Sequence of mechanical actions of the whole device:

1: the pull rod 34 is pulled rightwards, so that the pull block 38 and the limiting block 29 are driven to move rightwards, the telescopic spring 39 is stretched, after the moving position of the limiting block 29 is determined, the thread block 33 is rotated until the thread block 33 is contacted with the right end face of the cutting table 10 again, the pull rod 34 is loosened, the position of the limiting block 29 is determined at the moment, and therefore the distance between the vertical plane where the cutting wheel 23 is located and the vertical plane where the limiting block 29 is located is determined;

2: the driving motor 44 is operated to rotate the driving shaft 15, so as to rotate the driving wheel 52 and the pushing wheel 16, the rotation of the pushing wheel 16 drives the floor 14 to move to the right, so as to drive the driving wheel 12 to rotate, so as to drive the driving shaft 11 and the rotating gear 47 to rotate, so as to drive the rotating gear 48 and the rotating shaft 49 to rotate, so as to drive the rotating disc 71 to rotate, so that the ejecting block 73 leaves the ejecting slot 72 under the action of centrifugal force and the ejecting spring 74 is stretched, so that the ejecting block 73 drives the lower pressing plate 51 to descend, so as to drive the lower pressing rod 53 and the connecting shaft 54 to descend, so as to separate the connecting wheel 46 from the driving wheel 52 and the friction wheel 62, the descending of the lower pressing plate 51 causes the lower pressing spring 50 to be compressed, after the floor 14 moves to the right and contacts the limiting block 29, the pushing wheel 16 can not drive the floor 14 to move to the, so that the rotating gear 47 and the transmission shaft 11 are not rotated any more, and the rotating gear 48 and the rotating shaft 49 are not rotated any more, and the rotating disc 71 is not rotated any more, so that the ejection block 73 is reset under the action of the ejection spring 74, and the push-down spring 50 is reset, and the push-down plate 51 is driven to ascend, and the push-down rod 53 and the connecting shaft 54 are driven to ascend, so that the connecting wheel 46 is again contacted with the driving wheel 52 and the friction wheel 62;

3: at this time, the wood board is located right below the cutting wheel 23, the rotation of the driving wheel 52 drives the connecting wheel 46 to rotate, thereby driving the friction wheel 62 to rotate, thereby driving the friction shaft 64 and the winding wheel 65 to rotate, the chain 17 is wound tightly and the torsion spring 63 is twisted, the chain 17 drives the driving spring block 27 to descend first, when the supporting spring 28 is compressed to the utmost, the ascending and descending block 26 descends along with the descending block 26, thereby the lower end of the cutting wheel 23 is located at the rear side of the floor 14, when the ascending and descending block 26 descends to contact with the upper end face of the floor 14, the lower pressure block 43 stops working, at this time, the limiting spring 56 is compressed and the limiting block 55 and the connecting rod 60 both descend, the cutting motor 20 works to drive the cutting shaft 24 to rotate, thereby driving the cutting wheel 23 and the driven gear 67 to rotate, the rotation of the driven gear 67 drives the moving gear 70 and the pushing shaft 69 to rotate, the moving gear 70 drives the right slide block, when the cutting shaft 24 and the left sliding block 19 move forwards, the cutting wheel 23 rotates once and moves forwards, cutting is started after the cutting wheel 23 is contacted with the floor 14, and dust and debris generated by cutting are separated by the lifting block 26 and enter the containing cavity 40;

4: the connecting rope 37 is pulled in the process of descending the lifting block 26, so that the lifting block 32 descends, the lifting spring 35 is compressed, so that the limit block 29 descends and returns to the lifting cavity 30, the right end of the floor 14 is not contacted with the limit block 29 in the process of cutting the wood board by the cutting wheel 23, after the cutting is finished, the cutting motor 20 works to drive the cutting shaft 24 to rotate reversely, so that the driven gear 67 rotates reversely, so that the moving gear 70 and the pushing shaft 69 rotate reversely, so that the sliding block 19 moves backwards and resets, after the sliding block 19 resets, the cutting motor 20 stops working, at the moment, the driving motor 44 works again to drive the driving shaft 15 to rotate, so that the driving wheel 52 and the pushing wheel 16 rotate again, the rotation of the pushing wheel 16 drives the floor 14 to move rightwards continuously, so that the driving wheel 12 starts to rotate again, so that the transmission mechanism 75 works again, so that the connecting wheel 46 is separated from the driving wheel, at this time, due to the separation of the connecting wheel 46 and the friction wheel 62, the limiting spring 56, the torsion spring 63 and the supporting spring 28 are reset, the reset of the torsion spring 63 drives the friction shaft 64 to rotate, thereby driving the friction wheel 62 and the winding wheel 65 to rotate and reset, thereby enabling the winding wheel 65 to loosen the chain 17, the reset of the limiting spring 56 drives the connecting rod 60 and the limiting block 55 to move upwards, thereby enabling the lifting block 26 to move upwards, the reset of the supporting spring 28 drives the spring block 27 to move upwards and reset, due to the rising of the lifting block 26, the connecting rope 37 is loosened, thereby enabling the lifting spring 35 to slowly reset under the condition of slowly overcoming the friction force between the lifting block 32 and the lifting cavity 30, thereby driving the lifting block 32 to slowly rise, and when the floor 14 moves rightwards, driving the cut floor 14 to move rightwards after passing through the upper side of the limiting block 29, the limiting block 29 enters the external space, so that the cut floor 14 is jacked up, meanwhile, the uncut floor 14 is limited, at the moment, the floor 14 contacted with the driving wheel 12 stops rotating again, the driving mechanism 75 stops working again, so that the connecting wheel 46 is reset and contacted with the driving wheel 52 and the friction wheel 62 again, the next cutting is started, and the length of the floor which is cut at the previous time is equal to that of the floor which is cut at the previous time;

5: when the lifting block 32 descends, the hemp rope 36 loosens, so that the compression spring 58 is reset, the triangular block 59 is driven to move backwards, chips in the cutting process of the cutting wheel 23 fall to the front side of the triangular block 59, when the lifting block 32 ascends, the hemp rope 36 is pulled, the triangular block 59 is driven to move forwards, the compression spring 58 is stretched, and therefore the triangular block 59 moves forwards to push the chips out of the containing cavity 40 in the cutting process, and accumulation is prevented.
