[0022] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0023] The attached figure shows a specific embodiment of a waterproof base internal and external corner arc processing tool of the utility model. The embodiment includes a handle, an external corner arc-smoothing plate mechanism and an internal corner arc-smoothing plate mechanism. Figure 3 As shown, the internal corner arc-smoothing plate mechanism includes a semi-cylindrical body 1, at both ends of which are fixedly welded circular head thin plates 5, and the cylindrical body connected by the circular head thin plates is arranged to be hollow; the outer side of the internal corner arc-smoothing plate mechanism is a hollow semi-cylindrical body structure and the middle is a cylindrical body structure; interlocking strips 4 are arranged at the two edges of the semi-cylindrical body 1.

[0024] As attached Figure 4 As shown, the external corner arc-smoothing plate mechanism includes a semi-cylindrical body 2, and interlocking grooves 3 are provided on both edges of the semi-cylindrical body 2.

[0025] As attached Figure 1 , which is a structural diagram after the interlocking card strip and the interlocking card slot are connected in cooperation; the hollow semi-cylindrical body 2 of the male corner arc-wiping plate mechanism has the same diameter as the semi-cylindrical body 1, and the semi-cylindrical body 1 is connected to the semi-cylindrical body 2 through the interlocking card slot and the interlocking card strip to form a complete cylindrical body; Figure 1 It is a state diagram when the utility model is used as a tool for smoothing arcs at internal corners. When in use, the handle is held by hand, and the arc surface of the outer cylinder of the semi-cylindrical cylinder is used to smooth arcs at internal corners.

[0026] When used as a tool for smoothing the arc of external corners, the semi-cylindrical body 1 and the semi-cylindrical body 2 are disconnected, and a rubber strip is set in the interlocking slot of the semi-cylindrical body 2, and the rubber strip is placed in the interlocking slot. The size of the rubber strip is the same as that of the interlocking strip. The rubber strip is set to prevent the mortar from entering the interlocking slot when smoothing the arc of external corners, affecting its connection with the interlocking strip. When used as a tool for smoothing the arc of internal corners, the rubber strip is taken out, and then the interlocking strip and the interlocking slot are connected. The inner arc surface of the semi-cylindrical body 2 is used for smoothing the arc of external corners. Because the handle is set on the semi-cylindrical body 2, it is not necessary to disassemble and replace the handle regardless of whether the arc of external corners or internal corners is smoothed.

[0027] The handle includes a wooden grip 9 and a connecting rod 8. The wooden grip 9 is installed on the connecting rod 8. The connecting rod is triangular and connected to the semi-cylindrical body 2 of the external corner arc-smoothing plate mechanism. The back of the semi-cylindrical body 2 is provided with a handle positioning thread hole 6, and the handle is provided with a connecting screw 7 connected to the positioning thread hole 6 of the external corner arc-smoothing plate mechanism. The handle body is provided with a wooden grip 9, and the wooden grip 9 is fixedly connected to the external corner arc-smoothing plate mechanism through the connecting rod 8 and the connecting screw 7. The wooden grip 9 is also provided with a grip groove 10, which increases the comfort of the user's grip and enhances the anti-slip effect. An arc-shaped protective plate with its center in the direction of the wooden grip is fixedly provided on the handle connecting rod 8 to protect the hands of the staff from being dirty by mortar.

[0028] The material of the semi-cylindrical body 1 and the semi-cylindrical body 2 is aluminum alloy; the material is easy to obtain, light and durable.

[0029] The connecting sides of the inner corner arc-smoothing plate mechanism and the outer corner arc-smoothing plate mechanism are respectively provided with an interlocking card strip 4 and an interlocking card slot 3. The interlocking card strip is inserted into the interlocking card slot to realize the connection between the semi-cylindrical cylinder body 1 and the semi-cylindrical cylinder body 2. This structure realizes the convenience of using the outer corner arc-smoothing plate mechanism or the inner corner arc-smoothing plate mechanism alone.

[0030] The two ends of the internal corner arc-smoothing plate mechanism are respectively provided with head thin plates. When the internal corner arc-smoothing plate is used for horizontal movement and scraping, the paint on the wall surface will not be scraped off. At the same time, the mortar at the internal corner is prevented from entering the cylinder to increase the weight of the cylinder, and the workers are prevented from repeatedly cleaning the mortar entering the cylinder, thereby ensuring the flatness of the scraped wall surface and facilitating construction. The handle body is provided with connecting screws that are inserted into the positioning thread holes, so that the handle body can be easily installed and disassembled with internal and external corner arc-smoothing cylinders of different diameters, and it is convenient to replace external corner arc-smoothing plate mechanisms and internal corner arc-smoothing plate mechanisms of different specifications.
