Then, with the power provided by the motor 52, the rotation of the first gear 53, the crawler 54, the second gear 55 and the driving rod 56 is driven. Then, by using the bending post 57 fixedly connected to the back of the top of the driving rod 56, the bending post 57 is driven to move in an arc in the inner cavity of the calibration groove 24, so as to bend the bent pipe 6, realizing the reduction of labor intensity and production cost, improving work efficiency. Then, with the two angle scales 211 fixedly connected to the top of the operating table 21, it is convenient to control the angular movement of the bending post 57 and the control of the radian of the bent pipe 6 during bending, realizing a more accurate bending movement and avoiding the problems of errors and inaccuracies caused by manual bending. Moreover, by using the movement of the adjusting post 261 on the inner wall of the adjusting groove 25 and the movement of the mounting post 28 on the inner wall of several mounting grooves 27, the fixed-point fixing of both ends of the bent pipe 6 is facilitated, improving the convenience of use. And by manually turning the hand knob 263 to drive the first threaded shaft 262 to rotate in the inner wall of the adjusting post 261, the pushing block 264 is pushed to drive the buffer 265 to slide up and down on the inner wall of the sliding groove 266, improving the fitting degree between the two clamping blocks 267 on both sides and the inner wall of the adjusting groove 25 to prevent loosening. If there are errors in a very small number of bent pipes 6, the bent pipe 6 can be placed between the front and rear clamping blocks 33, and the telescopic rod 32 is used to control the clamping of the bent pipe 6. By manually turning the hand crank 44, the second threaded shaft 42 is driven to rotate on the front of the mounting block 41, so that the threaded correction block 43 is pushed to move back and forth on the inner wall of the two mounting sliding grooves 22, realizing the function of bending and correction.
