[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 1-5 As shown, in the utility model, a slide rail 2 is provided on the upper surface of the guide rail body 1, and the slide rail 2 is adapted to a camera base that slides therewith. The camera can slide along the slide rail 2 on the guide rail body 1. During long-distance shooting, different guide rail bodies 1 can be spliced ​​together, and the camera is transferred from one guide rail body 1 to another guide rail body 1 to complete the long-distance shooting task.

[0021] In the utility model, connecting components 3 are respectively provided at both ends of the guide rail body 1, and the connecting components 3 include a mounting plate 3-1 and a mounting sleeve 3-2. The mounting sleeve 3-2 is fixed to the outer side of the end of the mounting plate 3-1, and the mounting plate 3-1 is fixed to the lower surface of the two ends of the guide rail body 1. The mounting sleeves 3-2 on the two groups of connecting components 3 are staggered. During the splicing process of two different guide rail bodies 1, the connecting components 3 on different guide rail bodies 1 are close to each other, and one group of mounting sleeves 3-2 is respectively inserted into another group of mounting sleeves 3-2 and staggered. The distance between adjacent mounting sleeves 3-2 is equal to the width of the mounting sleeves 3-2, so that the two groups of mounting sleeves 3-2 are coaxial and matched, and the mounting shaft 4 is inserted so that the mounting shaft 4 and the mounting sleeve 3-2 are threadedly matched so that the two guide rail bodies 1 are installed.

[0022] A lifting leg 5 is provided at the bottom of the guide rail body 1 . The lifting leg 5 may be an electrically controlled hydraulic lifting leg or a manual mechanical lifting leg. The purpose is to adjust the height of the guide rail body 1 .

[0023] One set of connecting components 3 has an internal thread on the inner wall near the outer mounting sleeve 3-2, and the mounting shaft 4 has an external thread 4-1 near the end that matches the thread of the mounting sleeve 3-2. The end of the mounting shaft 4 with the external thread 4-1 can be quickly inserted into the mounting sleeve 3-2. When the external thread 4-1 on the mounting shaft 4 contacts the internal thread on the mounting sleeve 3-2, the mounting shaft 4 is screwed to achieve the installation of the two sets of connecting components 3.

[0024] A guide shaft 6 and a guide groove 7 are respectively provided at both ends of the guide rail body 1, and the guide shaft 6 and the guide groove 7 are adapted to each other. When the two guide rail bodies 1 approach each other, the guide shaft 6 on one guide rail body 1 enters the guide groove 7 on the other guide rail body 1 to guide the guide rail body 1 during the movement. After the guide shaft 6 and the guide groove 7 are installed in place, two sets of different installation sleeves 3-2 are also installed in place, that is, coaxially arranged to facilitate the insertion of the installation shaft 4, and to facilitate the installation and positioning of the two sets of guide rail bodies 1.
