[0019] See also Figure 1-Figure 3 The utility model provides a technical solution: a stair scraper for decoration and renovation, comprising a first scraper 1, a second scraper 11 is horizontally arranged above one side of the first scraper 1, and a scraper 13 is arranged on the bottom sides of the first scraper 1 and the second scraper 11; a first adjusting mechanism: a slide groove 2 is vertically opened inside the upper end of the first scraper 1, and a slide bar 21 is slidably connected to the inner wall of the slide groove 2, and a connecting block 22 is symmetrically installed at the front and rear ends of one side of the slide bar 21, and the slide bar 21 is fixedly connected to the front and rear ends of one side of the second scraper 11 through two groups of connecting blocks 22. The inner wall of one side of the slide groove 2 is vertically penetrated by two groups of connecting grooves 23, and the connecting block 22 is slidably connected to the connecting groove 23. A second screw rod 24 is passed through and spirally connected to the middle part of the slide bar 21, and the second screw rod 24 is rotatably connected to the first scraper 1 through a bearing. The second screw rod 24 is arranged on one end of the outer side of the first scraper 1 and is fixedly installed with a second knob 25.

[0020] In this technical solution, by turning the second knob 25, the slide bar 21 can be driven to move up and down in the slide groove 2 through the second screw rod 24, and the second scraper 11 can be driven to move up and down on the outside of the first scraper 1 through the connecting block 22. The use height of the second scraper 11 can be adjusted according to the height of the stair steps, so that the scraping strips 13 on the bottom sides of the first scraper 1 and the second scraper 11 fit with the surface of the stair steps, and further, the scraping operation can be performed on two steps of the stair at the same time, which has high work efficiency.

[0021] In this embodiment, the second adjustment mechanism is used to adjust the use position of the scraper 13. The second adjustment mechanism includes a first screw rod 15. The bottom sides of the first scraper 1 and the second scraper 11 are evenly provided with mounting grooves 12. The scraper 13 is slidingly connected to the mounting groove 12. The end of the scraper 13 placed on the inner side of the mounting groove 12 is vertically provided with a threaded groove 14. The first screw rod 15 is spirally connected to the threaded groove 14. The first screw rod 15 is rotatably connected to the mounting groove 12 through a bearing. The top of the second screw rod 24 is fixedly provided with a first knob 16.

[0022] In this technical solution, rotating the first knob 16 can drive the first screw rod 15 to rotate. The first screw rod 15 is spirally connected to the threaded groove 14. During the rotation of the first screw rod 15, the scraper 13 can be driven to move up and down in the mounting groove 12. When the scraper bar 13 moves upward and is retracted into the mounting groove 12, the spacing between two adjacent groups of scraper grooves can be adjusted.

[0023] In this embodiment, the first scraper 1 is in an inverted L-shape, the scraper strip 13 is T-shaped, the scraper strip 13 matches the size of the mounting groove 12, and a handle 26 is fixedly installed on the upper inner side of the first scraper 1, and the outer side of the handle 26 is provided with anti-slip grooves.

[0024] In this technical solution, the first scraper 1 is in an inverted L shape, and the upper end of the first scraper 1 can be attached to the side of the stair step, so as to position the first scraper 1. The handle 26 can be used to push the first scraper 1 and the second scraper 11 to move on the stair step to perform the scraping operation.

[0025] When a stair scraper for decoration is used, rotating the first knob 16 can drive the first screw rod 15 to rotate. The first screw rod 15 is spirally connected to the threaded groove 14. During the rotation of the first screw rod 15, the scraper bar 13 can be driven to move up and down in the installation groove 12. When the scraper bar 13 moves upward and is stored in the installation groove 12, the distance between the two adjacent scraper grooves can be adjusted. Rotating the second knob 25 can drive the slide bar 21 to move up and down in the slide groove 2 through the second screw rod 24. The second scraper 11 can be driven to move up and down on the outside of the first scraper 1 through the connecting block 22.
