[0032] Principle and advantages: in the design of the device, by setting the limiting mechanism 3, when it is necessary to adjust the transverse movement of the support rod 4 during use, the sliding block 2 in the adjusting guide rail 1 can be slid to achieve this purpose, the specific operation process is as follows: during adjustment, only need to gently pull the bridge handrail 38, drive the connecting shaft 37 to move upwards, the connecting shaft 37 moving upwards will push the bottom plate 35 to move upwards, at this time, the bottom plate 35 will extrude the limiting spring 34, so as to make the limiting spring 34 contract, with the bottom plate 35 moving upwards, the limiting pin 36 on the bottom plate 35 will be separated from the limiting hole 32, after the limiting pin 36 and the limiting hole 32 are separated from each other, the sliding block 2 can move freely, so as to realize the adjustment of the transverse position of the support rod 4, when adjusted to the appropriate position, release the bridge handrail 38, the limiting spring 34 will drive the bottom plate 35 to move downwards by virtue of its own reset characteristics, at this time, the limiting pin 36 at the bottom of the bottom plate 35 will be inserted into the inner side of the limiting hole 32 again, through the mutual clamping and limiting of the limiting pin 36 and the limiting hole 32, the fixation of the sliding block 2 is realized, since the sliding block 2 is connected with the support rod 4, the support rod 4 can be stably fixed in this way, this design enables the device to flexibly adjust the position of the support rod 4 according to the actual demand during use, and can be reliably fixed after adjustment is completed, which improves the operability and stability of the whole device;

[0033] By setting the hinge mechanism 5, the swing adjustment of the two support rods 4 can be achieved by adjusting the rotation of the gear 53 during use. When it is necessary to fix the support rod 4 in a specific position, the insertion rod 7 can be inserted into the ground to achieve the insertion and installation of the support rod 4. This method makes the device very convenient in practical applications. During the adjustment process, a series of operations are achieved by pulling the bridge handrail 38 upward. When the bridge handrail 38 moves upward, it will drive the base plate 35 upward. At this time, the upper guide block 521 on the base plate 35 will separate from the lower guide block 524. In this case, the telescopic spring 522 will return to its original position, thereby causing the limiting tooth 525 to separate from the gear 53. At this time, the rotation angle of the support rod 4 can be easily adjusted to meet different usage requirements. After adjustment, the bridge handrail 38 is released, and the limiting spring 34 will reset and drive the base plate 35 to move down. Since the elastic force of the limiting spring 34 is greater than that of the telescopic spring 522, when the base plate 35 moves down, it will squeeze the lower guide block 524 through the upper guide block 521, causing the lower guide block 524 to drive the slide plate 523 to move inward. After the slide plate 523 moves inward, the limiting tooth 525 on the slide plate 523 will limit each other with the gear 53, thereby achieving quick fixation of the two support rods 4. It can be seen that the setting of the limiting mechanism 3 adopted by this device can not only meet the adjustment requirements of the support rods 4 at different angles, but also quickly achieve stable fixation after adjustment, which greatly improves the stability and convenience during use, and provides users with efficient and reliable protection in actual operation.

[0034] By setting up the clamping mechanism 6, the height of the clamping mechanism 6 can be adjusted according to actual needs by adjusting the slider 62 inside the adjustment groove 61 during use. After the height is adjusted, the hand screw 64 can be turned to abut the support rod 4, thereby fixing the side rail 65. This method allows users to flexibly adjust the height of the clamping mechanism 6 according to different scenarios and the growth of tomato plants to achieve the best use effect. After the height is adjusted, the screw 66 can also be rotated by turning the adjustment handle 67. Since the threads at both ends of the screw 66 turn in opposite directions, when the screw 66 rotates, it can drive the movable block 68 to slide. At this time, the movable block 68 will drive the clamping plates 69 to move relative to each other, thereby achieving auxiliary clamping and fixing of the tomato roots. This design of the clamping mechanism 6 can closely fit the growth needs of the tomato plant, not only ensuring the stability of the tomato plant during the growth process, but also flexibly adjusting according to the growth changes of the plant, improving the convenience and flexibility of the device in actual use, and providing strong support for the healthy growth of tomatoes.
