Since the telescopic mechanism 131 may incline the fixed bracket 122 and the main body 110 during the adjustment of the height of the docking portion 121 relative to the ground, the portable vacuum cleaner 100 may be prevented from falling down by locating the center of mass of the portable vacuum cleaner 100 between the first wheel 151 and the second wheel 152.
The first wheel 151 may be a front wheel, the second wheel 152 may be a rear wheel, and the first wheel 151 and the second wheel 152 have the same outer diameter and substantially parallel rotational axes. The first wheel 151 is rotatably disposed at an end of the rotating bracket 132 away from the mounting bracket 111, and the second wheel 152 is rotatably disposed at a bottom surface of the fixing bracket 122.

The rotating bracket 132 is driven by the telescopic mechanism 131 to rotate along different directions, so that the ground height of the butt joint part 121 can be adjusted, and when the butt joint part 121 is in butt joint with the butt joint structure of other devices, the butt joint part 121 can be accurately butted with the other devices only by adjusting the butt joint part 121 to the ground height which is the same as that of the butt joint structure through the telescopic mechanism 131.
The mobile vacuum cleaner 100 provided by the present application is installed in a docking manner by providing the docking portion 121 and a docking structure of another device, and when the docking portion 121 is not at the same height as the docking structure of the other device, the ground height of the docking portion 121 can be adjusted by the adjusting device 130 so that the docking portion 121 and the docking structure maintain the same height, thereby achieving accurate docking between the docking portion 121 and the docking structure.
Referring to fig. 7, the present embodiment further provides a grinding and dust-collecting apparatus 200, which includes a grinding machine 210 detachably connected to the mobile dust collector 100.
Referring to fig. 7 and 8, in the present embodiment, the grinder 210 includes a base 212 and an extension 213, the extension 213 is connected to the base 212 and disposed toward the docking portion 121, and the extension 213 is provided with a connection hole 2111 to be detachably connected to the docking portion 121.

The aperture size of the connection hole 2111 may be the same as the aperture size of the first hole 1212 and the aperture size of the second hole 1213, or may be different, and may be specifically adjusted according to actual requirements.
When the grinder 210 and the mobile dust collector 100 are installed in a butt joint mode, if the connecting hole 2111 and the butt joint part 121 are located at the same height, the grinder 210 and the mobile dust collector 100 approach each other until the connecting hole 2111 and the butt joint part 121 are aligned, and then the connecting piece is arranged in the connecting hole 2111 and the butt joint part 121 in a penetrating mode to achieve butt joint installation of the grinder 210 and the mobile dust collector 100, manual butt joint is avoided, and labor is saved. If the connection hole 2111 and the docking portion 121 are not at the same height, as shown in fig. 7, the floor where the grinder 210 is located is lower than the floor where the mobile vacuum cleaner 100 is located, and the floor where the grinder 210 is located and the floor where the mobile vacuum cleaner 100 is located have a height difference H, at this time, the height where the docking portion 121 is located is higher than the height where the connection hole 2111 is located, that is, the docking portion 121 and the connection hole 2111 are not at the same level, and there is a certain height distance difference between the docking portion 121 and the connection hole 2111. The rotating bracket 132 can be driven by the telescopic mechanism 131 to rotate in the counterclockwise direction to reduce the ground height of the docking portion 121 until the center of the docking portion 121 and the center of the connection hole 2111 are at the same horizontal height, wherein after the docking portion 121 is adjusted to be at the same height as the connection hole 2111, the grinder 210 and the mobile dust collector 100 approach each other until the connection hole 2111 and the docking portion 121 are aligned, and then the grinder 210 and the mobile dust collector 100 are mounted in a docking manner by penetrating through the connection hole 2111 and the docking portion 121 through a connection member.
In the grinding process of the grinder 210, the mobile dust collector 100 can move synchronously with the grinder 210, and dust generated in the grinding process of the grinder 210 can be quickly absorbed by the mobile dust collector 100, so that the dust is prevented from flying everywhere, and meanwhile, constructors for operating the mobile dust collector 100 are saved, the labor intensity is reduced, and the working efficiency is improved.
Referring to fig. 9, in the present embodiment, the grinder 210 may further include a first rotating wheel 221 and a second rotating wheel 222, the first rotating wheel 221 and the second rotating wheel 222 have the same outer diameter and are coaxially disposed, the first rotating wheel 221 and the second rotating wheel 222 may be disposed side by side on the bottom surface of the base 212, the top of the first rotating wheel 221 and the top of the second rotating wheel 222 are both located on a first tangent plane, the bottom of the first rotating wheel 221 and the bottom of the second rotating wheel 222 are both located on a second tangent plane parallel to and spaced from the first tangent plane, the second tangent plane is used for contacting the ground, and after the mobile vacuum cleaner is connected to the grinder, the first wheel 151 of the mobile vacuum cleaner 100 may be located between the first tangent plane and the second tangent plane or above the first tangent plane, and the first wheel 151 may intersect or be tangent to the first tangent plane, only by ensuring that the first wheel 151 is not in contact with the ground.
The first wheel 151, the first rotating wheel 221 and the second rotating wheel 222 may be located on the same line, and since the tangent planes of the three wheels are located at the same horizontal plane, it is easy to cause over-positioning, so that the first rotating wheel 221 and the second rotating wheel 222 of the grinder 210 cannot effectively contact the ground, and a phenomenon of slipping occurs in the first rotating wheel 221 and the second rotating wheel 222, therefore, after the grinder 210 and the mobile vacuum cleaner 100 are mounted in a butt joint manner, the first wheel 151 may be lifted to a certain height by the telescopic mechanism 131 to ensure that the first wheel 151 does not contact the ground, that is, the first wheel 151 is separated from the second tangent plane contacting the ground to be away from the ground, so that a phenomenon of slipping occurs in the first rotating wheel 221 and the second rotating wheel 222 is avoided, and the first rotating wheel 221 and the second rotating wheel 222 can contact the ground.
When the grinder 210 and the mobile vacuum cleaner 100 need to be separated, the first wheel 151 needs to be lowered to a certain height by the telescopic mechanism 131 until the docking portion 121 of the mobile vacuum cleaner 100 is at the same height as the coupling hole 2111 of the grinder 210. Then, the connection member connected to the docking portion 121 and the connection hole 2111 is pulled out, and the grinder 210 and the mobile cleaner 100 are separated from each other, thereby achieving easy separation and convenient operation.
In summary, the connection hole 2111 of the grinder 210 in the grinding and dust-collecting apparatus 200 provided by the present application is detachably connected to the docking portion 121 of the mobile dust collector 100, so as to facilitate the detachment and installation of the two, and meanwhile, the adjustment device 130 can adjust the docking portion 121 to the same height as the connection hole 2111, and does not need manual docking, so as to achieve precise docking and installation of the two; the grinding and dust-absorbing device 200 integrates grinding and dust-absorbing functions, and avoids a large amount of dust in the grinding process.
