Tool referred to and driven using single-power, has the advantages that to capture that object adaptive faculty is strong and simple structure.
In addition, sheave is arranged on mechanism's support plate in motor-driven mechanism, sheave motor is arranged on mechanism's support plate,
Sheave motor drives sheave to do the motion of six gap rotations in a circumference by rocking arm, on sheave support wheel
Steel wire motor equally do gap rotation;Six groups of travelling gears, cone tooth, the combinations of steel wire runner are separately mounted to hexagonal plate
On six angles, steel wire motor has six stops according to sheave slot number, each time at stop place with six groups in it is any one
The travelling gear engagement of group, the travelling gear of the group pass through cone tooth combination and drive the steel wire runner of the group to rotate, and then driving is somebody's turn to do
Organize drawing for the steel wire on steel wire runner;Move in one week in sheave, six steel wire runners are driven once successively, and in quilt
In driving time, the corner and rotating speed of the moment of torsion of regulation motor and rotating speed independent control each steel wire runner, and then using very
Few motor drives multiple steel wire runner motions by sequencing contro, and then drives the dilatory of multiple steel wires, such that it is able to control
The multivariant mechanical finger driven based on steel wire.Present invention uses sequencing contro, greatly reduces the complexity of structure,
With preferable practical function.
