5 refers to soft
Plain conductor, such as copper cash etc., the other end of retainer 4 is fixed with moving contact 6, and moving contact 6 is oppositely arranged with static contact 2.Thick stick
Bar 7 one end is hinged on the handle 3, rotates with the rotation of handle 3, and lever 7 other end is fixed with rotating shaft 71, and retainer 4 is opened
If elongated hole 41, elongated hole 41 extends along retainer 4 short transverse, and torsion spring 72 is socketed in rotating shaft 71 and the two ends of torsion spring 72 abut biography
Dynamic seat 4.Being further fixed on spring base 8 in shell, fix a lead 81 in spring base 8, back-moving spring 82 is socketed in lead 81
Above and with spring base 8 fixing and be connected, back-moving spring 82 abuts with retainer 4.
Handle 3 rotates and drives lever 7 to rotate, and retainer 4 force is driven retainer 4 around the pin joint with housing 1 by lever 7
Rotating, back-moving spring 82 is compressed, and moving contact 6 is along with retainer 4 rotates and finally closes with static contact 2, real at turning handle 3
After existing moving contact 6 and static contact 2 Guan Bi, lever 7 is pressed down, and rotating shaft 71 moves down so that torsion spring 72 occurs along elongated hole 41
Reverse, so the reliability of the Guan Bi between guarantee moving contact 6 and static contact 2；Otherwise, handle 3 rotates backward, and torsion spring 72 is first multiple
Position, back-moving spring 82 is replied thus is driven retainer 4 to rotate backward afterwards, finally makes static contact 2 and moving contact 6 separate.
