[0053] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0054] The working principle of the present invention is as follows: first, the three-dimensional roll structure body 3 and the fixed seat 4 are placed on the inner bottom wall of the energy-saving box 2, and the hydraulic telescopic rod 63 is started to drive the transmission bar 69 at the output end to move forward linearly. When the transmission bar 69 moves, it squeezes and drives the two sliding sleeves 67 to slide on the transmission bar 69 toward the opposite side. When the two sliding sleeves 67 slide, they drive the two transmission arms 66 to rotate on the two limit shafts 62. When the two transmission arms 66 rotate, they drive the two connecting blocks 64 through the two connecting arms 68, so that the two connecting blocks 64 are limited to the same straight line through the linear telescopic limit sleeve 61, and move toward the opposite side, so that the two fixed plug rods 65 are tightly inserted in the two fixed The fixing hole 5 is used to stably fix the fixing seat 4 and the three-dimensional rolling structure body 3, and then the motor 85 is started to drive the first gear 87 at the output end to rotate. When the first gear 87 rotates, it drives the second gear 88 to rotate on the fixed plate 83 through the rotating shaft 86. The rotation of the rotating shaft 86 drives the rotating arm 89 to rotate synchronously. When the rotating arm 89 rotates, it moves in the inner wall of the connecting groove 84 through the rotating shaft 810, and at the same time squeezes and drives the connecting groove 84 and the connecting column 82, so that the connecting column 82 drives the energy-saving box 2 to move upward in a straight line through the linear limit of the two telescopic guide rods 81, so as to adjust the energy-saving box 2 and all structures thereon, including the three-dimensional rolling structure body 3 therein, to a suitable working height.
