[0035] In this embodiment, the arc portion 333 is provided with a plurality of first toggle members 334, and the connecting frame 43 is rotated to different angles. Different first toggle members 334 are clamped in the clamping portion 331, so that the second driving member 42 drives the base assembly 2 to rotate around the first rotating shaft 31, thereby expanding the rotation angle of the curved product and making it easier to apply film to various parts of the curved product.

The second transmission pair also includes a transmission platform 44 arranged on the second driving member 42 and a top fork 45 slidably connected to the transmission platform 44, and the connecting frame 43 is provided with a second toggle member 46 cooperating with the top fork 45; the direction perpendicular to both the first direction and the second direction is defined as the third direction, the second driving member 42 drives the transmission platform 44 to move along the third direction, drives the top fork 45 to move along the third direction, the top fork 45 abuts against the second toggle member 46, drives the second rotating shaft 41 to rotate, thereby driving the connecting frame 43 to rotate around the second rotating shaft 41, and drives the base assembly 2 for fixing the curved surface product to rotate around the second rotating shaft 41.

[0037] Specifically, the connecting frame 43 is rectangular, including two oppositely arranged first side plates 431 and two oppositely arranged second side plates 432, two first rotating shafts 31 and two second rotating shafts 41 are each provided with, one first side plate 431 is rotatably connected to one first rotating shaft 31, and the two first rotating shafts 31 are arranged oppositely, and one second side plate 432 is fixedly connected to one second rotating shaft 41, and the two second rotating shafts 41 are arranged oppositely; there are two fixing frames 22, which are respectively located at the two ends of the fixing plate 21, and one fixing frame 22 is fixedly connected to one first rotating shaft 31; there are two supporting parts 332, racks 34 and gears 35, one rack 34 is fixed to one supporting part 332, one gear 35 is sleeved and fixed to one first rotating shaft 31 and meshed with one rack 34, one supporting part 332 is provided between the fixing frame 22 connected to the same first rotating shaft 31 and the first side plate 431, and the two ends of the arc portion 333 are respectively connected to one side of the two supporting parts 332 facing the same second side plate 432.

[0038] In this embodiment, the first driving member 32 and the second driving member 42 are cylinders, but they may also be other driving devices.

[0039] Please refer again Figure 5 The second toggle member 46 is disposed on the second side plate 432 on the side of the support portion 332 away from the arc portion 333. Two second toggle members 46 are provided, and are respectively located on both sides of the second rotating shaft 41; two top forks 45 are provided, and are respectively located at both ends of the transmission platform 44, and one top fork 45 corresponds to one second toggle member 46. Through this arrangement, the connection frame 43 can rotate clockwise or counterclockwise relative to the bracket 1, thereby expanding the rotation angle of the curved surface product and making it easier to apply film to various parts of the curved surface product. Specifically, the two top forks 45 are respectively a first top fork 451 and a second top fork 452. When the first top fork 451 needs to be driven to abut against the corresponding second toggle member 46, the first top fork 451 is first driven to slide relative to the transmission platform 44 so that the transmission platform 44 is located at the lower end of the first top fork 451, and the second top fork 452 is driven to slide relative to the transmission platform 44 so that the transmission platform 44 is located at the upper end of the second top fork 452. Similarly, when the second top fork 452 needs to be driven to abut against the corresponding second toggle member 46, the second top fork 452 is first driven to slide relative to the transmission platform 44 so that the transmission platform 44 is located at the lower end of the second top fork 452, and the first top fork 451 is driven to slide relative to the transmission platform 44 so that the transmission platform 44 is located at the upper end of the first top fork 451. This arrangement prevents the non-working top fork 45 from abutting against the corresponding second toggle member 46 and affecting the rotation of the connecting frame 43.
