The sliding block 204 can be sleeved with the slide rail 2 to assist the fixed block 201 to slide along the path of the slide rail 2. The first pull rod 5 and the second pull rod 501 have the same height. At the same time, the top ends of the first pull rod 5 and the second pull rod 501 can be sleeved with both ends of the spring 502. When the fixed block 201 slides on the top of the slide rail 2, the elastic force of the spring 502 can be used to fix and adjust the distance.
