[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Example 1, please refer to Figures 1-5. This utility model provides a portable steel cutting machine, including a base 1, a first support plate 101, a shaft seat 102, a cutting groove 103, a storage groove 104, a first telescopic groove 105, a first spring 106, a cutting machine body 2, a second support plate 3, an adjustment groove 301, a connecting shaft 302, a positioning rod 4, a first support rod 401, a second telescopic rod 402, a second limiting block 403, a third telescopic groove 404, and a second... The base 1 includes a spring 405, a second support rod 5, a second telescopic groove 501, a slide rod 502, a limiting plate 6, a limiting rod 7, a first telescopic rod 701, and a first limiting block 702. The bottom of the base 1 is vertically fixed with a first support plate 101, and the top of the base 1 is provided with a cutting groove 103. The cutting groove 103 is distributed below the cutting machine body 2 to facilitate the cutting machine body 2 to cut the steel strip. Specifically, as shown in Figure 3 and Figure 5 As shown, the top of the first support plate 101 is provided with two sets of limiting rods 7, and the limiting rods 7 are slidably connected to the first support plate 101. The bottom of the limiting rods 7 is fixed with two sets of first telescopic rods 701, and the bottom sides of the first telescopic rods 701 are fixed with first limiting blocks 702. The connection between the first telescopic rods 701 and the first limiting blocks 702 and the first support plate 101 is provided with a first telescopic groove 105. The inside of the first telescopic groove 105 is provided with two sets of first springs 106. The length of the first springs 106 is greater than the length of the first telescopic groove 105. After the limiting rods 7 protrude, they can fix the two sets of limiting plates 6 after rotation, and can also limit and fix the second support plate 3. Specifically, as shown in Figures 3 and 5, the limiting rod 7 is located at the bottom of the second support plate 3 on the side away from the base 1, and the length of the limiting rod 7 is consistent with the spacing between the two sets of limiting plates 6. In this way, the limiting rod 7 can limit the two sets of limiting plates 6, so that the limiting plates 6 can better support the bottom of the second support plate 3. Specifically, as shown in Figure 1 and Figure 2 As shown, a cutting machine body 2 is installed on the top of the base 1, and two sets of second support plates 3 are symmetrically arranged on the side of the base 1. A connecting shaft 302 is provided at one end of the second support plate 3 near the base 1, and a shaft seat 102 is fixed at the connection between the base 1 and the shaft seat 102. Specifically, such as Figure 2 and Figure 4 As shown, a positioning rod 4 is slidably connected to the top surface of the second support plate 3. A first support rod 401 is rotatably connected to both ends of the positioning rod 4. A second telescopic rod 402 is fixed to the bottom end of the first support rod 401 near the second support rod 5. A second limiting block 403 is fixed to the end of the second telescopic rod 402 away from the second support rod 5. A second telescopic groove 501 is provided at the connection between the second support rod 5, the second limiting block 403, and the second telescopic rod 402. The second telescopic groove 501 and the first support rod 401... Sliding allows the positioning rod 4 to move on the surface of the second support plate 3, adjusting the distance between the second support plate 3 and the positioning rod 4, which facilitates clamping steel strips of different thicknesses. Specifically, as shown in Figure 2 and Figure 4 As shown, the lower end of the first support rod 401 is slidably connected to the second support rod 5. An adjustment groove 301 is provided at the connection between the second support rod 5 and the second support plate 3. The adjustment groove 301 is slidably and rotatably connected to the second support rod 5. This allows the positioning rod 4 to move on the second support plate 3 through the sliding of the second support rod 5 and the adjustment groove 301, thereby adjusting the position of the positioning rod 4. The positioning rod 4 can also be moved to one end of the second support plate 3 by rotating the second support rod 5 and the adjustment groove 301, so that the positioning rod 4 can be stored away. Specifically, such as Figure 4 and Figure 5As shown, a sliding rod 502 is fixed inside the second telescopic groove 501, and a third telescopic groove 404 is provided at the connection between the second telescopic rod 402 and the sliding rod 502. A second spring 405 is distributed on the outside of the sliding rod 502, and the second spring 405 is located inside the third telescopic groove 404. The length of the third telescopic groove 404 is greater than the length of the second spring 405. Through the extension of the second spring 405, the second telescopic rod 402 can be pushed downward in the opposite direction, so that the positioning rod 4 remains in close contact with the top surface of the second support plate 3, which is convenient for clamping the steel strip on the surface of the second support plate 3 and for cutting. Specifically, such as Figure 4 As shown in Figure 5, an adjustment groove 301 is provided at the connection between the side of the second support plate 3 and the second support rod 5. The side of the base 1 near the second support plate 3 is also rotatably connected to a limiting plate 6, and the limiting plate 6 is set between the base 1 and the second support plate 3. The height of the two sets of limiting plates 6 is consistent with the height of the bottom surface of the second support plate 3 from the base 1. A storage groove 104 is provided at the connection between the base 1 and the limiting plate 6, so that the limiting plate 6 can be rotated and stored inside the storage groove 104, which facilitates the folding and storage of the limiting plate 6.

[0017] In this embodiment of the application, when in use: by setting a second support plate 3 on the side of the base 1, the limiting rod 7 is first pressed down, and then the second support plate 3 can be rotated upward through the connecting shaft 302. Then, by rotating, the limiting plate 6 is rotated outward and unfolded, so that the limiting plate 6 can be placed against the bottom of the second support plate 3. After providing support, the limiting rod 7 is released, and the first spring 106 expands, pushing the limiting rod 7 upward so that the limiting rod 7 protrudes again from the top surface of the support plate 101. Then, the limiting rod 7 limits the limiting plate 6 to prevent the limiting plate 6 from rotating, thus better supporting the second support plate 3. The unfolded second support plate 3 allows the strip steel to be conveniently placed at the bottom of the cutting machine body 2, facilitating the cutting of the strip steel below. The strip steel can be limited and fixed by the positioning rod 4. The first support rod 401 and the second support rod 5 at both ends of the positioning rod 4 can be pushed closer to each other by the second spring 405, allowing the positioning rod 4 to be tightly attached to the second support plate 3. When the strip steel passes between the second support plate 3 and the positioning rod 4, it can be clamped, facilitating the cutting of the machine body 2. The steel strip is then cut, thus completing the use of this portable steel cutting machine. It should be noted that this utility model is a portable steel cutting machine, and all components are general standard parts or parts known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
