[0032] Reference Figure 2-5 As shown, this embodiment discloses that a handle block 24 is symmetrically fixedly connected to one side of the ejector rod 23, and the longitudinal section of the handle block 24 is in a T-shape. By providing the handle block 24, the contact area of ​​one side of the ejector rod 23 can be increased, so that it is convenient to grasp one side when pulling it. The first limit block 25 is fixedly connected to both ends of the ejector rod 23, and the inner wall of the card slot 5 near the two ends of the clamp frame 1 is symmetrically provided with a limit groove 26, and the inner wall of the limit groove 26 is slidably connected to the outer surface of the first limit block 25. By providing the limit groove 26 and the first limit block 25, the two ends of the ejector rod 23 can be limited, so that it is not easy to shake when sliding up and down, and the movement is more stable.

[0033] Reference Figure 2-5As shown, this embodiment discloses that one side of the limit rod 22 is fixedly connected with an anti-sliding block 27, and the anti-sliding block 27 is made of rubber. By providing the anti-sliding block 27, the contact friction force on one side of the limit rod 22 can be increased, so that when one end of the limit rod 22 abuts against the ejection rod 23 to limit and fix it, it is not easy to move away by itself, and the limit is more secure.

When the wafer is placed in the card slot 5 for limiting and fixing, the two limiting plates 32 will be squeezed outward to a certain distance, so that the springs 31 will shrink, and at the same time, the springs 31 will drive the limiting plates 32 to reset and abut on the surface of the placed wafer, limiting it, so that it is not easy to shake in the card slot 5 during cleaning, and at the same time, according to the thickness of the placed wafer, the degree of deformation and shrinkage of the spring 31 will be different, and the distance of resetting the limiting plates 32 will also be different, so that wafers of different thicknesses can be limited.

[0035] Reference Figure 6 and Figure 7 As shown, the present embodiment discloses that the inner wall of the card slot 5 is symmetrically fixedly connected with a plurality of telescopic rods 33, one end of the telescopic rod 33 is fixedly connected with one side of the limit plate 32, and the telescopic rod 33 is sleeved and connected with the spring 31.

A protective pad 34 is fixedly connected to one side of the limit plate 32, and the protective pad 34 is made of silicone. By setting the protective pad 34, the softness of the surface of the limit plate 32 can be increased, so that the wafer is not easy to be scratched and damaged when it abuts against the limit plate 32. Both sides of the limit plate 32 are fixedly connected with a second limit block 35, and the second limit block 35 is fixed in an inclined manner on one side of the limit plate 32 near the bottom and the inner wall opening of the clamp frame 1. By setting the second limit block 35, it is convenient for the wafer to be stuck between the two limit plates 32, and it is also convenient for the ejection rod 23 to slide out.

[0036] Working principle: when the clamp frame 1 is used to limit and fix the quartz wafer during the cleaning process, the wafer will be placed and clamped into the slot 5 on the inner wall of the clamp frame 1 so that it abuts against one side of the ejector rod 23, and then the hook will be hung inside the hook hole 4 on the clamp frame 1, and it will be placed in the cleaning liquid for cleaning. After cleaning it, the limit rod 22 is first rotated to one end on one side of the clamp frame 1 to a certain angle, so that one end and the anti-sliding block 27 are removed from the ejector rod 23, and then the handle block 24 can be manually held to pull the ejector rod 23 outward to a certain position in the inner wall of the mounting groove 21 and the slot 5, so that the cleaned wafer can be ejected from the inner wall of the clamp frame 1 and the inner wall of the slot 5, which is convenient for taking it out, thereby facilitating its continued use later, thereby improving the processing efficiency of wafer cleaning.

[0037] When the wafer is placed into the card slot 5 for limiting and fixing, the two limiting plates 32 will be squeezed outward to a certain distance, causing the spring 31 and the telescopic rod 33 to shrink. At the same time, the spring 31 will drive the limiting plate 32 to reset and abut against the surface of the wafer, limiting it so that it is not easy to shake in the card slot 5 during cleaning. At the same time, according to the thickness of the wafer placed, the degree of deformation and contraction of the spring 31 will be different, and the distance of resetting the limiting plate 32 will also be different, so that wafers of different thicknesses can be limited.
