[0031] Specifically, after the display items are placed on the upper end of the display board 401, the two groups of connecting blocks 1 405 are driven to move by starting the rotating handle 404, and the adjacent sides of the two groups of connecting blocks 1 405 are respectively abutted against the left and right sides of the display items, and then the two groups of connecting blocks 2 408 are driven to move by starting the motor 1 409, and the adjacent sides of the two groups of connecting blocks 2 408 are respectively abutted against the front and back sides of the display items on the upper end of the display board 401, so that the limiting mechanism 4 limits the moving position of the display items placed on the upper end of the display platform 2, thereby avoiding the movement of the items on the upper end of the display board 401 during the rotation of the display platform 2, thereby improving the stability of the display items during the rotating display process.

[0032] like Figure 1 and Figure 2As shown, the protective mechanism 6 includes a fixed rod 602 and a fixed ring 601. The fixed rod 602 is installed on the outer surface of the display platform 2. The outer surface of the fixed rod 602 is slidably connected with the fixed ring 601, and the lower surface of the fixed ring 601 abuts against the upper surface of the transport main board 1; specifically, when the driving mechanism 5 is installed to the lower end of the display platform 2, the fixed ring 601 is pushed to clamp the fixed ring 601 to the outer end of the fixed rod 602, and then the fixed ring 601 is pushed to abut the lower surface of the fixed ring 601 against the upper surface of the transport main board 1, so that the fixed ring 601 shields and protects the driving mechanism 5 at the lower end of the display platform 2, thereby improving the service life of the driving mechanism 5.

[0033] like Figure 1 and Figure 2 As shown, the two sets of heat dissipation mechanisms 7 include a U-shaped fixing plate 701, and the left and right sides of the fixing ring 601 are provided with a card slot, and the two sets of U-shaped fixing plates 701 are respectively installed inside the two sets of card slots of the fixing ring 601, and the two sets of U-shaped fixing plates 701 are installed inside the filter screen 702;

[0034] Specifically, the external air of the fixed ring 601 is guided to the inside of the fixed ring 601 through two groups of filter nets 702, and then the two groups of filter nets 702 are respectively arranged on the left and right sides of the fixed ring 601, so that the air on the left and right sides of the fixed ring 601 can be kept circulating during the use of the fixed ring 601, thereby trying to avoid that the air cannot enter the inside of the protective mechanism 6 when the fixed ring 601 blocks and protects the driving mechanism 5, causing the driving mechanism 5 to be damaged due to overtemperature; the two groups of U-shaped fixing plates 701 are respectively clamped in the two groups of slots of the fixed ring 601, so that the staff can drive the two groups of filter nets 702 to move out of the two groups of slots of the fixed ring 601 by pushing the two groups of U-shaped fixing plates 701, so that the filter nets 702 can be quickly installed and disassembled, thereby reducing the time spent by subsequent staff on cleaning and maintaining the two groups of filter nets 702.

[0035] like Figure 4 and Figure 5As shown, the positioning mechanism 8 includes a limit block 801 and a latch 802. A slot is provided on the side of the fixed rod 602 away from the display platform 2. The limit block 801 is slidably connected to the inside of the slot of the fixed rod 602. A groove is provided on the top of the inner wall of the slot of the fixed rod 602. A limit slider 804 is installed on the upper surface of the limit block 801. The limit slider 804 is slidably connected to the inside of the groove of the fixed rod 602. A spring telescopic rod 803 is installed on the side of the limit block 801 close to the display platform 2. The side of the spring telescopic rod 803 close to the display platform 2 is installed on the inner wall of the fixed rod 602 close to the display platform 2. Through holes are provided on the upper surfaces of the fixed rod 602 and the limit block 801. The latch 802 is inserted into the through holes of the fixed rod 602 and the limit block 801. The lower surface of the limit block 801 abuts against the upper surface of the fixed ring 601.

[0036] Specifically, the lower surface of the limit block 801 abuts against the upper surface of the fixed ring 601, so that the positioning mechanism 8 limits the moving position of the fixed ring 601 at the outer end of the fixed rod 602, thereby avoiding the fixed ring 601 from moving when the fixed ring 601 shields the driving mechanism 5 as much as possible, thereby improving the stability of the fixed ring 601 during use; when the staff is disassembling and moving the fixed ring 601, by pushing the limit block 801, the limit block 801 is moved away Move it from one side of the transport main board 1 to the inside of the card slot of the fixed rod 602, and move the position of the upper end through hole of the limit block 801 to the lower end of the internal through hole of the fixed rod 602, and then push the pin 802 to insert the bottom end of the pin 802 into the through holes of the fixed rod 602 and the limit block 801, so that the moving position of the limit block 801 in the card slot of the fixed rod 602 is limited by the pin 802, thereby avoiding as much as possible that the limit block 801 blocks the staff from normally installing and removing the fixed ring 601 during use.

[0037] At the same time, the movement position of the limit block 801 inside the slot of the fixed rod 602 is limited by the pin 802, so that the staff does not need to manually support and limit the position of the limit block 801 during the installation and removal of the fixed ring 601, thereby reducing the time spent by subsequent staff in installing and removing the fixed ring 601.

[0038] In summary: by starting the electric telescopic rod 504 to push the fixed block 1 505 to move, the fixed block 1 505 is clamped into the inside of the fixed block 2 506, and then by starting the motor 2 503 to drive the fixed block 2 506 and the display platform 2 to rotate synchronously, the device can rotate and exhibit display items during use; by starting the electric telescopic rod 504 to drive the fixed block 1 505 to move, the fixed block 1 505 is moved out of the inside of the fixed block 2 506, and then by pulling the fixed plate 501, the positioning block 502 is moved out of the card slot of the transport main board 1, so that the driving mechanism 5 can be disassembled from between the transport main board 1 and the display platform 2 during use, thereby facilitating subsequent maintenance of the driving mechanism 5 by the staff.

[0039] At the same time, by starting the rotating handle 404, the two groups of connecting blocks 1 405 are driven to move, and the adjacent sides of the two groups of connecting blocks 1 405 are respectively abutted against the left and right sides of the display items, and then by starting the motor 1 409, the two groups of connecting blocks 2 408 are driven to move, and the adjacent sides of the two groups of connecting blocks 2 408 are respectively abutted against the front and back sides of the display items on the upper end of the display board 401, so that the limiting mechanism 4 limits the moving position of the display items placed on the upper end of the display platform 2, thereby avoiding the movement of the items on the upper end of the display board 401 during the rotation of the display platform 2 as much as possible; by pushing the fixed ring 601, the fixed ring 601 is clamped to the outer end of the fixed rod 602, and then by pushing the fixed ring 601, the lower surface of the fixed ring 601 is abutted against the upper surface of the transport main board 1, so that the fixed ring 601 blocks and protects the driving mechanism 5 at the lower end of the display platform 2, thereby improving the service life of the driving mechanism 5.

[0040] In addition, by abutting the lower surface of the limit block 801 against the upper surface of the fixed ring 601, the positioning mechanism 8 limits the moving position of the fixed ring 601 at the outer end of the fixed rod 602, thereby minimizing the movement of the fixed ring 601 when the fixed ring 601 blocks and protects the driving mechanism 5.
