Detailed Description

In order to make the technical solutions of the present invention better understood and make the above features, objects, and advantages of the present invention more comprehensible, the present invention is further described with reference to the following examples. The examples are intended to illustrate the utility model only and are not intended to limit the scope of the utility model.

As shown in fig. 1 to 3, the present invention includes: the autopsy supporting device comprises rolling shafts 2 for supporting autopsy 1, crank arms 3, connecting rods 4, a screw rod 5, a screw rod nut 6 and a screw rod nut seat 7, wherein a pair of rolling shafts 2 are arranged, two ends of each rolling shaft 2 are connected to the crank arms 3, the other ends of the crank arms 3 are fixed on the screw rod nut seat 7 through the connecting rods 4, the screw rod nut seat 7 is installed on the screw rod 5 through screw rods 6 in a threaded mode, and the screw rod 5 is arranged in a box body of an autopsy table;
