[0038] It should be noted that, in the description of the utility model, unless otherwise explicitly specified and limited, the terms "providing", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood through specific circumstances.

[0039] The technical solutions of the utility model will be further described below in combination with the drawings and through specific embodiments.

[0040] As shown in the drawings, Figures 1 to 8 The present embodiment provides an angle-adjustable batch scraping tool, which can batch scrape walls at any angle, expands the application range of the batch scraping tool, and is convenient and fast to operate during adjustment without the need to disassemble any parts.

[0041] See Figure 1 The adjustable-angle scraping tool includes a handle 1, a scraping assembly 2, an adjusting assembly 3, and a connecting assembly 4. The scraping assembly 2 includes a rotating connector 21 and two scrapers 22, which are arranged side by side and rotatably connected by the rotating connector 21. The adjusting assembly 3 includes components along its length direction (…). Figure 1 The first adjusting member 31 and the second adjusting member 32 are threaded or slidably connected in the X direction. The overlap length of the first adjusting member 31 and the second adjusting member 32 is adjustable. The first adjusting member 31 is connected to the handle 1, and the second adjusting member 32 is connected to the rotating connecting member 21. The connecting assembly 4 includes a connecting rod 41 corresponding to the two scrapers 22. One end of the connecting rod 41 is rotatably connected to the handle 1, and the other end is rotatably connected to the corresponding scraper 22.

[0042] The adjustable-angle scraping tool provided in this embodiment can adjust the distance between the rotating connector 21 and the handle 1 by adjusting the overlap length of the first adjusting member 31 and the second adjusting member 32. The rotating connector 21 drives the two scrapers 22 to move. The scrapers 22 are also connected to the handle 1 by a connecting rod 41 with a fixed length. Therefore, when the scrapers 22 move under the drive of the rotating connector 21, the movement of the end of the scraper 22 connected to the connecting rod 41 is less than the movement of the end of the scraper 22 connected to the rotating connector 21, thereby causing the scrapers 22 to rotate and the included angle between the two scrapers 22 to change. Thus, the scraping tool can scrape walls with different angles. The first adjusting member 31 and the second adjusting member 32 are threaded or slidably connected, so that the overlap length of the first adjusting member 31 and the second adjusting member 32 can be arbitrarily adjusted. Therefore, the range of rotation angles of the scrapers 22 is large, and the range of the included angle between the two scrapers 22 is also large. That is, the types of walls that the scraping tool can scrape are no longer limited to inside corners, outside corners, and flat surfaces, thus expanding the applicability of the scraping tool. Compared with existing adjustable-angle scraping tools, the scraping tool provided in this embodiment can change the overlap length of the first adjusting member 31 and the second adjusting member 32 by sliding or twisting, that is, to complete the adjustment of the included angle between the two scrapers 22 without disassembling any parts, making the operation convenient and quick.

[0043] Specifically, see Figure 2 When the length of the adjusting component 3 is the same as the dimension of the connecting rod 41 along the length of the adjusting component 3, the included angle α between the two scrapers 22 is 180°, and the scrapers 22 are in a horizontal state. At this time, the trowel can trowel the flat wall surface; see reference. Figure 3, increase the length of the overlap between the first adjusting member 31 and the second adjusting member 32, the total length of the adjusting assembly 3 becomes smaller, when the length of the adjusting assembly 3 is smaller than the size of the connecting rod 41 along the length direction of the adjusting assembly 3, the included angle between the two scrapers 22 will be smaller than 180°, at this time, the scraping tool can be used to scrape convex corners, and the angle range of the corners can be 0°-180°; further, when the included angle between the two scrapers 22 is 90°, the scraping tool can be used to scrape external corners; see Figure 4 , decrease the length of the overlap between the first adjusting member 31 and the second adjusting member 32, the total length of the adjusting assembly 3 becomes larger, when the length of the adjusting assembly 3 is larger than the size of the connecting rod 41 along the length direction of the adjusting assembly 3, the included angle between the two scrapers 22 will be larger than 180°, at this time, the scraping tool can be used to scrape concave corners, and the angle range of the corners can be 180°-360°; further, when the included angle between the two scrapers 22 is 270°, the scraping tool can be used to scrape internal corners.

[0044] Further, the adjusting assembly 3 is provided with an external corner identification part, an internal corner identification part and a flat surface identification part, the worker can quickly adjust the length of the overlap between the first adjusting member 31 and the second adjusting member 32 according to the position of the external corner identification part, and then realize the quick adjustment of the angle of the scraper 22 when scraping external corners; the internal corner identification part and the flat surface identification part have the same function as the external corner identification part, which will not be described here.

