Groove 303, the mounting structure 6 includes a mounting ring 601 fixedly connected to the placement tube 1 and two mounting blocks 602 slidably connected to the connecting sleeve 7, the mounting ring 601 and the connecting sleeve 7 are detachably connected, the mounting block 602 is engaged with the mounting ring 601, the cross-section of the mounting block 602 is a trapezoidal structure, a spring 603 is fixedly connected between the mounting block 602 and the connecting sleeve 7, a drive shaft 604 is rotatably connected in the mounting block 602, a drive ring 605 is rotatably connected in the connecting sleeve 7, and the drive shaft 604 and the drive ring 605 are rollingly matched.

[0039] Specifically, such as Figure 1 、 Figure 2 、 Figure 5 and Figure 14As shown, the protective door 302 is fixedly connected to a fixing plate 304, and the placement tube 1 is fixedly connected to two connecting blocks 305, and a guide rail 306 is fixedly connected between the two connecting blocks 305. A card plate 307 is slidably connected to the guide rail 306, and the card plate 307 is slidably connected to the placement tube 1. A first knob 309 is threadedly connected to the fixing plate 304, and the card plate 307 conflicts with the first knob 309. A pull block 308 is fixedly connected to the card plate 307. At this time, a card with identification information is placed in the placement slot 303, and then the protective door 302 is rotated through the rotating shaft 301. When it is rotated to a certain angle, by pulling the pull block 308 upward, the pull block 308 moves upward, driving the card plate 307 to move upward, and the card plate 307 will slide with the guide rail 306. At the same time, when the card plate 307 moves upward to a certain position, the protective door 302 is rotated to be parallel to the placement tube 1, and then the card plate 307 is released, so that the card plate 307 contacts the first knob 309. At this time, by rotating the first knob 309, the first knob 309 is threadedly engaged with the fixing plate 304, and the first knob 309 is pressed against the card plate 307, so that the fixing effect of the protective door 302 is better, and the protective door 302 is prevented from rotating.

[0040] Specifically, such as Figure 1 、 Figure 8 、 Figure 10 and Figure 11As shown, a connecting plate 606 is fixedly connected to the driving ring 605, and the connecting plate 606 is slidably connected to the connecting sleeve 7. A second knob 607 is threadedly connected to the connecting plate 606, and the second knob 607 conflicts with the connecting sleeve 7. When assembling between the placing cylinder 1 and the connecting sleeve 7, the placing cylinder 1 and the connecting sleeve 7 are plugged in, and the mounting groove on the mounting ring 601 corresponds to the mounting block 602. When the mounting ring 601 conflicts with the inclined surface of the mounting block 602, the mounting block 602 will slide into the connecting sleeve 7, and the spring 603 will contract during sliding. When the mounting ring 601 and the connecting sleeve 7 slide to a certain position, the mounting block 602 is engaged with the mounting groove on the mounting ring 601 under the action of the spring 603. When installing between the placing cylinder 1 and the connecting sleeve 7 , the two mounting blocks 602 automatically engage with the mounting ring 601, which is convenient for quick installation. At the same time, the mounting block 602 engages with the mounting ring 601, which improves the stability between the placement tube 1 and the connecting sleeve 7. When disassembly is required, the driving ring 605 is driven to rotate by the connecting plate 606. When the driving ring 605 rotates, the driving shaft 604 will roll with the inclined surface on the driving ring 605, so that the driving ring 605 resists the movement of the driving shaft 604. When the driving shaft 604 moves, it drives the mounting block 602 to shrink into the connecting sleeve 7, and then by rotating the second knob 607, the second knob 607 will be threadedly engaged with the connecting plate 606 when it rotates. The second knob 607 will press against the connecting sleeve 7 to prevent the driving ring 605 from rotating. At this time, the placement tube 1 and the connecting sleeve 7 can be disassembled.

