The inner end of the hinge block 7 is movably inserted into the first through hole 5. A chute 8 is formed in the middle of the hinge block 7. The positioning column 6 is movably inserted into the chute 8 and fixedly connected to the surface of the connecting seat 4.

[0039] In the embodiment of the present utility model, when in use, for example, when grinding on a flat wall surface, the hinge block 7 and the hinge seat 9 are pulled out from the first through hole 5 of the connecting seat 4 on the top of the grinding main body 2. At the same time, the chute 8 in the middle of the hinge block 7 moves along the positioning column 6 on the connecting seat 4, so that the side grinding block 3 can move and be flush with the grinding main body 2.

[0040] By setting the hinge structure, the side grinding block 3 can adjust the angle with the grinding main body 2 as the center, which is convenient for intensive grinding and convenient for connection and fixation, reducing the possible movement during grinding.

[0041] As Figure 2 and Figure 3 shown, as a preferred embodiment of the present utility model, the cross-sectional sizes of the hinge block 7 and the hinge seat 9 are both smaller than the cross-sectional size of the first through hole 5, and the position of the hinge seat 9 always corresponds to the position of the connecting seat 4 when the grinding main body 2 and the side grinding block 3 are parallel and perpendicular.

[0042] In the embodiment of the present utility model, when in use, by making the cross-sectional sizes of the hinge block 7 and the hinge seat 9 both smaller than the cross-sectional size of the first through hole 5, it is convenient for storage. And by making the position of the hinge seat 9 always correspond to the position of the connecting seat 4 when the grinding main body 2 and the side grinding block 3 are parallel and perpendicular, it is convenient for angle adjustment.

[0045] As Figure 3 shown, as a preferred embodiment of the present utility model, the sides of the grinding main body 2 and the side grinding block 3 are communicated. When the side grinding block 3 is vertical, the position of the lowermost grinding roller 10 is flush with the position of the grinding roller 10 on the surface of the grinding main body 2.

[0046] In the embodiment of the present utility model, when in use, by making the sides of the grinding main body 2 and the side grinding block 3 communicate, and when the side grinding block 3 is vertical, the position of the lowermost grinding roller 10 is flush with the position of the grinding roller 10 on the surface of the grinding main body 2. Thus, when the side grinding block 3 is vertical, the bottom can be ground, further generating grinding dead corners, making the grinding effect better.

[0047] In the above embodiment of the present utility model, an external wall putty grinding machine is provided. When grinding on a flat wall surface, the hinge block 7 and the hinge seat 9 are pulled out from the first through hole 5 of the connecting seat 4 at the top of the grinding main body 2. At the same time, the sliding groove 8 in the middle of the hinge block 7 moves along the positioning column 6 on the connecting seat 4, so that the side grinding block 3 can move, making it flush with the grinding main body 2, thus increasing the grinding range and further improving the working speed;

[0048] Subsequently, the grinding rollers 10 on the side grinding block 3 and the grinding main body 2 are started to grind the wall surface. And since both the side grinding block 3 and the grinding main body 2 are set to be square, when grinding, the places that are difficult to grind, such as the corners, can be ground, making the grinding effect better;

[0049] When encountering an L-shaped corner or a U-shaped corner, the angle of any one side of the side grinding block 3 can be changed as needed, so that the hinge block 7 and the hinge seat 9 move into the first through hole 5 of the connecting seat 4 at the top of the grinding main body 2. At the same time, the sliding groove 8 in the middle of the hinge block 7 moves along the positioning column 6 on the connecting seat 4, so that the side grinding block 3 is perpendicular to the grinding main body 2, enabling the side to be ground synchronously, thus improving the working efficiency;

[0050] When the side grinding block 3 is parallel or perpendicular to the grinding main body 2, the second fixed insertion block 12 or the first fixed insertion block 11 will be aligned with the positioning block 13. Then, the connecting insertion block 16 is inserted into the insertion hole 14 on the surface of the positioning block 13 and extends into the second through hole 15 on the surface of the second fixed insertion block 12 or the first fixed insertion block 11. At the same time, the movable limiting plate 17 will extend out of the outer end of the second fixed insertion block 12 or the first fixed insertion block 11. Then, under the action of the spring 18, the position of the side grinding block 3 and the grinding main body 2 is fixed, thus avoiding movement during use and affecting the grinding work.

[0051] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
