The working process and principle are as follows: firstly, at the initial position, the indicating marks 805 at both sides of the bending fixing frame 8 should be aligned with the zero scale line on the outside dial 9, the pull rod pipe to be bent is placed in the placing groove in the middle of the fixing disc 801, the driving cam 802 starts to rotate, the arc pressing blocks 803 at both sides are pushed to move inwards, at this time, the T-shaped rod 804 provides a guiding and positioning function, the buffer spring at the inner side of the T-shaped rod 804 is compressed, meanwhile, the pipe to be bent is fixed in the placing groove by the arc pressing blocks 803 at both sides, the driving gear 12 is driven to rotate by the external motor, because the right side of the rotating outer frame 10 is provided with a half circle of gear teeth meshed with the driving gear 12, the driving gear 12 drives the rotating outer frame 10 to rotate, at this time, the spacing column 11 on the rotating outer frame 10 can drive the pull rod to start to bend, and the dial 9 can rotate together with the rotating outer frame 10, and at the same time, through the indication of the indicating marks 805, the angle of the bending of the pull rod can be read on the dial 9.

After bending is completed, an external device drives the lifting plate 101 to move downwards, at the same time, the main shaft 102 and the connecting plate 4 move downwards simultaneously, the upper pressing plate 7 below the connecting plate 4 contacts the fixed disc 801 firstly, the upper pressing plate 7 covers the placing groove of the fixed disc 801, the possibility that a pull rod is suddenly stressed to burst out of the placing groove during cutting is prevented, when the upper pressing plate 7 is stressed, the positioning connecting rod 6 compresses the positioning spring 5 upwards, namely the upper pressing plate 7 can move upwards, the situation that when the lifting plate 101 continues to move downwards, the pressure between the upper pressing plate 7 and the fixed disc 801 is too high, so that the upper pressing plate 7 and the connecting plate 4 are cracked is prevented, when the lifting plate 101 continues to drive the main shaft 102 to move downwards, the hinged inclined rod 104 hinged to the outer side of the main shaft 102 gradually changes from an inclined state to a horizontal state, the guard plate 105 is pushed to move outwards, and when the L-shaped guard plate 105 moves outwards, the upper cutting edge 103 is exposed, and the spindle 102 continues to drive the cutting edge 103 to move downward, so as to start cutting the pull rod.

Meanwhile, when the lifting plate 101 descends, the short connecting rod 2 outside the main shaft 102 can be gradually changed into a horizontal state from an inclined state, meanwhile, the positioning block inside the outer frame 3 is pushed, the buffer spring is compressed, after the cutting process is finished, the buffer spring can drive the short connecting rod 2 and the lifting plate 101 to recover to the initial position through the positioning block, when the lifting plate 101 drives the main shaft 102 to move upwards, the hinged inclined rod 104 outside the main shaft 102 can drive the protection plate 105 to recover to the initial position again, namely, the protection plate 105 protects the cutting edge 103 again, and the possibility that a user touches the cutting edge 103 to cause an accident when taking materials is prevented.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
