The lifting or lowering direction can be adjusted by sliding the telescopic rod 8 in the circular slide groove 10, a fixed block 2 is fixedly connected to the bottom surface of the base 1, and a supporting leg 3 is hinged on the fixed block 2, and a pulley 4 is fixedly connected to the side wall of the supporting leg 3, and the supporting leg 3 can be folded and the pulley 4 can be lowered to move the crane, and the supporting leg 3 can be rotated to open the supporting leg 3 after moving to the target position, and the inner wall of the fixed block 2 is used to keep the supporting leg 3 vertical to play a stable supporting role, and a lifting mechanism 9 with adjustable lifting distance is provided on the top of the connecting column 7.

[0024] The lifting mechanism 9 includes: a support plate 901, an adjustment plate 902, a hook 903, a limit hole 904, a limit rod 905, a limit spring 906, a slider 907, a counterweight 908, a positioning rod 909, an elastic spring 910, and a positioning hole 911. The support plate 901 is fixedly connected to the top of the connecting column 7, the side wall of the support plate 901 is penetrated and slidably connected with the adjustment plate 902, the bottom surface of the adjustment plate 902 is fixedly connected with the hook 903, and the target is hooked and moved by the hook 903, the limit hole 904 is provided on the surface of the adjustment plate 902, the surface of the support plate 901 is penetrated and slidably connected with the limit rod 905, the bottom surface of the limit rod 905 and the surface of the support plate 901 are fixedly connected with the limit spring 906, the limit rod 905 and the limit hole 904 are matched in size and shape, the adjustment plate 902 can be slid to adjust the lifting and lowering distance, and the limit rod 905 is driven by the limit spring 906 to insert into the limit hole 90 4, the slider 907 is slidably connected to the surface of the support plate 901, and a counterweight 908 is fixedly connected to the side wall of the slider 907. There are two counterweights 908, and they are symmetrically distributed compared to the slider 907. The counterweight 908 is used to keep the crane balanced as a whole.
