The goods are hoisted at the hook 52 on the extension tube 5 of the inclined bracket 2, and the forklift lifts and hoists the goods. The inclined bracket 2 is provided with an adjusting member 6. When the hoisting height of the goods is high, the position of the extension tube 5 is extended by the adjusting member 6, and the position of the extension tube 5 is changed to adjust the maximum hoisting height of the forklift, so as to facilitate the hoisting of goods at high places.

[0038] Reference Figure 4The adjusting member 6 includes a first screw 61 and a slider 62. The oblique bracket 2 is located at the sliding groove 21 and a mounting box 23 is provided on the downward side. The first screw 61 is rotatably installed at the mounting box 23 and the first screw 61 and the extension tube 5 are arranged parallel to each other. A slider 62 is provided at the downward end of the extension tube 5. The oblique bracket 2 is located at the sliding groove 21 and a through hole 24 is opened on the downward side. One side of the slider 62 passes through the through hole 24 and is slidably installed at the mounting box 23 and is threadedly connected with the first screw 61.

[0039] Reference Figure 4 The oblique bracket 2 is provided with a driving member 7 at one side of the installation box 23. The driving member 7 includes a worm wheel 71 and a worm 72.
