[0002] Actuators are widely used in the aviation field. Their principle is to generate rotational force through motors, which is converted and transmitted through reducers and transmission devices to enable the load to move. Since the internal spindle components of most actuators are equipped with mechanical parts such as embedded balls, in order to facilitate regular maintenance and replacement of the spindles and other parts, the embedded balls and other mechanical parts need to be removed.

[0003] Since the mandrel of a general actuator is relatively long, it cannot be pressed using a conventional press table and press sleeve. In addition, the press sleeve will block the mandrel, making it impossible to remove the embedded components in the mandrel. In addition, the press table is placed in a fixed position, so the disassembly and assembly of the mandrel assembly consumes a lot of man-hours.

[0004] Therefore, in order to facilitate the removal of the embedded ball in the core shaft of the rotary actuator, it is necessary to develop a small size, light weight, easy to carry, easy to use, and widely inclusive rotary actuator core shaft embedded ball removal tool. Utility Model Content
