The surface of the movable rod 16 is fixedly connected to the second screw 18, and the surface of the second nut 19 is fixedly connected to the handle 20. The moving wheel 2 and the Y-shaped frame 3 form a placement rack for the rod body 4, and the movement of the single crystal silicon rod can be achieved through the moving wheel 2.
[0024] Furthermore, two groups of connecting rods 5 are provided, and the two groups of connecting rods 5 are arranged on both sides of the mounting frame 1. The number of connecting rods 5 in each group is two, and each group of connecting rods 5 is arranged on both sides of the rod body 4. The length of the connecting rod 5 is the same as the length of the slot 6. Two groups of connecting plates 7 are provided. Under the action of the connecting rod 5, the installation of the slider 9 can be realized, and then the installation effect of the connecting plate 7 and the pressure plate 12 can be achieved.
[0025] Furthermore, two sets of connecting plates 7 are installed at both ends of the pressure plate 12. The cross-section of the connecting plate 7 is "L"-shaped. One side of the connecting plate 7 is installed on the surface of the first screw 10 through the through hole 8. The other end of the connecting plate 7 is fixedly connected to the surface of the pressure plate 12. The cross-section of the slider 9 and the slot 6 is "T"-shaped. Under the action of the connecting plate 7, the pressure plate 12 is connected to the connecting rod 5 and moves along its surface. The cross-sectional size of the slider 9 is smaller than the cross-sectional size of the slot 6, which facilitates the slider 9 to slide on the surface of the slot 6, and when the first nut 11 is against the connecting plate 7, the slider 9 can be pressed against the slot 6.
[0026] Furthermore, the first screw 10 passes through the through hole 8 and is connected to the surface of the connecting plate 7. One end of the first screw 10 is fixedly connected to the surface of the slider 9. The other end of the first screw 10 is connected to the inner surface of the first nut 11 through a thread. The first nut 11 is abutted and connected to the surface of the connecting plate 7. Under the connection between the first screw 10 and the first nut 11, the connecting plate 7 can be disassembled and fixed.

The size of the anti-slip pad 13 is smaller than the size of the pressure plate 12, and the anti-slip pad 13 is made of rubber material, which will not cause damage to the rod body 4 when it is in contact with it, and can also increase the friction to make the limiting effect better.
[0028] Furthermore, one end of the movable rod 16 is fixedly connected to the surface of the limit plate 17, and the other end of the movable rod 16 is slidably connected to the inner surface of the sleeve plate 14. The limit plate 17 is abutted against the surface of the rod body 4, and the second screw 18 is movably connected to the surface of the connecting groove 15. The connection between the limit plate 17 and the sleeve plate 14 can be achieved through the movable rod 16, so that the limit plate 17 can move along the direction of the sleeve plate 14.
[0029] Furthermore, one end of the second screw 18 is fixedly connected to the surface of the movable rod 16, and the other end of the second screw 18 is connected to the inner surface of the second nut 19 through a thread, and the second nut 19 is abutted against the outer surface of the sleeve plate 14. Through the connection between the second screw 18 and the second nut 19, the movable rod 16 installed in the sleeve plate 14 can be limited and fixed, and then the limiting plate 17 can be fixed so that it is against the rod body 4 for limiting. At the same time, the hand handle 20 can be used to avoid the use of other tools to disassemble and assemble the second nut 19.
[0030] Working principle: When transporting the rod 4 being processed, first place the rod 4 on the Y-shaped frame 3, then insert the first screw 10 into the through hole 8 and connect it to the inner surface of the first nut 11 through a thread, so that the two sets of sliders 9 and the connecting plate 7 are connected, and then the slider 9 is inserted into the slot 6 so that the connecting plate 7 is attached to the outside of the connecting rod 5. At this time, the pressure plate 12 is moved along the direction of the connecting rod 5 to drive the slider 9 and the connecting plate 7 to slide on the surface of the slot 6 and the connecting rod 5 respectively. When the anti-slip pad 13 sticky on the surface of the pressure plate 12 stops against the rod 4, finally tighten the first nut 11 so that it rests on the connecting plate 7, it can prevent the rod 4 from rotating on the Y-shaped frame 3 when the device moves.
[0031] After placing the rod body 4, the movable rod 16 is inserted into the rod body 4 and the limit plate 17 is placed toward one side of the rod body 4, thereby driving the second screw 18 to slide on the surface of the connecting groove 15. When the limit plate 17 rests on the rod body 4, it stops. At this time, the second nut 19 is threadedly connected to the second screw 18 and tightened by rotating the handle 20 so that the second nut 19 rests on the outer surface of the sleeve plate 14. This can prevent the rod body 4 from sliding on the Y-shaped frame 3 when the device moves, thereby achieving the effect of limiting and fixing the single crystal silicon rod.
