[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-6 This utility model provides a technical solution: a wood sanding and polishing machine capable of multi-angle trimming, comprising a base plate 1, a first fixing plate 2, a first connecting shaft 3, a mounting plate 4, a first electric telescopic rod 5, a limiting plate 6, a connecting disc 7, a connecting port 8, a protrusion 9, a second connecting shaft 10, a first motor 11, a second fixing plate 12, a first rotating shaft 13, a second motor 14, a first adjusting component 15, a second adjusting component 16, a second rotating shaft 17, a support plate 18, a second electric telescopic rod 19, a mounting frame 20, a threaded rod 21, a third motor 22, an adjusting plate 23, and a polishing stone 24.

[0034] Example 1: Currently, sanding the right end of a wooden board requires manual flipping to sand the other surfaces, which is cumbersome, time-consuming, and labor-intensive. Therefore, this example uses the following technical solution: Figure 1 , Figure 3 and Figure 4Since the adjustment structure includes a first connecting shaft 3, a mounting plate 4, a first electric telescopic rod 5, a limiting plate 6, a connecting disc 7, a connecting port 8, a protrusion 9, a second connecting shaft 10, and a first motor 11, the limiting plate 6 is telescopically mounted on the upper side of the base plate 1 via the mounting plate 4. The protrusion 9 is angularly embedded and connected to the left end of the second connecting shaft 10. The limiting plate 6 is rotatable on the upper side of the base plate 1 via the protrusion 9 and the connecting port 8. Therefore, placing the wooden board on the upper side of the support plate 18 allows the left and right sets of first electric telescopic rods 5 to work and drive the corresponding limiting plates 6. The two sides move closer together until the inner walls of the symmetrically arranged limiting plates 6 are tightly attached to the left and right ends of the wooden board. The first motor 11 drives the second connecting shaft 10 to rotate at the upper end of the second fixed plate 12. When the second connecting shaft 10 rotates, it drives the unequally angled protrusions 9 to rotate, so that the protrusions 9 are nested and connected inside the connecting port 8 when they rotate. The first connecting shaft 3 is driven to rotate on the first fixed plate 2 through the connecting plate 7. When the first connecting shaft 3 rotates, it drives the wooden board to rotate through the mounting plate 4 and the limiting plate 6, thereby adjusting the angle of the wooden board and facilitating multi-angle trimming.

[0035] Example 2: In existing methods of sanding wood boards, the boards are prone to instability, affecting the sanding quality. Therefore, this example addresses this issue by implementing the following technical solution: Figure 1 and Figure 2 The support structure includes a first rotating shaft 13, a second motor 14, a first adjusting member 15, a second adjusting member 16, a second rotating shaft 17, and a support plate 18. The lower ends of the two sets of first adjusting members 15 are meshed together, and the upper ends of the two sets of second adjusting members 16 are meshed together. The support plate 18 is in a lifting structure on the upper side of the base plate 1 through the first adjusting members 15 and the second adjusting members 16. Therefore, when the second motor 14 is working, it drives the first rotating shaft 13 on the front side to rotate. When the first rotating shaft 13 on the front side rotates, it drives the first adjusting member 15 on the front side to rotate. When the two sets of first adjusting members 15 are meshed together, they drive the second adjusting members 16 that are symmetrically arranged in front and behind to rotate. When the upper ends of the two sets of second adjusting members 16 are meshed together, the second rotating shaft 17 that is symmetrically arranged in front and behind rotates on the support plate 18. The support plate 18 is driven to rise through the first adjusting members 15 and the second adjusting members 16 that are symmetrically arranged in front and behind until the upper end of the support plate 18 is attached to the lower end of the wooden board, which makes it easier to support the wooden board and increase stability during sanding.

[0036] Example 3: Existing methods for sanding wood boards use electric push rods, sanding discs, and other components. However, sanding wood boards of different sizes is cumbersome. Therefore, this example uses the following technical solution: Figure 1 , Figure 2 , Figure 5 and Figure 6Since the threaded rod 21 is threaded inside the upper end of the adjusting plate 23, the polishing stone 24 slides on the lower side of the mounting frame 20 through the adjusting plate 23 and the threaded rod 21. Therefore, when the second electric telescopic rod 19 is working, it drives the mounting frame 20 to descend, allowing the lower end of the polishing stone 24 to fit against the upper end of the wooden board. When the third motor 22 is working, it drives the threaded rod 21 to rotate on the mounting frame 20. Through the mounting frame 20 and the adjusting plate 23, the polishing stone 24 can slide left and right on the upper end of the wooden board, so that the polishing stone 24 polishes the wooden board, thus facilitating the polishing of wooden boards of different sizes. All the electrical components mentioned above are existing technologies and will not be described in detail here.

[0037] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
