(058) it is rotatably assorted in and with it, the convex block (121) and the convex block (056) activity cooperate.
The course of work of the invention is as follows: state as shown in Figure 3, moves up stir head 072, the spacing head of reversing plate 07
071 is detached from limiting slot 051, and at this time according to dress door direction, rotating handles 03 to required side are slightly larger than 90 degree, unclamps stir head
072, reversing plate 07 is fallen into spacing breach 057 by 08 pulling force effect of reset spring, spacing head 071, unclamps again handle 03, multiple
Position plectrum 06 is by 08 pulling force effect of reset spring so that convex block 056 resists spacing head 071, i.e., handle only by when spring force always
In horizontality, the quick commutation action of handle is completed, in commutation process, with 061 phase of spring hanger for resetting plectrum 06
The spring carrier arm of reset spring 08 even can be unhinderedly from the one of the middle position mobile spring hanger 061 of spring hanger 061
End position, as shown in Fig. 2, Fig. 4；Such as the visual angle of exemplary diagram 4, convex block 056 resists convex block 121 at this time, is rotated down handle counterclockwise
Hand 03, namely the pulling axis 1 being solid-located with handle rotate counterclockwise, and pulling axis 1 pushes pulling axis 2 12 to rotate counterclockwise,
Realize each lock point unlocking action to lock body.
As exemplary diagram 4 visual angle under, rotate in insure knob 09, so that interior insurance plectrum 10 rotates clockwise, drive hole
102 drive pin 131 to move, i.e. solution safeguard 11 moves upwards, and convex block 113 approaches pin 132, and interior insurance knob 09 is by lock body
Interior torsional spring active force can stir solution safeguard 11 and approach and be ultimately at the final position insured；It is rotated down counterclockwise at this time
Handle 03 resets the pin 131 on plectrum 06 and resists and solution safeguard 11 is pushed to move downward, when handle 03 rotates by a certain angle
Afterwards, interior insurance knob 09 can be accelerated to rotate counterclockwise by torsional spring active force in lock body, namely the solution acceleration of safeguard 11 is pulled to move down
To unlocked original state is insured, continues to rotate counterclockwise handle 03 namely pulling axis 1 continues to press on 2 12 inverse time of pulling axis
Needle rotation, completes each lock point unlocking action to lock body.
If outer handle is unlocked, pulling axis 2 12 can be rotated with outer handle, equally under the visual angle of exemplary diagram 4, pulling axis two
12 be to rotate counterclockwise, and the convex block 056 and convex block 121 being in contact originally at this time then separate, i.e., the rotation of pulling axis 2 12 at this time is not
It causes Internal handle to link, namely realizes the performance of inside and outside handle self contained function.
The above, only specific embodiments of the present invention, not make limitation in any form to the present invention, for
For those skilled in the art, under the premise of not departing from technical solution of the present invention, make it is several it is simple modification,
Replacement, modification, each fall within protection scope of the present invention.
