The top of the movable receiving groove 3 of the fixed frame 2 2 is also fixedly connected to the sleeve 2 13, and the sleeve 2 13 is plugged and fixed to the connecting end 2 11.

[0050] The connecting end 12 includes a connecting shaft 18 fixedly connected to the winding rod 5, and a sleeve 3 17 is sleeved on the outside of the connecting shaft 18, a coil spring 19 is arranged between the sleeve 3 17 and the connecting shaft 18, and the coil spring 19 is sleeved on the outside of the connecting shaft 18, one end of the coil spring 19 is fixed to the connecting shaft 18, and the other end is fixed to the inner wall of the sleeve 3 17.

[0051] A rotating groove 20 of an annular structure is provided at one end of the retracting rod 5, and a rotating block 21 is movably connected inside the rotating groove 20. The rotating block 21 is fixedly connected to the sleeve three 17, and the rotating block 21 and the rotating groove 20 cannot be separated.

[0053] The sleeve 1 8 is inserted into the sleeve 2 13 inside the movable receiving groove 3 in the fixed frame, and a bearing is provided between the sleeve 1 8 and the sleeve 2 13 for rotational connection, and the bearing is fixed to the inner wall of the sleeve 2 13 .

[0054] Working principle: When working, first place the fixing frame 1 and the fixing frame 2 2 in the corresponding positions, then hold the connecting end 2 11 of the winding rod 5, flip the winding rod 5 out of the movable receiving slot 3 in the fixing frame 1, and then insert the connecting end 2 11 into the sleeve 2 13 at the top of the movable receiving slot 3 in the fixing frame to rotate and connect through the bearing, then separate the cross bar 6 from the winding rod 5, insert the two ends of the winding rod 5 into the movable receiving slot 3 through the slider 7, and then the user Water is injected into the water storage chamber 22 in the cross bar 6 through the valve 23 connected to the outside of the cross bar 6. As the water in the water storage chamber 22 increases, the weight of the cross bar 6 increases. At this time, the cross bar 6 slides downward along the movable storage groove 3 through the slider 7, pulling and pulling the shielding mesh 4. At this time, the shielding mesh 4 is driven to unfold outside the retracting rod 5 and pull the retracting rod 5 to rotate. The rotation of the retracting rod 5 will drive the connecting shaft 18 to rotate inside the sleeve three 17 to elastically accumulate potential for the coil spring 19, and the sleeve one 8 in the connecting end two 11 is also driven by the shaft The bearing and sleeve 2 13 rotate until the cross bar 6 moves to the bottom of the movable storage groove 3. At this time, the shielding mesh 4 in the unfolded state cooperates with the fixing frame 1 and the fixing frame 2 2 on both sides to form a fence to protect the surrounding of the lifting equipment. When the device is not in use, the water in the water storage chamber 22 is drained through the valve 23. As the water source is lost, the weight of the cross bar 6 is reduced. Under the action of the winding spring 19, the winding rod 5 is driven to rotate in the opposite direction, the shielding mesh 4 is wound up, and the migration pulls the cross bar 6 to move up through the slider 7 to the movable storage groove 3 until the cross bar 6 is on The arc-shaped surface at the end fits the outside of the retracted rod 5 that wraps the retracted shielding mesh 4, and then the user removes the connecting end 2 11, and through the rotating structure at the connecting end 12, the retracted rod 5, the shielding mesh 4 and the cross bar 6 are stored in the movable storage groove 3, and then elastically squeezed by the spring 10 between the sleeve 1 8 and the connecting rod 9, it reaches the bottom end of the movable storage groove 3 and is fixed in the movable storage groove 3 in the fixing frame 1, and then the fixing frame 1 1 and the fixing frame 2 2 are magnetically spliced ​​and connected to facilitate subsequent transportation by users.
