[0034] Example 1

[0035] Reference Figure 1-11 A sampling questionnaire survey auxiliary device includes a support plate 1. A placement groove 101 is formed on the front of the support plate 1. A base block 2 is fixedly connected to the front of the support plate 1 next to the placement groove 101. A top shell 201 is fixedly connected to the top surface of the base block 2. A first shaft support block 4 is fixedly connected to the back of the support plate 1 at one end below the base block 2. A second shaft support block 401 is fixedly connected to the other end of the back of the support plate 1 below the base block 2. The first shaft support block 4 is detachably fixedly connected to a rotating shaft, which rotatably connects to a question-answering component 3. The top surface of the top shell 201 has several sets of marking holes 204 facing downwards. Figure 11 As shown, the answer component 3 can be unfolded. The answer component 3 includes a pre-cut ring 302 corresponding to the marking hole 204, with a steel ball 303 embedded in the center of the pre-cut ring 302. The second shaft support block 401 is rotatably connected to a hollow shaft 404, which is engaged with a clamping post 402. It should be noted that both ends of the clamping post 402 are fixed with levers. During use, the clamping post 402 can be disengaged from the hollow shaft 404 by turning the levers. When using this device, one end of the answer component 3 is passed through the first through-hole 105 near the answer component 3 and then laid on the column wheel 103. At this time, the answer component 3... The steel ball 303 is placed in the concave annular groove 104, which avoids the steel ball 303 being squeezed by the surface of the column wheel 103 when the answer component 3 slides on the column wheel 103, thus improving the smoothness and safety of the answer component 3 when sliding. The answer component 3 passes through the top shell 201 through the second through narrow opening, then through the column wheel 103 placed at the other end of the support plate 1, the first through narrow opening 105, and finally is placed on the inner wall of the clamping column 402. Then, the lever ring is turned to clamp the clamping column 402 and one end of the answer component 3 onto the hollow shaft 404, thus realizing the updating and collection of the answer component 3. The top shell 201 is equipped with a marking mechanism.

[0036] The marking mechanism includes a pressing column 701 slidably connected to the inner wall of a marking hole 204 located on the top surface of the top housing 201. A base block 702 is fixedly connected to the bottom end of the pressing column 701. First springs 703 are fixedly connected to both ends of the top surface of the base block 702. The pressing column 701 is located at the center of the top surface of the base block 702. A column blade 7 is fixedly connected to the center of the bottom surface of the base block 702. The end of the first spring 703 furthest from the base block 702 is fixedly connected to the inner top surface of the top housing 201. The bottom end of the blade 7 is provided with a ring-shaped blade. The outer diameter of the blade 7 is smaller than the diameter of the marking hole 204. The back of the support plate 1 is detachably fixedly connected to the shaft 203 at the center of each group of marking holes 204. The shaft 203 is rotatably connected to the collection mechanism. It should be noted that the detachability of the shaft 203 allows the collection mechanism rotatably connected to the shaft 203 to be removed, which facilitates the intuitive display of the distribution of each option in the questionnaire survey and greatly improves the accuracy of data analysis after the questionnaire survey.

[0037] It should be further explained that the support plate 1 is fixedly connected to the limiting plate at the top of the placement slot 101. The limiting plate facilitates the fixation of the questionnaire placed in the placement slot 101. Through the setup of the support plate 1, placement slot 101, and marking mechanism, the entire sampling questionnaire survey can be completed with just one questionnaire, greatly saving paper, avoiding waste, and making the device more environmentally friendly. At the same time, it achieves dual verification. Users can both check the used answer components 3 to count the distribution of options for each question in the sampling questionnaire survey, and determine the option distribution by counting the number of pre-cut rings 302 that are cut off by the column cutter 7 and then released from the answer component 3 under the gravity of the steel ball 303. This greatly enhances the accuracy of the sampling questionnaire survey. The structure is ingenious, efficient, easy to operate, and suitable for promotion. The support plate 1 has a base 102 fixedly connected to both ends of its back side. The top shell 201 is hollow inside. The top surface of the top shell 201 has a calibration port 202 at both ends. The answer component 3 is provided with several calibration blocks 301. The calibration port 202 and the calibration block 301 enable the answer component 3 to more accurately align the pre-cut ring 302 with the corresponding column knife 7 during use. The hollow shaft 404 extends out of the second shaft support block 401 and is fitted with a rotating handle 405. The marking hole 204 passes through the top shell 201, the bottom block 2, and the support plate 1. The front of the support plate 1 is provided with a first through narrow opening 105 above the first shaft support block 4 and the second shaft support block 401. The top shell 201 is provided with a second through narrow opening at both ends facing the first shaft support block 4 and the second shaft support block 401. The front of the support plate 1 is provided with a pulley mechanism at both of the first through narrow openings 105.

