[0049] The fixing rod 3 and the slider 4 are set to be slidingly connected, and two groups of sliders 4 are symmetrically arranged on the outer wall of the fixing rod 3, and the outer wall of the slider 4 fits with the inner wall of the lifting plate 2. The above structural design adjusts the spacing by sliding the two groups of sliders 4 on the outer wall of the fixing rod 3, so as to facilitate adjustment according to the length of the profile, thereby improving the lifting stability.

[0050] The outer wall of the rotating shaft 6 is symmetrically provided with positive and negative threads, and the outer wall of the rotating shaft 6 is symmetrically provided with two groups of movable plates 8, and the rotating shaft 6 and the movable plates 8 are arranged to be threadedly connected, and the inner wall of the inner groove 5 is in contact with the outer wall of the movable plates 8. The above structural design enables the rotating shaft 6 to rotate and drive the two groups of movable plates 8 to move toward each other, and the movable plates 8 are in contact and slide in the inner groove 5 to limit the position.

[0051] The fixing plate 9 and the positioning block 10 are set to be slidingly connected, one end of the No. 1 spring 12 is fixedly connected to the bottom end of the fixing plate 9, and the other end of the No. 1 spring 12 is fixedly connected to the top of the pressure block 11, the bottom end of the positioning block 10 is set to a conical structure, and the top outer wall of the positioning block 10 fits with the inner wall of the positioning groove 13, and the bottom end of the fixing rod 3 is equidistantly provided with positioning grooves 13.

[0052] The sling structure 14 includes a hook 1401, a movable groove 1402, a movable rod 1403 and a No. 2 spring 1404. The bottom end of the slider 4 is rotatably connected to the hook 1401. A movable groove 1402 is provided inside the hook 1401. A movable rod 1403 is provided inside the movable groove 1402. The inner wall of the movable groove 1402 and the outer wall of the movable rod 1403 are fixedly connected with the No. 2 spring 1404. The above-mentioned structural design lifts and transports the profile through the sling structure 14, and limits it through the movable rod 1403.

[0053] The movable groove 1402 and the movable rod 1403 are set to be slidingly connected, and the movable groove 1402 and the movable rod 1403 are both set to an arc structure. The above structural design allows the movable rod 1403 to slide inside the movable groove 1402, thereby facilitating the staff to lift the profile while limiting it through the movable rod 1403.

[0054] Working principle: According to Figure 1-3 When the two sets of slide blocks 4 are lifted, the two sets of slide blocks 4 slide on the outer wall of the fixed rod 3. After the spacing between the two sets of slide blocks 4 is adjusted, the knob 7 is turned, and the knob 7 drives the rotating shaft 6 to rotate. The rotating shaft 6 causes the two sets of movable plates 8 to move toward each other through the positive and negative threads on the outer wall. The two sets of movable plates 8 squeeze the bottom ends of the positioning blocks 10, and the positioning blocks 10 slide in the fixed plate 9, and the positioning blocks 10 drive the pressure blocks 11 to squeeze the No. 1 spring 12, and the top end of the positioning blocks 10 is stuck in the corresponding positioning groove 13 at the bottom end of the fixed rod 3, thereby positioning the slide blocks 4. When the rotating shaft 6 is reversed and drives the two sets of movable plates 8 to move away from each other, the No. 1 spring 12 recovers its deformation, causing the pressure blocks 11 to drive the positioning blocks 10 to slide out of the positioning groove 13 at the bottom end of the fixed rod 3, thereby facilitating the adjustment of the spacing between the slide blocks 4 according to profiles of different lengths, thereby improving the lifting stability. Figure 1 and Figure 4 As shown, in the process of lifting the profile, the movable rod 1403 is first pressed to slide in the movable groove 1402, and the movable rod 1403 squeezes the No. 2 spring 1404. At this time, the opening of the hook 1401 is opened to hook the lifting point of the profile, and then the movable rod 1403 is released, and the No. 2 spring 1404 recovers its deformation and drives the movable rod 1403 to slide and reset in the movable groove 1402, and the hook 1401 can be rotated to adjust the angle. When the profile shakes during the lifting and transportation process, the movable rod 1403 is used to limit it, thereby avoiding unhooking during transportation, thereby improving safety.
