By placing the wooden board on the fixing table 4 and fitting the wooden board with the edge banding strip 17, and by connecting the right end of the limit rod 10 to the motor, the limit rod 10 can slide inside the mounting seat 8, and the thread groove 11 will have a threaded reaction inside the other group of mounting seats 8, so that the limit rod 10 can slide to the outside of the mounting seat 8.

[0027] For further information, see Figure 1 , Figure 2 and Figure 3 In this embodiment, the end of the connecting rod 9 away from the mounting seat 8 is rotatably connected to the support plate 12, the outside of the limiting rod 10 is fixedly connected to the moving block 13, the top of the moving block 13 is rotatably connected to the extension rod 14, and the end of the extension rod 14 away from the moving block 13 is rotatably connected to the left side of the top of the support plate 12. When the limiting rod 10 moves to the outside of the mounting seat 8, the moving block 13 moves with the limiting rod 10, and then drives the extension rod 14 to swing. At the same time, the support plate 12 follows the swing through the connecting rod 9, and then the support plate 12 tilts at an angle.

[0028] For further information, see Figure 1 , Figure 2 and Figure 3 In this embodiment, a first rotating disk 15 is rotatably connected to the middle of the top of the support plate 12, a winding shaft 16 is fixedly connected to the middle of the first rotating disk 15, an edge banding strip 17 is sleeved on the outside of the winding shaft 16, an unwinding shaft 18 is fixedly connected to the end of the edge banding strip 17 away from the first rotating disk 15, and a second rotating disk 19 is fixedly connected to the outside of the unwinding shaft 18. The support plate 12 is tilted at an angle to achieve the following movement of the first rotating disk 15, and the winding shaft 16 follows the movement of the first rotating disk 15, thereby stretching the edge banding strip 17 to achieve a taut state and better fit with the wooden board. At the same time, the winding shaft 16 is rotated to achieve the movement of the edge banding strip 17 and the rotation of the second rotating disk 19.

[0029] For further information, see Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, a positioning shaft 20 is rotatably connected to the middle of the edge banding strip 17 and located at the top of the fixed platform 4.
