Cleft hand is driven to extend into or out circular cavity.Above-mentioned drag ring rotates a circle, and one section of rack and pinion engagement is primary, gear rotation
Angle is fixed, and the angle of column spinner rotation is fixed, and column spinner drives the linear movement of the first telescopic rod, and the first telescopic rod drives center
Disk linear movement, spider drive all sliding blocks along round cavity wall sliding, and in turn, three or more cleft hands open or close up.
Above-mentioned drag ring can substitute for gear ring, and matched, friction pulley can be substituted with gear.
The pedestal includes chassis and top plate, and rotary sleeve and column spinner are articulated in top plate;The first guiding is opened up on chassis
Protrusion is equipped on the side wall of hole and the second pilot hole, the first pilot hole and the second pilot hole, the first telescopic rod and second stretch
Axial notch is opened up on bar side wall, the first telescopic rod is plugged in the first pilot hole, and the protrusion of the first pilot hole is stretched with first
The axial notch of contracting bar cooperates, and the second telescopic rod is plugged in the second pilot hole, the protrusion of the second pilot hole and the second telescopic rod
Axial notch cooperation.Under the guiding of the first pilot hole, the first telescopic rod moves linearly, similarly, in the second pilot hole
Under guiding, the second telescopic rod moves linearly.
