A third fixing hole 608 is provided on one side of the block 604, a second sliding groove 609 is provided on one side of the first sliding block 604, a second sliding block 610 is slidably connected to the surface of the second sliding groove 609, a fourth fixing hole 611 is provided on one side of the second sliding block 610, a second bolt 612 is movably sleeved on the surface of the fourth fixing hole 611, and a barb 613 is fixedly connected to one side of the second sliding block 610. During use, when the roller sleeve needs to be hoisted, the first sliding block 604 can be slid to the required position in the first sliding groove 601 in advance according to the length of the roller sleeve, and then the first sliding block 604 is fixed to the first fixing rod 503 with the first bolt 607, so that the roller sleeve automatic tension clamp can adapt to roller sleeves of different lengths. At the same time, the barb 613 can also be replaced or disassembled through the second bolt 612, thereby improving the use efficiency of the roller sleeve automatic tension clamp.

[0023] Furthermore, the second fixing holes 606 are arranged in six groups, and the first fixing rod 503 and the first sliding block 604 are movably connected with the first bolt 607. By setting the six groups of second fixing holes 606, the automatic roller sleeve tension clamp can be better adapted to roller sleeves of different lengths, thereby improving the adaptability of the automatic roller sleeve tension clamp.

Through the arrangement of the limiting strip 605 and the limiting groove 602, the barb 613 can be replaced or disassembled, thereby avoiding the possibility of scratches on the roller sleeve when the roller sleeve is hoisted by the automatic tension clamp of the roller sleeve.

[0025] Working principle: During use, when the roller sleeve needs to be hoisted, the roller sleeve automatic tension clamp can be connected to the lifting equipment through the lifting ring 3. After the specific size of the roller sleeve is determined in advance, the roller sleeve automatic tension clamp is lifted and the ends of the four groups of first fixing rods 503 are extended into the inner wall of the roller sleeve, thereby completing the first step of positioning the roller sleeve and facilitating the subsequent fixation of the roller sleeve. Through the arrangement of the first fixing rod 503, the first rotating groove 501, the first transmission block 502 and the fixing frame 1, the first fixing rod 503 can be rotated in the inner wall of the roller sleeve, which is beneficial to the fixing effect of the roller sleeve automatic tension clamp on the roller sleeve. Through the second fixing rod 509, the first rotating groove 501, the first transmission block 502 and the fixing frame 1, the roller sleeve automatic tension clamp can be used to fix the roller sleeve. The arrangement of the second rotating groove 507, the second transmission block 508 and the connecting block 506 allows the connecting block 506 to limit the second fixed rod 509 to a certain extent, which is beneficial to the overall fixation of the roller sleeve by the automatic roller sleeve tension clamp. According to the length of the roller sleeve, the first sliding block 604 can be slid to the required position in the first sliding groove 601 in advance, and then the first sliding block 604 and the first fixed rod 503 are fixed with the first bolt 607, so that the automatic roller sleeve tension clamp can adapt to roller sleeves of different lengths. At the same time, the barb 613 can also be replaced or disassembled through the second bolt 612, which greatly improves the efficiency of the roller sleeve lifting equipment.
