One end of the two first fixing shafts 6.31 and one end of the two second fixing shafts 6.33 are connected through the fixing screw 6.34. The two first fixing shafts 6.31 and the two second fixing shafts 6.33 are symmetrically distributed. Two first springs 6.35 are installed on the outer sleeve of the fixing screw 6.34. Nuts for limiting the first spring 6.35 are installed at both ends of the fixing screw 6.34. The first spring 6.35 plays an elastic supporting role for the first fixing shaft 6.31 and the second fixing shaft 6.33. The two ends of the screen are clamped and fixed by the elastic force of the first spring 6.31 to prevent the screen from falling off during the installation process, thereby facilitating the installation operation.

[0022] An insert block 6.32 is provided at one end of the first fixed shaft 6.31, and a square groove for installing the insert block 6.32 is opened at one end of the shaft head 6.1. The insert blocks 6.32 at one end of the two first fixed shafts 6.31 are both inserted and installed in the square groove, which plays a fixing role on the shaft body 6.3. At the same time, the shaft body 6.3 can be driven to rotate through the shaft head 6.1, thereby controlling the tension of the screen.

[0023] The first fixed shaft 6.31 and the second fixed shaft 6.33 are both rod-shaped structures with semicircular cross-sections. One end of the first fixed shaft 6.31 and one end of the second fixed shaft 6.33 are provided with cylindrical grooves for installing the connecting rod 6.36. The outer wall of the cylindrical groove is penetrated with a long hole for accommodating the limit slider 6.37. The other end of the first fixed shaft 6.31 and the other end of the second fixed shaft 6.33 are connected through the connecting rod 6.36 and the limit slider 6.37. The limit slider 6.37 is fixedly installed on the outer walls of the two ends of the connecting rod 6.36. The limit slider 6.37 plays a limiting and guiding role for the first fixed shaft 6.31 and the second fixed shaft 6.33 by sliding in the long hole on the connecting rod 6.36.

[0024] Furthermore, a second spring 6.38 is installed on the outer sleeve of the connecting rod 6.36, one end of the second spring 6.38 abuts against the first fixed shaft 6.31, and the other end of the second spring 6.38 abuts against the second fixed shaft 6.33. The second spring 6.38 plays an elastic supporting role for the first fixed shaft 6.31 and the second fixed shaft 6.33.
