The transmission rod 705 is fixedly connected to the top of the support seat 706, and the transmission rod 705 is rotatably connected to the inner wall of the support seat 706. The outer side of the transmission rod 705 is fixedly connected to the front and rear opposite telescopic rods 707. The advantage of this arrangement is that the top ends of multiple positioning frames 710 are fixedly connected to the bottom end of the base plate 1, in order to further improve the stability of the positioning frame 710 and prevent the positioning frame 710 from being offset, and further drive the worm gear 704 to rotate. The middle part of the inner wall of the worm gear 704 is fixedly connected to the transmission rod 705. The worm gear 704 fixes the transmission rod 705, and the rotation of the worm gear 704 drives the transmission rod 705 to rotate, and the rotation of the transmission rod 705 drives the telescopic rod 707 to rotate, and the telescopic rod 707 can be extended and retracted to a certain extent during the rotation process.

[0037] like Figure 1 - Fig. 9 As shown, the reinforcement mechanism 7 also includes a telescopic rod 707, and the telescopic end of the telescopic rod 707 is fixedly connected to an articulated frame 708, and one side of the articulated frame 708 is fixedly connected to a second positioning plate 709. The advantage of this arrangement is that the telescopic rod 707 fixes the articulated frame 708, and at the same time, the telescopic rod 707 drives the articulated frame 708 to move up and down through its own telescopic movement during the rotation process, and one side of the articulated frame 708 is fixedly connected to a second positioning plate 709, and the articulated frame 708 fixes the second positioning plate 709.

[0038] like Figure 1 - Fig. 9As shown, the reinforcement mechanism 7 also includes a second positioning plate 709, which is slidably connected to the inside of the positioning frame 710, and a universal wheel 711 is fixedly connected to the bottom end of the second positioning plate 709. The advantage of this arrangement is that the second positioning plate 709 is driven to slide inside the positioning frame 710 by the movement of the articulated frame 708, and the positioning plate 709 is limited by the positioning frame 710 to prevent the positioning plate 709 from deviating during the movement, thereby further improving its stability. The universal wheel 711 and the positioning plate 2 709 fix the universal wheel 711, and the positioning plate 2 709 moves to drive the universal wheel 711 to move, so that it is retracted into the positioning frame 710, and then connected and reinforced with the contact surface through the storage box 701, thereby increasing the contact area and friction with the contact surface, making the overall structure more stable, and after use, the motor 2 702 can be operated again to extend the universal wheel 711, and then the audit board can be pushed to move to a suitable position for the next use.

[0039] like Figure 1 - Fig. 9 As shown, the lifting mechanism 2 includes a fixed plate 201, a linkage rod 203 is installed at the bottom of the fixed plate 201, a fixed block 207 is fixedly connected to the bottom of the linkage rod 203, a rack is installed on the outer side of the linkage rod 203, a rotating disk 202 is rotatably connected to the outer side of the rack, a circular rotating ring 206 is installed on the outer side of the rotating disk 202, a gear 210 is installed on the outer side of the circular rotating ring 206, a limit block 208 is arranged on the outer side of the gear 210, a coupling block 204 is fixedly connected to the upper end of the limit block 208, a cylinder 209 is installed on the outer side of the gear 210, and the advantage of such a setting is that, through the setting of the lifting mechanism 2, when personnel perform an audit demonstration, they need to use the audit board 4, and the height of the personnel If the degree is not enough, the personnel can rotate the rotating rod 205 to drive the gear 210 to rotate. When the gear 210 rotates, the circular rotating ring 206 fixed on the rear side of the gear 210 can also be driven to rotate together. After the circular rotating ring 206 rotates, it drives the rotating disk 202 to rotate in the same direction, thereby further driving the rack on the outside of the linkage rod 203 to limit the rise on the rotating disk 202. At the same time, when rising, it will also drive the fixed plate 201 to lift or lower the mounting plate 3. At the same time, the limiting groove 213 provided in the square groove 211 on the outside of the rotating disk 202 can limit the rise and fall of the rack, thereby further improving the stability of the device.

