In the connecting box 54, the rotating columns 56 on both sides are symmetrical with the middle rotating column 56 as the axis, and the rotating column 56 is fixed to the output shaft of the motor 2 55 by bolts. The four limiting wheels 57 are fixedly connected to the three rotating columns 56 respectively. Two limiting wheels 57 are fixedly connected to the middle rotating column 56. The cross-section of the limiting wheel 57 is "I" shaped. Four steel ropes 8 are fixedly connected to the four limiting wheels 57 respectively. Two chains 58 are respectively arranged between the three rotating columns 56. Four through holes 59 are opened on the connecting box 54. The four through holes 59 are respectively located directly below the four limiting wheels 57. The base 1 is provided with a fixing component 6 and an auxiliary component 7.

[0025] Further, such as Figure 1 and Figure 2 As shown, the lifting assembly 5 also includes a motor 51 and a screw 52. The motor 51 is fixed to the cross bar 3 by bolts, and the screw 52 is fixed to the output shaft of the motor 51 by bolts. Two sliders 53 are threadedly connected to the screw 52.
