The inner side of the limiting slider 54 is fixedly connected to the outer side of the hook 4. An anti-falling mechanism 6 is slidably connected to the top of the horizontal limiting rod 52.

[0037] refer to Figure 5 The anti-fall-off mechanism 6 includes a sliding frame 61, which is slidably connected to the top of the transverse limiting rod 52. An adjusting plate 62 is slidably connected to the inner cavity of the sliding frame 61. The bottom of the adjusting plate 62 extends through to the outside of the sliding frame 61. A positioning hole 63 is provided on the surface of the adjusting plate 62. A bearing plate 64 is fixedly connected to the bottom of the adjusting plate 62.

[0039] refer to Figure 2 A reinforcing block 7 is fixedly connected to the outer side of the vertical slide rail 51, and the bottom of the reinforcing block 7 is fixedly connected to the frame 1.

[0040] As a technical optimization of this utility model, the reinforcement block 7 can reinforce the vertical slide rail 51, strengthen the connection between the vertical slide rail 51 and the frame 1, and enable the two to be connected more stably.

[0041] refer to Figure 3 A limiting slide bar 8 is provided through the top of the transverse limiting rod 52, and the outer side of the limiting slide bar 8 is fixedly connected to the inner side of the frame 1.
