[0025] The effect achieved by the entire embodiment 1 is that when the sealing gasket 13 needs to be disassembled, the pull handle 12 is moved inwardly to drive the telescopic rod 10 and the spring 11 to be compressed, so that the block 2 moves along the inner wall of the sliding groove 3, so that the block 2 is no longer engaged with the inner wall of the slot 18, and then the protective cover 1 is pulled upward to drive the sealing gasket 13 to be taken out from the inner side of the outer ring 4 and the inner ring 5, so that the sealing gasket 13 can be quickly taken out; when the sealing gasket 13 needs to be installed, the block 2 is aligned with the slot 18, the pull handle 12 is moved inwardly to drive the telescopic rod 10 and the spring 11 to be compressed, so that the block 2 moves along the inner wall of the sliding groove 3, and then the protective cover 1 is pressed downward. Press the protective cover 1 to install the sealing gasket 13 between the outer ring 4 and the inner ring 5, then release the handle 12, and through the restoring force of the spring 11 when it rebounds, the moving direction of the block 2 is limited by the telescopic rod 10, which will drive the block 2 to be pushed outward, so that the block 2 is engaged in the slot 18, and the installation of the protective cover 1 is completed. After the sealing gasket 13 is connected to the protective cover 1, the sealing gasket 13 is easy to install and replace, which can improve the convenience of disassembly. At the same time, after the sealing gasket 13 is installed, the first sealing ring 14 and the second sealing ring 15 will fill the first sealing groove 6 and the second sealing groove 7, thereby increasing the sealing of the bearing, and at the same time, the protective cover 1 can provide certain protection for the bearing.

[0026] Embodiment 2, as Figure 1-Figure 6 As shown, the inner walls on both sides of the two sliding grooves 3 are provided with limiting grooves 16, the outer surfaces on both sides of the two clamping blocks 2 are fixedly connected to the limiting blocks 17, the outer surfaces of the multiple limiting blocks 17 are respectively slidably arranged with the inner surfaces of the multiple limiting grooves 16, the outer surfaces of the two clamping blocks 2 are fixedly connected with the handles 12, one end of the two springs 11 is respectively fixedly connected to the inner wall of one side of the two sliding grooves 3, and the other ends of the two springs 11 are respectively fixedly connected to the outer surfaces of the two clamping blocks 2.

[0027] The effect achieved by the entire embodiment 2 is that when the block 2 moves, it will drive the limit block 17 to slide in the limit groove 16, so that the block 2 is more stable when moving. At the same time, the notch opened on the handle 12 makes it more convenient for the worker to use the handle 12, and the practicality is higher.

[0028] Working principle: when the sealing gasket 13 needs to be disassembled, the pull handle 12 is moved inward, driving the telescopic rod 10 and the spring 11 to be compressed, so that the block 2 moves along the inner wall of the sliding groove 3, and at the same time, the limit block 17 slides in the limit groove 16, so that the block 2 is more stable when moving, so that the block 2 and the inner wall of the groove 18 are no longer engaged, and then the protective cover 1 is pulled upward to drive the sealing gasket 13 to be taken out from the inner side of the outer ring 4 and the inner ring 5, and the sealing gasket 13 can be quickly taken out. When the sealing gasket 13 needs to be installed, the block 2 is aligned with the groove 18, and the pull handle 12 is moved inward, driving the telescopic rod 10 and the spring 11 to be compressed, so that the block 2 moves along the inner wall of the sliding groove 3. The wall is moved, and then the protective cover 1 is pressed downward to install the sealing gasket 13 between the outer ring 4 and the inner ring 5, and then the handle 12 is released. The restoring force of the spring 11 when it rebounds limits the moving direction of the block 2 through the telescopic rod 10, thereby driving the block 2 to be pushed outward, so that the block 2 is engaged in the slot 18, and the installation of the protective cover 1 is completed. After the sealing gasket 13 is connected to the protective cover 1, the sealing gasket 13 is easy to install and replace, which can improve the convenience of disassembly. At the same time, after the sealing gasket 13 is installed, the first sealing ring 14 and the second sealing ring 15 will fill the first sealing groove 6 and the second sealing groove 7 to increase the sealing of the bearing. At the same time, the protective cover 1 can provide certain protection for the bearing.
