Mouse fixing apparatus

The invention provides a mouse fixing apparatus, wherein the mouse fixing apparatus comprises a fixed plate; a head fixing seat which is arranged on the fixed plate and is formed with a groove which is adaptive to the head of a mouse, wherein a through hole is formed in the top of the groove; two body baffle blocks which are symmetrically arranged on the fixed plate by taking the axis of the groove as a centerline; a binding strap which is configured to wind together the two body baffle blocks, the fixed plate and the mouse between the two body baffle blocks; and a hook which is arranged at the upper end of the fixed plate. By virtue of the head fixing base, the fixed plate, the body baffle blocks and the binding strap, the mouse fixing apparatus disclosed by the invention can be used for simultaneously fixing the head and the body of the mouse, so as to prevent the mouse from moving freely. The mouse fixing apparatus is applicable to a mouse radiation exposure device for carrying out a radiation experiment, so as to improve the efficiency and the quality of the radiation experiment.
