As shown in fig. 1 to 5, the present embodiment is substantially the same as embodiment 1, and preferably, the abutting plate assembly includes a displacement preventing plate 47, an extension bar 50 and an abutting plate 53, a first cross bar 48 is horizontally and fixedly installed on one side of the displacement preventing plate 47, a sleeve 49 and a second sleeve 52 are respectively and fixedly connected to one ends of the first cross bar 48 and the extension bar 50, a supporting leg 51 is disposed on a bottom side of the extension bar 50, a ball seat 54 is fixedly connected to one side of the abutting plate 53, a spherical rotating groove is formed on one side of the ball seat 54 and a rotating ball 55 is rotatably installed, one side of the rotating ball 55 extends to the outside of the ball seat 54 and is fixedly connected to a second threaded pipe 56, and a threaded cavity is formed on one end of the second threaded pipe 56 and is threadedly connected to a threaded rod 57.

In this embodiment, when treating to grind the relative wall of flat wall and treating to grind the flat wall and be unparallel, the rolling ball 55 can be at spherical rotor bowl internal rotation to make to support wallboard 53 can paste mutually with the relative wall of waiting to grind the flat wall, through split type design, make the device can portable and approach.

Example four

As shown in fig. 1 to 5, this embodiment is substantially the same as embodiment 1, and preferably, a side vertical plate 41 is fixedly connected to a vertical side of the vehicle panel 1, a reinforcing rib is disposed between the side vertical plate 41 and the vehicle panel 1, and a plurality of contact rollers 42 are mounted on the vertical side of the vehicle panel 1.

In this embodiment, the strengthening rib has strengthened structural rigidity, and the friction loss has greatly been reduced in setting up of contact roller 42, and people are more laborsaving when using.

EXAMPLE five

As shown in fig. 1 to 5, in this embodiment, basically the same as that of embodiment 1, preferably, a dust collector 44 is mounted on the top side of the vehicle board 1, an external connection pipe 45 is mounted on the dust collector 44, a clamp 46 is disposed on one side of the linkage 28, and a pipe body of one end of the external connection pipe 45 is clamped in the clamp 46.

In this embodiment, the external connection pipe 45 of the vacuum cleaner 44 is fixed by the clamp 46, and dust generated during grinding is collected.

EXAMPLE six

As shown in fig. 1 to 5, this embodiment is substantially the same as embodiment 1, and preferably, a plurality of push rods 11 arranged in a ring shape at equal intervals are fixedly connected to the top edge position of the rotary disk 10.

In this embodiment, the rotation of the turntable 10 is facilitated for people.

EXAMPLE seven

As shown in fig. 1-5, this embodiment is substantially the same as embodiment 1, and preferably, a third spring 37 is located between the side ring 14 and the sliding plate 35 and sleeved outside the rod body of the second extension rod 36.

In this embodiment, it is more stable when flexible.

Example eight

As shown in fig. 1 to 5, this embodiment is substantially the same as embodiment 1, and preferably, a limit plate 18 is fixedly connected to one end of the swing rail 17.

In this embodiment, the sliding sleeve 19 is prevented from falling from the outside of the swing rail 17.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
