The position of the support rod is adjusted by moving the first sliding rod and the second sliding rod, thereby facilitating auxiliary support and pre-folding operations for the plastic film.

[0030] The body 1 includes a fixing rod 4, which is provided with a mounting rod 1 5 and a mounting rod 2 6. The end of the mounting rod 1 5 away from the fixing rod 4 is connected to the end of the mounting rod 2 6 away from the fixing rod 4. The mounting rod 1 5, the mounting rod 2 6 and the fixing rod 4 form a triangle.

[0031] In actual use, the plastic film hits the end of the cross bar 3 away from the body 1, and the plastic film moves under the guidance of the mounting rod 1 5 and the mounting rod 2 6, and hits the connecting end of the mounting rod 1 5 and the mounting rod 2 6, thereby folding along its own center line.

[0032] The body 1 is provided with a guide rod 7, which is connected to the end of the mounting rod 5 away from the cross bar 3. The guide rod 7 is provided with a guide groove 8, which is located on the upper end surface of the guide rod 7, and the extension direction of the guide groove 8 is the direction of the guide rod 7.

[0033] Mounting rod 1 5 is provided with a support rod 9, which connects mounting rod 1 5 and mounting rod 2 6. The length direction of support rod 9 is parallel to the length direction of cross bar 3. In actual use, support rod 9 includes connecting rod 10, sliding rod 1 11, and sliding rod 2 12. Connecting rod 10 is provided with a sliding hole 13, which passes through connecting rod 10. Both sliding rod 1 11 and sliding rod 2 12 slide on the wall of sliding hole 13.
