When sign 24 is switched to " test " by " separation ", stopping pushing inward drawer 100, now unclamp pressing lever 7, the second guide post 62 enters in test draw-in groove 34, can be by spacing for drawer 100 in testing position；
When needing to be completely installed to drawer 100, as shown in Figure 13-17 and Fig. 2-3, pressing pressing lever 7, the second guide post 62 is made to deviate from test draw-in groove 34, continue to push inward drawer, first guide post 22 continues to slide on the first guide edge 31, second guide post 62 slides on the second guide edge 32, during until sign 24 is switched to " connection " by " test ", stop pushing inward drawer 100, now unclamping pressing lever 7, the second guide post 62 enters and connects in draw-in groove 33, and now drawer 100 is spacing at link position.Now the first trigger unit 21 on frizzen 2 contacts with the first control knob 111 being located on the first travel switch 11, and triggers described first control knob 111, make the first travel switch 11 control chopper 300 is in can the state of normal divide-shut brake；The second trigger unit 61 in trigger member 6 contacts with the second control knob 121 being located on the second travel switch 12, and triggers the second control knob 121, make the second travel switch 12 control chopper 300 is in can the state of normal divide-shut brake.
The interlock that the present embodiment the provides course of action when being extracted out from drawer frame 200 by drawer 100 is as follows:
When needing outwards to extract drawer 100 from drawer frame 200 out, first pressing pressing lever 7 (needing before pressing to remove bearing pin 72 and padlock 74), pressing lever 7 promotes trigger member 6 to rotate, the second guide post 62 being arranged in trigger member 6 is made to produce within connecting draw-in groove 33, and make the second trigger unit 62 separate with the second control knob 121 of the second travel switch 12 simultaneously, now the second travel switch 12 controls chopper 300 and is at gate-dividing state；
When using external force outwards to be extracted out from drawer frame 200 by drawer 100, continue to press described pressing lever 7, and the most outwards extract drawer 100 out, first guide post 22 slides on the first guide edge 31, and gradually drive the first trigger unit 21 to separate with the first control knob 111 of the first travel switch 11, first travel switch 11 controls chopper 300 and is in gate-dividing state, and the sign 24 being arranged on frizzen 2 is gradually switched to " separation " by " connection "；Second guide post 62 gradually moves on the second guide edge 32 of motion guide plate 3；
When drawer 100 is completely withdrawn from from drawer frame 200, the first guide post 22 slides with the first guide edge 31 and separates, and the second guide post 62 slides with the second guide edge 32 and separates.
It should be noted that, first travel switch 11 electrically connects with the moment shunt opening coil being located within chopper 300, second travel switch 12 electrically connects with the switching winding being located within chopper 300, when drawer 100 is outwards extracted out, first travel switch 11 can control rapidly chopper 300 separating brake by moment shunt opening coil, it is ensured that safety；When people encounter pressing lever 7 unintentionally, even if causing the second control knob 121 to contact again after separating with the second trigger unit 61 moment, now switching winding will not control chopper 300 separating brake, it is possible to ensures the properly functioning of equipment.
