By clamping one side of the door and window in the clamping block 6 through the clamping plate 7, and the other side of the door and window in the clamping block 8 through the clamping plate 9, the two adjacent sides of the door and window are clamped, so that the position of the door and window can be fixed, and it is equivalent to clamping only one corner of the door and window. Therefore, the size of the support 1 can be smaller than the size of the door and window. Compared with the device for clamping both sides of the door and window, the device does not require a larger size and occupies a small area. Due to the arrangement of the two sliding blocks 3, it is convenient to replace the different corner clamps of the door and window, and the relative positions of the door and window and the polishing machine 13 can be adjusted by adjusting the positions of the sliding block 3, the clamping block 6 and the polishing machine 13, so that it is convenient to grind and polish multiple welding points on the door and window.

[0019] In one embodiment of the present application, preferably, a first screw 14 and a second screw 15 are threadedly connected on one side of the support 1, one end of the first screw 14 extends into the corresponding limit groove and is rotatably connected to the corresponding slider 3, and no thread is set at the rotational connection between the first screw 14 and the slider 3, one end of the second screw 15 extends into the positioning groove and is rotatably connected to the moving block 4, and no thread is set at the rotational connection between the second screw 15 and the moving block 4, and the position of the slider 3 in the corresponding limit groove can be adjusted by rotating the first screw 14, and the position of the moving block 4 in the positioning groove can be adjusted by rotating the second screw 15.

[0020] In one embodiment of the present application, preferably, a first bolt 16 is threadedly connected to the top of the clamping block 8, one end of the first bolt 16 is rotatably connected to the clamping plate 9, and no thread is set at the rotational connection between the first bolt 16 and the clamping plate 9, and a second bolt 17 is threadedly connected to the top of the clamping block 6, one end of the second bolt 17 is rotatably connected to the clamping plate 7, and no thread is set at the rotational connection between the second bolt 17 and the clamping plate 7, rotating the first bolt 16 can drive the clamping plate 9 to clamp the doors and windows, and rotating the second bolt 17 can drive the clamping plate 7 to clamp the doors and windows.

[0021] In one embodiment of the present application, preferably, the inner bottom wall of the groove and the inner bottom wall of the opening groove are at the same height as the upper surface of the support 1, so that the upper surface of the support 1 can also support the doors and windows.
