[0028] The four blocks 4 are arranged in an L shape, and the telescopic rod 6 is located inside the spring 7;

[0029] The L-shaped arrangement enables the block 4 to better support the flywheel housing body 13;

[0030] The opposite sides of the two springs 7 are fixedly connected with a force guide block 8, and the bottoms of the two force guide blocks 8 are fixedly connected with a closing handle 10;

[0031] By closing the handle 10, the force guide block 8 can be easily retracted;

[0032] The left end of the left threaded rod 3 is fixedly connected with a first turning handle 11, and the back of the back threaded rod 3 is fixedly connected with a second turning handle 12;

[0038] Working principle:

[0039] The first step: put the flywheel housing body 13 through the vertical block 5, so that the limit block 9 plays the first limiting role on the flywheel housing body 13, then turn the first handle 11, so that the first handle 11 drives the left threaded rod 3 to rotate, and the left threaded rod 3 drives the right threaded rod 3 to rotate through the top rotating shaft 2, so that the blocks 4 on the left and right sides are closed, and then turn the second handle 12, so that the second handle 12 drives the back threaded rod 3 to rotate, and the back threaded rod 3 drives the front threaded rod 3 to rotate through the bottom rotating shaft 2, so that the front and back blocks 4 are closed, so that the flywheel housing body 13 is limited for the second time;

[0040] Step 2: When the flywheel housing body 13 needs to be disassembled, the first turning handle 11 and the second turning handle 12 are rotated in reverse to open the four blocking blocks 4, and then the closing handle 10 is closed to the opposite side, so that the two closing handles 10 drive the force guiding blocks 8 to close, and then the two force guiding blocks 8 drive the limit blocks 9 to move, so that the vertical block 5 can pass through the flywheel housing body 13, thereby completing the unloading.
