Second positioning blocks 202 are provided at both ends of the second guide rail component 200. The length of the intermediate adapter 300 is less than the length of the first guide rail component 100 or the second guide rail component 200. For example, the length of the second roller carrier is about one-half of the length of the second guide rail component 200, and the length of the intermediate adapter 300 is about one-third of the length of the first guide rail component 100 or the second guide rail component 200, so as to increase the telescopic stroke of the guide rail. At the same time, the second positioning blocks 202 at both ends of the second guide rail component 200 are used to prevent the second roller carrier from slipping off the second guide rail component 200.
