[0002] Curtain wall is the exterior wall of a building. It does not bear weight and is hung like a curtain, so it is also called a curtain wall. It is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings. It is composed of panels and a supporting structure system. It has a certain displacement ability relative to the main structure or a certain deformation ability itself, and is an exterior protective structure or decorative structure of the building that does not bear the effects of the main structure. During the normal curtain wall installation process, it is often necessary to cut the curtain wall due to the different sizes of the wall, and a handheld cutting machine is one of the indispensable equipment.

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0024] Example: Figure 1-4 As shown, the utility model provides a technical solution, a building curtain wall corner interface cutting device, including a cutting machine body 1, a cutting blade 2 is provided at one end of the cutting machine body 1, an adjustable limit assembly 3 is installed at one end of the cutting machine body 1, and the adjustable limit assembly 3 includes a fixed frame 301, a moving rod 302, an extrusion screw 303, a limit frame 304, a spring telescopic column 305 and a ball 306;

[0025] One end of the cutting machine body 1 is slidably connected to a fixed frame 301, and a moving rod 302 is slidably connected to the fixed frame 301. An extrusion screw 303 is threadedly connected to the fixed frame 301. The end face of the extrusion screw 303 contacts the end face of the moving rod 302, which is convenient for fixing the moving rod 302. A limit frame 304 is installed at the bottom of the moving rod 302 by screws. The limit frame 304 is located outside the cutting blade 2. The ball 306 contacts the cutting blade 2, which is convenient for limiting the cutting blade 2 and limiting the position of the cutting machine body 1 when it moves. At the same time, it is convenient for positioning the cutting blade 2. Spring telescopic columns 305 are evenly installed inside the limit frame 304 through screws, and balls 306 are rotatably embedded in the spring telescopic columns 305.

[0026] A positioning assembly 4 is provided on the outside of one end of the cutting machine body 1. The positioning assembly 4 includes a fixed rod 401, a moving block 402, a mounting rod 403, an adjusting screw 404 and a limiting plate 405;

[0027] A fixed rod 401 is installed on one side of the cutting machine body 1 by a screw, and two moving blocks 402 are slidably connected inside the fixed rod 401. A T-slot is provided at the position of the fixed rod 401 corresponding to the moving block 402, and the moving block 402 is slidably connected to the inside of the T-slot to avoid the problem of the moving block 402 falling. The two moving blocks 402 are connected by a mounting rod 403. The cross-section of the mounting rod 403 is U-shaped, and the end face of the limit plate 405 is provided with an arc angle. The end face of the limit plate 405 contacts the end face of the mounting rod 403 to ensure the stability of the movement of the limit plate 405 and facilitate the limiting of human hands. An adjusting screw 404 is threadedly connected to the inside of the mounting rod 403, and one end of the adjusting screw 404 is rotatably connected to the limiting plate 405.

[0028] When using the cutting machine body 1, personnel use the cutting blade 2 to cut the corner interface of the curtain wall. Before cutting, the personnel move the limit frame 304 to a suitable position, and then fix the moving rod 302 by squeezing the screw 303, thereby fixing the limit frame 304 in a suitable position. When using the cutting machine body 1 for cutting, when the limit frame 304 contacts the wall, the cutting machine body 1 cannot move, so the cutting depth can be positioned to avoid the problem of over-cutting. In addition, during the cutting process, the ball 306 contacts the cutting blade 2 to position the two ends of the cutting blade 2, thereby ensuring the stability of the cutting blade 2 during cutting. At the same time, it can prevent the cutting blade 2 from being blocked when damaged, thereby preventing the cutting blade 2 from splashing.

[0029] When a person takes the cutting machine body 1, he / she puts his / her hand into the mounting rod 403, and then he / she rotates the adjusting screw 404 to drive the limit plate 405 to move, thereby limiting the person's hand. Then, the person can separate the hand from the cutting machine body 1 when using the cutting machine body 1, thereby preventing problems that affect the cutting of the cutting machine body 1. Through the movable mounting rod 403, the cutting machine body 1 can be used in different positions.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
