As Fig. 1, Fig. 2, Fig. 7 and shown in Figure 8, but this second in command organizes 8 lock group 82 and this first in command and organizes the operation that 7 lock group 72 control lock bodies are done locking or release, and it is inboard at lock body as long as drive seat 26 is stirred in the pushing part 494 that this second in command 81 of rotation drives these driving tubes 49, can open door leaf, but not change original blocking or the released state of setting of lock body.

As Fig. 1, Fig. 2, Fig. 7 and shown in Figure 8, when operating this second in command with correct key (not shown) when organizing 8 lock group 82 and being blocking, make this core 821 of rotation spend original position from the angular displacement about 360 that original position moves a predetermined direction, this moment should lock group 82 driving member 822, can promote this drivening piece 48, and then make this drivening piece 48 can directly drive this axostylus axostyle 47 rotations, because two helicla flutes 453 of this tumbler 45 align mutually with the through hole 475 of this axostylus axostyle 47, and the relation that connected by a pin 455, so when axostylus axostyle 47 rotates, after this tumbler 45 can produce axial displacement one distance with respect to this axostylus axostyle 47, up to this tumbler 45 axial displacement again, this tumbler 45 promptly begins to rotate, so this connecting rod 356 promptly can rotate, and the tumbler 35 that drives this first drive mechanism 3 produces an axial displacement, the retaining ring groove 359 that so is positioned on this tumbler 35 can be done axial displacement by this clutch part 34 of drive, the engaging piece 343 that makes the engaging piece 343 of this clutch part 34 can move to this clutch part 34 from the second place (as shown in Figure 8) of the engaging piece 313 that meshes this collar 31 does not mesh the primary importance (as shown in Figure 7) of the engaging piece 313 of this collar 31, the idle running that this tube element 39 of meeting interlock produces a predetermined angular when therefore rotating this first in command 71, and can't drive impeller 32 starts, to form the state of outside locking.

As Fig. 1, Fig. 2, Fig. 7 and shown in Figure 8, when when organizing 8 lock group 82 from the second in command and remove lock bodies outside blocking, must operate this lock group 82 with correct key (not shown) in the lock body inboard, make this core 821 of rotation spend original position from the angular displacement about 360 that original position moves a predetermined direction, this moment should lock group 82 driving member 822 can be with above-mentioned reverse operation, the driving member 822 of this lock group 82, can promote this drivening piece 48 and directly drive this axostylus axostyle 47 rotations, because two helicla flutes 453 of this tumbler 45 align mutually with the through hole 475 of this axostylus axostyle 47, and the relation that connected by a pin 455, so when this axostylus axostyle 47 rotates, after this tumbler 45 can produce axial displacement one distance with respect to this axostylus axostyle 47, this tumbler 45 is again during axial displacement, this tumbler 45 promptly begins to rotate, so connecting rod 356 promptly can rotate, and the tumbler 35 that drives this first drive mechanism 3 produces an axial displacement, and then this tumbler 35 can promote these clutch part 34 axial displacements, the primary importance (as shown in Figure 7) that makes the engaging piece 343 of this clutch part 34 can never mesh the engaging piece 313 of this collar 31 moves to the second place (as shown in Figure 8) of engaging piece 313 of engaging piece 343 these collars 31 of engagement of this clutch part 34, when understanding these tube element 39 these collars 31 of interlock of interlock when therefore rotating this first in command 71, mesh the engaging piece 343 of these clutch parts 34 because of the engaging piece 313 of this collar 31, and the groove 342 of this clutch part 34 is set on the protuberance 323 of this impeller 32, and then the pushing part 322 that drives this impeller 32 drives the support 262 of this drive seat 26, make this drive seat 26 do to move and the internal drive element of pulling latch mechanism 9 is removed and received plunger latch head 91, can open door leaf.

If the blocking desire is opened the door from outside lock body, must organize 7 lock group 72 with the correct key (not shown) operation first in command, make this core 721 of rotation spend original position from the angular displacement about 360 that original position moves a predetermined direction, this moment should lock group 72 driving member 722 can promote this drivening piece 38 idle running one angle, can be positioned at the centre position of the arcuation groove 374 of this axostylus axostyle 37 because of the clicking section 382 of this drivening piece 38 of normal condition, and then the clicking section 382 that makes this drivening piece 38 promotes the pushed part 376 of this axostylus axostyle 37, make this axostylus axostyle 37 produce rotation, because two helicla flutes 353 of this tumbler 35 align mutually with the through hole 375 of this axostylus axostyle 37, and the relation that connected by a pin 355, so when this axostylus axostyle 37 rotates, this tumbler 35 can produce axial displacement one distance with respect to this axostylus axostyle 37, and then promote this clutch part 34 and produce axial displacements, the primary importance (as shown in Figure 7) that makes the engaging piece 343 of this clutch part 34 can never mesh the engaging piece 313 of this collar 31 moves to the second place (as shown in Figure 8) of engaging piece 313 of engaging piece 343 these collars 31 of engagement of this clutch part 34, when understanding these tube element 39 interlock collars 31 of interlock when therefore rotating this first in command 71, mesh the engaging piece 343 of these clutch parts 34 because of the engaging piece 313 of this collar 31, and the groove 342 of this clutch part 34 is set in the protuberance 323 of this impeller 32, and then the pushing part 322 that drives this impeller 32 drives the support 262 of this drive seat 26, make drive seat 26 do to move and the internal drive element of pulling latch mechanism 9 is removed and received plunger latch head 91, can open door leaf.

Organize 72 lockings if will organize 7 lock, also getting final product, will repeat no more at this with above-mentioned rightabout operation with this first in command.

Above-mentioned first specific embodiment is organized 8 functions that have lock group 72 and lock group 82 respectively for this first in command organizes 7 with this second in command, it is also variable more as Fig. 9 and second specific embodiment shown in Figure 10, only this first in command organizes 7 functions with lock group 72, and this second in command organizes 8 ' lock group not, should organize the second in command 8 ' the second in command 81 ' and change to no lock group installing hole this moment, and the lock group 82 of first specific embodiment removed, and this second drive mechanism 4 relatively also must remove this drivening piece 48, this axostylus axostyle 47, this spring 46, this tumbler 45, this pin 455, this sleeve pipe 43, this connecting rod 356 and this spring 360 etc. so promptly form the function that the column type lock only has one-sided lock group.

The foregoing description and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
