The cylindrical grinding head 8 extends into the hemispherical grinding head 7 and is connected thereto.

[0022] During actual use, hold the grinding gun body 1 and start the motor. The rotation of the output end of the motor drives the rotation of the rotating column 4. The rotation of the rotating column 4 drives the rotation of the cylindrical grinding head 8. The rotation of the cylindrical grinding head 8 drives the rotation of the hemispherical grinding head 7. In this way, the grinding action can be completed, and both the cylindrical grinding head 8 and the hemispherical grinding head 7 can be replaced separately.

[0023] Embodiment 2

[0024] Please refer to Figure 3 - Figure 4, on the basis of the first embodiment, a cylindrical card slot 20 is provided on the hemispherical grinding head 7. Four rectangular card slots 18 are evenly provided on the side of the cylindrical card slot 20. The cylindrical card slot 20 communicates with the rectangular card slots 18. A second threaded hole 19 is provided at one end of the cylindrical card slot 20, and the inner wall of the second threaded hole 19 is provided with threads. One end of the cylindrical grinding head 8 is fixedly connected with a cylindrical card block 22 and a rectangular card block 21. The rectangular card blocks 21 are evenly arranged around the cylindrical card block 22 and fixedly connected thereto. The cylindrical card block 22 is adapted to the cylindrical card slot 20, and the rectangular card block 21 is adapted to the rectangular card slot 18. A second screw 23 is provided on the cylindrical card block 22. The threaded end of the second screw 23 is adapted to the threads in the threaded hole. The second screw 23 passes through the cylindrical card block 22 and is slidably connected thereto. The second screw 23 can be rotated by a screwdriver.

[0025] A first slideway 13 is provided at one end of the second screw 23. The second screw 23 can be inserted into the cylindrical card block 22 through the first slideway 13. The first slideway 13 penetrates one end of the cylindrical grinding head 8. The upper and lower second screws 23 need to pass through the first slideway 13. Four rectangular slideways 9 are evenly provided on one side of the first slideway 13. The first slideway 13 communicates with the four rectangular slideways 9. A first threaded hole 14 is provided between every two rectangular slideways 9. The first threaded hole 14 is provided at one end of the cylindrical grinding head 8 and the first threaded hole 14 is provided with threads.

[0026] If you want to replace the hemispherical grinding head 7, you need to unscrew the second screw 23 through the first slideway 13 by using a screwdriver, then pull out the hemispherical grinding head 7, align the new hemispherical grinding head 7 and install it on the cylindrical grinding head 8, and then install the second screw 23 again through the first slideway 13 by using a screwdriver, so that it passes through the cylindrical card block 22 and is threadedly connected to the second threaded hole 19.

[0027] Embodiment Three

[0028] Please refer to Figure 2, on the basis of the second embodiment, one end of the rotating column 4 is fixedly connected with four first sliders 10. While the rotating column 4 is slidably connected with the first slideway 13, the four first sliders 10 are respectively slidably connected with the four rectangular slideways 9. A first disc 16 is slidably sleeved on the rotating column 4. The first disc 16 is arranged on one side of the first slider 10. A second disc 17 is fixedly sleeved on the rotating column 4. A spring 12 is fixedly connected between the first disc 16 and the second disc 17. One end of the spring 12 is fixedly connected with one side of the first disc 16, and the other end of the spring 12 is fixedly connected with one side of the second disc 17. The spring 12 is slidably sleeved on the driving column. Four first screws 11 are arranged on the first disc 16. The four first screws 11 all penetrate through the first disc 16 and are threadedly connected with the first threaded holes 14. Thus, when the grinding gun head 3 works, once pressure is generated on the gun head, the spring 12 will contract. The rotating rod slides in the first slideway 13, and the first slider 10 will slide in the rectangular slideway 9. The first disc 16 will slide on the rotating column 4 along with the expansion and contraction of the spring 12. An inclined surface 15 is arranged on one side of each first slider 10. The arrangement of the inclined surface 15 makes the process of inserting the first slider 10 into the rectangular slideway 9 more convenient when the cylindrical grinding head 8 or the hemispherical grinding head needs to be replaced.

[0029] In actual use, hold the grinding gun body 1 to start the motor. When the output end of the motor rotates, it drives the rotating column 4 to rotate. The rotation of the rotating column 4 can drive the cylindrical grinding head 8 to rotate, and the rotation of the cylindrical grinding head 8 drives the hemispherical grinding head 7 to rotate. In this way, the grinding action can be completed. Both the cylindrical grinding head 8 and the hemispherical grinding head 7 can be replaced separately. If you want to replace the hemispherical grinding head 7, first, the cylindrical grinding head 8 needs to be removed. Then, use a screwdriver to unscrew the second screw 23 through the first slideway 13, and then pull out the hemispherical grinding head 7. Align the new hemispherical grinding head 7 and install it on the cylindrical grinding head 8. Then, use a screwdriver again through the first slideway 13 to install the second screw 23 so that it penetrates through the cylindrical clamping block 22 and is threadedly connected with the second threaded hole 19. When the cylindrical grinding head 8 needs to be replaced, the hemispherical grinding head and the cylindrical grinding head 8 also need to be removed first, and then after replacement, it is first connected to the hemispherical grinding head, and then connected to the rotating column 4 after connection.