[0038] The pulley mechanism includes a column wheel 103 with two side blocks rotatably connected between the two side blocks. The column wheel 103 is provided with a concave annular groove 104. The pulley mechanism can not only change the direction of operation of the answer component 3, but also ensure that when the answer component 3 slides on the column wheel 103, the steel ball 303 embedded inside the answer component 3 is always placed in the concave annular groove 104, thereby realizing the positioning of the movement trajectory of the answer component 3 and greatly improving the smoothness and stability of the operation of the device.

[0039] The collection mechanism includes a turntable 205 rotatably connected to a shaft 203. Multiple column boxes 206 are fixedly connected at equal intervals along the side edge of the turntable 205. The column boxes 206 are preferably made of transparent material, such as transparent plastic, so that users can intuitively understand the approximate distribution of each question and option in the questionnaire without disassembling the collection mechanism. This allows the operator to quickly obtain the required approximate conclusions without needing to accurately statistically analyze the results of the sampling questionnaire survey, greatly improving the efficiency of the sampling questionnaire survey. The column boxes 206 slide against the back of the support plate 1. The interior of the column boxes 206 is hollow. The side of the column box 206 that slides against the support plate 1 is open. A pinion 207 is fixedly connected to the side of the column box 206 away from the support plate 1. The pinion 207 meshes with an internal toothed belt 601.

[0040] Example 2

[0041] Reference Figure 9 As shown, there are eight column boxes 206. This arrangement means that when the questionnaire placed in the placement slot 101 includes the second page, the column box 206 corresponding to the marking hole 204 needs to be replaced. At this time, multiple collection mechanisms can be controlled simultaneously by simply pulling the internal toothed belt 601, which greatly increases the application range of this device and makes it suitable for questionnaires with more questions. The structure is ingenious and easy to use. The multiple column boxes 206 can also be used when a question has more than four options. The number of column boxes 206 can be adjusted according to actual needs.

[0042] Reference Figure 7 , Figure 8 and Figure 10As shown, the hollow shaft 404 is rotatably connected to both ends of the second shaft support block 401 with grooved wheels 403. The interior of the hollow shaft 404 is hollow, and a control column 503 is slidably connected to the inner wall of the hollow shaft 404. Two magnets 504 are embedded in the control column 503. An adjustment mechanism is provided inside the grooved wheel 403. The adjustment mechanism includes a snap-fit ​​cavity 5 provided inside the grooved wheel 403. The hollow shaft 404 has a snap-fit ​​interface at the grooved wheel 403. The snap-fit ​​cavity 5 penetrates the grooved wheel 403 inward. A second spring 501 is fixedly connected to the inner top of the snap-fit ​​cavity 5 away from the hollow shaft 404. A snap-fit ​​iron block 502 is fixedly connected to one end of the second spring 501 near the hollow shaft 404. A pull rope 6 is fixedly connected inside the groove of the grooved wheel 403. The other end of the pull rope 6 away from the grooved wheel 403 is fixedly connected to the outer side of the inner toothed belt 601.

[0043] The control mechanism utilizes the controllable sliding of the control column 503 within the hollow shaft 404. When the magnet 504 embedded at one end of the control column 503 slides to the corresponding card interface, the card-attaching iron block 502 within the card-attaching cavity 5 is attracted to the inner wall of the card interface by the magnet 504. At this time, the grooved wheel 403 corresponding to the card interface will lock with the hollow shaft 404. When the operator rotates the hollow shaft 404 by turning the handle 405 to collect the used answer component 3, the grooved wheel 403 will rotate, thereby tightening the pull rope 6 located on one side of the internal toothed belt 601, thus driving all collection mechanisms to rotate. This allows for the replacement of different column boxes 206, and when it is necessary to restore the column box 206... In the initial position of 06, simply slide the magnet 504 at the other end of the control column 503 to another corresponding card interface. At this time, the previous magnet 504 slides out of its corresponding card interface, which can lock the other grooved wheel 403 with the hollow shaft 404. When the operator rotates the hollow shaft 404 by turning the handle 405 to collect the used answer component 3, it can drive the grooved wheel 403 to rotate, thereby tightening the pull rope 6 located on the other side of the internal toothed belt 601, thereby driving all collection mechanisms to rotate and return to their original positions. Through the above ingenious design, the automation level of this device is greatly improved, making it easy to operate and use, and greatly improving the work efficiency of sampling questionnaire surveys, making it suitable for promotion.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
