In this embodiment, the second hydraulic telescoping rod 16 is activated to move the rebar in the direction of the front of the device. The position of the groove 15 coincides with the lowest rotating position of the through hole 5, and the steel bar passes through the inner cavity of the through hole 5 at the lowest position and extends to the front surface of the gear 4. The length of the second hydraulic expansion link 16, i.e., the length of the bar moving in the front direction, can be adjusted by manually cutting the length of the bar as needed.

The right side of the supporting seat 14 is provided with a cover plate 17, a hinge connection is arranged between the cover plate 17 and the supporting seat 14, and limiting holes 18 are formed in the top of the cover plate 17 and the top of the supporting seat 14.

Limiting holes 18 are formed in the tops of the cover plate 17 and the supporting seat 14, bolts are usually arranged at the limiting holes 18, penetrating through the cover plate 17 and the supporting seat 14, and fixing on the supporting seat 14 is achieved, so that the function of clamping reinforcing bars is achieved, and the reinforcing bars in the grooves 15 cannot shake in a large range in the cutting process.

Wherein the position of the recess 15 coincides with the lowest position of rotation of the through hole 5.

In this embodiment, the position of the groove 15 coincides with the lowest position of rotation of the through hole 5, and the reinforcing bar passes through the inner cavity of the through hole 5 at the lowest position, extends to the front face of the gear 4, and is cut off by rotation of the gear 4.

Working principle: first the cover 17 is rotated open about the hinge, the bars to be cut are placed in the cavities of the grooves 15, and then the cover 17 is closed. Limiting holes 18 are formed in the tops of the cover plate 17 and the supporting seat 14, bolts are usually arranged at the limiting holes 18, penetrating through the cover plate 17 and the supporting seat 14, and fixing on the supporting seat 14 is achieved, so that the function of clamping reinforcing bars is achieved, and the reinforcing bars in the grooves 15 cannot shake in a large range in the cutting process. At this time, the second hydraulic telescopic rod 16 is started to drive the reinforcing steel bars to move towards the front direction of the device. The position of the groove 15 coincides with the lowest rotating position of the through hole 5, and the steel bar passes through the inner cavity of the through hole 5 at the lowest position and extends to the front surface of the gear 4. The length of the second hydraulic expansion link 16, i.e., the length of the bar moving in the front direction, can be adjusted by manually cutting the length of the bar as needed.

Due to the limiting block 13, the gear 4 cannot be separated from the rotating shaft 3 in the rotating process. The sliding block 10 can move left and right in the inner cavity of the sliding groove 7, so that the sliding block 10 is more stable when moving downwards, and cannot shake in the front-back direction. The bottom of the sliding block 10 is provided with the protection pad 11, so that the contact part of the sliding block 10 and the sliding groove 7 can be increased, and the problem that the pressure intensity is too high due to too small contact area between the sliding block 10 and the sliding groove 7 is avoided, so that the inner cavity of the sliding groove 7 is damaged. In the clockwise rotation process of the gear 4, the steel bars in the inner cavity of the through hole 5 of the gear 4 are cut off, and the cut steel bars fall on the conveyor belt 12 due to gravity, so that the transfer is convenient. In the process of extending the first hydraulic telescopic rod 9 on the right side, the first hydraulic telescopic rod 9 on the left side is shortened, the sliding block 10 at the bottom of the first hydraulic telescopic rod 9 on the left side also slides in the corresponding sliding groove 7, so that the gear 4 finishes clockwise rotation, the through hole 5 originally positioned at the higher position rotates to the lowest position, at the moment, the first hydraulic telescopic rod 9 on the right side is in an extending state, and the first hydraulic telescopic rod 9 on the left side is in a contracted original factory state. After the cutting of the section of the steel bar is completed, the second hydraulic telescopic rod 16 continues to stretch at the moment, drives the steel bar to move towards the front direction continuously, and extends out of the position of the through hole 5 at the lowest position so as to complete the next cutting. When the steel bar is stretched to a specified length, the first hydraulic telescopic rod 9 on the left side is stretched, the first hydraulic telescopic rod 9 on the right side is shortened, and the gear 4 is driven to rotate anticlockwise to finish cutting. And so on, the section-by-section cutting of the reinforcing steel bar is completed.
