[0002] With the intensification of the energy crisis and the increasingly serious environmental problems, photovoltaic modules, as an important form of renewable energy, have received more and more attention and research. After the photovoltaic modules are grouped and supported, they usually need to be wrapped with a film for subsequent transportation. At present, according to different film winding requirements, this process is usually divided into two methods: machine film winding and manual film winding.

[0003] However, the current manual film winding is usually completed with a simple film winding pull rod. The film winding pull rod is a tool for manual film winding, usually a long-handled handheld device with a shaft cylinder or reel loaded with the film. When a worker uses the film winding pull rod, the film is pulled out from the shaft cylinder and then manually wound around the photovoltaic module to achieve the effects of protection and fixation. This process requires the worker to frequently squat up and down and operate back and forth many times, which is not only time-consuming and laborious, but also the film winding effect is often poor, and the appearance quality of the photovoltaic module after film winding cannot be guaranteed.