[0045] In this embodiment, see Figure 1 The connecting assembly 4 is provided with multiple groups, and the multiple groups of connecting assemblies 4 are arranged at intervals along the extension direction of the scraper 22 (Y direction in Figure 1 ) so that the angles of rotation of the scraper 22 at different positions can be the same; in other embodiments, the connecting assembly 4 is provided with one group and is located at the middle position of the scraper 22 along the extension direction thereof.

[0046] Exemplarily, see Figure 1 The handle 1 adopts a cylindrical body, which is convenient for the worker to hold during the scraping operation, and the worker can move the handle 1 to drive the scraper 22 to move, so as to scrape the wall surface.

[0047] Exemplarily, the scraper 22 is made of a steel plate, which has high flatness and is not easy to deform.

[0048] In an optional embodiment, see Figure 1 and Figure 5The first adjusting member 31 is rotationally connected with the handle 1. The first adjusting member 31 is provided with a threaded hole 311 extending along the length direction of the first adjusting member 31. The second adjusting member 32 is provided with a screw rod portion 321 threadedly matched with the threaded hole 311. One end of the screw rod portion 321 extends into the threaded hole 311, and the other end is connected with the rotation connecting member 21. By screwing the first adjusting member 31, the first adjusting member 31 can rotate relative to the second adjusting member 32, so that the length of the screw rod portion 321 extending into the threaded hole 311 changes, the overlapping length of the first adjusting member 31 and the second adjusting member 32 is adjusted, and the included angle between the two scrapers 22 is adjusted. The overlapping length of the first adjusting member 31 and the second adjusting member 32 is adjusted by using the threaded mode, so that the first adjusting member 31 and the second adjusting member 32 can overlap with any length, that is, the included angle between the two scrapers 22 can form any angle, which expands the application range of the scraping tool. Moreover, after the two scrapers 22 are adjusted to the required included angle, the first adjusting member 31 is not screwed, so the overlapping length of the first adjusting member 31 and the second adjusting member 32 will not change, and the included angle between the two scrapers 22 is fixed.

[0049] Exemplarily, the first adjusting member 31 is a threaded cylinder, and the second adjusting member 32 is a screw rod.

[0050] In the embodiment, referring to Figure 1 The handle 1 is provided with a connecting cylinder 11. The connecting cylinder 11 is provided with a bearing. The first adjusting member 31 is rotationally connected with the connecting cylinder 11 through the bearing at the end away from the second adjusting member 32, so as to rotationally connect the first adjusting member 31 with the handle 1.

[0051] Exemplarily, referring to Figure 1 The connecting cylinder 11 is arranged on the side of the handle 1 facing the scraper. In order to ensure that the rotatable angle of the scraper is large enough, the length of the connecting cylinder 11 is arranged to be small.

[0052] In another optional embodiment, referring to Figure 6 and Figure 7 One of the first adjusting member 31 and the second adjusting member 32 is provided with a sliding block 322 extending along the length direction of the adjusting assembly 3, and the other of the first adjusting member 31 and the second adjusting member 32 is provided with a sliding groove 312 slidably matched with the sliding block 322. In this way, the relative sliding of the first adjusting member 31 and the second adjusting member 32 is facilitated, and the sliding direction of the first adjusting member 31 and the second adjusting member 32 is guided.

[0053] In the embodiment, referring to Figure 7The first adjusting member 31 and the second adjusting member 32 are coaxially arranged, the first adjusting member 31 is an adjusting sleeve, a sliding groove 312 is arranged on the inner wall of the adjusting sleeve, the second adjusting member 32 is an adjusting rod, a sliding block 322 is arranged on the adjusting rod, the adjusting rod is slidingly inserted into the adjusting sleeve, and the length of the adjusting rod inserted into the adjusting sleeve is the length of the first adjusting member 31 and the second adjusting member 32 that overlap.

[0054] Further, the sliding block 322 can be arranged at the end of the adjusting rod or longitudinally arranged along the extension direction of the adjusting rod, so as to increase the length of the first adjusting member 31 and the second adjusting member 32 that can overlap, and expand the adjustable range of the included angle between the two scrapers 22.

[0055] In other embodiments, the first adjusting member 31 and the second adjusting member 32 can also be arranged in a skew axis. For example, the first adjusting member 31 and the second adjusting member 32 are both plate-shaped structures, the first adjusting member 31 and the second adjusting member 32 are arranged side by side, the plate surface of the first adjusting member 31 is attached to the plate surface of the second adjusting member 32, and the length of the first adjusting member 31 and the second adjusting member 32 that overlap is the length of the two plate surfaces that are attached.

