[0031] Furthermore, a convex groove 13 is opened at the bottom center position of the second movable disc 11, and an annular sealing gasket 14 is fixedly installed on the bottom inner wall of the convex groove 13. A circular groove 16 is opened at the top center position of the second movable disc 11, and the circular groove 16 is communicated with the inside of the convex groove 13, and a barrel 17 is fixedly installed around the circular groove 16 on the top of the second movable disc 11.
[0032] Furthermore, a convex block 15 is fitted on the inner wall of the convex groove 13, and a connecting column 18 is fixedly installed at the top center position of the convex block 15. The end of the connecting column 18 away from the convex block 15 passes through the circular groove 16, extends upward through the top outer surface of the barrel 17 and through the circular ring 23, and the extended end of the connecting column 18 is fixedly connected to a moving plate 20, and power columns 21 are fixedly connected to both sides of the bottom of the moving plate 20.
[0033] Furthermore, the connecting column 18 is located at the top outer surface of the inner wall of the barrel 17 and is fixedly sleeved with a third movable disc 25. A third sealing ring 26 is also fixedly installed at the middle position of the outer surface of the third movable disc 25, and the outer surfaces of the third movable disc 25 and the circular groove 16 are both slidably connected to the inner wall of the barrel 17.

The tops of the two springs 24 are fixedly connected to the bottom of the moving plate 20 , and the bottoms of the two springs 24 are fixedly connected to the top of the fixed plate 22 .
[0035] Furthermore, when in use, the worker steps on the C-shaped connecting plate 28 and applies downward force. The downward force of the C-shaped connecting plate 28 drives the two pull-down ropes 27 on the two adjusting devices to move downward. The two pull-down ropes 27 move downward and drive the two power columns 21 to move downward. The two power columns 21 move downward and drive the moving plate 20 to move downward. The moving plate 20 moves downward and causes the two springs 24 to contract. The contraction of the two springs 24 causes the moving plate 20 to move closer to the fixed plate 22. The moving plate 20 moves downward and drives the connecting column 18 to move downward. The connecting column 18 moves downward and drives the third movable disc 25 and the third sealing ring 26 to move downward. The connecting column 18 moves downward, driving the convex block 15 downward, so that the outer surface of the convex block 15 is separated from the inner wall of the convex groove 13, so that the high-pressure gas 10 exerts pressure upward, and at the same time, due to the pressure difference, the low-pressure gas 19 flows through the convex groove 13 and the circular groove 16 to the inner part of the adjusting device housing 2 located between the second movable disc 11 and the first movable disc 8, so that the second movable disc 11 is driven upward by the pressure difference, and the second movable disc 11 moves upward and finally drives the workbench 4 to move upward, and the workbench 4 moves upward to extend the four multi-stage telescopic rods 3. When the workbench 4 reaches the top, the worker stops applying force to the C-shaped connecting plate 28, so that the two The two springs 24 extend, and the two springs 24 extend to drive the moving plate 20 to move upward. The moving plate 20 moves upward to drive the connecting column 18 to move upward. The connecting column 18 moves upward to drive the convex block 15 to move upward, so that the convex block 15 enters the convex groove 13 to limit the flow of air pressure. The air pressure cannot flow and is locked. After the steel bar 7 is placed on the upper surface of the workbench 4, when the feeding device is parallel to the steel bar 7, the worker steps on the C-shaped connecting plate 28 and exerts force downward, and applies pressure to the workbench 4 through the weight of the steel bar 7. The workbench 4 is subjected to pressure and applies downward pressure to the four multi-stage telescopic rods 3, so that the bottom of the workbench 4 is aligned with the moving plate. 20 applies pressure on the top, the movable plate 20 moves downward and finally squeezes the low-pressure gas 19 between the second movable disc 11 and the first movable disc 8 of the adjusting device housing 2 into the inside of the barrel 17, so that the second movable disc 11 descends. The height of the workbench 4 can be gradually lowered according to the weight of the steel bars 7 through the adjusting device, so that workers do not need to lift the steel bars 7 one by one, thereby increasing the efficiency of cutting multiple steel bars 7. Since workers do not need to bend over to operate, they only need to step on the C-shaped connecting plate 28 when placing the steel bars 7 on the surface of the workbench 4, which makes it easier for workers to use the equipment.
[0036] Working principle: When in use, the worker steps on the C-shaped connecting plate 28 and applies downward force. The downward force of the C-shaped connecting plate 28 drives the two pull-down ropes 27 on the two adjusting devices to move downward. The two pull-down ropes 27 move downward and drive the two power columns 21 to move downward. The two power columns 21 move downward and drive the moving plate 20 to move downward. The moving plate 20 moves downward and causes the two springs 24 to contract. The contraction of the two springs 24 causes the moving plate 20 to move closer to the fixed plate 22. The moving plate 20 moves downward and drives the connecting column 18 to move downward. The connecting column 18 moves downward and drives the third movable disc 25 and the third sealing ring 26 to move downward. The connecting column 18 moves downward, driving the convex block 15 downward, so that the outer surface of the convex block 15 is separated from the inner wall of the convex groove 13, so that the high-pressure gas 10 exerts pressure upward, and at the same time, due to the pressure difference, the low-pressure gas 19 flows through the convex groove 13 and the circular groove 16 to the inner part of the adjusting device housing 2 located between the second movable disc 11 and the first movable disc 8, so that the second movable disc 11 is driven upward by the pressure difference, and the second movable disc 11 moves upward and finally drives the workbench 4 to move upward, and the workbench 4 moves upward to extend the four multi-stage telescopic rods 3. When the workbench 4 reaches the top, the worker stops applying force to the C-shaped connecting plate 28, so that the two The two springs 24 extend, and the two springs 24 extend to drive the moving plate 20 to move upward. The moving plate 20 moves upward to drive the connecting column 18 to move upward. The connecting column 18 moves upward to drive the convex block 15 to move upward, so that the convex block 15 enters the convex groove 13 to limit the flow of air pressure. The air pressure cannot flow and is locked. After the steel bar 7 is placed on the upper surface of the workbench 4, when the feeding device is parallel to the steel bar 7, the worker steps on the C-shaped connecting plate 28 and exerts force downward, and applies pressure to the workbench 4 through the weight of the steel bar 7. The workbench 4 is subjected to pressure and applies downward pressure to the four multi-stage telescopic rods 3, so that the bottom of the workbench 4 is aligned with the moving plate. 20 applies pressure on the top, the movable plate 20 moves downward and finally squeezes the low-pressure gas 19 between the second movable disc 11 and the first movable disc 8 of the adjusting device housing 2 into the inside of the barrel 17, so that the second movable disc 11 descends. The height of the workbench 4 can be gradually lowered according to the weight of the steel bars 7 through the adjusting device, so that workers do not need to lift the steel bars 7 one by one, thereby increasing the efficiency of cutting multiple steel bars 7. Since workers do not need to bend over to operate, they only need to step on the C-shaped connecting plate 28 when placing the steel bars 7 on the surface of the workbench 4, which makes it easier for workers to use the equipment.
