DETAILED DESCRIPTION
[0017] Example, by Figure 1-2The utility model includes a cylinder 1, and the left and right sides of the cylinder 1 are both driven and connected with square driving rollers. The cylinder 1 is rotatably connected with a rotating frame 11 through the square driving roller. A fixed mounting seat 2 is fixedly installed on the side of the cylinder 1, and a connecting frame 3 is fixedly installed on the side of the fixed mounting seat 2. A second clamping jaw 5 is fixedly installed on the top of the rotating frame 11, and a first clamping jaw 4 is movably connected to the bottom of the connecting frame 3. The bottom surface of the first clamping jaw 4 is in contact with the top surface of the second clamping jaw 5. A gasket 6 is padded between the contact surface of the rotating frame 11 and the second clamping jaw 5. The top of the fixed mounting seat 2 is connected to the main frame of the sling. The bottom end of the connecting frame 3 is integrally formed with a first mounting plate 31 and a second mounting plate 32, and a groove 33 is formed between the first mounting plate 31 and the second mounting plate 32. A first mounting column 41 is fixedly installed on the top of the first mounting column 41, a second mounting column 42 is fixedly installed on the top of the first mounting column 41, a threaded column 43 is fixedly installed on the top of the second mounting column 42, and a nut 44 is threadedly installed on the surface of the threaded column 43. The first mounting column 41 is movably installed in the second mounting plate 32, the threaded column 43 is movably installed in the first mounting plate 31, the nut 44 is movably installed on the top of the first mounting plate 31, the surface of the second mounting column 42 is movably sleeved with a mounting sleeve 45, the surface of the mounting sleeve 45 is movably sleeved with a spring 46, the top surface of the mounting sleeve 45 is fitted with the bottom surface of the first mounting plate 31, the bottom of the spring 46 is fitted with the top surface of the first mounting column 41, and the side surface of the first clamp 4 is fitted with the side surface of the connecting frame 3.
