[0026] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the left side surface of the support frame 2 is fixedly connected with a forward - reverse motor 303. The output end of the power of the forward - reverse motor 303 penetrates the support frame 2 and extends to the inside of the support frame 2. The upper surface of the support plate 1 is fixedly connected with five groups of support blocks 312, and the inner wall of each support block 312 is rotatably connected with a rotating wheel 313. By setting the support blocks 312 and the rotating wheels 313, a support effect can be provided for the seamless pipe, and at the same time, it is also convenient for the staff to push the seamless pipe for cutting work.

[0027] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the output end of the power of the forward - reverse motor 303 is fixedly connected with a threaded rod 308. The outer surface of the threaded rod 308 is rotatably connected with the inner wall of the support frame 2. The upper surface of the limit frame 302 is fixedly connected with two limit columns 316, and the outer surface of each limit column 316 is slidably connected with the inner wall of the support frame 2. By setting the limit columns 316, good stability can be provided for the limit frame 302 when it moves up and down, enabling it to descend smoothly.

[0028] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4, a moving block 304 is threadedly connected to the outer surface of the threaded rod 308.

[0031] Working principle: When in use, first, the staff transports the device to a suitable working position, and then turns on the power supplies of the forward and reverse motor 303, the rotating motor 306, and the electric telescopic rod 301 to make them in a stable powered-on state. When the seamless pipe needs to be cut, the staff places the seamless pipe on the rotating wheel 313 in sequence, and then pushes the seamless pipe into the interior of the support frame 2 and to a suitable cutting position. Subsequently, the electric telescopic rod 301 is turned on. After the electric telescopic rod 301 is turned on, it can generate power and extend. The extension of the electric telescopic rod 301 can push the limit frame 302 downward until it contacts and presses the seamless pipe below, thereby increasing the firmness effect of the seamless pipe. Subsequently, the rotating motor 306 and the forward and reverse motor 303 are turned on. After the rotating motor 306 and the forward and reverse motor 303 are turned on, they can generate power and rotate. The rotating motor 306 can drive the rotating shaft 307 to rotate. Under the rotation of the rotating shaft 307, the cutting blade 309 can be driven to rotate at a high speed. At the same time, the rotation of the forward and reverse motor 303 can drive the threaded rod 308 to rotate. Under the action of the rotation of the threaded rod 308, the moving block 304 and the moving frame 305 can be driven to move, so that the cutting blade 309 on the moving frame 305 can be driven to move. With the cooperation of the two motors, the seamless pipe can be cut quickly and continuously, thus greatly improving the cutting efficiency of the device for the seamless pipe.
