the rotating threaded sleeve 18 drives the threaded rod 19 to move rightwards, the threaded rod 19 drives the connecting rod 21 to move rightwards, and when the connecting rod 21 drives the moving plate 22 to move rightwards to the center of the wood board, the telescopic motor 17 is turned off;

the cutting motor 24 is started, the cutting motor 24 drives the motor shaft 25 to rotate at a high speed, the rotating motor shaft 25 drives the first cutting wheel 26 to rotate, the rotating first cutting wheel 26 drives the cutting chain 64 to perform high-speed transmission on the third cutting wheel 63 and the first cutting wheel 26, the moving motor 82 is started at the moment, the moving motor 82 drives the moving telescopic shaft 83 to descend, and therefore the cutting chain 64 on the mechanical plate 14 is driven to move downwards at a constant speed through the connecting block 89 to cut the wood plate;

when the width of the wood board is larger than the diameter of the first cutting wheel 26, the telescopic motor 17 is started in a reverse direction, the telescopic motor 17 drives the threaded sleeve 18 to rotate forwards, the threaded sleeve 18 rotating forwards drives the threaded rod 19 to move leftwards, so that the first cutting wheel 26 indirectly moves leftwards, the threaded sleeve 18 drives the main transmission wheel 20 to rotate, the main transmission wheel 20 drives the first transmission wheel 28 to rotate, the first transmission wheel 28 drives the second transmission wheel 32 to rotate, the second transmission wheel 32 drives the rotating shaft 30 to rotate, the second transmission wheel 32 drives the winding reel 33 to rotate, the second winding reel 35 is released, the first winding reel 34 is wound, the movable plate 58 drives the third moving shaft 57 to move downwards and rightwards for a certain distance, the telescopic motor 17 is turned off, the rope winding motor 45 is started again, the rope winding motor 45 drives the rope winding motor shaft 46 to rotate forwards, the rope winding motor shaft 46 rotating forwards drives the rope winding reel 47 to, the pulling rope 48 pulls the first moving shaft 51 to slide downward in the first shaft groove 50, the first spring 54 is compressed, at the same time, the rotating transmission gear 49 drives the sector gear 44 engaged with the transmission gear 49 to rotate backward, the sector gear 44 drives the rope winding shaft 42 to rotate backward, the rotating rope winding shaft 42 winds the connecting steel rope 39, so that the rotation shaft 30 moves upward in the first transmission wheel 28, the second transmission wheel 32 is disengaged from the first transmission wheel 28, the backward rotation rope reel 42 is rotationally restored forward by the action of the clockwork spring 41, the rope reel 42 is always wound around the connecting steel rope 39 due to the obstruction of the rotating transmission gear 49, the second transmission wheel 32 is always disengaged from the first transmission wheel 28, when the first moving shaft 51 is pulled to a proper position by the pulling rope 48, the rope winding motor 45 is turned off, and then the telescopic motor 17 and the moving motor 82 are started to cut the clamped wood.

The above embodiments are merely illustrative of the technical concept and features of the present invention, and the purpose of the embodiments is to enable those skilled in the art to understand the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
