[0043] In this embodiment, the shielding shell 2, the cover plate 3 and the movable cover 7 are designed so that the grinding wheel 6 can be completely wrapped without dead angles, and the grinding wheel 6 will not be exposed when not in use;

[0044] Among them, in order to achieve the purpose of replacement, the present device adopts the following technical solutions: the cover plate 3 is connected to the shielding shell 2 by bolts, an arc groove 15 is provided on the inner wall of one side of the movable cover 7, a baffle 16 is provided on the outer fixed sleeve of the transmission shaft 5, the baffle 16 is in contact with one side of the grinding wheel 6, a baffle 2 17 is provided on the other side of the grinding wheel 6, the baffle 2 17 is connected to the transmission shaft 5 by bolts, the cover plate 3 is connected to the shielding shell 2 by bolts, and the baffle 2 17 is also connected to the transmission shaft 5 by bolts, so that when the grinding wheel 6 is worn out, the cover plate 3 can be disassembled, and then the baffle 2 17 can be disassembled, so that the grinding wheel 6 can be easily replaced, and the design of the arc groove 15 can prevent the bolts from blocking the movable cover 7 when the movable cover 7 rotates and making it unable to rotate;

[0045] Among them, in order to achieve the purpose of preventing the prism 13 from rotating at will, the present device adopts the following technical solutions: a fixed block 18 is fixedly connected to the other side of the shielding shell 2, a prism groove is provided inside the fixed block 18, the other end of the prism 13 is embedded in the prism groove and slidably connected thereto, a magnet 19 is fixedly connected to the other side of the shielding shell 2, the magnet 19 is located inside the prism groove, a magnet 20 is provided on one side of the magnet 19, the magnet 20 is fixedly connected to the other end of the prism 13, the prism 13 is embedded in the prism groove to prevent the prism 13 from rotating at will, and the design of the magnet 19 and the magnet 20 can prevent the prism 13 from moving out of the prism groove at will;

[0048] In order to achieve the purpose of limiting, the device adopts the following technical solution: a blocking bar 23 is fixedly connected to the bottom of the shielding shell 2, and the blocking bar 23 contacts the movable cover 7. When the movable cover 7 contacts the blocking bar 23, it means that the movable cover 7 completely blocks the through slots 1 and 2.

[0049] Among them, in order to achieve the purpose of reducing wear, the device is implemented by the following technical solutions: the transmission shaft 5 is connected to the bracket 1 and the shielding shell 2 through bearings, the rotating shaft 12 is connected to the bracket 1 through bearings, and the sleeve 8 is connected to the cylinder 4 through bearings. The bearing connection can reduce wear.

[0050] The use process of the utility model is as follows: when grinding work is required, the device can be installed on the grinding machine by using bolts through the design of the mounting hole 22, and the flange 21 on the transmission shaft 5 is aligned with the flange 21 of the power output shaft of the grinding machine, and then the two flanges 21 are connected together by bolts, such as Figure 8As shown, the knob 14 is then pulled to the left, so that the prism 13 can be moved out of the rib groove, and the magnet 2 20 is separated from the magnet 1 19. Then, the knob 14 is turned to rotate the prism 13 and the shaft 1 12. The rotation of the shaft 12 drives the gear 2 11 to rotate. The rotation of the gear 2 11 drives the gear 10 and the sleeve 8 to rotate. Then, under the action of multiple connecting rods 9, the movable cover 7 can be rotated, so that the blocking of the through grooves 1 and 2 by the movable cover 7 can be released, and the grinding wheel 6 can be exposed. After the blocking is released, the knob 14 is pushed back to make the prism 13 stuck in the rib groove again. At the same time, the magnet 19 and the magnet 2 20 are attracted together. Then, the grinding machine is controlled to work to rotate the transmission shaft 5 and the grinding wheel 6. Then, the object to be polished is brought close to the grinding wheel 6 for polishing. Since the magnet 19 and the magnet 2 20 are attracted together, the prism 13 can be prevented from being moved out of the rib groove at will, thereby preventing the movable cover 7 from rotating at will.

[0051] After use, the knob 14 is reversed according to the same principle, so that the movable cover 7 can be reversed, so that the through slots 1 and 2 can be blocked. In cooperation with the blocking shell 2 and the cover plate 3, the grinding wheel 6 can be completely wrapped without dead angles. When not in use, the grinding wheel 6 will not be exposed to the outside. In this way, the device can prevent the grinding wheel 6 from being hit when not in use, and the anti-impact effect is better.

[0052] The above are only preferred embodiments of the present invention. Any person skilled in the art may modify the present invention or modify it into an equivalent technical solution by using the above technical solution. Therefore, any simple modification or equivalent replacement based on the technical solution of the present invention shall fall within the scope of protection claimed by the present invention.
