If a gap occurs, it will cause rust on the gap surface or hole surface where the position is welded later; the middle adjustable disc member 24 includes a middle disc body 241 and a middle adjustable component. The middle adjustable component includes a movable connecting disc 242. The movable connecting disc 242 is slidably connected to the connecting disc On the round rod 26, the movable connecting disk 242 is provided with a hinged connecting end 243, a push rod connecting end and a guide connecting column hole, the hinged connecting end 243 is provided with a connecting ring seat 244, there are more than six connecting ring seats 244, each connecting ring seat 244 is distributed in a circular shape to form a hexagonal connecting ring seat, there are more than three push rod connecting ends 246, the three push rod connecting ends 246 are arranged in a triangular array and are spaced between two connecting ring seats 244 of some parts, there are more than three guide connecting column holes, guide columns 245 are arranged in the guide connecting column holes, the three guide columns 245 are arranged in a triangular array in the hole and are spaced between two connecting ring seats of another part, that is, each push rod connecting end and each guide connecting column hole are respectively arranged between each connecting ring seat with a staggered interval.

[0040] reference Figure 1-7As shown, in a preferred embodiment, the middle adjustable component also includes a sliding column 28, a column connecting plate seat 29 and a track seat 280. Both ends of the sliding column 28 are provided with double-hole connecting seats for connection, one end of which is used for rotationally connecting to the connecting ring seat, and the other end is used for rotationally connecting to the column connecting plate seat 29. The column connecting plate seat 29 is also provided with a connecting earring 291 for connection. The bottom surface of the column connecting plate seat 29 is formed with a track space wall corresponding to the track seat, that is, the column connecting plate seat 29 is slidably connected to the track seat 280. The column connecting plate seat 29 is used to form a welding positioning of the slats of the middle body of the cylindrical structure of the flower basket with multiple slats on the movable connecting disk. The column connecting plate seat 29 protrudes from the middle When the edge of the middle disc body 241 is abutted, the middle slat structure is pressed and positioned to ensure that the middle position of the slat is accurately and firmly positioned. There are more than six groups of column connecting plate seats 29 and track seats 280, which are distributed in a hexagonal array. One end of a push rod 32 is connected to the push rod connecting end 246, and the other end of the push rod 32 is connected to the output shaft of the power motor. The push rod 32 can be a telescopic rod. The power motor is arranged on the bottom surface of the middle disc body 241. A guide column 245 is connected to the guide connecting column hole. One end of the guide column 245 is connected to the guide connecting column hole, and the other end is connected to the circular plate connecting seat of the middle disc body. The guide column 245 is used for guiding. The movable connecting disc 24 2 is slidably connected to the positioning connecting rod 26. Through the main driving force of the push rod 32, the sliding column 28 on the movable connecting disk 242 is simultaneously driven to rotate and stretch, and at the same time, the movable connecting disk is pulled on the positioning connecting rod 26 to perform a stretching movement toward the tail adjustable disc member. When the push rod 32 pushes the movable connecting disk to move toward the tail adjustable disc member, the sliding column 28 is simultaneously pulled, driving the column connecting plate seat 29 to slide on the track seat. At this time, the column connecting plate seat 29 slides toward the inner part of the middle disc body 241, which is equivalent to releasing the positioning of the middle slat body of the cylindrical structure of the flower basket with multiple slats. Then, when the push rod 32 performs the operation of retracting the rod body, the movable connecting disk is executed. As the positioning disc seat moves, the sliding column 28 is simultaneously executed to drive the column connecting plate seat 29 to slide on the track seat. At this time, the column connecting plate seat slides outward, and then part of the column connecting plate seat 29 protrudes from the edge of the middle disc body, and the middle plate structure is pressed and positioned in abutment manner, so that the positioning structure in the middle is firm, ensuring that each welding surface before welding can be pressed and positioned, which is convenient for the middle part of the cylindrical structure of the flower basket with multiple plates to be automatically formed first, and then to be welded independently, and also to ensure that there is no gap surface or hole surface on the welding surface of each plate and the annular plate. If there is a gap or empty surface, it will cause rust on the gap surface or hole surface to be welded later;It also improves welding efficiency and reduces manual operation. The structure of the tail adjustable disc 25 is the same as that of the middle adjustable disc 24. The tail adjustable disc 25 is slidably connected to the tail rod body of the connecting rod. The tail adjustable disc 25 is used to perform welding positioning of the cylindrical structure at the tail end of the connecting rod.
