AI Technical Summary

Problems solved by technology

Although it can automatically open and close the umbrella, its control device has a complicated structure. When pressing down to open the umbrella, it needs to overcome the torsional force of the torsion spring, which leads to a large pressing force when in use, and because the buckle head The oblique fastening on the horizontal hole makes it not smooth enough when sliding, which is not only not conducive to the opening of the umbrella, but also causes greater vibration in the handle. It is necessary to use more force to press the pressing plate and when the outer tube is received, more force is needed to overcome the elastic force of the spring sheet, which is not conducive to the user's use
