The invention relates to a stepless retractable spontoon with freely-adjustable length, belonging to the technical field of
public security and riot
control equipment; the stepless retractable spontoon comprises a base
pipe and a retractable pole and is characterized in that: the retractable pole is sheathed in the base
pipe, the rear end of the retractable pole is connected with an eccentric
locking mechanism which is matched with the base
pipe, and the front end of the retractable pole is connected with the end of the spontoon; a rubber-
plastic compound layer is coated outside the base pipe, and anti-skidding grains are arranged on the rubber-
plastic compound layer. The stepless retractable spontoon has the beneficial effects that: 1. as the eccentric
locking mechanism can be locked tightly and loosed at any position, the length of the spontoon can realize stepless adjustment within a certain range, and once screwing is carried out, the spontoon is tightened, the extension is free and the usage is convenient; 2. the structure is simple, the using property is reliable, the structural intensity of the spontoon is high,
impact force is heavy and the spontoon is not easy to deform; 3. the ends of the spontoon adopt tube-spring structures, the impacting force can be effectively controlled, so as to better realize the purpose of the spontoon.
