[0024] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0026] Embodiment 1, as Figures 1-5 shown, the present utility model provides a flower basket for improving basket tooth marks, including two columns 1. Between the two columns 1, there are two moving plates 2. At one end of the two moving plates 2 facing each other, a plurality of shark diamond teeth 3 are equidistantly distributed. Inside the two columns 1, there is a driving structure 4 for driving the two moving plates 2 to move towards or away from each other. At both ends of the outer walls of the two columns 1, support blocks 12 are fixed. Inside each of the two support blocks 12, a plurality of slots 13 are opened. Inside the slots 13, limit baffles 14 are inserted. Inside the support blocks 12, there is an installation and disassembly structure 16 for installing and disassembling the limit baffles 14.

[0027] The overall effect achieved by the entire Embodiment 1 is that through the operation of the driving structure 4, the two moving plates 2 can be driven to move towards or away from each other, so as to adjust the distance between the two moving plates 2, which is convenient for adjustment according to the length of different silicon wafers, and has stronger practicability. The side teeth of traditional flower baskets include shark teeth, small diamond teeth, flat teeth, pointed teeth, etc. In this patent, by changing the shape of the basket teeth on the side of the flower basket and combining the shapes of small diamond teeth and shark teeth, the contact area between the shark tooth type flower basket and the silicon wafer is reduced, enabling better circulation of chemical reagents and water at the contact position between the silicon wafer and the flower basket, enabling the chemical reagents to fully contact the silicon wafer, making the reaction on the surface of the silicon wafer uniform, and forming a uniform velvet surface. At the same time, when slowly lifting, the shark diamond teeth 3 extend the length of the teeth, enabling water to fall better, preventing wall hanging, and preventing basket tooth marks from being formed during drying. Through the settings of the support blocks 12, the limit baffles 14, and the slots 13, when the silicon wafer is installed between the two moving plates 2, according to the length of the silicon wafer, the limit baffles 14 are inserted into different slots 13 to limit the two ends of the silicon wafer, avoiding accidental sliding of the silicon wafer, and having stronger stability. Through the setting of the installation and disassembly structure 16, the limit baffles 14 inserted into the slots 13 can be installed to prevent accidental sliding.

[0028] Embodiment 2, as Figures 1-5As shown, the driving structure 4 includes connecting plates 401 installed at both ends of the moving plate 2. A screw rod 402 is provided in one of the columns 1. A first docking plate 403 is threadedly connected to the outer wall of the screw rod 402. The first docking plate 403 is fixed to one of the connecting plates 401. The other connecting plate 401 is fixed with a second docking plate 404. A limiting column 405 is slidably connected in the second docking plate 404. The installation and removal structure 16 includes an inner cavity 1601 opened in the support block 12 on one side of each slot 13. A spring 1602 is fixed to the inner wall of the inner cavity 1601. One end of the spring 1602 is fixed with a clamping column 1603. The clamping column 1603 passes through the inner cavity 1601 and is arranged in the limiting baffle 14. The top end of the screw rod 402 is fixed with a connecting column 6. The top end of the connecting column 6 passes through the column 1 and is fixed with a rotating plate 7. An anti-slip sleeve 8 is fixed to the outer wall of the rotating plate 7. The bottom end of the screw rod 402 is rotatably connected to the column 1. The limiting column 405 is fixed in the other column 1. Moving grooves 9 matching the connecting plates 401 are opened at both ends of the two columns 1. Card slots 17 matching the clamping columns 1603 are opened at both ends of the limiting baffle 14. Limiting plates 21 are fixed to both ends of the outer wall of the clamping column 1603. Limiting grooves 22 matching the limiting plates 21 are opened on both sides of each inner cavity 1601 in the support block 12. Driving plates 18 are fixed to both ends of the outer wall of the clamping column 1603. One end of each of the two driving plates 18 passes through the support block 12 and is arranged outside the support block 12. A pulling plate 20 is jointly fixed to the end of each driving plate 18 located outside the support block 12. Driving grooves 19 matching the driving plates 18 are opened on both sides of the inner cavity 1601 in the support block 12. Communication grooves 23 are opened at the bottom ends of the two columns 1. Bottom plates 24 are fixed to the outer walls of the bottom ends of the two columns 1. Mounting holes 25 are opened at the four corners of the two bottom plates 24. Handles 15 are fixed to the top ends of the two limiting baffles 14. Mounting plates 10 are fixed to both ends of the moving plate 2. The two mounting plates 10 are respectively fixed to the two connecting plates 401 through bolts 11. A partition plate 5 is fixed to the inner wall of one of the columns 1 at the center of the screw rod 402. The screw rod 402 passes through the partition plate 5 and is rotatably connected to the partition plate 5.

[0029] The effect achieved by the entire Embodiment 2 is that by the user rotating the rotating plate 7, the connecting column 6 is driven to rotate, thereby driving the screw rod 402 to rotate, so that the two moving plates 2 move towards or away from each other under the combined limitation of the connecting plate 401, the first docking plate 403, the second docking plate 404 and the limiting column 405, so that the distance between the two moving plates 2 can be adjusted, which is convenient for adjustment according to silicon wafers of different lengths and has stronger practicability. When inserting the limiting baffle 14, by the user pulling the two pulling plates 20, the two clamping columns 1603 are driven by the driving plate 18 to contract into the inner cavity 1601. At this time, the user can insert the limiting baffle 14 through the slot 13 bracket. After insertion, by the user releasing the pulling plates 20, the two clamping columns 1603 enter the clamping grooves 17 opened at both ends of the limiting baffle 14 under the reset thrust of the spring 1602 to limit it, achieving the installation effect.

[0030] Working principle: When the device is in use, by the user rotating the rotating plate 7, the connecting column 6 is driven to rotate, thereby driving the screw rod 402 to rotate, so that the two moving plates 2 move towards or away from each other under the combined limitation of the connecting plate 401, the first docking plate 403, the second docking plate 404 and the limiting column 405, so that the distance between the two moving plates 2 can be adjusted, which is convenient for adjustment according to silicon wafers of different lengths. After adjustment, the silicon wafer is clamped between every two shark diamond teeth 3, and then according to the length of the silicon wafer, the limiting baffle 14 is inserted into different slots 13 to limit both ends of the silicon wafer to prevent the silicon wafer from accidentally slipping out. When inserting the limiting baffle 14, by the user pulling the two pulling plates 20, the two clamping columns 1603 are driven by the driving plate 18 to contract into the inner cavity 1601. At this time, the user can insert the limiting baffle 14 through the slot 13 bracket. After insertion, by the user releasing the pulling plates 20, the two clamping columns 1603 enter the clamping grooves 17 opened at both ends of the limiting baffle 14 under the reset thrust of the spring 1602 to limit it, achieving the installation effect.
