An opening 402 that is engaged with the card slot 102 is provided at the center of the bottom end of the shell 401, and a connecting pipe 405 that is connected to the dust removal connecting pipe 12 is provided at the side end of the shell 401.

[0030] The upper end seat 3 includes a hinged seat 302 arranged at the side end of the end seat body 301, and a plug plate 303 is hinged on the hinged seat 302. The connecting seat 2 5 includes a seat body 501, and a socket 502 corresponding to the position of the hinged seat 302 is provided at the side end of the seat body 501. The socket 502 is plugged into the plug plate 303. The locking bolt 6 includes a bolt body 601 that passes through the connecting seat 404 and the end seat body 301. A limit seat 602 is provided on the bolt body 601, and the bottom end is threadedly plugged into the seat body 501.

[0031] The base body 501 is provided with an arcuate end surface 503 near one end surface of the polishing cylinder 1101, and the polishing cylinder 1101 is located in the arcuate end surface 503. A cavity 504 is provided in the base body 501, and a plurality of air inlet holes 505 are provided on the arcuate end surface 503.

[0032] When grinding a flat wall, the drive motor 8 is started, and the drive motor 8 drives the arc-shaped grinding piece 11 to rotate through the lower end 10, and at the same time drives the lock head 1 to rotate through the transmission gear 903 and the driven gear 103, thereby rotating the flat grinding end 2;

[0033] Hold the handle 1202 of the dust removal connecting tube 12, bring the plane grinding end 2 into contact with the plane wall, and then start grinding the plane wall.

[0034] When it is necessary to grind a curved wall, there is no need to switch additional equipment. The curved grinding piece 11 can be directly brought into contact with the curved wall. The hexagonal ends 1102 at both ends of the grinding column 1101 of the curved grinding piece 11 are respectively inserted into the hexagonal hole 1 902 of the upper end 9 and the hexagonal hole 2 1002 of the lower end 10 to ensure a stable connection. Driven by the driving motor 8, the curved grinding piece 11 rotates to grind the curved wall. The grinding column 1101 is located in the curved end surface 503, which can play a certain limiting and guiding role on the grinding column 1101, so that the grinding fits the curved wall more closely and ensures the grinding effect.

[0035] During the grinding process, the dust generated is sucked into the dust removal housing 4, enters the connecting pipe 1 1201 of the dust removal connecting pipe 12 through the connecting pipe 405, and is then discharged to the dust removal equipment through the handle 1202 and the connecting pipe 2 1203, thereby achieving the dust removal effect and reducing dust pollution.

[0036] When the arc-shaped grinding piece 11 needs to be replaced, the bolt body 601 is rotated to disengage the bottom end from the seat body 501 by thread. During the process, the insert plate 303 moves upward relative to the socket 502. After it is in place, the upper end head 9 is disengaged from the arc-shaped grinding piece 11. At this time, rotating the upper end seat 3 can eliminate the constraint on the top of the arc-shaped grinding piece 11 and disengage the arc-shaped grinding piece 11 from the lower end head 10. At this time, the arc-shaped grinding piece 11 can be manually removed and replaced. After that, the upper end seat 3 is reversed and the locking bolt 6 is passed through the connecting seat 404 and the end seat body 301. The bottom end of the bolt body 601 is threadedly plugged into the seat body 501 and further locked to ensure a firm connection.

[0037] In the embodiment, during the specific implementation of the grinding work, in order to reduce the load of the present invention, the arc-shaped grinding piece 11 can also be removed and replaced with a transmission shaft when grinding a flat wall. A hexagonal end 1102 is provided at both ends of the transmission shaft. Similarly, when grinding a curved wall, the flat grinding end 2 can be removed from the lock head 1.

[0038] When the wall surface grinding device for construction projects is implemented, when grinding a flat wall, the drive motor 8 is started, which drives the arc-shaped grinding piece 11 to rotate through the lower end 10, and at the same time drives the lock head 1 to rotate through the transmission gear 903 and the driven gear 103, so that the flat grinding end 2 rotates. The handle 1202 of the dust removal connecting pipe 12 is held and the flat grinding end 2 is brought into contact with the wall to start the operation. When grinding a curved wall, there is no need to switch equipment, and the arc-shaped grinding piece 11 is directly brought into contact with the wall surface. The hexagonal end heads 1102 at both ends are respectively inserted into the inner hexagonal hole 1 902 of the upper end 9 and the inner hexagonal hole 2 1002 of the lower end 10. Under the drive of the drive motor 8, the grinding is rotated and the arc end face 503 can limit and guide the grinding column 1101. The dust generated by grinding is sucked into the dust removal housing 4 and discharged to the dust removal equipment through the connecting pipe 405, the connecting pipe 1 1201 of the dust removal connecting pipe 12, the handle 1202 and the connecting pipe 2 1203.

[0039] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without creatively designing a structure and embodiment similar to the technical solution, they shall fall within the scope of protection of the present invention.
