Slot 64. Among them, the end of the surrounding wall of each C-shaped chute of the slide rail 6 is a smooth arc. When contacting with the inverted L-shaped guide plate, the amplitude of friction is reduced to form a line contact fit, thereby reducing the slide rail 6 and The friction between the inverted L-shaped guide plates makes the sliding of the adjusting bracket 3 smoother. Correspondingly, the end of the inverted L-shaped guide plate is also a smooth arc surface. When the inverted L-shaped guide plate cooperates with the groove wall of the C-shaped chute 64, a certain gap is left to prevent the inverted L-shaped guide plate from following the chute. The friction between the chute 64 and the inverted L-shaped guide plate is too large when 64 is relatively slid.

In order to prevent dust or foreign matter from falling into the C-shaped chute 64, as shown in FIG. 5, the upper port of the C-shaped chute 64 is provided with a sealing plug 65 so as to block the dust or foreign matter. As shown in FIG. 19, the sealing plug 65 includes a dustproof sheet 651 and a limiting step 652, wherein the dustproof sheet 651 is used to cover both ends of the C-shaped chute 64, and the limiting step and the The hook pressing portion 41 cooperates to limit the position of the hook 4. When the sealing plug 65 is installed at the lower end of the slide rail 6, the limiting step 652 prevents the hook 4 from moving further downward (as shown in FIG. 8), thereby avoiding when the hook 4 is located at the lower limit position of the sliding groove 64 Due to a user's operation error, pressing the hooking portion 41 of the hook 4 again to further move the hook 4 downward, resulting in the situation that the hook 4 and the adjusting bracket 3 slide out of the slide slot 64 together with the sealing plug 65.

As shown in FIG. 11, the slide rail 6 includes a left slide rail 6a (as shown in FIG. 10b), a right slide rail 6b (as shown in FIG. 10d), and a middle slide rail 6c (as shown in FIG. 10c). The middle slide rail 6c is disposed between the left slide rail 6a and the right slide rail 6b, and the length of the middle slide rail 6c is shorter than the length of the left slide rail 6a and the right slide rail 6b.
