[0050] The grinding assembly is used for grinding the wall surface, including:

[0051] The supporting roller shaft 302-1 and the transmission roller shaft 301 are arranged on the side of the main body 1 away from the side plate 101;

[0052] The grinding belt 302 is mounted on the outside of the supporting roller 302-1 and the transmission roller 301;

[0053] Specifically, the support roller shaft 302-1 and the transmission roller shaft 301 are rotatably mounted on the main body 1 through the bracket 302-2;

[0054] When using:

[0055] The two supporting rollers 302-1 and the transmission roller 301 are arranged in a triangle in the horizontal direction;

[0056] The function of the other supporting roller 302 - 1 is to adjust the tension of the grinding belt 302 and prevent the grinding belt 302 from rubbing against the main body 1 ;

[0057] Moreover, the transmission roller 301 rotates to drive the grinding belt 302 to move, and the transmission is achieved by using a belt, a pulley or a gear or a chain. This is due to the existing technology, and its detailed structure, working principle, and transmission method are not described in detail.

[0058] The motor 3 is arranged on the end surface of the main body 1 and is mounted with the bracket 302-2. The motor 3 is driven by the shaft of the transmission roller 301;

[0059] The dust collection component includes a dust collection fan 4, which is arranged on the end surface of the main body 1 away from the motor 3, and a dust collection port 401 is provided at its output end;

[0060] Specifically, the dust suction port 401 is connected to the output end of the dust suction fan 4 through an air duct, and the outer wall of the air duct is provided with a metal hose for easy adjustment;

[0061] More specifically, the metal hose can adaptively fix its position after the user changes its position, making it easy to adjust the position of the suction port 401.

[0062] During operation, the user moves the main body 1 by means of the handrail 102, places the included sanding belt 302 on the wall surface to be sanded, starts the motor 3, drives the sanding belt 302 to move via the transmission roller 301 shaft, and completes the sanding of the wall surface. At the same time, the dust suction fan 4 is started to absorb and clean the dust generated by the sanding belt 302 when sanding the wall surface through the dust suction port 401;

[0063] Among them, the user can replace different grinding belts 302 to adapt to different walls to be polished. Since the two corners of the grinding belt 302 away from the main body 1 are set at acute angles, the corners of the wall can be polished without the need for additional processing by the staff.

[0064] Please refer to Figures 1-8 As shown, as another embodiment of the present invention, a support assembly for the above-mentioned grinding assembly is provided, which can improve the user experience of the above-mentioned grinding assembly (the user does not need to lift the grinding assembly with effort), and includes:

[0065] Telescopic gas rod 2, adopts multi-stage telescopic rod and has air pressure slow contraction function;

[0066] That is, the end of the telescopic gas rod 2 can be extended and retracted as the user moves and plays a supporting role;

[0067] The telescopic gas rod 2 and the main body 1 are assembled through a first connecting component and a second connecting component;

[0068] The end of the telescopic gas rod 2 away from the main body 1 is provided with a walking wheel 201;

[0069] Specifically, the distribution forms of the running wheels 201 include single-axle (connecting axle) single wheel and single-axle (connecting axle) double wheels;

[0070] The first connecting component adopts a mounting sleeve 1-1, which is arranged at the bottom of the main body 1 and fixedly connected to the main body 1;

[0071] The end of the telescopic gas rod 2 away from the running wheel 201 is inserted into the mounting sleeve 1-1 and fixed;

[0072] The second connection component includes:

[0073] The fastening screw 101 - 1 is arranged perpendicular to the side wall of the side plate 101 and is fixedly installed with the side plate 101 ;

[0074] The rotating sleeve is rotatably arranged on the outside of the fastening screw 101-1 and is fixedly connected to the end of the telescopic gas rod 2;

[0075] Specifically, the rotating sleeve and the fastening screw 101 - 1 are fastened by a fastening nut;

[0076] That is, the user puts the rotating sleeve on the outside of the fastening screw 101-1 and presses the rotating sleeve to the side wall of the side plate 101 through the fastening nut to fix it;

[0077] The other components are the same as those in the above embodiment.

[0078] When in use, the staff fixes one telescopic gas rod 2 under the main body 1 through the mounting sleeve 1-1, and fixes the other telescopic gas rod 2 on the side plate 101 through the rotating sleeve, and adjusts the relative angle of the axes of the two telescopic gas rods 2 so that they are arranged at an angle. The two telescopic gas rods 2 are located away from the walking wheels 201 of the main body 1 and are on the ground. The staff moves the main body 1, thereby driving the grinding parts to move and grind the wall;
