The fixing mechanism 3 also includes card slots 307 opened on the front and rear sides of the inner cavity of the shell 2.

[0026] Among them, a first rotating handle is fixed on the opposite side of the two first threaded rods 303 to facilitate the rotation of the first threaded rods 303. The clamping block 306 is slidably connected to the inside of the clamping slot 307 to limit the pressure block 301 and fix the lifting belt body 1.

[0027] In addition, two sliding rods are fixed between the left and right sides of the inner cavity of the pressing block 301, and the moving block 304 is slidably connected to the outer surface of the sliding rods, thereby increasing the stability of the moving block 304 when it moves.

[0034] (1) The shell 2 is sleeved on the outer surfaces of multiple lifting belt bodies 1, the pressure block 301 is abutted against the lifting belt body 1, and the first rotating handle is turned. The first rotating handle drives the first threaded rod 303 to rotate in the first threaded hole 302, and the moving block 304 is driven to move through the first threaded rod 303. The moving block 304 will slide on the outer surface of the sliding rod to increase the stability of the moving block 304 when moving. When the moving block 304 moves, it will drive the hinge rod 305 to rotate. The moving block 304 drives the clamping block 306 to move through the hinge rod 305, so that the clamping block 306 is clamped into the inside of the clamping groove 307, thereby squeezing and fixing the lifting belt body 1, thereby improving the strength of the lifting belt body 1.

After the lifting belt body 1 is adjusted, the second rotating handle is rotated in the opposite direction, and the second rotating handle drives the second threaded rod 503 to rotate, so that the two fixing blocks 501 are on the opposite side, and the limit block 504 will slide inside the limit groove 505, thereby increasing the stability of the fixing block 501 when moving, and fixing the lifting belt body 1 through the two fixing blocks 501 to prevent the lifting belt body 1 from loosening.
