The working principle is as follows: when the invention is used, as shown in fig. 1 and fig. 6, firstly, the PLC control panel 5 is operated through the control switch 19, so that the PLC control panel 5 synchronously controls the telescopic ends of the first electric telescopic rod 55 and the second electric telescopic rod 57 to retract to the maximum extent (as shown in fig. 1), so that the mounting plate 48 and the first mounting plate 49 are respectively attached to the top end and the inner bottom end of the box body 1, further, the distance between the upper pressure wheel 50 and the lower pressure wheel 51 is expanded to the maximum extent, then, the telescopic end of the electric telescopic rod 26 is controlled to extend to the maximum extent through the control switch 19, when the telescopic end of the electric telescopic rod 26 extends to the maximum extent, the electric telescopic rod 26 pushes the cylinder body 28 to be attached and communicated with the small-caliber end of the trumpet-shaped cylinder body 6, at this time, the second spring 44 is in a compressed state, under the acting force of the second spring 44, the retainer ring 38 pulls the steel wire rope 39, in the process, the wire rope 39 can pull the pressing block 36 to rise, so that the bottom of the pressing block 36 is pulled out from the inner cavity of the barrel 28, the pressing block 36 is pulled upwards to synchronously drive the sleeve 34 to rise, the sleeve 34 can extrude the spring 35 to contract when rising, after the work is done, the coiled steel bar required to be straightened is placed beside the device, then the steel bar head which is just coiled is found out and inserted into the barrel 28 through the trumpet-shaped barrel 6, due to the arrangement of the trumpet-shaped barrel 6, the inner arc surface of the trumpet-shaped barrel 6 plays a role in guiding the steel bar head inserting work, the steel bar head inserting work is facilitated, after the steel bar head enters the barrel 28, the control switch 19 controls the telescopic end of the electric telescopic rod 26 to retract, when the telescopic end of the electric telescopic rod 26 retracts, the first square rod 41 is driven to synchronously move, and the second spring 44 on the first square rod 41 is not compressed in the process, when the second spring 44 is not compressed, the pressing block 36 pushes the pressing block 36 back to descend under the action of the spring 35, so that the bottom of the pressing block 36 extends into the barrel 28 to extrude the steel bar head, when the pressing block 36 descends, the steel wire rope 39 pulls the retainer ring 38 to make the retainer ring 38 slide towards the pressing block 36, as the steel bar head is pressed and fixed in the barrel 28 by the pressing block 36, the barrel 28 pulls the steel bar head along with the backward movement of the telescopic end of the electric telescopic rod 26, in the process, the first spring 43 is compressed along with the return of the first square rod 41, the retainer ring 38 continues to slide towards the pressing block 36 under the action of the first spring 43 until the trapezoidal block 37 on the side wall of the retainer ring 38 presses the inclined surface at the top of the pressing block 36, so that the pressing block 36 is always under the action of the first spring 43, when the pressing block 36 is under the action of the first spring 43, the bottom of the pressing, thus, with the continued retraction of the electric telescopic rod 26 (as shown in fig. 6), the barrel 28 will pull the coiled steel bar through the steel bar head fixed inside it until the telescopic end of the electric telescopic rod 26 retracts to the maximum extent (as shown in fig. 7), at this time, the side end of the barrel 28 will be inserted into the square positioning cylinder 22, during this process, the side end of the barrel 28 will push against the inclined surface at the bottom of the square positioning rod 23, so that the bottom of the square positioning rod 23 rises and fits the top end of the barrel 28 to fit and slide, until the bottom of the square positioning rod 23 is inserted into the positioning groove 47 at the top of the barrel 28 under the action of the tension spring 25, at this time, the steel bar pulled into the box 1 may be in a state of bending and not tightening, so that the steel bar when entering from the trumpet-shaped barrel 6 needs to be clamped and fixed into the C-shaped plate 7, when the steel bar is fixed in the C-shaped plate 7, the, after the reinforcing steel bars are fixed in the C-shaped plate 7, the first threaded rod 15 is screwed by the first handle 16, so that the vertical plate 12 drives the C-shaped plate 7 to move towards the first handle 16, in the process, the C-shaped plate 7 can effectively tighten the reinforcing steel bars between the cylinder body 28 and the C-shaped plate 7, when the reinforcing steel bars between the cylinder body 28 and the C-shaped plate 7 are tightened (as shown in figure 8), the telescopic ends of the first electric telescopic rod 55 and the second electric telescopic rod 57 are synchronously controlled by the control switch 19 and the PLC control panel 5 to extend to the maximum degree, the bottom of the upper pressing wheel 50 correspondingly arranged at the moment is attached to the top of the lower pressing wheel 51, and the reinforcing steel bars are just clamped and sleeved between the upper pressing wheel 50 and the lower pressing wheel 51, so that after the reinforcing steel bars between the cylinder body 28 and the C-shaped plate 7 are clamped by the upper pressing wheel 50 and the lower pressing wheel 51, the threaded rod 10 is screwed, then the telescopic end of the electric telescopic rod 26 is controlled to extend for a certain distance by the control switch 19, and the cylinder 28 is limited by the square positioning rod 23 and fixed in the square positioning cylinder 22, so that the cylinder 28 does not move when the telescopic end of the electric telescopic rod 26 extends, the second spring 44 is compressed, the second spring 44 can bounce the retainer ring 38 to be attached to the limiting ring 40 (at this time, the operation of the electric telescopic rod 26 can be stopped), the retainer ring 38 pulls the press block 36 to rise through the steel wire rope 39, the steel bar head in the cylinder 28 is loosened at the bottom of the press block 36, the threading process of the steel bar head is completed, at this time, the plurality of transmission motors can be synchronously started, the steel bar is clamped and transmitted between the upper press wheel 50 and the lower press wheel 51, and the purpose of straightening the steel bar is achieved in the transmission.
