[0023] In this embodiment, a guide rod 10 is slidably inserted at the upper end of the lifting plate 9 to keep the lifting plate 9 lifted straight and prevent it from tilting. The lower end of the guide rod 10 passes through the lifting plate 9 and is fixedly connected to the upper end of the base 1. The number of guide rods 10 is four in a rectangular distribution, which is used to improve the stability of the lifting plate 9 during lifting and further prevent it from tilting. A servo motor 6 is fixedly embedded at the upper end of the base 1 to drive the first lead screw 7 to rotate. The end of the output shaft of the servo motor 6 is fixedly connected to the first lead screw 7 to drive the lifting plate 9 to lift and lower. The upper end of the first lead screw 7 passes through the lifting plate 9, and the first lead screw 7 and the lifting plate 9 are threadedly connected.

[0024] In this embodiment, two first support plates 2 are fixedly connected to the bottom of the storage groove for supporting the tensioning wheel 3. The two first support plates 2 are respectively located on both sides of the second support plate 8. The upper end of the first support plate 2 and the lower end of the second support plate 8 are provided with a connecting groove. A tensioning wheel 3 is provided in the connecting groove for adjusting the tension of the cable steel belt. Both ends of the tensioning wheel 3 are fixedly connected with a support rod 4 for supporting the tensioning wheel 3.