[0041] Specifically, such as Figure 1 、 Figure 5 、 Figure 8 、 Figure 9 and Figure 13As shown, the fixing structure 2 includes a fixing cone 201 slidably connected to the placement cylinder 1 and rotatably connected to the fixing screw 202 in the placement cylinder 1, the fixing cone 201 is threadedly connected to the fixing screw 202, a fixing block 204 is fixedly connected to the fixing cone 201, the fixing block 204 is slidably connected to the placement cylinder 1, a guide rod 205 is fixedly connected to the placement cylinder 1, the fixing block 204 is slidably connected to the guide rod 205, the top of the fixing screw 202 is fixedly connected to the hand wheel 203, and when the adjustment of the support leg 408 is completed, the fixing screw 202 is rotated by the hand wheel 203 to fix When the screw 202 rotates, it cooperates with the thread of the fixing cone 201. The fixing cone 201 will drive the fixing block 204 to slide in the placement tube 1. The fixing cone 201 will extend out of the bottom of the placement tube 1. At the same time, the fixing block 204 will slide with the guide rod 205. The setting of the guide rod 205 makes the movement of the fixing block 204 more stable. At the same time, when the fixing cone 201 is extended to a certain distance, the fixing cone 201 can be inserted into the soil. By inserting the fixing cone 201 into the soil, the stability of the placement tube 1 can be improved. At the same time, the setting of the fixing cone 201 prevents mud and sand from adhering to the fixing screw 202 and damaging the thread of the fixing screw 202.

[0042] Specifically, such as Figure 1 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 and Figure 12As shown, the support structure 4 includes three mounting seats 401 fixedly connected to the bottom of the connecting sleeve 7 and a mounting shaft 402 rotatably connected to the mounting seat 401, a mounting rod 403 is fixedly connected to the mounting shaft 402, a driving sleeve 406 is rotatably connected to the mounting rod 403, a support leg 408 is slidably connected to the driving sleeve 406, a screw rod 404 is fixedly connected to the support leg 408, a threaded ring 407 is fixedly connected to the driving sleeve 406, the screw rod 404 is threadedly connected to the threaded ring 407, a guide block 405 is fixedly connected to the screw rod 404, the guide block 405 is slidably connected to the mounting rod 403, and the driving The bottom of the sleeve 406 is fixedly connected to a rotating block 409, and the limiting structure 5 includes a slider 501 slidably connected to the mounting rod 403 and a connecting column 502 fixedly connected to the slider 501. The connecting column 502 is fixedly connected to a limiting block 503, and the limiting block 503 is engaged with the mounting shaft 402. The slider 501 is fixedly connected to an anti-slip block 505, and the anti-slip block 505 is slidably connected to the mounting rod 403. A tension spring 504 is fixedly connected between the slider 501 and the mounting rod 403. The bottom of the slider 501 is fixedly connected to a pull plate 506. When in use, first put the three legs 408 in contact with the ground. When encountering uneven When the ground is uneven, the driving sleeve 406 is driven to rotate by the rotating block 409, and the driving sleeve 406 rotates, which drives the threaded ring 407 to rotate. When the threaded ring 407 rotates, it cooperates with the screw rod 404 thread, and the screw rod 404 drives the support leg 408 and the driving sleeve 406 to slide through the guide block 405. At the same time, the support leg 408 and the driving sleeve 406 slide, and the length of the driving sleeve 406 extended by each support leg 408 can be adjusted, so that each support leg 408 can be in contact with the ground on an uneven ground, thereby improving the stability of the connecting sleeve 7. When the angle of the mounting rod 403 needs to be adjusted, the pull plate 506 is pulled, and the pull plate 506 drives the slider 501 and the mounting rod 403. When the mounting rod 403 slides and the slider 501 moves, the tension spring 504 contracts, and at the same time drives the anti-slip block 505 to slide, and the slider 501 will drive the connecting column 502 to move. When the connecting column 502 moves, it drives the limit block 503 to move, so that the limit block 503 is no longer engaged with the mounting shaft 402. At this time, the angle of the support leg 408 can be adjusted by rotating the mounting shaft 402 and the mounting rod 403. The angle of the support leg 408 can be adjusted according to the installation position of the placement tube 1 to ensure the level and stability of the placement tube 1. After the adjustment is completed, release the pull plate 506 to engage the limit block 503 with the mounting shaft 402 to limit and fix the mounting shaft 402.

