[0028] The working principle of a sanding machine with protective function provided by the utility model is as follows:

[0029] The first step: during use, when the rotating plate 3 is placed horizontally, the tension of the tension spring 9 and the block at the front end of the fixed plate 2 can keep the rotating plate 3 in a horizontal state. At this time, the protective plate 4 can protect the operating workers to prevent debris from hurting people. Similarly, when the rotating plate 3 is upright, the tension spring 9 and the block at the upper end of the fixed plate 2 can keep the rotating plate 3 upright. At this time, the protective plate 4 placed on top will not affect the loading.

[0030] Step 2: The screw rod 12 can be rotated by turning the hand wheel 13. The screw rod 12 rotates and moves along the base 10. At this time, the first extrusion block 14 moves synchronously. The first extrusion block 14 moves backward to squeeze the slider 18. The slider 18 is squeezed and slides downward along the groove. At this time, the universal wheel 20 moves downward and can contact the ground. After the universal wheel 20 contacts the ground, it can facilitate moving the equipment. When the first extrusion block 14 is reset, the slider 18 can be reset by itself due to the elastic force of the first spring 21.

[0031] Compared with the related art, the sanding machine with protective function provided by the utility model has the following beneficial effects:

[0032] When the rotating plate 3 is placed horizontally, the pulling force of the tension spring 9 and the block at the front end of the fixed plate 2 can keep the rotating plate 3 in a horizontal state. At this time, the protective plate 4 can protect the operating workers and prevent debris from injuring people. Similarly, when the rotating plate 3 is erected, the rotating plate 3 can be kept upright by the tension spring 9 and the block at the upper end of the fixed plate 2. At this time, the protective plate 4 is placed on top and will not affect the loading. This mechanism can prevent debris from flying out and injuring people, which is very beneficial to safe production. The screw rod 12 can be rotated by rotating the hand wheel 13, and the screw rod 12 rotates and moves along the base 10. At this time, the first extrusion block 14 moves synchronously. The first extrusion block 14 moves backward to squeeze the slider 18. The slider 18 is squeezed and slides downward along the groove where it is located. At this time, the universal wheel 20 moves downward to contact the ground. After the universal wheel 20 contacts the ground, it is beneficial to move the equipment. When the first extrusion block 14 is reset, the slider 18 is reset by the elastic force of the first spring 21. This mechanism is very convenient for moving the equipment.
