DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-4 , which includes a first support column 6. On both sides of the upper end of the first support column 6, bumps are symmetrically arranged. The inner wall of the bump is rotatably connected to a first rotating shaft 7. A rotating block 8 is fixed on the surface of the first rotating shaft 7, and the rotating block 8 is arranged at the center of the upper end of the first support column 6. The rotating block 8 can rotate with the first rotating shaft 7. A circular hole is formed on the surface of the rotating block 8, so that the hollow rotating cylinder 9 is rotatably installed in the circular hole formed on the rotating block 8. The tool clamping column 10 is fixed on the inner wall surface of the hollow rotating cylinder 9, and the length of the tool clamping column 10 is greater than the length of the hollow rotating cylinder 9. One end of the tool clamping column 10 is provided with an opening for placing a woodworking tool. A threaded groove is arranged at the upper end of the opening of the tool clamping column 10, and a bolt is threadedly connected to the threaded groove, so that the bolt rotates in the threaded groove to fix the tool extending into the opening. A handle 11 is fixed at the other end of the tool clamping column 10. Rotating the handle 11 can make the tool clamping column 10 rotate with the hollow rotating cylinder 9, which is convenient for adjusting the grinding angle of the woodworking tool.

[0028] Four groups of jacks are circumferentially distributed on the surface of the hollow rotating cylinder 9. A long strip-shaped opening is formed on the upper end surface of the rotating block 8. A U-shaped plate 12 is fixed on the upper end of the rotating block 8. A long strip-shaped opening identical to that of the rotating block 8 is formed on the upper end surface of the U-shaped plate 12. The inner wall surfaces of both sides of the U-shaped plate 12 are rotatably installed with a second rotating shaft 19. A trigger 13 is fixed on the surface of the second rotating shaft 19. The trigger 13 can rotate with the second rotating shaft 19. A limiting column 14 is fixed at the lower end of the trigger 13, so that the limiting column 14 passes through the long strip-shaped opening formed on the upper end surface of the rotating block 8 and the U-shaped plate 12 and is inserted into the jack formed on the surface of the hollow rotating cylinder 9. A spring is fixedly installed on one side of the limiting column 14. The bottom of the spring is connected to the U-shaped plate 12, and the top of the spring is connected to the trigger 13. When the trigger 13 is pressed, the trigger 13 will rotate with the second rotating shaft 19 to lift the limiting column 14 upward, and then the handle 11 can be rotated. When the handle 11 rotates 90 degrees, the hollow rotating cylinder 9 will also rotate 90 degrees. Subsequently, due to the elastic force of the spring, the limiting column 14 is clamped into another jack on the surface of the hollow rotating cylinder 9 to limit the rotation of the tool clamping column 10.

[0029] A movable plate 5 is provided at the lower end of the first support column 6, and a cross plate 2 is provided at the lower end of the movable plate 5. The movable plate 5 is close to the cross plate 2, so that the cross plate 2 supports the movable plate 5. And a movable cabin 1 is provided at the lower end of the cross plate 2. The movable cabin 1 is a lidless cavity, and the cross plate 2 divides the movable cabin 1 into four areas. Spring columns 3 are fixed to the end faces of each area of the movable cabin 1, and the spring columns 3 are fixed to the movable plate 5. Since there is a certain space between the periphery of the movable plate 5 and the side wall of the movable cabin 1, the movable plate 5 can move inside the movable cabin 1, and after the movable plate 5 moves, it will be pulled back to its original position by the spring columns 3. The side wall of the movable cabin 1 is slightly higher than the upper end of the movable plate 5, and a baffle 4 extends from the part of the side wall of the movable cabin 1 higher than the movable plate 5 towards the movable plate 5, covering the upper part of the movable plate 5 to limit the movable plate 5 and prevent the spring columns 3 from tilting when the movable plate 5 moves. During work, the cutter head is pushed towards the grinding disc 18 by the handle 11. After grinding is completed, the handle 11 can be slowly released. Under the elastic action of the spring columns 3, the cutter head will automatically disengage from the grinding disc 18, and the handle 11 can be held by hand to move in the horizontal direction of the movable plate 5, which will increase the operability of the tool during grinding.

[0030] A chute is provided on one surface of the movable cabin 1, and a slider 15 is slidably connected to the chute. The slider 15 can move horizontally in the chute, so as to adjust the position of the slider 15. After the position adjustment is completed, the slider 15 can be fixed by the bolt on the back. A second support column 16 is provided at the upper end of the slider 15. A motor 17 is connected to the side wall of the second support column 16. A long strip-shaped opening is provided on the upper end surface of the second support column 16. A rotating shaft is provided inside the long strip-shaped opening. One end of the rotating shaft is connected to the output end of the motor 17, and a grinding disc 18 is fixedly installed on the surface of the rotating shaft. The motor 17 drives the rotating shaft and the grinding disc 18 to rotate, so as to perform the grinding action.

[0031] Working principle: Place the tool in the opening provided at one end of the tool clamping column 10, and twist the bolt at the opening above the tool clamping column 10 to fix the tool. Slide the slider 15 to adjust the distance between the grinding disc 18 and the tool, and twist the bolt to fix the slider 15 on the surface of the movable cabin 1. Start the motor 17, hold the handle 11 by hand, and lift the handle 11 up and down to rotate the first rotating shaft 7, which is used to adjust the grinding angle of the tool. Press the trigger 13 to rotate the handle 11, so as to adjust the grinding angle of the tool. Release the trigger 13. When the handle 11 rotates 90 degrees, due to the elastic force of the spring, the limit column 14 automatically snaps into the next jack on the surface of the hollow rotating cylinder 9 to limit the rotation of the tool clamping column 10. Push the handle 11 in all directions, and the movable plate 5 will move along with the movement direction of the handle 11, so that the grinding disc 18 contacts the tool for grinding.

[0032] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
