[0043] When people need to use the device, they can start the vacuum cleaner 83, which will extract the air inside the first dust suction pipe 84 and the second dust suction pipe 85. When the fourth connecting rod 75 moves downward, it will contact the blocking rod 86, thereby squeezing the blocking rod 86 to move downward, and the fifth spring 87 is compressed, so that the blocking rod 86 no longer blocks the lower part of the first dust suction pipe 84 and the second dust suction pipe 85, so that the dust inside the housing 1 can enter the vacuum cleaner 83 through the first dust suction pipe 84 and the second dust suction pipe 85, and then the dust will The dust collecting frame 82 is moved forward and the dust collecting frame 82 is moved back to the collecting frame 82. When the fourth connecting rod 75 moves upward and resets, it will separate from the blocking rod 86, and the fifth spring 87 returns to its original state, driving the blocking rod 86 to move upward and reset, so that the blocking rod 86 blocks the lower part of the first dust suction tube 84 and the second dust suction tube 85 again, and so on. When people do not need to use the device, they turn off the vacuum cleaner 83, then pull the handle forward to drive the collecting frame 82 to move forward, and then dispose of the dust in the collecting frame 82, and finally put the collecting frame 82 back to its original position.

[0045] When people need to put the inner gear into the middle of the inner bottom of the outer shell 1, first put the inner gear in front of the support block 92, and then push the inner gear backward. When the inner gear contacts the support block 92, it will squeeze the support block 92 to move slightly backward, and the sixth spring 93 will be compressed. At this time, people will feel a certain resistance, and then release the inner gear. The sixth spring 93 returns to its original state, driving the support block 92 to move forward and reset, pushing the inner gear forward slightly, so that the inner gear can be located directly below the grinding disc 4, which has a positioning effect.

[0047] When the grinding disc 4 is working, it is likely to cause a slight vibration of the entire device. At this time, the block 102 blocks the front side of the collection frame 82 to prevent the collection frame 82 from sliding forward. When people need to take out the collection frame 82, they first pull the pull rod 101 upwards, and the seventh spring 103 stretches, driving the block 102 to move upwards, so that the block 102 no longer blocks the front side of the collection frame 82, and then the collection frame 82 can be taken out, and then the pull rod 101 is released, and the seventh spring 103 is pulled out. 03 returns to its original state, driving the pull rod 101 and the block 102 to move downward and reset, then the dust in the collection frame 82 can be disposed of, and then the collection frame 82 is put back to its original position. When the collection frame 82 contacts the block 102, the block 102 is squeezed to move upward, and the seventh spring 103 is stretched. When the collection frame 82 passes over the block 102, the seventh spring 103 returns to its original state, driving the block 102 to move downward and reset, so that the block 102 blocks the front side of the collection frame 82 again.
