It is connected on motor 4, so that motor 4 can drive the first driving cam 9 to be rotated；Second driving cam 10, position
In the lower section of the first driving cam 9, and the first driving cam 9 has the first circumferentially arranged cam surface, the second driving cam 10
With the second circumferentially arranged cam surface；First cam surface and the second cam surface are mutually chimeric, so that 9 turns of the first driving cam
The second activity downwards of driving cam 10 can be promoted when dynamic and the second driving cam of synchronous drive 10 is driven therewith；First non-return piece
11；Second non-return piece 12, positioned at the lower section of the first non-return piece 11 and it is set around the periphery of the second driving cam 10, the second non-return piece 12
Can synchronous axial system and can synchronous movement along the vertical direction with the second driving cam 10；Second non-return piece 12 is configured with recess 12A, the
One non-return piece 11 is corresponding to be configured with convex portion, and the second non-return piece 12 can drive recess to be separated with convex portion when movable downwards；Reset bullet
Property part 13, apical grafting is between the second driving cam 10 and reducing gear 6.
Output shaft 3 is to connecting valve structure (such as butterfly valve), to adjust the state of valve mechanism.Reducing gear 6 can be more
Level planet gear reducing mechanism, it is the skill that industry is known, therefore is repeated no more.Return springs 13 can be spring.Implement first
In example, the first non-return piece 11 is configured to support on the motor support frame 8 of motor 4.Second non-return piece 12 is circumferentially matched somebody with somebody
Put and be uniformly configured with multiple recess 12A.In the present embodiment, motor support frame 8 is in cylinder with what is extended along the vertical direction
The cavity volume of shape, motor 4 are supported on motor support frame 8, and the first driving cam 9, the second driving cam 10 and second are non-return
Part 12 is rotatably arranged in the cavity volume of motor support frame 8.The side wall of the cavity volume of motor support frame 8 can form roll structure can
The first driving cam 9 and the second non-return piece 12 is set to be rotated more glibly.
In the first embodiment, there is the first depressed area 10A and the second depressed area 10B, the first cam on the second cam surface
The first projection portion 9A and the second projection portion 9B are correspondingly configured with face；First projection portion 9A is movably embedded in the first depressed area
In 10A, by the first projection portion 9A the second driving cam 10 can be promoted to be located at the first depressed area when the first driving cam 9 is driven
10A cam surface, so that the second driving cam 10 can be movable downwards；Second projection portion 9B is movably embedded in the second depressed area
In 10B, by the second projection portion 9B the second driving cam 10 can be promoted to be located at the second depressed area when the first driving cam 9 is driven
