[0023] The upper end of the right surface of the mounting plate 1 is fixedly connected with a mounting frame 8, and the upper surface of the mounting plate 1 is fixedly connected with a reinforcement plate 10, which is clamped with the mounting frame 8 to improve the stability of the mounting frame 8. The interior of the mounting frame 8 is slidably connected with a mounting block 9, and the upper ends of the right surface of the mounting block 9 and the side surfaces of the reinforcement ring 3 are fixedly connected with a universal joint 7, and a stretching rod 6 is fixedly connected between the two universal joints 7. The mounting block 9 and the stretching rod 6 cooperate with each other to provide longitudinal tension for the shaft body 2, thereby further reducing the load-bearing burden of the shaft body 2.

[0024] A contoured groove 11 is provided on the right surface of the mounting plate 1. When the filter press is not in use, the reinforcement ring 3 and the stretching rod 6 are both located inside the contoured groove 11.
