Description

Technical Field

[0001] The utility model relates to the field of telescopic batons, in particular to a mechanical quick telescopic baton with a steel ball locking structure. Background Art

[0002] A telescopic baton (also known as a telescopic rod) is a retractable handheld device, usually used for walking, support or self-defense. Its design allows users to adjust its length according to needs to provide appropriate support or protection in different situations. The main components of telescopic batons are usually made of lightweight metals (such as aluminum alloy) or carbon fiber, making them both strong and relatively lightweight.

[0003] When storing a telescopic baton, usually the user needs to push the top of the telescopic baton with the palm. However, the top of the telescopic baton has a small volume and exerts a large pressure on the user's palm, resulting in pain in the user's palm when storing the telescopic baton, and the storage process is relatively laborious. Or if the user doesn't want their palm to hurt, they will hold the bottom of the telescopic rod and smash the top of the telescopic rod hard against the ground or other hard objects to store the telescopic baton, but this will cause damage to the telescopic baton and reduce its service life. In view of this technical problem, this application proposes a mechanical quick telescopic baton with a steel ball locking structure. Summary of the Utility Model