[0040] like Figure 1 - Fig. 9As shown, the lifting mechanism 2 also includes a gear 210, and a rotating rod 205 is arranged on the outer side of the gear 210. The rotating rod 205 is used to facilitate personnel to provide driving force for the rotation of the gear 210. The advantage of such a setting is that the rotating rod 205 can facilitate personnel to provide driving force for lifting the audit board 4.

[0041] like Figure 1 - Fig. 9 As shown, the lifting mechanism 2 also includes a square groove 211, a limiting groove 213 is provided inside the square groove 211, and a positioning plate 212 is provided at the bottom of the square groove 211. The advantage of this arrangement is that the use of the positioning plate 212 facilitates the stability of the lifting device.

[0042] like Figure 1 - Fig. 9 As shown, a connecting plate 6 is installed on the outer side of the fixed block 207, a supporting rod 5 is installed on the outer side of the connecting plate 6, an audit plate 4 is installed on the top of the supporting rod 5, and a reinforcing mechanism 7 is installed on the bottom of the connecting plate 6. The advantage of this arrangement is that the stability of the device can be improved through the reinforcing mechanism 7, and the movement of personnel can be facilitated through the reinforcing mechanism.

[0043] like Figure 1 - Fig. 9 As shown, a storage box 701 is provided at the bottom of the base plate 1 , and a support rod 5 is provided at the upper end of the storage box 701 . The advantage of such a configuration is that the universal wheel 711 can be collected and used through the storage box 701 .

[0044] like Figure 1 - Fig. 9 As shown, a spring 8 is provided at the bottom of the support rod 5, and a reinforcing mechanism 7 is provided at the bottom of the spring 8. The advantage of such a configuration is that the provided spring 8 can facilitate the use of the device.

[0045] The technical solution provided by the present invention can solve this problem by rotating the rotating rod 205 when the operator cannot smoothly operate the audit board 4 due to height restrictions during the audit demonstration. The rotation of the rotating rod 205 will drive the gear 210 connected thereto to rotate synchronously. Since a circular rotating ring 206 is fixed to the rear side of the gear 210, the circular rotating ring 206 will be driven to rotate together when the gear 210 rotates. The rotation of the circular rotating ring 206 will then drive the rotating disk 202 to rotate in the same direction. The rotation of the rotating disk 202 will cause the rack on the outside of the linkage rod 203 to limit the rise or fall along the rotating disk 202, and this movement of the rack will drive the fixed plate 201 to lift or lower the mounting plate 3, thereby adjusting the height of the audit board 4 to meet the operator's use requirements. At the same time, the limit groove 213 provided in the square groove 211 on the outside of the rotating disk 202 can effectively limit the rise and fall stroke of the rack, ensuring the stability and accuracy of its movement.

[0046] In order to enhance the stability of the overall structure, the top ends of the plurality of positioning frames 710 are firmly fixed to the bottom end of the base plate 1, which effectively prevents the positioning frames 710 from being offset. When the motor 2 702 starts to operate, it will drive the worm wheel 704 to rotate. The middle part of the inner wall of the worm wheel 704 is fixedly connected to the transmission rod 705, and the rotation of the worm wheel 704 can drive the transmission rod 705 to rotate accordingly. The rotation of the transmission rod 705 further drives the telescopic rod 707 to rotate. The telescopic rod 707 can not only achieve a certain degree of telescopicity during the rotation process, but also plays a role of fixed support for the articulated frame 708. With the rotation and extension of the telescopic rod 707, the articulated frame 708 will be driven to move up and down. One side of the articulated frame 708 is fixedly connected to the positioning plate 2 709. During the movement of the articulated frame 708, the positioning plate 2 709 will slide inside the positioning frame 710, and the positioning frame 710 can limit the positioning plate 2 709 to prevent it from being offset during the movement, thereby further improving the stability of the structure. The bottom end of the second positioning plate 709 is fixedly connected to the universal wheel 711, and the movement of the second positioning plate 709 can drive the universal wheel 711 to perform corresponding movement operations. When the overall structure needs to be more stable, the universal wheel 711 can be retracted into the positioning frame 710, so that the storage box 701 can be directly connected and reinforced with the contact surface, which can increase the contact area and friction with the contact surface and ensure the stability of the overall structure. After the audit demonstration is over, the motor 2 702 is started again to extend the universal wheel 711, and the audit board can be pushed to a suitable position for the next use.

[0047] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
