[0022] As a technical optimization solution of the utility model, both sides of the two sliders 9 are fixedly connected with connecting blocks 10, and the ends of the connecting blocks 10 are in a "U" shape; the two ends of the connecting blocks 10 are in a "U" shape, and their ends are in conflict with the ends of the guide rail 2, which can effectively prevent the slider 9 from moving upward and then slipping off the guide rail 2 during operation, thereby increasing the sliding stability of the slider 9.

[0023] As a technical optimization scheme of the utility model, the end of the connecting block 10 is slidably connected to the end of the guide rail 2, and the guide rail 2 and the connecting block 10 are limited by a limiting structure 6, and the limiting structure 6 includes a limiting hole 603, and a plurality of limiting holes 603 are equidistantly opened at the top of the guide rail 2, and a clamping block 605 is engaged in one of the limiting holes 603, and the clamping block 605 is slidably connected to the connecting block 10 connected to the inner side of the slider 9; the end of the clamping block 605 is fixedly connected to a pull rod 601, and the pull rod 601 is in a "U"-shaped structure, and the two ends of the pull rod 601 are respectively fixed to the top of the two clamping blocks 605, and the two ends of the pull rod 601 are fixedly connected to a tension spring 604, and the other end of the tension spring 604 is fixed to the top of the connecting block 10; the pull rod 601 is lifted up, so that the card block 605 slides upward and no longer engages with the limiting hole 603 on the guide rail 2. At the same time, the tension spring 604 is extended, and then the back plate 3 is pulled, so that the back plate 3 drives the slider 9 and the connecting block 10 to slide outward on the guide rail 2. When the back plate 3 moves to the appropriate position, the pull rod 601 is released, the tension spring 604 is reset, and the card block 605 is driven downward to engage with one of the limiting holes 603, thereby limiting the slider 9 and preventing the slider 9 from driving the back plate 3 to slip off the slide rail, and fixing the slider 9 to prevent the slider 9 from driving the back plate 3 to slide back and forth, thereby increasing the stability of the back plate 3, and the pull rod 601 is set to a "U" shape structure, with both ends connected to the top surfaces of the two card blocks 605, so that the operator can operate the limiting structure 6 with one hand, making the operation more flexible and convenient.

When the back plate 3 moves to a suitable position, the pull rod 601 is released, and the tension spring 604 is reset, driving the block 605 downward to engage with one of the limiting holes 603, so that the position of the back plate 3 is fixed.
