So when motor 13 rotates, drive third pivot 31 and rotate, and then drive the first belt pulley 21 of lower part and rotate, thereby drive first flat belt 22 and rotate, make the first belt pulley 21 on upper portion rotate, drive first pivot 20 and rotate, and then drive the second belt pulley 27 on upper portion and rotate, thereby drive the rotation of second flat belt 28, make the second belt pulley 27 of lower part rotate, drive second pivot 26 and rotate, and then drive blade 30 and rotate, blade 30 rotates and blows out the wind, the dust that will cut the plank blows to the right side, so can prevent that the dust from influencing user's work, can also protect user's health simultaneously.
Because the travel switch 32 is further included, the travel switches 32 are symmetrically arranged on the right side of the fourth slide rail 23 up and down, and the travel switches 32 are connected with the electric push rod 15 through a circuit. Therefore, when the fourth sliding block 24 moves downwards to be in contact with the travel switch 32, the travel switch 32 controls the electric push rod 15 to contract, at this time, the cutting wheel 14 just finishes cutting the wood board, when the fourth sliding block 24 moves upwards to be in contact with the travel switch 32, the travel switch 32 controls the electric push rod 15 to stop working, and at this time, the electric push rod 15 just resets.
The above examples are merely representative of preferred embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, various changes, modifications and substitutions can be made without departing from the spirit of the present invention, and these are all within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
