[0026] Working principle:

[0027] Auxiliary fixing process of wood when cutting wood to prevent accidental injury from electric saw:

[0028] The operator places the wood between the two plywoods 306, connects the external power supply of the second hydraulic cylinder 301, starts the extension of the telescopic end of the second hydraulic cylinder 301, drives the push block 303 to move to the right, and the push block 303 drives the connecting rod 304 to move. The connecting rod 304 pulls the bent rods 305 on both sides close to each other, and the bent rods 305 drive the plywood 306 to move synchronously. After the surface of the plywood 306 contacts the surface of the wood, the wood is fixed, which makes it convenient for the subsequent operator to control the electric saw body 9 to cut the wood, completing the auxiliary fixing process of the wood when the electric saw is cutting the wood to prevent accidental injury, and avoid the wood from sliding during cutting.

[0029] Auxiliary protection process to prevent accidental injury when cutting wood with an electric saw:

[0030] The operator connects the external power supply of the first hydraulic cylinder 201, starts the extension of the telescopic end of the first hydraulic cylinder 201, and drives the push plate 203 to move to the right. The push plate 203 drives the baffle 204 to move upward through the cooperation of the arc groove opened on the surface and the pulley on the surface of the baffle 204. When the baffle 204 moves upward, the spring 206 contracts and acts as an auxiliary force. After the push plate 203 moves to the limit position, it drives the baffle 204 to rise to the limit position. The grooves processed on the surface of the baffle 204 make it convenient for the operator to control the electric saw body 9 to cut the wood, completing the auxiliary protection process to prevent accidental injury when the electric saw is cutting wood. When the chain of the electric saw body 9 is damaged, the chain will bounce on the surface of the baffle 204 and will not cause damage to the operator.

[0031] Prevent accidental injury to the wood cutting process of the electric saw:

[0032] Connect the external power supply of the electric saw body 9, start the electric saw body 9 to make the chain of the electric saw body 9 rotate, then connect the external power supply of the motor 4, start the output shaft of the motor 4 to rotate and drive the threaded rod 5 to rotate, the threaded rod 5 drives the threaded block 6 to move downward, the threaded block 6 drives the fixed block 7 to move synchronously, the fixed block 7 drives the electric saw body 9 to rotate through the moving rod 8, so that the chain of the electric saw body 9 cuts the wood, completing the wood cutting process of the electric saw to prevent accidental injury.
