Lever 47 is rotated, and when the first shifting part 481 reaches precalculated position, the first induction pieces 483 can be touched, by first induction pieces
483 send signal, drive motor 20 is shut down, and power transfer unit 30 will also decommission, and thereby, can avoid causing valve
The possibility that door, air door or YE are damaged；When drive motor 20 does antiport again, the position of the rod member 42 can be returned
To the normal condition of Fig. 7, and elastic component 45 also returns to normal uncompressed state therewith.
Then it is that the direction as shown in the arrow 54 of Fig. 9 rotates as in the case where valve or other analogs are closed, if
Valve cannot be closed for some reason, and when the output torque of power transfer unit 30 reaches preset value, rod member 42 can be according to side shown in arrow 55
To displacement, the locating part 46 will promote the 3rd plate 44 according to direction displacement shown in arrow 55, because the second plate 43 is by shrouding
13 restrain, and will not move, so elastic component 45 is in compressive state, the first rodent part 422 can drive drive link 47 according to the institute of arrow 56
Show that direction rotates, when the second shifting part 482 touches the second induction pieces 484, drive motor 20 will be made to shut down；Similarly,
When drive motor 20 does antiport again, the rod member 42 and elastic component 45 will be returned to the normal condition of Fig. 7.
In addition, being second embodiment of the present utility model shown in Figure 11, Figure 12, it is main with above-mentioned the first embodiment
Difference is：The elastic component 45 is made up of the disk spring of predetermined number.
Below the utility model is described in detail, but the above, preferable implementation only of the present utility model
Example, can not limit the scope of the utility model implementation.I.e. all impartial changes made according to present utility model application scope
Change and modify etc., all should still belong to patent covering scope of the present utility model.
