As shown in fig. 2, the present invention further includes a fixing mechanism for fixing the fixing section 5, the fixing mechanism includes a fixing hole formed on the supporting column 9 in fig. 1, and the free end of the backing plate 7 is welded with a fixing pin 6 capable of being inserted into the fixing hole. When the pulley 8 passes through the lifting hole and moves to the lower part of the fixed section 5, namely, in the state shown in fig. 1, the fixed section 5 can be fixed by inserting the fixing pin 6 into the fixing hole on the supporting column 9.

As shown in figure 2, the movable section is composed of a plurality of slide bars 12 which are mutually connected in a sliding way, when the movable section is not used, the slide bars 12 are contracted together, and when the movable section is used, the slide bars 12 can be pulled out to increase the length of the guide rail. Specifically, the fixed section 5 and the movable section both adopt guide rails with U-shaped cross sections, and the slide bars 12 on the right side are gradually reduced in width and are sequentially connected in the slide bars 12 on the left side in a sliding manner. In order to make the sliding surfaces of all the slide bars 12 flush with each other after the slide bars 12 are pulled out so that the pulleys 8 move, the opposite ends of two adjacent slide bars 12 in the embodiment are provided with a flush mechanism which is matched with each other to make the sliding surfaces of the two slide bars 12 flush.

When the connecting rod moves to the connecting hole 14, the two sliding rods 12 can be connected by pushing the connecting rod into the connecting hole 14 through the spring.

The specific implementation process is as follows:

when the invention is not used, the movable section is contracted in the fixed section 5, namely the state shown in figure 1, thus reducing the volume of the invention and being convenient for placing and carrying. In addition, when the invention is not used, the pulley 8 is positioned below the fixed section 5, the backing plate 7 rotates to the position below the fixed section 5 under the extrusion action of the pulley 8, and the fixing pin 6 on the backing plate 7 is inserted into the fixing hole on the supporting column 9. Therefore, the guide rail is fixed below the base 10, the guide rail is stored, and the guide rail is convenient to carry.

When the wall polishing device is used for polishing a wall, the fixing pin 6 on the backing plate 7 is pulled out of the fixing hole on the supporting column 9 manually, and the backing plate 7 is released. The fixed section 5 is then pulled downwardly so that the fixed section 5 moves below the pulley 8 and abuts the ground, with the pulley 8 attached to the fixed section 5. Because the pin joint of backing plate 7 is connected with the torsional spring, backing plate 7 is released the back, and the torsional spring can drive backing plate 7 upwards to rotate in order to seal the lift hole, pastes after subaerial when canned paragraph 5, backing plate 7 can't rotate downwards, so the lift hole can not influence pulley 8 and normally slide on canned paragraph 5.

After the pulley 8 is connected to the fixed section 5, the present invention is manually aligned to make the side of the base 10 closely contact with the wall, and then the sliding rod 12 is pulled out to form a finished fixed section 5 to guide the pulley 8 to move. After the fixed section 5 is pulled out, the dust collector 4, the motor and the telescopic rod 3 can be opened, the polishing disc is attached to the wall, and the motor drives the polishing disc to rotate to polish the wall. The 3 lifts of in-process manual control electric telescopic handle of polishing realize the vertical polishing of wall, grips simultaneously pushing hands 11 and promotes base 10 along the horizontal slip of canned paragraph 5 and realize the horizontal polishing of wall.

The manual direct pushing device moves in the prior art, and the fixed section 5 is not guided, so that the device is extremely easy to deviate in the pushing process due to the manual operation problem, the pressure of the polishing disc on the wall is changed, the polishing force of the wall is changed, and the wall polishing degree is uneven. According to the invention, the fixing section 5 is arranged to guide the base 10 to move, so that the deviation in the moving process of the device can be greatly avoided, and the polishing uniformity of the wall is improved.

After polishing, the sliding rod 12 is retracted, the fixing section 5 is manually lifted, so that the pulley 8 pushes the backing plate 7 to rotate downwards again, and then the backing plate passes through the lifting hole, so that the pulley 8 is located below the fixing section 5, and the state shown in fig. 1 is recovered. Then the fixing pin 6 on the backing plate 7 is manually inserted into the fixing hole to fix the fixing section 5, and the pushing handle 11 can be held to push the mobile fixing device to move, so that the mobile fixing device is convenient to carry. Compared with the method that the fixed section 5 and the base 10 are separately arranged, and the base 10 is lifted on site to assemble the fixed section 5 on the base 10 when in use, the installation of the fixed section 5 is more convenient.

Example two

As shown in fig. 4, the difference between the first embodiment and the second embodiment is that the movable section is hinged at the right end of the fixed section 5, and the movable section can be folded outwards to be attached to the outer side surface of the fixed section 5. When the portable folding chair is not used, the movable section is folded to be attached to the outer side face of the fixed section 5, the size of the portable folding chair can be reduced, and the portable folding chair is convenient to place and carry. When in use, the movable section is turned over and is connected with the fixed section 5 horizontally to form a complete guide rail for the sliding of the pulley 8.

In order to increase the fixing stability of the movable section, the free end of the movable section is provided with a first magnet in the embodiment, and the fixed section 5 is provided with a second magnet 17 for adsorbing the first magnet. The first magnet and the second magnet 17 are attracted to each other to improve the fixing stability of the movable section. Of course, the movable segment can also be fixed on the fixed segment 5 by a lock catch.

EXAMPLE III

As shown in fig. 5, the present embodiment is different from the first embodiment in that two ends of one side surface of the base 10 are horizontally installed with the calibration rod 19, and the calibration rod 19 is perpendicular to the side surface of the base 10. The calibration rod 19 adopts the existing telescopic rod 3, and scales are carved on the calibration rod 19. In practical use, the calibration rod 19 can be pulled out to abut against the wall, and the base 10 can be parallel to the wall by making the two calibration rods 19 extend to the same length, thereby realizing the calibration of the position of the base 10. This embodiment is suitable for the case that a certain distance is required between the base 10 and the wall, and the base 10 cannot be tightly attached to the wall to achieve calibration.

The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
