- Expandable batons are widely used by law enforcement personnel or as a personal protection means. A conventional expandable baton comprises a plurality of telescopic tubes is shown in
FIGS. 6 and 7 . The baton is expandable between an extended position and a retracted position (seeFIGS. 6 and 7 ). As shown, asmaller tube 60 is partially retracted into alarger tube 62. At the extended position, thesmaller tube 60 extends out of an end of thelarger tube 62 and is locked. As an end, the baton is expanded. - However, an
annular groove 64 is required to form on an inner surface of thelarger tube 62 for locking thesmaller tube 60 in thelarger tube 62 and thelarger tube 62 is required to have an increased wall thickness for the forming of theannular groove 64. Thus, a sufficient space is provided for the forming of theannular groove 64. Unfortunately, the greater wall thickness of thelarger tube 62 can greatly increase its weight and make manufacturing more difficult. Further, a frequent retraction and extension of thesmaller tube 60 relative to thelarger tube 62 can greatly, quickly wear the inner surface of thelarger tube 62. Thesmaller tube 60 cannot be stably disposed in the wornlarger tube 62. - Thus, the need for improvement still exists.
- It is therefore one object of the invention to provide an expandable baton comprising a first tube including internal threads on an inner surface of a second end; a second tube; a first inner support tube having a diameter less than that of the first tube, the first inner support tube including first external threads on an outer surface, the first external threads being secured to the internal threads of the first tube; a second inner support tube having a diameter less than that of the first tube, the second inner support tube including second external threads on an outer surface, the second external threads being secured to the internal threads of the first tube, the second inner support tube spaced from the first inner support tube with a first annular groove formed between them; a second lock mechanism disposed at one end of the second tube and including two second lock protuberances and a second externally threaded connection wherein the second externally threaded connection includes a second shoulder adjacent to the second lock protuberances, an inner diameter of the second inner support tube is less than an outer diameter of the second externally threaded connection, the outer diameter of the second externally threaded connection is less than an inner diameter of the first inner support tube so that the second externally threaded connection is disposed in a first end of the second tube and the second shoulder urges against the first end of the second tube, a distance between each of the second lock protuberances and the second shoulder is equal to a length of the first annular groove, the second lock mechanism is moveably secured to the first annular groove, and the second tube is moveably disposed in the first tube; a release mechanism including an axially moveable lock needle having a pointed second end and a pushbutton at a first end, the pushbutton projecting out of the first tube wherein a pressing of the pushbutton moves the lock needle to either insert into or disengage from the second lock mechanism, thereby retracting the second lock protuberances to an unlocked position or extending the second lock protuberances to a locked position; and a positioning member for limiting the release mechanism at a first end of the first tube.
- Preferably, further comprises a first lock mechanism at the first end of the first tube, the first lock mechanism including two first lock protuberances and a first externally threaded connection, the first externally threaded connection including a first shoulder adjacent to the first lock protuberances, the first externally threaded connection being disposed in the first end of the first tube and the first shoulder urges against the first end of the first tube, and the first tube being moveably disposed in a third tube; and a second annular groove formed on an inner surface of the third tube wherein a distance between each of the first lock protuberances and the first shoulder is equal to a length of the second annular groove, and the first lock mechanism is moveably secured to the second annular groove.
- Preferably, further comprises a first through hole axially disposed through the first lock mechanism and a second through hole axially disposed through the second lock mechanism wherein the lock needle is disposed through each of the first through hole and the second through hole to be locked or clears same to be unlocked.
- Preferably, further comprises at least one first O-ring disposed on an outer of the first lock mechanism and at least one second O-ring disposed on an outer of the second lock mechanism.

- Preferably, further comprises a plug threadedly secured to a second end of the second tube.
- The invention has the following advantages and benefits in comparison with the conventional art: Easy forming. This is because after inner surfaces of both the first inner support tube and the second inner support tube are worn to a predetermined extent, both the first inner support tube and the second inner support tube can be pulled out of the first tube and replaced with new ones. The first annular groove can be formed by forming the internal threads and threadedly securing both the first inner support tube and the second inner support tube to the internal threads sequentially. Wall thickness of the first tube is decreased greatly.
- Greatly decreased components replacement cost. This is because the second tube is moveably disposed in the first tube and components are subject to wear and therefore a frequent replacement is required Further, this can greatly decrease the difficulties of manufacturing the first tube. Because the first inner support tube and the second inner support tube are threadedly to inside of the first tube. Thus, only both the first inner support tube and the second inner support tube are required to replace rather than the first tube. In comparison with replacing the first tube, the cost of replacing both the first inner support tube and the second inner support tube is relatively small.
- The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.

As indicated by arrow, thelock needle 31 passes through thesecond lock mechanism 21 to cause thesecond lock mechanism 21 to clear the firstannular groove 14. As a result, thesecond tube 20 is moveably disposed in thefirst tube 10. - The invention has the following advantages and benefits in comparison with the conventional art: After inner surfaces of both the first
inner support tube 121 and the secondinner support tube 122 are worn to a predetermined extent, both the firstinner support tube 121 and the secondinner support tube 122 can be pulled out of thefirst tube 10 by rotation and replaced with new ones. Thus, only both the firstinner support tube 121 and the secondinner support tube 122 are replaced rather than thefirst tube 10. This can greatly decrease the components replacement cost. Further, this can greatly decrease the difficulties of manufacturing thefirst tube 10. The firstannular groove 14 can be formed by forming theinternal threads 11 and threadedly securing both the firstinner support tube 121 and the secondinner support tube 122 to theinternal threads 11 sequentially. - While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
