the first trapezoidal slide rail, the second trapezoidal slide rail, the third trapezoidal slide rail and the fourth trapezoidal slide rail are in right trapezoid shapes; the inner sliding grooves of the first restraining shaft sleeve and the second restraining shaft sleeve are in an isosceles trapezoid shape.
7. The apparatus of claim 5, wherein the lower mechanism further comprises a buffer channel, a hook slot and a hook;
the hook groove is fixed below the lower-layer shell; the buffer channel is arranged below the lower-layer shell, the hook is fixed above the buffer channel, and the hook is respectively hooked with the hook groove.
8. The apparatus of claim 7,
the hook groove with the couple is 5 respectively, hook groove evenly distributed in the below of lower floor's shell.
9. The apparatus of claim 1,
the clamping jaw parts are 3 and are spaced by 120 degrees in pairs.
10. A method of extracting a twisted coconut, the method comprising:
presetting coconuts between the clamping jaws; then the motor drives the motor gear to rotate clockwise, the motor gear drives the outer teeth to rotate anticlockwise, and therefore the upper layer outer shell and the inner teeth are driven to rotate anticlockwise relative to the middle layer mechanism; the internal teeth rotate anticlockwise to drive the transmission straight gear to rotate anticlockwise, and the racks drive the clamping jaws to slide inwards; after the coconuts are clamped, the rack stops sliding, and the transmission straight gear stops rotating;
after the transmission straight gear stops rotating, the motor continues to rotate clockwise, the upper layer mechanism drives the middle layer mechanism to rotate anticlockwise together, and the clamping jaw is driven to screw off the preset coconut in a rotating mode;
when the preset coconut is unscrewed, the motor rotates reversely to drive the external teeth to rotate clockwise, so that the upper shell and the internal teeth are driven to rotate clockwise relative to the middle layer mechanism; the clockwise rotation of internal tooth drives transmission spur gear clockwise rotation, the rack drives the clamping jaw and outwards slides, predetermines the coconut and falls down, through buffer channel obtains safe recovery.
