Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment, the present invention is described in further details.
Attached drawing 1-3 is rotating clamp of the present invention, including mounting plate 1；The lower surface of the mounting plate 1 is arranged
There is clamping device 2；The clamping device 2, including rotating disk 21 and passive turntable 22；The lower surface of the rotating disk 21 is provided with
Circular groove（It does not mark）；It is evenly equipped with internal tooth on the inner wall of the circular groove；Multiple internal tooths are evenly equipped in the circular groove
Wheel 24；The internal gear 24 respectively with interior tooth engagement；Internal gear rotary shaft 25 is provided on the internal gear 24；It is described by turn
Disk 22 is arranged in rotating disk 21, closed circle groove；The internal gear rotary shaft 25 passes through passive turntable 22, the internal gear
The outer end of rotary shaft 25 is arranged with pinch wheels 23；The internal gear rotary shaft 25 is located at the bias of corresponding pinch wheels 23
Position；When rotating disk 21 rotates, the pinch wheels 23 can turn to the rotation center of rotating disk 21 simultaneously.
Electric rotating machine 4 is provided on the mounting plate 1；The electric rotating machine 4 drives rotating disk 21 around its vertical rotation
