[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention uses a clamping component to hold the outer circumference of the bearing, and a rotating seat to abut the end of the conveyor roller. Rotating the lever causes the bearing to move relative to the conveyor roller, thus disengaging it. This disassembly process is simple and convenient, without damaging the bearing or the conveyor roller. The clamping component is movable and uses the spring force to hold the bearing, making the device suitable for disassembling bearings of different sizes. A magnet is provided at the bottom of the rotating seat; during disassembly, the magnet attracts the end of the conveyor roller to facilitate the positioning of the rotating seat. Furthermore, reinforcing ribs and triangular reinforcing plates are provided on the clamping component to increase its strength. Attached Figure Description
