However, the T-shaped rail sawing method is suitable for sawing with shorter length, for example, short-distance sliding T-shaped rails on some common machines can be used in the sawing method. However, the sawing method has the following disadvantages: 1. because the sawing mode firstly saw the long section T-shaped track and then saw the long section T-shaped track one by one, each T-shaped track saw can generate head materials and tails, thereby causing the waste of section bars; 2. the production and sawing of the T-shaped track cannot be continuous and connected, and the sawing efficiency is very low; 3. the sawing can not be suitable for sawing very long T-shaped rails, for example, the standard length of the T-shaped rails used on an elevator is four meters or five meters, so for sawing the super-long section bar, the length of the T-shaped rail section bar produced by a production line is generally 40 meters or 50 meters when the section bar is sawn, if the section bar is sawn in the previous sawing mode, the section bar of 40 meters or 50 meters is firstly transported to a sawing place and then is sawn in a feeding way, the whole process is very complex, the space requirement on the place of a workshop is higher, and the implementation difficulty is high; the 4.T-shaped rail is special in shape, so that a common clamp cannot stably clamp, the sawing quality is reduced, and the elevator guide rail is required to be in butt joint, so that the requirement on profile sawing is particularly high;
