On one side of the top of the processing table 2, there is a clamping mechanism 3. The clamping mechanism 3 includes a clamping arm 301, a limiting plate 302, a clamping base 303, a motor 1 305, a support rod 307, a lead screw 311, a return spring 308, and a moving support 312. At the bottom of the clamping base 303, there is an installation groove 310. Both sides of the inner wall of the installation groove 310 are slidably connected with clamping arms 301. At the bottom ends of the two clamping arms 301, there are fixedly connected moving supports 312. At the bottom of the clamping base 303, there is a lead screw 311. On one side of the lead screw 311, there is a motor 1 305. The output end of the motor 1 305 is fixedly connected to one end of the lead screw 311. On the top of the clamping base 303, there is a pipe fitting body 4 placed. On the inner sides of the two clamping arms 301, there are fixedly connected support rods 307. On the side walls of the two support rods 307, there are fixedly connected multiple return springs 308. One ends of the multiple return springs 308 are fixedly connected with support blocks 309. The bottom end of the clamping base 303 is slidably connected to the top end of the processing table 2. On one side wall of the clamping base 303, there is a fixedly connected handle 304. When the user cuts the pipe fitting body 4, the cutting machine body 1 can be started, and then the handle 304 is pulled to drive the clamping base 303 to move. The cutting machine body 1 can cut the pipe fitting body 4. The top ends of the two moving supports 312 are respectively slidably connected to the bottom end of the clamping base 303. The two ends of the lead screw 311 are respectively threadedly connected to the two moving supports 312. The threads at both ends of the lead screw 311 are opposite. On one side of the motor 1 305, there is a fixedly connected limiting plate 302. The top end of the limiting plate 302 is fixedly connected to the bottom end of the clamping base 303. The other end of the limiting plate 302 is rotatably connected to the other end of the lead screw 311. At the top end of the clamping base 303, there are fixedly connected two limiting seats 306.
