AI Technical Summary
Existing hydraulic device oil seal installation tools have a limited range of applications, require multiple workpieces of different sizes, are cumbersome to operate, and are difficult to adapt to hydraulic rods of different specifications.
It adopts a skeleton body that can be bent into a ring or fan-shaped shape, and is connected by multiple arranged ribs and pins. The bottom of the ribs is equipped with a plug block, which is suitable for hydraulic rods of different diameters. The sealing gasket is pushed into the gap by manual operation.
It achieves hydraulic rods suitable for different diameters, is easy to operate, eliminates the need for tools such as rubber hammers, and improves installation efficiency and applicability.
