The overturning driver 4 comprises a driving rotary block 401, a worm 402, a worm wheel 403 and a rotary sleeve 404; a worm 402 with one end fixed with a driving rotating block 401 is rotationally matched on the workbench body 1 through a vertical frame, and the worm 402 is engaged with a worm wheel 403 fixed on a rotating sleeve 404 in a transmission way; the rotating sleeve 404 is rotatably fitted on the bearing seat 309, the inner side of the rotating sleeve 404 is slidably fitted with the turning shaft 308, and the groove on the turning shaft 308 is slidably fitted with the protrusion on the inner side of the rotating sleeve 404. The rotation driving rotating block 401 can drive the worm 402 to rotate, the worm 402 rotates to drive the worm wheel 403 and the rotating sleeve 404 to rotate, the rotating sleeve 404 can drive the overturning shaft 308 to rotate through the matching of the convex block and the groove of the overturning shaft 308 when rotating, so that the overturning motion of the overturning hanging bracket 3 is controlled, and due to the structural properties of the worm 402 and the worm wheel 403, the self-locking of the position of the overturning hanging bracket after overturning adjustment is realized, so that the animal can be observed at different inclination angles conveniently.

The overturning hanger 3 further comprises a pull disc, an extension spring and a limiting bolt; the pull disc is fixed at the outer end of the turning shaft 308 and fixedly connected with the bearing seat 309 through an extension spring, the bearing seat 309 is in threaded fit with a limiting bolt, the limiting bolt is pressed on the turning shaft 308, and the inner end of the turning shaft 308 can be inserted into an insertion slide way penetrating through the fixing screw 7. The inner end of the turnover shaft 308 can be inserted into an insertion slide way which runs through the fixing screw rod 7, so that the claw binding ring 5 is positioned when the claw binding ring 5 is not required to rotate, when the claw binding ring is required to rotate, the pull disc is pulled outwards to drive the extension spring to stretch and simultaneously drive the turnover shaft 308 to be separated from the insertion slide way of the fixing screw rod 7, then the limiting bolt is rotated to be pressed on the turnover shaft 308 to enable the turnover shaft 308 to be relatively fixed, and at the moment, the claw binding ring 5 can be controlled to rotate.
