The telescopic oil cylinder comprises a cylinder body and a filtering mechanism which are installed on the working vehicle, the filtering mechanism comprises a filtering box, a rough filtering assembly, a fine filtering piece and an oil return pump, the filtering box is connected to the working vehicle and communicated with the cylinder body, the fine filtering piece is installed in the filtering box, and the rough filtering assembly is communicated with the fine filtering piece. The fine filtering part is used for finely filtering hydraulic oil, the multiple rough filtering assemblies are installed in the filtering box, located between the oil inlet and the fine filtering part and used for preliminarily filtering the hydraulic oil, and the oil scavenging pump is installed on the cylinder body and used for pumping the hydraulic oil into the cylinder body. The oil scavenger pump is communicated between the filter box and the cylinder body, and the operating vehicle is further provided with an oil supplementing assembly for supplementing the hydraulic oil in the cylinder body. The telescopic oil cylinder has the effect of prolonging the service life of the telescopic oil cylinder on the overhead working truck.
