[0035] See also Figure 4 The limiting assembly 35 includes a pressing block 351, which is used to limit the wooden board. A rotating rod 352 is passed through and rotatably connected to the middle part of the pressing block 351, which is used to be connected to the connecting rod 34. In accordance with the angle change of the pressing block 351, the rotating rod 352 is rotatably connected to the connecting rod 34. A stud 353 is passed through and threadedly connected to the lower part of the pressing block 351, which is used to press the wooden board tightly and make the pressing block 351 clamp the wooden board.

[0038] Working principle: When in use, place the wooden board on the operating table 1 and then rotate the screw rod 36 according to the length of the wooden board, so that it drives the two sliders 32 connected thereto to move closer or farther away from each other. When the slider 32 moves, the electric telescopic rod 33 connected thereto will move accordingly, thereby driving the connecting rod 34 connected thereto and the limiting assembly 35 connected to the connecting rod 34 to move together. When the connecting rod 34 moves, the electric telescopic rod 33 and the slider 32 on the other side connected thereto will move accordingly. When the limiting assembly 35 reaches the two ends of the wooden board, turn on the electric telescopic rod 33 to drive the connecting rod 34 and the limiting assembly 35 connected thereto to move downward. When the pressing block 351 reaches a suitable height, rotate the rotating plate 355 to drive the stud 353 to rotate. As the stud 353 rotates, it will press against the wooden board with its fixing pad 354. As the stud 353 presses the wooden board tightly, the angle of the pressing block 351 will change. The pressing block 351 presses the wooden board. When the wooden board is fixed, the cylinder 52 is turned on to drive the mounting plate 53 connected thereto to move downward. The pressing roller 55 connected to the mounting plate 53 through the connecting seat 54 will move downward accordingly and press the middle section of the wooden board. Then the engraving machine is turned on to perform engraving operations on the wooden board. When the wooden board is engraved, the engraving machine body 4 will move back and forth along the guide rail 2 as required by the engraving. At the same time, the pressing assembly 5 connected to the guide rail 2 through the bottom plate 51 will also move accordingly to continuously press the wooden board to prevent it from slipping during engraving. At the same time, when the engraving machine is engraving, the dust collection device is turned on. When the dust removal assembly 6 moves, the brush strip 64 at its lower part will clean the floating dust and debris on the wooden board. The mounting pipe 63 on the dust collection head 62 is connected to the dust collection device through a hose, so that the dust collection head 62 has suction force to remove the waste dust and the like generated by the engraving.
