However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] The effect achieved by the entire embodiment 1 is that when the PEDG board is cut, it is first placed on the storage plate 2, and then the four pressure rods 303 are rotated to make it above the PETG board, and the pressure rods 303 are rotated to stagger them with the cutting line on the PETG board, and then the pressure rods 303 are slid downward and then the fastening nuts 305 are rotated and tightened so that the bottom of the pressure rods 303 is pressed against the pressure rods 303, thereby fixing the pressure rods 303. At this time, the second meshing sleeve 304 at the bottom of the pressure rods 303 is meshed with the first meshing sleeve 302 on the surface of the screw rod 301, so that the pressure rods 303 cannot rotate, thereby fixing the PETG board from top to bottom, and the firmness is relatively high. The structure is simple and easy to operate, and the overall cutting efficiency is improved. The support 1 is provided to support the workbench 11 to make it off the ground. The model of the cross slide 12 is FWTBD, which is mainly used to drive the storage plate 2 to perform horizontal or vertical linear motion on the plane. The rubber pad 306 provided at the bottom of the pressure rod 303 is mainly used to increase the friction between the pressure rod 303 and the PETG plate, thereby improving the fixing effect. After the PETG plate is fixed, the movable frame 42 is driven to move downward by starting the cylinder 43, so that the cutting machine 504 moves to a suitable position to cut the PETG plate.

[0025] Embodiment 2, as Figure 1-Figure 4As shown, an adjustment mechanism 5 is provided at the top of the top frame 41, and the adjustment mechanism 5 includes a servo motor 501 and a rotating block 503. The servo motor 501 is fixedly installed at the top center of the top frame 41, and the output end of the servo motor 501 slides through the outer surface of the top frame 41 and extends to the bottom. The output end of the servo motor 501 is fixedly connected to a telescopic rod 502, and the rotating block 503 is rotatably connected to the bottom of the movable frame 42. A cutting machine 504 is installed at the bottom of the rotating block 503, and the bottom of the telescopic rod 502 slides through the outer surface of the movable frame 42 and is connected to the top of the rotating block 503. An anti-slip pad 21 is provided on the top of the storage plate 2.

[0026] The effect achieved by the entire embodiment 2 is that when the cutting machine 504 cuts the PETG board, the cutting machine 504 is adjusted to a suitable height, and the PETG board is driven to move forward and backward by the cross slide 12 to complete the longitudinal cutting of the PETG board. At the same time, when the PETG board needs to be cut horizontally, the servo motor 501 is started to drive the telescopic rod 502 to rotate 90°, and the electric telescopic rod 502 synchronously drives the rotating block 503 and the cutting machine 504 to rotate, thereby changing the direction of the cutting machine 504. Then, the cross slide 12 drives the PETG board to move left and right to complete the horizontal cutting. Horizontal cutting can complete cutting operations in different directions without repeated adjustments, which simplifies the operation steps and improves the cutting efficiency. The output end of the servo motor 501 and the rotating block 503 are connected by setting a telescopic rod 502, so that when the cylinder 43 drives the movable frame 42 and the cutting machine 504 to rise and fall, the distance between the servo motor 501 and the cutting machine 504 can be synchronously changed by the telescopic rod 502, and at the same time, it does not affect the servo motor 501 to adjust the direction of the cutting machine 504. By setting an anti-skid pad 21 on the storage plate 2, the anti-skid effect is improved, so that the PETG plate is not easily displaced.

[0027] Working principle: When cutting the PEDG board, first place it on the storage plate 2, then rotate the four pressure rods 303 to make it above the PETG board, and rotate the pressure rod 303 to make it staggered with the cutting line on the PETG board, then slide the pressure rod 303 downward and rotate and tighten the fastening nut 305 so that its bottom presses the pressure rod 303 firmly, thereby fixing the pressure rod 303. At this time, the second engagement sleeve 304 at the bottom of the pressure rod 303 is engaged with the first engagement sleeve 302 on the surface of the screw rod 301, so that the pressure rod 303 cannot rotate, thereby fixing the PETG board from top to bottom, with high firmness, and no need to adjust the pressure rod 303 for the second time later, with simple structure and convenient operation, thus improving the overall cutting efficiency. After the PETG plate is fixed, the movable frame 42 is driven downward by starting the cylinder 43, so that the cutter 504 is moved to a suitable height, and the PETG plate is driven to move forward and backward by the cross slide 12 to complete the longitudinal cutting of the PETG plate. At the same time, when the PETG plate needs to be cut horizontally, the servo motor 501 is started to drive the telescopic rod 502 to rotate 90°, and the electric telescopic rod 502 synchronously drives the rotating block 503 and the cutter 504 to rotate, thereby changing the direction of the cutter 504. Subsequently, the PETG plate is driven to move left and right by the cross slide 12 to complete the horizontal cutting. The cutting operation in different directions can be completed without repeated adjustment, which simplifies the operation steps and further improves the cutting efficiency.
