[0002] The slaughtering industry used to be operated manually. Now under the mechanized operation mode, the slaughtering industry is also updating to automatic mechanization. In the automatic slaughtering process, splitting a pig in half means splitting the pig in half. There are currently two ways to split a pig in half. One is to use a saw blade to split the pig in half, and the other is to use a machete to split the pig directly. These two skinning methods are prone to jagged cuts on the pig's back after splitting the pig in half, which leads to the problem of unsightly pig skin on the pig's back. Utility Model Content

[0003] The purpose of the utility model is to overcome the defects of the prior art and provide a pig splitting and skinning mechanism to solve the problems existing in the above-mentioned background technology.
