Composite material telescopic rods are a combination of composite material tubes, including carbon fiber telescopic rods, hybrid carbon fiber telescopic rods, and glass fiber telescopic rods. Carbon fiber telescopic rods can be further classified based on different stiffness performances, such as standard modulus carbon fiber telescopic rods, intermediate modulus carbon fiber telescopic rods, high modulus carbon fiber telescopic rods, and ultra-high modulus carbon fiber telescopic rods. There are various connection methods for telescopic rods, including those connected with locking mechanisms, tapered connections, screw connections, and leaf spring connections. Depending on different usage scenarios and requirements, an appropriate connection method can be chosen.
