Specific embodiment
As shown in attached drawing 1-7, the utility model includes support base 7, the controllable over run clutch being fixedly mounted on support base 7
Device 8 and control device；There is through-hole on support base side plate, the input terminal 12 of controllable overrunning clutch 8 is fixedly mounted in through-hole
With the transmission axis connection of motor 1；The output end 13 of controllable overrunning clutch 8 is connect with transmission device；Input terminal 12 and output end
Intermediate ring 14 is arranged in 13 suits between input terminal 12 and output end 13, interval setting pusher dog 16, intermediate ring inside intermediate ring 14
1 or more claw 17 is uniformly arranged on 14 outer walls, input terminal 12 is sleeved on pusher dog 16, and the intermediate ring 14 is sleeved on output
On end 13, roller 15 is installed between pusher dog 16；It is connected between the output end 13 and the intermediate ring 14 by preloading spring,
Pretightning force can make the two direction of rotation on the contrary, roller 15 is allocated to the left side of 13 outer profile planar section of output end by pusher dog 16；Institute
Stating claw 17 is 1-8, and the present embodiment is 2；The control device includes 4 He of electromagnet being fixedly mounted on support base 7
It is mounted on the pawl 2 on support base 7 by pin shaft 6, pawl 2 can be rotated around pin shaft 6；The iron core of electromagnet 4 and 2 left end of pawl connect
It connects, reset spring 3 is set on the iron core of electromagnet 4, the reset spring 3 is between electromagnet 4 and pawl 2；Pawl 2 is right
End and 17 holding of claw or disengaging.
Transmission device described in the utility model includes coupling spindle 5, crank 9, connecting rod 10 and sliding block 11, the coupling spindle 5 one
End is connect with 8 output end of controllable overrunning clutch, and 5 other end of coupling spindle is connect with crank 9,9 other end of crank and connecting rod
10 connections, are revolute pair between crank 9 and connecting rod 10, and connecting rod 10 is connect with sliding block 11, are rotation between connecting rod 10 and sliding block 11
It is prismatic pair between the bottom plate or ground of pair, sliding block 11 and support base 7.
When the utility model original state, input terminal 12 is rotated counterclockwise, by between output end 13 and intermediate ring 14
Apply pretightning force, roller 15 is allocated to the left side of planar section on 13 outer profile of output end by pusher dog 16, so that input terminal 12, roller
There is sufficiently large frictional force between 15 and output end 13, so that movement be made to pass to output end 13, revolves output end 13 counterclockwise
Turn, when control 4 power loss of electromagnet, pawl 2 is stuck on claw 17, and then roller 15 is dialled and leaves 13 planar portions of output end by pusher dog 16
