[0029] Example:

[0030] See Figures 1-6 The present embodiment provides a scraping device for the inner and outer corners of walls during construction, mainly comprising a scraping plate 1 and a telescopic handle assembly 2. The two opposite long sides of the scraping plate 1 are parallel to each other so as to adapt to the scraping of the straight part of the wall. One end of the scraping plate 1 in its length direction is constructed as a convex vertical corner for scraping the inner inner corner of the wall, and the other end is constructed as a concave vertical corner for scraping the outer corner of the wall.

[0031] The above structural design of the scraping plate 1 in this embodiment enables the device to adapt to different types of wall corners, whether it is a wall internal corner or a wall external corner, and can achieve effective scraping, thereby improving the versatility and applicability of the device.

[0032] In this embodiment, a T-shaped handle 3 is installed in the middle of the top surface of the scraper plate 1, which can provide a stable grip for the operator to easily control the movement and direction of the scraper plate 1. The center of the upper end of the T-shaped handle 3 away from the scraper plate 1 is connected to the telescopic handle assembly 2.

[0033] Specifically, the telescopic handle assembly 2 includes an L-shaped rod 4, a connecting rod 5 and an extension rod 6. One end of the L-shaped rod 4 is detachably connected to the T-shaped handle 3 for easy disassembly and assembly, and the other end is detachably connected to the connecting rod 5 at an obtuse angle; the end of the connecting rod 5 away from the L-shaped rod 4 is movably inserted into the extension rod 6, and the extension rod 6 can be telescoped within the connecting rod 5, and the extension rod 6 and the connecting rod 5 are detachably connected.

[0034] The design of the telescopic handle assembly 2 in this embodiment allows the operator to quickly adjust the handle length according to the wall height, providing greater operational flexibility. When scraping higher walls, the operator can adjust the length of the telescopic handle assembly 2 without having to frequently move a ladder or other auxiliary equipment. When scraping lower walls, the operator can detach the telescopic handle assembly 2 from the scraper plate 1 and directly grasp the T-shaped handle to scrape the scraper plate 1, significantly improving construction speed.

[0035] Furthermore, since the telescopic handle assembly 2 adopts a detachable design, the device of the present invention can be conveniently stored, stored and transported when not in use, saving space and facilitating the repair and replacement of individual components.

[0036] In a further specific embodiment, in order to facilitate the replacement of the damaged scraping plate 1, as shown in FIG. Figure 3 、 Figure 5 As shown, a mounting column 7 perpendicular to the plate surface is fixed at the center of the top surface of the scraper plate 1, and a mounting groove 8 is provided at the lower end of the lower vertical rod of the T-shaped handle 3, which can be adapted to be mounted on the outside of the mounting column 7; a through-hole 9 is constructed on the mounting column 7, and a docking hole 10 corresponding to the through-hole 9 is constructed on the mounting groove 8. A screw 11 passes through the docking hole 10 and the through-hole 9 and is locked by the corresponding nut 12 to realize the connection between the T-shaped handle 3 and the scraper plate 1.

[0037] Furthermore, in order to ensure the connection effect, the installation column 7 is penetrated by two sets of upper and lower through holes 9, and the central axes of the two sets of through holes 9 are perpendicular to each other, and the installation groove 8 is penetrated by two sets of upper and lower docking holes 10 corresponding to the two sets of through holes 9.

[0038] During operation, the mounting column 7 is inserted into the mounting groove 8, and the two sets of docking holes 10 are respectively aligned with the two ends of the corresponding through-holes 9. Then, the screw 11 is inserted through the two sets of docking holes 10 and the through-holes 9. Finally, the nut 12 is put on the screw 11 and locked. Then, the mounting column 7 and the T-shaped handle can be tightly connected, thereby fixing the scraper plate 1.

[0039] In a further specific embodiment, Figure 3 、 Figure 5 、 Figure 6 As shown, a slot 13 is defined at the center of the top of the upper end of the T-shaped handle 3. An insert 14 is fixed to the end of the L-shaped rod 4, which is adapted to be inserted into slot 13. A screw 15 is inserted into the outer thread of slot 13, which can be inserted into the groove. Insert 14 has a fixing hole 16, and screw 15 can be rotated and inserted into fixing hole 16 to connect the L-shaped rod 4 to the T-shaped handle 3. The L-shaped rod 4 and the T-shaped handle 3 can be separated by unscrewing screw 15 from fixing hole 16.

[0040] Furthermore, slot 13 has a square cross-section along the extension of the scraper plate, as does the insert block 14. Four fixing holes 16 are located on the four circumferential sides of the insert block. This arrangement offers the advantage of varying the angle at which the insert block 14 is inserted into slot 13, changing the orientation of the connection between the telescopic handle assembly 2 and the scraper plate 1, thereby achieving smoothing of different areas of the wall.

[0041] In a further embodiment, the end of the L-shaped rod 4 is provided with a snap-in interface for inserting and locking the end of the connecting rod 5. Moreover, after the connecting rod 5 is installed, the obtuse angle formed by the right angle on the L-shaped rod 4 and the connection point of the connecting rod 5 is a same-side internal angle.

[0042] In a further specific embodiment, Figure 1 、 Figure 2 、 Figure 4 As shown, a second slot 17 is provided on the side of the connecting rod 5 away from the L-shaped rod 4, and the extension rod 6 is movably inserted into the second slot 17. The outer thread of the second slot 17 is inserted with a second screw 18 that can extend into the slot. The extension rod 6 is provided with a number of positioning holes 19 distributed in an array along its length direction. The second screw 18 can be inserted into the corresponding positioning hole 19 by rotation, thereby realizing the connection between the connecting rod 5 and the extension rod 6.

[0043] When using this device, the operator holds one end of the connecting rod 5. Because the distance between the connecting rod 5 and the scraper plate 1 is relatively large, this prevents putty from falling on the operator when scraping the wall. The extension rod 6 is movably inserted into the other end of the connecting rod 5. Depending on the wall height or the operator's needs, the operator can rotate screw 2 18 on the connecting rod 5 so that screw 2 18 contacts the positioning hole 19 of the extension rod 6, securing the extension rod 6 to the connecting rod 5. This telescopic handle design allows for quick length adjustment to accommodate walls of varying heights and the needs of different operators.

[0044] In this embodiment, by allowing the second screw 18 to extend into the positioning hole 19 of the extension rod 6, the fixing effect of the extension rod 6 and the connecting rod 5 can be effectively ensured, so that the device is more stable when scraping the wall and the scraping effect is better.

[0045] like Figure 1 、 Figure 6 As shown, a handle 20 is fixed to the outside of the end of the extension rod 6 away from the connecting rod 5. The outer periphery of the handle 20 is constructed with anti-slip grooves. The anti-slip design ensures that the handle 20 maintains a stable grip even in wet or sweaty conditions, adapting to various working environments and reducing construction errors caused by hand slippage.

[0046] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Reference can be made to the common and similar parts between the various embodiments. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the method description.

[0047] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