[0056] In this embodiment, referring to Figure 1 , Figure 6 and Figure 7 , a plurality of limiting holes 313 are arranged on the first adjusting member 31 and spaced apart along the length direction of the first adjusting member 31, and an elastic limiting member 323 is arranged on the second adjusting member 32, the elastic limiting member 323 can be selectively clamped into any limiting hole 313 to fix the overlapping length of the first adjusting member 31 and the second adjusting member 32, so that the length of the adjusting assembly 3 is not only adjustable but also can be fixed after adjustment, and the scraper 22 can be stably fixed at the current angle. When the elastic limiting member 323 is selectively clamped into any limiting hole 313, the overlapping length of the first adjusting member 31 and the second adjusting member 32 is fixed, that is, the included angle between the two scrapers 22 is fixed; when the elastic limiting member 323 is disengaged from the corresponding limiting hole 313, the first adjusting member 31 and the second adjusting member 32 can slide relative to each other to adjust the overlapping length, and at this time, the included angle between the two scrapers 22 is adjustable.

[0057] Specifically, referring to Figure 7 , the elastic limiting member 323 includes a limiting member 3231 and an elastic member 3232, the second adjusting member 32 is provided with a mounting groove 324, the elastic member 3232 is located in the mounting groove 324, one end of the limiting member 3231 is movably inserted into the mounting groove 324 and abuts against the elastic member 3232, and the limiting member 3231 can be inserted into the limiting hole 313 under the elastic force of the elastic member 3232 to fix the overlapping length of the first adjusting member 31 and the second adjusting member 32.

[0058] For example, referring to Figure 1 and Figure 7, the first adjusting member 31 is an adjusting sleeve, the second adjusting member 32 is an adjusting rod, and the cross sections of the adjusting rod and the adjusting sleeve are both rectangular. The cross section of the limiting member 3231 is T-shaped, and the elastic member 3232 is a spring. The slider 322, the sliding groove 312, the mounting groove 324, the limiting member 3231, and the elastic member 3232 are all provided with two, so as to improve the stability of the relative sliding of the first adjusting member 31 and the second adjusting member 32. The two sliders 322 are respectively arranged on the two sides of the adjusting rod opposite to each other, the two sliding grooves 312 are respectively arranged on the two inner side walls of the adjusting sleeve opposite to each other, the two mounting grooves 324 can be respectively arranged on the two sides of the adjusting rod which are not provided with the sliders 322, the two elastic members 3232 are arranged in one-to-one correspondence with the two mounting grooves 324, and the two limiting members 3231 are connected with the two elastic members 3232 in one-to-one correspondence. One end of the spring is connected with the head of the T-shaped limiting member 3231, and the other end of the spring is connected with the groove wall of the mounting groove 324. When the rod part of the T-shaped limiting member 3231 is pressed into the adjusting sleeve under the action of an external force, the rod part of the T-shaped limiting member 3231 is separated from the corresponding limiting hole 313, and when the T-shaped limiting member 3231 moves in the mounting groove 324, the spring is compressed. At this time, the adjusting rod can slide relative to the adjusting sleeve, the overlapping length of the first adjusting member 31 and the second adjusting member 32 can be adjusted, and in the sliding process, the rod part of the T-shaped limiting member 3231 is extruded by the inner wall of the adjusting sleeve. When the rotating angle of the scraper 22 reaches the required angle, at this time, the limiting hole 313 is arranged at the corresponding position of the adjusting sleeve, the rod part of the T-shaped limiting member 3231 will no longer be extruded by the inner wall of the adjusting sleeve, the spring can automatically recover the deformation, the T-shaped limiting member 3231 will be automatically clamped into the corresponding limiting hole 313 under the action of the elastic force of the spring, and the fixing of the overlapping length of the adjusting sleeve is completed.

[0059] In the embodiment, the cross sections of the adjusting rod and the adjusting sleeve are both rectangular, which is more convenient for the arrangement of the slider 322, the sliding groove 312, and the mounting groove 324. In other embodiments, the cross sections of the adjusting rod and the adjusting sleeve can also be cylindrical or cylindrical, and the cross section shapes of the adjusting rod and the adjusting sleeve can be different, as long as the relative sliding of the adjusting rod and the adjusting sleeve can be realized.

When the overlapping length of the first adjusting member 31 and the second adjusting member 32 changes, the second adjusting member 32 drives the rotating shaft 211 to move along the length direction of the rotating shaft 211, so that the two connecting parts 212 rotate relative to the rotating shaft 211, and then drive the corresponding scraper 22 to move and rotate, so as to realize the adjustment of the included angle of the two scrapers 22.

[0061] Exemplarily, the connecting part 212 is a connecting plate, the scraper 22 is a steel plate, the connecting part 212 is attached to the scraper 22 and connected to the scraper 22 by bolts or welded to the scraper 22.
