On, and the end cap 10 to play a protective role is equipped with above the recess portion 13.
The operation principle of the present invention is that：
When control system sends out conjunction split instruction, motor is established by cable beginning rotation, it is assumed that and driving gear 1 is rotated by combined floodgate direction,
Dropout gear 3 is driven to rotate, dropout gear 3 installs two sets of bi-directional movable tooth form pawls, splitting or integrating lock in the anodontia position calculated
Process is respectively with a set of, and each activity tooth form pawl is identical as dropout gears tooth pitch at a distance from adjacent limit activity between cog.
As shown in figures 1 and 3, when combined floodgate, driving gear 1 rotates clockwise, since the first activity tooth form pawl 6 cannot be to
Side rotation far from spring 7, driving gear 1 is engaged the first activity tooth form pawl 6 on dropout gear 3 first, and passes through institute
Stating the first activity tooth form pawl 6 makes dropout gear 3 rotate a tooth position, and the fixation tooth on dropout gear 3 and driving gear 1 are reliable
Occlusion, dropout gear 3 normally rotate, and by slave drive axis 4, driven output gear 5 are driven to rotate, output connection the following group tune
Whole gear output switchs required rotation angle, and the first limit movable teeth 9, which is depressed, is not involved in transmission.As shown in figure 4, working as machine
When structure is closed a floodgate on earth, since the second activity tooth form pawl 11 can be rotated to the side equipped with spring 7, the second activity tooth form pawl
11, which are depressed, is not involved in engaged gears, the last one tooth engaged of dropout gear 3 is the second limit movable teeth 12, and dropout gear 3 revolves
