[0004] To address the shortcomings of existing technologies, this utility model provides a metal tower cutting machine, which solves the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a metal tower cutting machine, including an angle grinder, a cutting disc fixedly mounted on the angle grinder, and a first handle mounted on the angle grinder. A mounting frame is fixedly installed on the side of the angle grinder away from the first handle. A guide rail is slidably connected to the inner side of the mounting frame. A second handle is fixedly installed on the outer side of the guide rail, and a limiting mechanism located inside the mounting frame is provided on the outer side of the guide rail. A rotating shaft is movably sleeved inside the guide rail. A first pressure plate is rotatably connected to the outer side of one end of the rotating shaft. A fixing rod is movably sleeved inside the first pressure plate. A second pressure plate is fixedly sleeved on the outer side of one end of the fixing rod. A bolt with one end movably sleeved inside the first pressure plate is threaded inside the second pressure plate.

[0006] Preferably, the bolt is engaged with a second retaining ring located on one side of the first pressure plate.

[0007] Preferably, the limiting mechanism includes a first fixing plate and a second fixing plate disposed on the outside of the guide rail. The first fixing plate and the second fixing plate are movably sleeved together with a limiting rod whose end is movably sleeved inside the rotating shaft. The outer side of the limiting rod is engaged with a first retaining ring, and the outer side of the limiting rod is fitted with a spring located between the second fixing plate and the first retaining ring. The outer side of the end of the limiting rod extending outside the second fixing plate is fixedly sleeved with a push plate.

[0008] Preferably, a support plate located below the fixing rod is provided on the outer side of the first pressure plate.

[0009] This utility model has the following advantages:

[0010] 1. By tightening the bolts, the first and second pressure plates can be fixedly installed on the outside of the tower angle steel. Then, the angle grinder can be supported by the mounting bracket, guide rail and rotating shaft. At this time, the operator can drive the angle grinder to rotate around the axis of the rotating shaft by the second handle and push the angle grinder along the outside of the guide rail by the first handle, thereby adjusting the position of the cutting blade and ensuring that the cutting blade can cut along the outside of the angle steel. With this structure, the cutting machine can be installed on the outside of the angle steel, and the operator does not need to hold the cutting machine to operate it. Even if the operator works for a long time, the operator is not likely to get tired, and the danger is low.

[0011] 2.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 4A metal tower cutting machine includes an angle grinder 1, a cutting disc 2 fixedly mounted on the angle grinder 1, and a first handle 3 mounted on the angle grinder 1. A mounting frame 4 is fixedly mounted on the side of the angle grinder 1 away from the first handle 3. A guide rail 5 is slidably connected to the inner side of the mounting frame 4. A second handle 6 is fixedly mounted on the outer side of the guide rail 5. A limiting mechanism 7 located inside the mounting frame 4 is provided on the outer side of the guide rail 5. A rotating shaft 8 is movably sleeved inside the guide rail 5. A first pressure plate 9 is rotatably connected to the outer side of one end of the rotating shaft 8. A fixing rod 10 is movably sleeved inside the first pressure plate 9. A second pressure plate 11 is fixedly sleeved on the outer side of one end of the fixing rod 10. A bolt 12 with one end movably sleeved inside the first pressure plate 9 is threaded inside the second pressure plate 11.

[0019] The bolt 12 is secured to the outside by a second retaining ring 13 located on one side of the first pressure plate 9. The second retaining ring 13 can limit the bolt 12, so that the second pressure plate 11 can be moved along the axial direction of the fixing rod 10 during the loosening of the bolt 12, so as to facilitate the disassembly of the first pressure plate 9 and the second pressure plate 11 from the outside of the angle steel.

[0020] The limiting mechanism 7 includes a first fixing plate 71 and a second fixing plate 72 disposed on the outside of the guide rail 5. A limiting rod 73, one end of which is movably sleeved inside the rotating shaft 8, is movably sleeved inside the first fixing plate 71 and the second fixing plate 72. The limiting rod 73 can limit and fix the rotating shaft 8, so that the guide rail 5 will not fall out of the rotating shaft 8. The guide rail 5 can be rotated around the axis of the rotating shaft 8 by the second handle 6. A first retaining ring 74 is engaged on the outside of the limiting rod 73, and a spring 75 is sleeved on the outside of the limiting rod 73 between the second fixing plate 72 and the first retaining ring 74. The elastic force of the spring 75 can push the limiting rod 73 through the first retaining ring 74, thereby ensuring that the limiting rod 73 will not automatically detach from the inside of the rotating shaft 8. A push plate 76 is fixedly sleeved on the outside of the end of the limiting rod 73 that extends outside the second fixing plate 72. The push plate 76 can pull the limiting rod 73 and move the limiting rod 73 out of the inside of the rotating shaft 8.

[0021] The first pressure plate 9 is provided with a support plate 14 located below the fixing rod 10 on its outer side. The support plate 14 supports the first pressure plate 9 and the second pressure plate 11 when they are placed on the outside of the angle steel. At this time, the first pressure plate 9 and the second pressure plate 11 can be fixed on the outside of the angle steel by tightening the bolt 12 with a wrench. During this process, the two outer sides of the angle steel can be in contact with the first pressure plate 9 and the support plate 14, thereby ensuring that the cutting blade 2 of the angle grinder 1 can perform cutting operations perpendicular to the surface of the angle steel after installation.

[0022] Working principle: After placing the first pressure plate 9 and the second pressure plate 11 at the part of the tower rod angle steel that needs to be cut, the first pressure plate 9 and the support plate 14 are placed against the outside of the angle steel. While rotating the bolt 12 with a wrench, the second pressure plate 11 can be moved along the axial direction of the fixing rod 10. After the bolt 12 is fully tightened and fixed, the limit rod 73 is pulled by the push plate 76. At this time, the spring 75 can be compressed by the first retaining ring 74, and the guide rail 5 is fitted on the outside of the rotating shaft 8. The spring 75 is then released. At this time, the elastic force of the spring 75... While the lower limit rod 73 moves, it is inserted into the inside of the rotating shaft 8 to complete the installation of the angle grinder 1. At this time, the angle grinder 1 is started, and the cutting blade 2 is driven to rotate by the angle grinder 1. One hand of the operator holds the first handle 3 and the other hand holds the second handle 6. The guide rail 5 is rotated around the axis of the rotating shaft 8 by the second handle 6, and the angle grinder 1 rotates synchronously around the axis of the rotating shaft 8. The angle grinder 1 is pushed by the first handle 3. When the cutting blade 2 contacts the angle steel, the cutting operation of the angle steel begins.
