Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a slide rail. [Prior Art] [0002] A slide rail is a widely used device, and is generally used to connect two items that can move relative to each other, such as a drawer, a cabinet server, and the like. [0003] A common slipper has a three-section slide rail. Generally, a three-section slide rail generally includes a first rail, a second rail, and a third rail, and between the first rail, the second rail, and the third rail. The slidable connection structure is generally divided into two types: one is a ball slide structure and the other is a friction type slide structure. The ball slide is easy to push and pull, but the cost is high, and the space occupied during installation is large, while the friction type slide rail has low cost and strong carrying capacity, but the sliding property is poor. SUMMARY OF THE INVENTION [0004] In view of the above, it is necessary to provide a slide rail having better slidability and increased reliability. [0005] A slide rail includes a fixing bracket, a first handle, a second handle and a third rail. The fixing bracket includes a fixing plate, and two sides formed by symmetrical bending of the two sides of the fixing plate in the same direction a side arm, the end of each side arm is folded back to form an end wall parallel to the fixing plate, the first rail is received between the two arms of the fixing bracket, and the ball is disposed between the second rail and the first rail The ball frame, the third rail slidingly contacts the second rail. [0006] Compared with the prior art, a ball frame with balls that can slide the first rail relative to the second rail is provided between the first rail and the second rail of the slide rail, which is beneficial to 100100141 Form No. A0101 No. 4 Page / Total 15 pages 1002000236-0 201230933 [0007]