[0043] When the present invention is in use, when assembling between the placing tube 1 and the connecting sleeve 7, the placing tube 1 and the connecting sleeve 7 are plugged in, and the mounting groove on the mounting ring 601 is made to correspond to the mounting block 602. When the mounting ring 601 and the inclined surface of the mounting block 602 collide with each other, the mounting block 602 will slide into the connecting sleeve 7. When sliding, the spring 603 contracts. When the mounting ring 601 and the connecting sleeve 7 slide to a certain position, the mounting block 602 is engaged with the mounting groove on the mounting ring 601 under the action of the spring 603. When installing between the placing tube 1 and the connecting sleeve 7, the two mounting blocks 602 are automatically engaged with the mounting ring 601, which is convenient for quick installation. The mounting block 602 is engaged with the mounting ring 601, which improves the stability between the placement tube 1 and the connecting sleeve 7. When disassembly is required, the driving ring 605 is driven to rotate by the connecting plate 606. When the driving ring 605 rotates, the driving shaft 604 rolls with the inclined surface on the driving ring 605, so that the driving ring 605 moves against the driving shaft 604. When the driving shaft 604 moves, the mounting block 602 is retracted into the connecting sleeve 7. Then, by rotating the second knob 607, the second knob 607 is threadedly engaged with the connecting plate 606 when it is rotated. The second knob 607 is pressed against the connecting sleeve 7 to prevent the driving ring 605 from rotating. At this time, the placement tube 1 and the connecting sleeve 7 can be disassembled.

[0044] When in use, first make the three legs 408 contact with the ground. When encountering uneven ground, the driving sleeve 406 is driven to rotate by the rotating block 409. When the driving sleeve 406 rotates, the threaded ring 407 is driven to rotate. When the threaded ring 407 rotates, it is threadedly matched with the screw rod 404. The screw rod 404 will drive the legs 408 and the driving sleeve 406 to slide through the guide block 405. At the same time, the legs 408 and the driving sleeve 406 slide. The length of the driving sleeve 406 extended by each leg 408 can be adjusted, so that each leg 408 can be in contact with the ground on uneven ground, thereby improving the stability of the connecting sleeve 7. When it is necessary to adjust the angle of the mounting rod 403, the pull plate 506 is pulled to When the slider 501 is moved, the tension spring 504 contracts, and the anti-drop block 505 is driven to slide. The slider 501 drives the connecting post 502 to move. When the connecting post 502 moves, the limit block 503 is driven to move, so that the limit block 503 is no longer engaged with the installation shaft 402. At this time, the angle of the support leg 408 can be adjusted by rotating the installation shaft 402 and the installation rod 403. The angle of the support leg 408 can be adjusted according to the installation position of the placement tube 1 to ensure the level and stability of the placement tube 1. After the adjustment is completed, the pull plate 506 is released to make the limit block 503 engage with the installation shaft 402, and the installation shaft 402 is fixed;

[0045] At the same time, when the adjustment of the support legs 408 is completed, the fixing screw 202 is rotated by the hand wheel 203. When the fixing screw 202 rotates, it cooperates with the thread of the fixing cone 201. The fixing cone 201 will drive the fixing block 204 to slide in the placement tube 1, and the fixing cone 201 will extend out of the bottom of the placement tube 1. At the same time, the fixing block 204 will slide with the guide rod 205. The setting of the guide rod 205 makes the movement of the fixing block 204 more stable. At the same time, when the fixing cone 201 is extended to a certain distance, the fixing cone 201 can be inserted into the soil. By the fixing cone 201 being inserted into the soil, the stability of the placement tube 1 can be improved. At the same time, the setting of the fixing cone 201 prevents mud and sand from adhering to the fixing screw 202 and damaging the thread of the fixing screw 202.

[0046] At this time, place the card with the identification information into the placement slot 303, and then rotate the protective door 302 through the rotating shaft 301. When it is rotated to a certain angle, pull the pull block 308 upward. When the pull block 308 moves upward, it drives the card plate 307 to move upward. The card plate 307 will slide with the guide rail 306. At the same time, when the card plate 307 moves upward to a certain position, the protective door 302 is rotated to be parallel to the placement tube 1, and then the card plate 307 is released, so that the card plate 307 contacts the first knob 309. At this time, by rotating the first knob 309, the first knob 309 is threadedly engaged with the fixing plate 304, and the first knob 309 is pressed against the card plate 307, so that the fixing effect of the protective door 302 is better, and the protective door 302 is prevented from rotating.
