[0028] A worm wheel 9 is fixedly sleeved on the rotating shaft 4. A worm 10 is rotatably arranged in the connecting frame 1 through a bearing. The worm 10 is meshed with the worm wheel 9. A rotating rod 11 is fixedly arranged at one end of the worm 10. The rotating rod 11 is rotatably inserted in the connecting frame 1 through a bearing. An adjusting limit mechanism 12 is provided on the rotating rod 11.

[0029] The adjustment and limiting mechanism 12 comprises:

[0030] A movable rod 12-1, wherein the movable rod 12-1 is movably arranged in the rotating rod 11, and a plurality of movable bars 12-2 are fixed by bolts at equal fillet angles on the ring side wall of the movable rod 12-1, and the movable bars 12-2 are movably arranged in movable grooves provided on the inner wall of the rotating rod 11;

[0031] A control rod 12-3, wherein the control rod 12-3 is fixedly arranged at one end of the movable rod 12-1, and the control rod 12-3 is movably arranged on the movable rod 12-1, and a spring 12-4 is movably sleeved on the control rod 12-3, and the two ends of the spring 12-4 are respectively connected to the movable rod 12-1 and the inner wall of the rotating rod 11;

[0032] The control handle 12-5 is fixedly provided at one end of the control rod 12-3 by bolts. The control handle 12-5 and the side wall of the connecting frame 1 are both bonded and fixed with rubber rings 13. The two rubber rings 13 are arranged in abutment with each other. The thrust applied by the spring 12-4 to the movable rod 12-1 can make the control rod 12-3 drive the control handle 12-5 and the supporting frame to squeeze each other and generate a force to avoid the control rod 12-3, the control handle 12-5 and the movable rod 12-1 from rotating during the installation of the bearing. At the same time, the cooperation of the two rubber rings 13 can further improve the friction generated between the control handle 12-5 and the supporting frame.

[0033] When using the utility model, the control handle 12-5 is moved away from the connecting frame 1, so that the two rubber rings 13 are separated from each other, and at the same time, the control handle 12-5 drives the movable rod 12-1 to move in the direction of the spring 12-4 through the control rod 12-3, so that the spring 12-4 is compressed, and then the control handle 12-5 can be rotated, the control handle 12-5 drives the control rod 12-3 to rotate, the control rod 12-3 drives the movable rod 12-1 to rotate, the movable rod 12-1 drives the rotating rod 11 to rotate through the movable bar 12-2, the rotating rod 11 drives the worm 10 to rotate, the worm 10 drives the worm wheel 9 to rotate, the worm wheel 9 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the rotating disk 5 to rotate The guide block 7 moves in the arc guide groove 6, thereby driving the cross bar 2, the vertical bar 3 and the resistance block 8 to move, so as to realize the synchronous and equidistant adjustment of several resistance blocks 8 from the center of the connecting frame 1 according to the size of the bearing, and then release the control handle 12-5. At this time, the spring 12-4 resets and stretches, pushing the movable rod 12-1 in the opposite direction of the spring 12-4. The movable rod 12-1 drives the control handle 12-5 to move toward the support frame through the control rod 12-3, so that the two rubber rings 13 collide with each other and generate a large friction force, and then the resistance block 8 is abutted against the inner ring or outer ring of the bearing, and then the connecting frame 1 is knocked downward with a hammer to realize the installation of the bearing.

[0034] After adopting the above structure, the beneficial effects of this specific implementation are as follows:

[0035] 1. Through the cooperation of the rotating shaft 4, the rotating disk 5, the guide block 7, the contact block 8, the worm wheel 9, the worm 10 and the rotating rod 11, the distance between the several contact blocks 8 can be adjusted according to the different sizes of the bearings, thereby fully expanding the scope of application and improving the convenience of use;

[0036] 2. By adjusting the cooperation between the limit mechanism 12 and the rubber ring 13, the phenomenon of the control rod 12-3, the control handle 12-5 and the movable rod 12-1 rotating randomly due to vibration caused by knocking can be avoided during the installation of the bearing.
