[0025] Specifically, the through groove 13 is used to provide a passing space for the first blocking block 8, and the first spring 12 is used to move and reset the second round block 10. When the second round block 10 is subjected to force, the first spring 12 will slide on the outer wall of the sliding column 9 and shrink, thereby the second round block 10 can be moved. When the second round block 10 is no longer subjected to force, the first spring 12 will rebound and reset, thereby the second round block 10 can be reset.

[0026] Reference Figure 3 The outer wall of the flat belt 1 is slidably connected with a semi-cylinder 16, one end of the semi-cylinder 16 is fixedly connected with a first disc 17, and the outer wall of the semi-cylinder 16 is provided with a second slot 18;

[0027] Specifically, the first disc 17 can play a role in fixing the semi-cylinder 16 in a movable manner.

[0028] Reference Figure 1 , Figure 3 and Figure 4 The outer wall of the semi-cylinder 16 is slidably connected with a second disc 19, one end of the second disc 19 is provided with a rectangular groove 20, the inner wall of the second disc 19 is provided with a circular groove 21, and the interior of the second disc 19 is fixedly connected with a second spring 22; one end of the second spring 22 is fixedly connected with a slider 23, the outer wall of the slider 23 is slidably connected to the inner wall of the circular groove 21, and the end of the slider 23 away from the second spring 22 is fixedly connected with a connecting column 24, the outer wall of the connecting column 24 is fixedly connected with a pulling column 25, the outer wall of the pulling column 25 is slidably connected to the inner wall of the rectangular groove 20, and the outer wall of the connecting column 24 is provided with an inner groove 26; the interior of the second disc 19 is fixedly connected with a limiting column 27, and the outer wall of the limiting column 27 is slidably connected to the inner wall of the inner groove 26; the end of the connecting column 24 away from the slider 23 is fixedly connected with a second clamping block 28; the outer wall of the second clamping block 28 is slidably connected to the inner wall of the second clamping groove 18;

[0029] Specifically, the rectangular groove 20 can provide space for the pulling column 25 to move. The pulling column 25 is used to disassemble the second disc 19 and the semi-cylinder 16. Pulling the pulling column 25 prompts the connecting column 24 to drive the second block 28 to slide out from the inner wall of the second slot 18, thereby releasing the fixed state of the second disc 19 and the semi-cylinder 16. The limiting column 27 is used to limit the movement of the connecting column 24.

[0030] Working principle: when it is necessary to adjust the size of the lower eyelet 2, it is only necessary to first pass the short column 7 together with the first clamping block 8 through the first circular hole 3 and the second circular hole 4 at the same time, and then prompt the first clamping block 8 to slide on the outer wall of the through groove 13. When the first clamping block 8 slides through the outer wall of the through groove 13, the end of the short column 7 away from the first round block 5 will fit with the end of the second round block 10 away from the sliding column 9, and then continue to push the first round block 5 to drive the short column 7 to move, prompting the second round block 10 to move and push the sliding column 9 to slide inside the cylinder 6. At the same time, the first spring 12 will be forced to slide on the outer wall of the sliding column 9 and shrink, and then rotate the first round block 5 to cause it to rotate ninety degrees, and then no longer push the first round block 5, thereby prompting the first spring 12 to rebound and reset, pushing the short column 7 to drive the first clamping block 8 to slide on the outer wall of the first clamping slot 14, thereby completing the adjustment of the size of the lower eyelet 2, thereby achieving the effect of adjusting the size of the lower eyelet 2, thereby ensuring that the sling can be connected with different sizes and types. The second spring 22 is tightly coupled to the slider 23 and the fixing device 24, so as to enhance the safety of lifting and improve the convenience of operation. When it is needed to be stored, it is only necessary to slide the semi-cylinder 16 on the outer wall of the flat belt 1, and then slide the second disc 19 on the outer wall of the semi-cylinder 16. During the sliding process, the second clamping block 28 will be forced to move, and then the connecting column 24 can be pushed to move upward, so that the slider 23 slides on the inner wall of the circular groove 21 and causes the second spring 22 to be forced to contract. When the second clamping block 28 slides into the inner wall of the second clamping groove 18 opened on the outer wall of the semi-cylinder 16, the second clamping block 28 will no longer be subjected to force at this time, and then the second spring 22 will rebound and push the slider 23 to slide downward, push the connecting column 24 to drive the second clamping block 28 to completely slide into the inner wall of the second clamping groove 18, and then the second disc 19 can be fixed. At this time, the flat belt 1 can be rolled up, which is convenient for its storage, thereby taking up less storage space and protecting the sling from excessive bending.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
