AI Technical Summary
Technical Problem
Existing pullers require adjustment of multiple claw positions after assembly according to the diameter of the bearing or gear, resulting in uneven force during the pulling process, which may damage the bearing or gear.
Method used
It adopts an internal threaded column and threaded drive rod structure, combined with a quick-assembly combination mechanism and a synchronous positioning and adjustment steering mechanism, to achieve synchronous adjustment of the angle and position of the three sets of long-handled claws, ensuring uniform force distribution.
Benefits of technology
This ensures uniform force distribution on bearings or gears during the drawing process, preventing damage to parts and improving the practicality and reliability of the drawing device.
