The clamping structure also includes a movable edge 33, a movable slide groove 34, a movable slide groove 36, a movable slide groove 37, a movable slide groove 38, a movable slide groove 39, a movable slide groove 31, a movable slide groove 31, a movable slide groove 32, a movable slide groove 32, a movable slide groove 33, a movable slide groove 34, a movable slide groove 35, a movable slide groove 36, a movable slide groove 37, a movable slide groove 38, a movable slide groove 39, a movable slide groove 31, a movable slide groove 32, a movable slide groove 32, a movable slide groove 33, a movable slide groove 34, a movable slide groove 35, a movable slide groove 36, a movable slide groove 36, a movable slide groove 37, a movable slide groove 38, a movable slide groove 39, a movable slide groove 30, a movable slide groove 30, a movable slide groove 32, a movable slide groove 32, a movable slide groove 32, a movable slide groove 32, a 4. The fixed edge 41 and the fixed slide groove 42, the live edge 33 is fixedly connected to the top of the live rod 32, the live slide groove 34 is opened at the top of the live edge 33, the fixed edge 41 is fixedly connected to the top of the fixed rod 40, the fixed slide groove 42 is opened at the top of the fixed edge 41, the top of the fixed edge 41 is flush with the top of the live edge 33, the clamping structure also includes a live slider 35, a fixed slider 43, an alignment rod 45 and an alignment groove 37, the live slider 35 is slidably connected in the live slide groove 34, the fixed slider 43 is slidably connected in the fixed slide groove 42, the alignment rod 45 is fixedly connected to the wall surface of the fixed clamping plate 44 facing the live clamping plate 36, and the alignment groove 37 runs through the rear wall surface of the live clamping plate 36;

[0032] During specific use, first slide each fixed clamping plate 44 along the fixed slide groove 42 to the same size as the cut single crystal silicon rod. When sliding each fixed clamping plate 44, the movable rod 32 will slide in the fixed slide groove 42. When sliding, the fixed clamping plate 44 will drive the alignment rod 45 to slide at the same time. The alignment rod 45 will drive the movable clamping plate 36 to slide at the same time through the alignment groove 37. The movable clamping plate 36 will drive the movable slider 35 to slide in the movable slide groove 34. After the adjustment is completed, the single crystal silicon rod to be clamped can be placed on the top of the alignment rod 45 between each group of symmetrical fixed clamping plates 44 and movable clamping plates 36, and then the hydraulic rod 31 is controlled to retract through the control screen 21. The hydraulic rod 31 is electrically connected to the corresponding power supply.

When the single crystal silicon rod is clamped by the symmetrical movable clamping plates 36 and the fixed clamping plates 44 in the semicircular grooves opened on the wall surfaces, the clamping of the single crystal silicon rod is completed. At this time, the single crystal silicon rod can be cut with the cutting machine. When the single crystal silicon rod is cut into each section, it will still be clamped on the top of the operating table 20 by each group of symmetrical movable clamping plates 36 and fixed clamping plates 44. When the single crystal silicon rod needs to be removed, the hydraulic rod 31 can be controlled to extend to stop the symmetrical fixed clamping plates 44 and the movable clamping plates 36 from clamping the single crystal silicon rod.

[0033] To summarize, by setting up a clamping structure, a single single crystal silicon rod can be cut into multiple sections without the need for workers to carry it multiple times, because the clamping structure clamps the single single crystal silicon rod through multiple symmetrical movable clamps 36 and fixed clamps 44, and each set of movable clamps 36 and fixed clamps 44 can be flexibly adjusted to the desired position, so that each single crystal silicon rod does not need to be carried multiple times when cut into multiple sections. Therefore, compared with the prior art, this solution is faster and easier when cutting a single crystal silicon rod into multiple sections.

[0035] In specific use, when the single crystal silicon rod is placed between the movable clamping plate 36 and the fixed clamping plate 44, it will first be located on the top of the alignment rod 45;

[0036] In summary, by setting the alignment rod 45, the single crystal silicon rod can be prevented from falling off between the movable clamping plate 36 and the fixed clamping plate 44 when the single crystal silicon rod is placed and cut, because the alignment rod 45 will support the single crystal silicon rod on its top, thereby preventing the single crystal silicon rod from falling and causing an increase in cost.

[0037] Working principle: First, slide each fixed clamping plate 44 along the fixed slide groove 42 until it is consistent with the size of the cut single crystal silicon rod. When sliding each fixed clamping plate 44, the movable rod 32 will slide in the fixed slide groove 42. When sliding, the fixed clamping plate 44 will drive the alignment rod 45 to slide at the same time. The alignment rod 45 will drive the movable clamping plate 36 to slide at the same time through the alignment groove 37. The movable clamping plate 36 will drive the movable slider 35 to slide in the movable slide groove 34. After the adjustment is completed, the single crystal silicon rod to be clamped can be placed on the top of the alignment rod 45 between each set of symmetrical fixed clamping plates 44 and movable clamping plates 36, and then the hydraulic rod 31 is controlled to retract through the control screen 21. The hydraulic rod 31 is electrically connected to the corresponding power supply. The hydraulic rod 31 can receive the signal sent by the control screen 21 to perform Contraction. When the hydraulic rod 31 contracts, it will drive the movable rod 32 to slide in the movable groove 30. The movable rod 32 will drive the movable edge 33 and the movable slider 35 and the movable clamping plate 36 on the top of the movable edge 33 to slide toward the fixed rod 40 at the same time. When the movable clamping plate 36 slides, the alignment rod 45 will slide in the alignment groove 37. When the single crystal silicon rod is clamped by the symmetrical movable clamping plates 36 and the fixed clamping plates 44 in the semicircular grooves opened on the wall surfaces, the clamping of the single crystal silicon rod is completed. At this time, the single crystal silicon rod can be cut with the cutting machine. When the single crystal silicon rod is cut into each section, it will still be clamped on the top of the operating table 20 by each group of symmetrical movable clamping plates 36 and fixed clamping plates 44. When the single crystal silicon rod needs to be removed, the hydraulic rod 31 can be controlled to extend to stop the symmetrical fixed clamping plates 44 and the movable clamping plates 36 from clamping the single crystal silicon rod.
