The pressing top 33 is arranged at the end far from the convex block 32, and the pressing top 33 can press both ends of the flexible belt 2 on the outer surface of the wheel wall 11.

[0047] The second locking member includes a plug-in part 4. A slot 44 is formed in the plug-in part 4. The plug-in part 4 can be plugged onto the insertion block 31 through the slot 44, and the plug-in part 4 can be clamped between the convex block 32 and the inner surface of the wheel wall 11 of the roller body 1; preferably, the shape of the slot 44 is the same as that of the long hole 12. When the plug-in part 4 is connected to the insertion block 31, the slot 44 and the long hole 12 can be strictly aligned.

[0048] Working principle: Wrap the flexible belt 2 around the wheel wall 11 of the roller body 1, so that both ends of the flexible belt 2 extend into the long hole 12 on the wheel wall 11. Then insert the first locking member 3 into the long hole 12. The insertion block 31 of the first locking member 3 is inserted into the long hole 12. The insertion block 31 can squeeze the end part of the flexible belt 2 to a certain extent. At the same time, the pressing top 33 of the first locking member 3 presses the end part of the flexible belt 2 against the surface of the wheel wall 11. In this way, the two end parts of the flexible belt can be locked in the long hole 12 through the first locking member 3. Then, plug the slot 44 of the plug-in part 4 of the second locking member onto the insertion block 31 of the first locking member 3. The plug-in part 4 can be clamped between the convex block 32 and the inner surface of the wheel wall 11 of the roller body 1. The first locking member 3 can be locked on the roller body 1 through the plug-in part 4, so as to form a stable locking structure, ensuring that the two end parts of the flexible belt 2 can be stably locked in the long hole 12 of the wheel wall 11, fundamentally avoiding the technical problem that the end parts of the flexible belt 2 on the roller body 1 are prone to warping.

[0049] In one embodiment, the plug 4 is a cylindrical structure. Preferably, the size of the plug 4 matches the size of the roller body 1. When the plug 4 is inserted into the interior of the roller body 1, the outer wall of the plug 4 fits against the inner wall of the roller body 1.
