The invention discloses a full-hydraulic-drive lens support. The full-hydraulic-drive lens support is formed by connecting a base plate, a hydraulic pump, a vertical beam, a transverse beam, an inclined beam, a ball head assembly and a rod end knuckle bearing. Universal trundles are arranged at the bottoms of the four legs of the base plate. The base plate is connected with the vertical beam. The upper end of a top rod of the vertical beam is connected with the ball head assembly. The ball head assembly is sequentially connected with the transverse beam, the rod end knuckle bearing and a laparoscope. The inclined beam is connected between a cylinder body of the transverse beam and a cylinder body of the vertical beam, the transverse beam, the vertical beam and the inclined beam are made of both-way oil cylinders, oil is supplied to the oil cylinders through the hydraulic pump and a hydraulic valve, accordingly, the relative position of the laparoscope and the human body is adjusted, and the full-hydraulic-drive lens support is very convenient to use and practical.
