Abstract
A directly driven power swing rod device without dead points includes a control rod provided with a coordinate rod base, two L-shaped frames respectively provided with a hole base having a bearing fixed therein, two motors respectively provided with a position detecting coder for receiving a coordinate message and transmitting it to a control device which is able to control the rotating angles of the motor shafts respectively connected with the two L-shaped frames, a first interacting member inserted through a guide hole of the coordinate rod base and secured with the first L-shaped frame, and a second interacting member having one end inserted in a positioning hole of said coordinate rod base and the other end connected with the second L-shaped frame. Then the control rod may be deflected by the motors for driving a high speed, sensitive response system.
