[0024] It is understandable that the design of the reset spring 5 needs to take into account factors such as restoring force, service life, and reliability to ensure that the mechanical device can accurately and stably complete the reset action.

[0025] In this embodiment, a circular hole is opened in the turntable 3, and the turntable 3 is mounted on the connecting shaft 2 through the circular hole. A limiting hole 7 is opened in the limit plate 4, and a movable hole 9 is opened in the movable rod 6. A fixing bolt 8 passes through the connection between the limiting hole 7 and the movable hole 9.

[0026] There are several limiting holes 7 formed on the limiting plate 4 .

[0027] It should be noted that the limiting hole 7 and the movable hole 9 are matched.

[0028] In this embodiment, a limiting groove is provided inside the turntable 3 , and the connecting frame 10 limits the turntable 3 on the connecting shaft 2 through the limiting groove.

[0029] In this embodiment, the fixed structure also includes a limit frame 17, a sealing cylinder 18, a small piston 19 and a connecting tube 20. The limit frame 17 is movably connected to the turntable 3, the sealing cylinder 18 is fixedly connected to the connecting shaft 2, the small piston 19 is in contact with the inner wall of the sealing cylinder 18, the sealing cylinder 18 is connected to one side of the connecting tube 20, and the other side of the connecting tube 20 is connected to the connecting shaft 2. The limit frame 17 is movably connected to the inside of the sealing cylinder 18 through the small piston 19.

[0030] A sealing cavity is defined in the sealing cylinder 18 .

[0031] It should be noted that a slot is provided in the turntable 3 , and the limiting frame 17 is limited by the slot and the turntable 3 .

[0032] In this embodiment, a handle 11 is in contact with one side of the connecting shaft 2 , and a limiting rod 13 is fixedly connected to one side of the handle 11 . The limiting rod 13 passes through the connecting shaft 2 .

[0033] In this embodiment, a connecting spring 12 is disposed on the outer sleeve of the limiting rod 13 , and an end of the connecting spring 12 is fixedly connected to the inner wall of the connecting shaft 2 .

[0034] In this embodiment, a limiting seat 14 is fixedly connected inside the connecting shaft 2, a limiting hole is provided in the limiting seat 14, an extension rod 15 passes through the limiting hole, one end of the extension rod 15 is fixedly connected to the limiting rod 13, and the other end of the extension rod 15 is fixedly connected to a large piston 16, which fits the inner wall of the connecting shaft 2.

[0035] The large piston 16 is attached to the connecting shaft 2 and forms a sealed cavity with the limiting seat 14 .

[0036] The working principle of the above embodiment is:

[0037] First, the turntable 3 is installed on the wrapping machine body 1 through the connecting shaft 2. The reset spring 5 can pull the movable rod 6 to adjust the length in the limit plate 4. The movable rod 6 is moved to drive the connecting frame 10 to limit the turntables 3 of different specifications. When the turntable 3 is limited by the connecting frame 10, the movable hole 9 opened in the movable rod 6 is connected with the limiting hole 7 of appropriate height in the limiting plate 4, and the height of the movable rod 6 is limited by the fixing bolt 8, so as to limit the turntables 3 of different specifications on the connecting shaft 2.

[0038] Secondly, the limiting frame 17 is connected to the turntable 3 to limit the position, thereby enhancing the stability of the turntable 3 when rotating on the connecting shaft 2.

[0039] Finally, by pulling the handle 11, the limit rod 13 is driven to cooperate with the connecting spring 12, and the extension rod 15 is driven to move through the limit rod 13, and the large piston 16 is driven to move through the extension rod 15. When the large piston 16 moves, the sealing gas in the limit seat 14 and the connecting shaft 2 can be transmitted to the connecting pipe 20, and the gas is transported to the sealing cylinder 18 through the connecting rod 20. When the gas enters the sealing cylinder 18, the small piston 19 can drive the limit frame 17 to move, so that the limit frame 17 is out of contact with the turntable 3, and the turntable 3 can be flexibly removed from the connecting shaft 2, so as to enhance the stability of the turntable fixing mechanism of the vertical wrapping machine.
