an outer tube (3100) having:
insertion holes (3101) where the pair of support arms (2200) are inserted, and
retainer mounting holes (3102);
an inner carriage (3200) that slides inside the outer tube (3100), and having:
a rear sub-carriage (3230), with the same, but smaller, cross-tube sectional shape as the tube (3100), and having
an upper slot (3232) of the rear sub-carriage,
a lower slot (3233) of the rear sub-carriage immobilizing a respective divider (3240), and
a rear retention hole (3231) in the form of a slotted hole with two sections of different widths, wherein a larger section of the slotted hole coincides in an open position with the insertion holes (3101), and a smaller section that strangles the retention slots (2300) of the support arms (2200) in a closed position;
a front sub-carriage (3220) segment of the same tube cross-section as the rear sub-carriage (3230) and having:
an upper slot (3224) of the front sub-carriage segment and a lower slot (3223) of the front sub-carriage segment, and being equivalent to the respective upper slot (3232) and lower slot (3233) of the rear sub-carriage (3230),
a front retention hole (3221) equivalent to the rear retention hole (3231), and
travel slots (3222) to restrict the travel of the inner carriage (3200) when their front and rear flanks of the inner carriage collide with a retainer (3500);
a latch (3210), in the form of a rectangular plate having:
front and rear slots (3212 and 3213),
a locking hole (3211) into which a latch bolt (3410) snaps when sliding the inner carriage (3200), blocking the inner carriage (3200); and
the divider comprising front and rear dividers (3240) in the form of identical plates having fitting slots (3241) to respectively interlock with the front and rear slots (3212 and 3213) of the latch (3210);
an opening spring (3600) placed between a lock bracket (3300) and the front divider (3240) of the front sub-carriage (3220);
the retainer (3500); being a plate crossing the retainer mounting holes (3102), the travel slots (3222) and retainer blocking holes (3312), and having a blocking recess (3501) on one side to engage with the rear end of a lock (3400) to block the lock (3400);
the lock (3400) having a cylindrical body and including the latch bolt (3410) that retracts when the lock (3400) is in an open position, the latch bolt (3410) having a flat front face, so as when the latch bolt (3410) slides into the locking hole (3211), the inner carriage (3200) is locked, and an inclined rear face to allow the latch (3210) to slide from the open position to a locked position; and
the lock bracket (3300) covering a forward end portion of the detachable retaining bar (3000), leaving access only for inserting the lock (3400), and housing and immobilizing the lock (3400) in a final position; the lock bracket (3300) comprises:
a lock socket (3310), in the form of a cylindric tube segment housing the lock (3400) and having:
a latch bolt hole (3311), through which the latch bolt (3410) exits,
the retainer blocking holes (3312), through which the retainer (3500) passes, and
cap assembly slots (3314) to interlock with a cap (3320);
the cap (3320), in the form of a rectangular tube segment covering the front end of the retaining bar (3000); the cap (3320) positions and immobilizes the lock (3400) transversely and has
a lock insertion hole (3321), and
a socket assembly slot (3322) where the lock socket (3310) interlocks.
