The B regulating wheel 17 on the A pulley can drive the other end of the A synchronous belt 3 to adjust the length so as to match the length of the track, the fixing screw 6 is locked after the track length is adjusted, proper pulling force is applied to the part of the A synchronous belt 3 extending to the outside of the track to ensure the tightness of the A synchronous belt 3 in the track, then the B regulating wheel 17 is locked, finally, the redundant part B reserved outside the track at the A synchronous belt 3 is cut off by scissors, the spring 14 can tightly push one end head of the A synchronous belt 3 on the pulley, and the head is prevented from interfering with the inner side of the track. The curtain cloth is fixed on the hanging wheel 22 and the pulley arm 23.
In light of the above, the present invention is not limited to the above embodiments, and various changes and modifications can be made by the worker without departing from the scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
