The disc block 2 is located on the lower side of the cylindrical shaft block 1. A bearing block 3 is fixedly connected to the outer side of the cylindrical shaft block 1. A threaded hole 4 is opened on the upper side of the disc block 2. A threaded rod 5 is installed inside the threaded hole 4. A control block 6 is fixedly connected to the lower end of the threaded rod 5. An adjustment structure 7 is provided on the upper side of the disc block 2. A reinforcing structure 8 is provided on the outer side of the adjustment structure 7. The threaded rod 5 and the disc block 2 are threadedly connected. The adjustment structure 7 includes a groove 701. The groove 701 is opened on the upper side of the disc block 2. There are three grooves 701. A moving block 702 and a spring 703 are installed inside the groove 701. A clamping block 704 is fixedly connected to the upper side of the moving block 702. A limiter is fixedly connected to the upper side of the clamping block 704. Block 705, the outer side of the disc block 2 has three circular holes 706. A pull rod 707 is installed inside each circular hole 706. One end of the pull rod 707 passes through a spring 703 and is fixedly connected to a moving block 702. The other end of the pull rod 707 is fixedly connected to a cylindrical block 708. The pull rod 707 and the disc block 2 are slidably connected. A groove 701 has two sliding grooves 709. A slider 710 is installed inside each sliding groove 709. One end of the spring 703 is fixedly connected to the disc block 2, and the other end is fixedly connected to the moving block 702. The moving block 702 and the disc block 2 are slidably connected. A clamping block 704 is movably connected to a bearing block 3. A limiting block 705 is slidably connected to a bearing block 3. Block 710 and disc block 2 are slidably connected, slider 710 and moving block 702 are fixedly connected, and the reinforcing structure 8 includes a second slide groove 801, which is opened on the outside of clamping block 704. Inside the second slide groove 801 are spring 802 and slider 803. A pressing block 804 is fixedly connected to the outside of slider 803, and the pressing block 804 and bearing block 3 are slidably connected. The upper end of spring 802 is fixedly connected to clamping block 704, and the lower end of spring 802 is fixedly connected to slider 803. Sliding block 803 and clamping block 704 are slidably connected. The operator prepares to clamp and fix the bearing block 3 on the cylindrical block 1. First, the cylindrical block 708 is pulled, causing the pull rod 707 to slide, which in turn causes the moving block 702 and... The slider 710 of the moving block 702 compresses the spring 703, causing the moving block 702 to move the clamping block 704, the limiting block 705, and the reinforcing structure 8. Then, the operator pushes the pressing block 804, which in turn causes the slider 803 to move while the spring 802 is stretched. The operator then slowly loosens the cylindrical block 708, allowing the limiting block 705 and the clamping block 704 to clamp and fix the bearing block 3. The pressing block 804 is then released, allowing it to clamp and fix the bearing block 3 again under the action of the spring 802. The other two clamping blocks 704, the limiting block 705, and the pressing block 804 are operated in the same way, thus fixing the bearing block 3. The adjusting structure 7 allows the operator to clamp and fix bearings of different sizes.Then, bearing block 3 is removed, saving workers the trouble of changing bearing disassembly devices according to different bearing sizes. This is time-saving, labor-saving, convenient, and quick. At the same time, the reinforcing structure 8 can provide secondary clamping and fixation of bearing block 3, preventing the internal parts from falling apart when bearing block 3 is removed.

[0026] Working principle: When disassembling bearing block 3, the operator first uses the adjusting structure 7 to clamp and fix bearing block 3 according to its size. Then, the reinforcing structure 8 clamps and fixes bearing block 3 again. After that, the operator holds the control block 6 and rotates it. The control block 6 drives the threaded rod 5 to rotate on the disc block 2. Then, the threaded rod 5 presses against one end of the round shaft block 1. Rotating the threaded rod 5 again will cause the disc to move the bearing block 3 clamped by the adjusting structure 7 and the reinforcing structure 8. Finally, the bearing block 3 can be removed without falling and being damaged. The adjusting structure 7 allows the device to disassemble bearing blocks 3 of different sizes, saving the operator the workload of changing disassembly devices, making it convenient and quick.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
