Abstract: A jaw assembly and a medical accelerator are provided. The jaw assembly includes: a jaw base, a moving assembly and at least one set of jaws, each set of jaws including at least two jaw bodies. The jaw base is detachably connected to a mounting seat of a treatment head beam shaping module of a medical accelerator, and when the jaw base is mounted on the mounting seat, a beam opening formed is located under the treatment head beam shaping module. The jaw body is connected to the jaw base through the moving assembly, and the moving assembly is configured to move the jaw body to between the beam opening and the treatment head beam shaping module, or to move the jaw body out between the beam opening and the treatment head beam shaping module to adjust a beam flow through the beam opening.

Abstract: A braking device for braking a belt of a downward belt conveyor adopting a head drive is provided. The belt includes first and second belt surfaces opposite to each other. The braking device includes a first clamping plate arranged at a side of the first belt surface, and a second clamping plate arranged at a side of the second belt surface. The first and second clamping plates are configured to move toward each other to allow the second clamping plate and the first clamping plate respectively abut against the second belt surface and the first belt surface, so as to clamp the belt to achieve the braking. The first and second clamping plates are configured to move away from each other to release the belt.
