The invention relates to a holding claw mechanism of a split type horizontal garbage compressor as well as the split type garbage compressor provided with the holding claw mechanism and a manufacturing method for the split type garbage compressor. The holding claw mechanism of the split type horizontal garbage compressor comprises a power assisting part, a linkage part and a holding claw part, wherein the power assisting part is connected with the linkage part; the linkage part is connected with the holding claw part; under pushing and shrinking of the power assisting part, the linkage part enables the holding claw part to realize horizontal movement and rotary motion. The holding claw mechanism realizes compound motion of horizontal movement and rotation, and further reduces compression force borne on a hydraulic cylinder in multiples.
