[0002] With the development of digital shooting equipment such as camera, it is more and more miniaturized, and the quality requirement of shooting is also higher and higher. During shooting, the shooting equipment often needs to move horizontally. However, the traditional moving method is to move the shooting equipment manually, which has poor uniformity and stability, and the shooting effect is not good. Therefore, people invent a shooting slide rail to move the shooting equipment on the slide rail for shooting. The existing shooting track improves the stability and uniformity, and improves the shooting effect.

[0003] The utility model discloses a photography slide rail including a slide rail, a slide block seat slidably arranged on the slide rail, and a driving device arranged on the slide rail and used for driving the slide block seat to slide on the slide rail. The photography slide rail further includes a brake device arranged on the slide rail and used for preventing the slide block seat from sliding downward along the slide rail. The brake device prevents the camera or the video camera on the slide block seat from sliding or falling due to sudden power failure of the driving device, thereby protecting the camera or the video camera and the photography slide rail. However, when the slide rail has a long stroke, the motor is arranged at one end of the slide rail, which causes the slide rail to deform severely at one end. Therefore, the strength of the slide rail needs to be improved, which increases the weight of the slide rail and makes it inconvenient to carry. SUMMARY
