[0021] The technical solutions of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figures 1 to 3 As shown, a device for collecting and printing wrong questions includes a thermal printer 1 and a fixed bracket 2. The fixed bracket 2 includes a top plate 21, a side plate 22, and a bottom plate 23. The side plate 22 is connected to one end of the bottom plate 23 and is located on the outside of the bottom plate 23. The top plate 21 is connected to the other end of the side plate 22 and is located on the inside of the side plate 22. The thermal printer 1 is movably connected to the top plate 21. A viewfinder 231 is provided through the bottom plate 23. The thermal printer 1 is provided with a camera assembly 3. The present invention movably connects the thermal printer 1 above the fixed bracket 2, and the thermal printer 1 is provided with a camera assembly 3. Compared with traditional wrong question collection equipment that requires a combination of multiple devices such as a camera, a printer, and a mobile phone to collect, shoot, and print, the present invention only requires a thermal printer 1 and a fixed bracket 2, which can effectively save costs. In addition, when shooting with a handheld camera or a mobile phone, there will be shaking, resulting in tilted and blurred pictures. However, using a fixed bracket 2 can locate the photo area, achieving a better shooting effect.

[0023] When in use, the thermal printer 1 is snapped onto the top plate 21, and the bottom plate 23 is placed above the file to be collected. The range to be photographed can be framed by the viewfinder 231, and the camera component can take pictures of right or wrong questions, and transmit the photographed images to the thermal printer 1 for printing.

[0024] The thermal printer 1 is provided with a connecting convex shell 11 on one end face, and a limiting frame 211 adapted to the convex shell is opened through the top plate 21. The connecting convex shell 11 is movably connected to the limiting frame 211, and buckles 4 are symmetrically provided on both sides of the limiting frame 211. The connecting convex shell 11 is provided with a buckle groove 5 at a position corresponding to the buckle 4. When the buckle 4 is clamped and fixed with the buckle groove 5, the thermal printer 1 is fixedly connected to the top plate 21. When the thermal printer 1 needs to be used for taking pictures and printing, the thermal printer 1 is placed on the top plate 21 so that the connecting convex shell 11 passes through the limiting frame 211 on the top plate 21. At this time, the buckle 4 is clamped and fixed with the buckle groove 5, so that the wrong questions can be taken more clearly within the set distance. The wrong question collection and printing functions can be realized without using mobile phones, computers and other electronic devices. It is more convenient to use and can truly achieve mobile phone-free homework. Parents no longer need to monitor the use of mobile phones.

[0025] The camera assembly 3 is arranged on the connecting convex shell 11. The camera assembly 3 includes a camera 31 and a rectangular light-shielding port 32. The rectangular light-shielding port 32 is opened on the connecting convex shell 11. The camera 31 is embedded in the rectangular light-shielding port 32. The rectangular light-shielding port 32 can improve the uniformity of light at the shooting and collection position and cover the range that is unnecessary to be collected.

[0026] The top plate 21, side plate 22 and bottom plate 23 are integrally formed, which simplifies the structure of the fixing bracket 2, reduces the manufacturing difficulty, reduces the production cost, is easy to assemble with the thermal printer 1, and can be easily replaced in time if damaged, without affecting the use of the thermal printer 1.

[0027] The length of the viewfinder 231 is 160 mm to 190 mm, the width of the viewfinder 231 is 50 mm to 120 mm, the distance between the top plate 21 and the bottom plate 23 is 130 mm to 150 mm, and the side plate 22 is inclined at 45 to 60 degrees from the horizontal. As the optimal solution, in this embodiment, the length of the viewfinder 231 is 170 mm, the width is 60 mm, and the distance between the top plate 21 and the bottom plate 23 is 135 mm.

[0028] From the above description of the present invention, it can be seen that compared with the prior art, the present invention provides a wrong question collection and printing device, which is provided with a fixed bracket that can be used to fix the thermal printer, thereby positioning the focal length of the photo, so as to quickly collect the photo content, and can also indicate the photo collection area, that is, the viewfinder area is the collection area, which effectively avoids the influence of handheld cameras or mobile phones on the wrong question collection effect, makes the collected wrong question pictures clearer, and then prints them out with better effect through thermal printers; adding a camera component to the traditional wrong question printer can collect data, avoiding the traditional wrong question printer's dependence on mobile phones. Students only need to buy a combination of a wrong question printer with a camera and a fixed bracket to complete a simple wrong question collection action, which reduces the purchase cost. Compared with the traditional wrong question printer, it truly achieves mobile phone-free homework, and parents no longer need to monitor the use of mobile phones.
