A rotating wheel 3 is connected to the surface of the balance bar 2. A limiting plate 4 is sleeved on the outer surface of the balance bar 2. A screw groove 21 is opened on the surface of the balance bar 2. A support plate 31 is movably connected to the inner side of the rotating wheel 3. A screw 32 is fixedly connected to the surface of the support plate 31. A screw sleeve 41 is fixedly connected to the outer surface of the limiting plate 4. A screw shank 42 is sleeved on the outer surface of the screw sleeve 41. A retaining ring 43 is fixedly connected to the surface of the screw shank 42. A retaining plate 44 is fixedly connected to the end of the screw sleeve 41 away from the limiting plate 4. A pressure block 45 is fixedly connected to the inner side of the retaining plate 44. Through the connection of the support frame 1 and the connecting sleeve 11, and the connection of the connecting sleeve 11 and the balance bar 2, the balance bar 2 is supported on the support frame 1. Through the action of the balance bar 2, the use and placement operation of the rolled insulating film is completed.

[0024] Furthermore, the support frame 1 is in the shape of a cross, and the support frame 1 is connected to both ends of the balance bar 2 in two sets. The shape of the support frame 1 facilitates the placement and use of the support frame 1, improves its stability during placement and use, and reduces its weight, making it easier to transport and operate.

[0025] Furthermore, the support frame 1 is connected to the balance bar 2 via the connecting sleeve 11, the support plate 31 is connected to the balance bar 2 via the screw 32 and the screw groove 21, and the rotating wheel 3 is rotatably connected to the balance bar 2 via the support plate 31 and the screw 32. Through the connection of the support frame 1 and the connecting sleeve 11, the connection and support effect between the balance bar 2 and the support frame 1 is achieved by the connection of the connecting sleeve 11 and the balance bar 2.

[0026] Furthermore, the limiting disc 4 is in the shape of a disc, and the limiting disc 4 is distributed in two opposing groups on the outer surface of the balance bar 2. Through the connection between the limiting disc 4 and the balance bar 2, the limiting disc 4 achieves the limiting and supporting effect on the roll of thermal insulation film on the balance bar 2.

[0027] Furthermore, the screw shank 42 is connected to the screw sleeve 41 by a thread, and the abutment ring 43 is in the shape of a cylindrical ring.
