Press machine for bone fracture plate test

The invention discloses a press machine for a bone fracture plate test in the technical field of press machines. The press machine comprises a base, and two fixing columns and two first supporting plates are fixedly connected to the surface of the base; when the mechanical performance of the bone fracture plate is tested, the first arc-shaped plate and the second arc-shaped plate are utilized, the bone fracture plate can have a large contact area for supporting after being clamped, and therefore it is guaranteed that the bone fracture plate is stably clamped and stably supported, and after the bone fracture plate deforms, the bone fracture plate is not prone to deformation. The clamping block can move towards the bottom of the first groove under the action of the arc-shaped groove, the first arc-shaped plate and the bottom of the bone fracture plate can be kept attached, stable supporting of the fixing position of the bone fracture plate is guaranteed, the clamping block can move towards the bottom of the fir
