The operation handle 8 outside 1 side plate of box body is connect, the first articulated shaft 10 passes through jack box box side and protrudes into grafting box body 1
The end in portion be connected with can be rotated with operation handle 8 around the first articulated shaft 10 with push in jack box molded-case switch point,
That closes a floodgate pulls out plate 11；The position that 1 side plate interior sides of grafting box body are located at 10 top of the first articulated shaft is hinged by the second articulated shaft 7
There is jam plate 3, the end that jam plate 3 and grafting box door lock are adapted is provided with the limited block 12 to raise upward, 3 other end of jam plate middle part
It is located at jack box side plate with horizontal guide slot 4, on the first articulated shaft 10 and pulls out and is also hinged on position and jam plate 3 between plate 11
In parallel, the pulling plate 6 that can be rotated with operation handle 8 around the first articulated shaft 10, pulling plate 6 are located at the end of 4 lower section of guide groove
The at L-shaped pulling plate of the structure that raises upward, the end that pulling plate 6 raises upward is provided with horizontal extension, can extend into guide groove 4 with guiding
The pin shaft 5 that the cooperation of slot 4 pushes jam plate 3 to rotate around the second articulated shaft 7；Making handle drives shift plate, pulling plate simultaneously around the first articulated shaft
Rotation pulls out plate by limiting slot and pushes molded-case switch divide-shut brake inside jack box, and stable operation is reliable, and pulling plate is protruded by pin shaft
It pushes jam plate to rotate around the second articulated shaft in guide groove, drives limited block to be upturned and lock grafting box door lock, so that plastic housing is opened
