[0019] To enhance understanding of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described and introduced below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, not all embodiments, and are not intended to limit the embodiments in any way. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-2The present invention provides a technical solution: a multi-directional adjustable foldable and detachable floor grinding machine, including an upper support frame 3 and a lower support frame 13. The upper end of the upper support frame 3 is provided with a handle 1, and a quick-release pin 2 is provided at the connection between the handle 1 and the upper support frame 3. A frame angle adjustment rod 4 is provided between the upper support frame 3 and the lower support frame 13. A wheel 5 is provided in the middle of the lower support frame 13. A locking screw 14, an angle adjustment handle 6, and a wheel height adjustment handle 7 are provided at the connection between the lower support frame 13 and the wheel 5. A dust collection cover 9 is provided at the top of the lower support frame 13. A quick-release frame 8 is provided at the connection between the dust collection cover 9 and the lower support frame 13. A motor 10 is provided at the upper end of the dust collection cover 9, and a grinding guide wheel 12 is provided at the side end of the dust collection cover 9.

[0021] The quick-release pin 2 is equipped with a handle, which is used to change the position of the quick-release pin 2 and can limit the handle 1 to be fixed or loosened. When the connection between the handle 1 and the upper support frame 3 is loosened, it is convenient to adjust the height of the handle. No special tools are needed during the adjustment process, making the adjustment faster and suitable for people of different heights.

[0022] The frame angle adjustment rod 4 has a guide groove in the middle for adjusting the angle. This groove is used to change the position between the upper support frame 3 and the guide groove, and also to change the angle between the upper support frame 3 and the lower support frame 13. By adjusting the frame angle adjustment rod 4, the angle of the upper support frame 3 can be adjusted to different positions, thereby changing the angle relationship between the upper support frame 3 and the lower support frame 13, thus adapting to the height and usage habits of different people.

[0023] The wheel height adjustment handle 7 is used to adjust the height of the wheel 5, and the angle adjustment handle 6 is used to control the forward and backward movement of the wheel 5 and to control the angle of the wheel 5. The locking screw 14 is used to restrict the angle adjustment handle 6. By rotating the locking screw 14, the restriction of the angle adjustment handle 6 is released, and the angle of the wheel 5 can be adjusted by the angle adjustment handle 6. The height of the wheel 5 can be adjusted by the wheel height adjustment handle. According to the usage conditions at the application site, the positional relationship between the wheel 5 and the lower support frame 13 can be adjusted, so that the grinding machine can be more adapted to the actual on-site construction environment.

[0024] The dust collection hood 9 has a dust cover 11 on its side. The side of the dust collection hood 9 has a flat structure and is used to attach the dust collection hood 9 to the edge, which facilitates the grinding of the joint between the floor and the wall.

[0025] The quick-release frame 8 is used to position and connect the lower support frame 13 and the motor 10, and facilitates quick disassembly.

[0026] Although embodiments of the present invention have been shown and described, it should be emphasized that the above description is merely an introduction and description of the usage of the embodiments of the present invention, and is not intended to limit the present invention in any way. Those skilled in the art will understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
