[0025] The splicing mechanism 6 comprises two accommodating grooves 601, the accommodating grooves 601 provide mounting spaces, the two accommodating grooves 601 are respectively arranged in the inner part of the two ends of one of the splicing half rings 1, the inner part of the accommodating groove 601 is provided with a locking spring 602, the inner part of the accommodating groove 601 is slidably connected with a limiting ring 603, the limiting ring 603 has a limiting effect, and the limiting ring 603 can be reset by the locking spring 602, the middle part of the limiting ring 603 is fixedly connected with a plug rod 604, the inner part of the two ends of one of the splicing half rings 1 is provided with a plug groove 605, the two ends of the other splicing half ring 1 are fixedly connected with a plug block 606, the plug block 606 can be inserted into the inner part of the plug groove 605, so that the preliminary splicing of the two splicing half rings 1 can be completed, the top of the plug block 606 is provided with a plug hole 607, after the plug rod 604 is inserted into the inner part of the plug hole 607, the plug block 606 can be prevented from moving out of the inner part of the plug groove 605, so that the splicing of the two splicing half rings 1 can be completed, the plug rod 604 is clamped with the plug hole 607, the plug block 606 is inserted into the inner part of the plug groove 605, one end of the locking spring 602 is fixedly connected to the inner wall of the accommodating groove 601, the other end of the locking spring 602 is fixedly connected to the top of the limiting ring 603, the top of the plug rod 604 is fixedly connected with a pull handle 608, the pull handle 608 can conveniently pull the plug rod 604 upward, when the two splicing half rings 1 are spliced, first, the two splicing half rings 1 are sleeved on the outer part of the navel orange seedlings, then the pull handle 608 is pulled upward, so that the plug rod 604 can be moved upward, the limiting ring 603 can be moved upward and the locking spring 602 can be compressed, after the bottom of the plug rod 604 moves out of the inner part of the plug groove 605, the plug block 606 is inserted into the inner part of the plug groove 605, at this time, the pull handle 608 is released, under the action of the reaction force of the locking spring 602, the limiting ring 603 can be moved downward, so that the plug rod 604 can be moved downward, then the bottom of the plug rod 604 can be inserted into the inner part of the plug hole 607, so that the plug block 606 can be prevented from moving out of the inner part of the plug groove 605, so that the two splicing half rings 1 are sleeved on the outer part of the navel orange seedlings.

[0026] Working principle: when the two splicing half rings 1 are spliced, first, the two splicing half rings 1 are sleeved on the outer part of the navel orange seedlings, then the pull handle 608 is pulled upward, so that the plug rod 604 can be moved upward, the limiting ring 603 can be moved upward and the locking spring 602 can be compressed, after the bottom of the plug rod 604 moves out of the inner part of the plug groove 605, the plug block 606 is inserted into the inner part of the plug groove 605, at this time, the pull handle 608 is released, under the action of the reaction force of the locking spring 602, the limiting ring 603 can be moved downward, so that the plug rod 604 can be moved downward, then the bottom of the plug rod 604 can be inserted into the inner part of the plug hole 607, so that the plug block 606 can be prevented from moving out of the inner part of the plug groove 605, so that the two splicing half rings 1 are sleeved on the outer part of the navel orange seedlings; When adjusting the height of the seedling straightener, first release the locking mechanism 4, which allows the extension rod 303 to be pulled downwards, thereby driving the limit piston 302 to move downwards. At this time, external gas enters through the exhaust port 313, preventing the limit piston 302 from being unable to move downwards due to air pressure. After the extension rod 303 extends, the positioning mechanism 4 locks the extension rod 303, thus completing the height adjustment. When the limit piston 302 moves downwards, the gas inside the outer cylinder 301 is forced into the automatic valve 310 through the vent pipe 305. At this time, the automatic valve 310 is opened, allowing gas to enter the vent groove 311 and evenly enter the pressing airbag 2 through the connecting hole 312, thereby causing the pressing airbag 2 to inflate and press against the navel orange seedling. On the outer wall of the seedling, the automatic valve 310 is closed at this time, so as to maintain the air pressure inside the airbag 2. When the extension rod 303 is retracted into the outer cylinder 301, the outer cylinder 301 will suck in air, and the suction force will be transmitted to the automatic valve 310 through the vent pipe 305. At this time, due to the closure of the automatic valve 310, the gas inside the airbag 2 cannot enter the automatic valve 310. The vent plate 308 is sucked towards the automatic valve 310 under the action of suction. When the vent hole 309 on the vent plate 308 is no longer blocked by the fixed cylinder 306, the outside gas will enter the fixed cylinder 306 through the vent hole 309, and then enter the automatic valve 310 through the fixed cylinder 306. It will then enter the outer cylinder 301 through the vent pipe 305, and thus not hinder the extension rod 303 from retracting into the outer cylinder 301. When the extension rod 303 needs to be extended or retracted into the outer cylinder 301, the sliding ring 403 is pulled towards the fixed ring 401, which compresses the push spring 402. The sliding ring 403 then drives the push rod 404 to move towards the fixed ring 401, causing the middle part of the clamping jaw 405 to rotate towards the fixed ring 401. This causes the clamping half-turn 406 to open towards both sides of the extension rod 303, allowing the extension rod 303 to be extended or retracted into the outer cylinder 301. After the extension rod 303 is extended or retracted, the sliding ring 403 is released, and the push spring... Under the reaction force of 402, the sliding ring 403 moves towards the fixed ring 401, which in turn moves the push-pull rod 404 away from the fixed ring 401. This causes the clamping claw 405 to rotate downwards, which in turn causes the clamping half-turn 406 to rotate towards the extension rod 303. The clamping half-turn 406 clamps the extension rod 303. Because the elastic coefficient of the push spring 402 is large, the clamping half-turn 406 clamps the extension rod 303 with a large force, which prevents the extension rod 303 from retracting into or extending out of the outer cylinder 301. When the gas inside the abutting air bag 2 is too much or as the navel orange seedling grows and becomes thicker, the excessive gas will enter the inside of the mounting cylinder 501 through the communication hole 312 and the ventilation groove 311, then push the limiting ring 504 to move away from the spliced half ring 1, so as to drive the ventilation cylinder 505 to move away from the spliced half ring 1, when the air vent hole 506 on the ventilation cylinder 505 moves out of the outside of the mounting cylinder 501, the excessive gas inside the abutting air bag 2 will be discharged through the ventilation cylinder 505 and the air vent hole 506, when the excessive gas inside the abutting air bag 2 is discharged, the limiting ring 504 can be driven to move towards the spliced half ring 1 under the action of the counterforce of the pushing spring 503, and the ventilation cylinder 505 can be driven to retract into the inside of the mounting cylinder 501, then the air vent hole 506 can be blocked by the mounting cylinder 501, so as to prevent the gas inside the abutting air bag 2 from continuing to be discharged, thus the abutting air bag 2 can always abut against the trunk of the navel orange seedling, and since it is a flexible contact with the trunk of the navel orange seedling, as the navel orange seedling grows and becomes thicker, the abutting air bag 2 can automatically adjust the degree of inflation, thus realizing the fixation and righting of the navel orange seedling without the need to adjust the diameter of the seedling trunk clamped by the righting device as the seedling grows and becomes thicker.

[0027] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
