[0043] After adopting the technical solution disclosed in the utility model, it can achieve:

[0044] When using the device, the door frames 2 are set up at a certain interval in the fruit tree field planted in rows, so that the film used for covering and shielding is set up by the device to cover the outside of the fruit trees for insulation, that is, a plastic greenhouse structure is set up. The film adopts a single-layer plastic film 17 and reinforcing rods 18 fixed at a certain equidistant on the plastic film 17. The length of the reinforcing rods 18 is slightly larger than the distance between two adjacent groups of door frames 2. Therefore, after the plastic film 17 is unfolded, the two ends of the reinforcing rods 18 on the plastic film 17 are clamped by two door frames 2 in one group of the device for limiting the position; the two groups of the device are used in conjunction to realize the unfolding of one side of the film, and the side edges of the plastic film 17 are fixedly arranged on the mounting seats 3 located on the inner side or on the outer side at both ends by the reinforcing rods 18.
