When the sliding sleeve 4 rotates, the screw rod 3 is driven to rotate on its surface, a turning handle 5 is fixedly installed at one end of the bottom plate 1, one end of the turning handle 5 passes through the bottom plate 1 and is fixedly connected to one end of the screw rod 3, and when the turning handle 5 rotates, the screw rod 3 is driven to rotate, and a vertical rod 6 is fixedly installed on the top of the bottom plate 1 and the cross plate 2, and a round shaft 7 is fixedly installed inside the vertical rod 6, and a moving block 8 is movably sleeved on the surface of the round shaft 7, and the inner surface of the moving block 8 and the outer surface of the round shaft 7 are both smooth, so that the moving block 8 can slide on the surface of the round shaft 7 more smoothly. The sliding block 8 is hinged with a movable rod 11, and when the slider 10 slides on the surface of the round rod 9, it will push the movable rod 11 to slide, and a movable rod 12 is hinged between the sliding sleeve 4 and the movable block 8. A fixed rod 19 is fixedly installed on one end of the sliding sleeve 4, and a square rod 20 is fixedly installed on one side of the slider 10. A bolt 21 is rotatably installed on the top of the square rod 20, and the bottom of the bolt 21 passes through the square rod 20 and extends to the inside of the fixed rod 19. The bolt 21 can be turned and screwed into the inside of the fixed rod 19 and the square rod 20 to connect them, thereby connecting the sliding sleeve 4 to the slider 10.

[0021] The opposite surfaces of the moving block 8 are hinged with a lifting plate 13 and a connecting plate 14, respectively. A connecting rod 15 is rotatably installed on the top of the connecting plate 14, and the bottom of the connecting rod 15 penetrates the lifting plate 13 and the connecting plate 14 and extends to the bottom of the connecting plate 14. Rotate the connecting rod 15 and screw it into the inside of the lifting plate 13 and the connecting plate 14 to connect them. A movable plate 16 is hinged on one side of the bottom plate 1 and the vertical rod 6, and a movable plate 17 is hinged on one side of the horizontal plate 2 and the vertical rod 6. A locking rod 18 is rotatably installed on the top of the movable plate 17, and the bottom of the locking rod 18 penetrates the movable plate 16 and the movable plate 17 and extends to the bottom of the movable plate 17.

The opposite surfaces of the bottom plate 1 and the horizontal plate 2 are fixedly installed with a fixed plate 22, and the inside of the fixed plate 22 is rotatably installed with a ground nail 23. Due to the design of the fixed plate 22 and the ground nail 23, the fence can be fixed to make it more stable.

[0022] Working principle: When the protective fence needs to be installed and used, the operator first moves the horizontal plate 2, at which time the horizontal plate 2 will drive the round rod 9 and the slider 10 to slide synchronously. When one side of the square rod 20 reaches one side of the fixed rod 19, the bolt 21 is turned and screwed into the fixed rod 19 and the square rod 20. Secondly, when the horizontal plate 2 moves, it will drive the vertical rod 6, the round shaft 7 and the moving block 8 to slide synchronously, and then the lifting plate 13 and the connecting plate 14, the movable plate 16 and the moving plate 17 will contact each other, and then the connecting rod 15 and the locking rod 18 are turned and screwed into the lifting plate 13 and The connecting plate 14, the movable plate 16 and the movable plate 17 can be connected to each other inside. When the height of the protective fence needs to be adjusted, the operator turns the handle 5. The rotation of the handle 5 will cause the screw 3 to rotate, which will drive the fixed rod 19 and the square rod 20 to slide synchronously, and then drive the slider 10 to slide synchronously on the surface of the round rod 9. At the same time, the sliding sleeve 4 and the slider 10 will push the movable rod 12 and the movable rod 11 to slide, and then drive the movable block 8 to rise and fall on the surface of the circular shaft 7, thereby driving the lifting plate 13 and the connecting plate 14 to rise and fall, and the height of the protective fence can be adjusted.
