Abstract
The invention relates to a retractable spontoon, which mainly solves the problems that retractable rods of the existing spontoon are connected through clamping of elastic parts, so that the spontoon is greatly hindered in usability, and that the existing spontoon has low capability to bear impact of vertical force in stretched state, is poor in stability, consequently has reduced reliability and is inconvenient to use. According to the invention, a bottom pipe is matched with a middle pipe through a locking device; and a top rod can slide axially to drive the locking device to radially move to form axial limit matching or axial slidable matching of the middle pipe and the bottom pipe. A retractable holding structure of the retractable spontoon adopts an inner groove transverse-locking device; when in stretched state, the retractable spontoon can bear impact of any vertical force without retreating, so that the stability is good, the reliability is high, and the usability is effectively improved. The retractable spontoon has good wear resistance, waterproof effect, good tightness and low noise, is convenient to open, close, stretch and retract, needs no additional force, and is reliable and flexible.
