The telescopic guide rail comprises a first guide rail body and a second guide rail body, and a first containing cavity is formed in the second guide rail body; the first guide rail is arranged in the first containing cavity in a penetrating mode, and the first guide rail can stretch out of or retract into the first containing cavity. A first guide groove and a second guide groove are respectively formed in the first guide rail and the second guide rail along the length direction, and the first guide groove and the second guide groove are arranged in parallel; when the first guide rail extends out of the first accommodating cavity, the first guide groove is connected with the second guide groove; the telescopic guide rail further comprises a jacking device, the jacking device is installed at the front end of the second guide rail, and the jacking device is configured to push the first guide rail to ascend when the first guide rail extends out of the first containing cavity, so that the first guide groove and the second guide groove are aligned to pass through a nested structure composed of the first guide rail and the second guide rail. And the folding chair meets the use requirements, is convenient to adjust and use, can be retracted when not in use, reduces the occupied space and is high in portability.
