Split type multi-parameter controllable inter-fruit collision recovery coefficient testing device

The utility model discloses a split type multi-parameter controllable device for testing collision recovery coefficients among fruits. The split type multi-parameter controllable device comprises a positioning frame, an image acquisition unit and two collision testing units which are arranged on the positioning frame and are symmetrical left and right, the collision test unit comprises a frame, a guide rail, an electric push rod, an electromagnet adsorption device and a trolley, the guide rail is obliquely hinged to the top of the frame and is jacked by the electric push rod below the guide rail, the electromagnet adsorption device and the trolley are slidably mounted on the guide rail, and the trolley can be adsorbed by the electromagnet adsorption device; the image acquisition unit is used for shooting the whole collision process between test objects, and the cooperation of a reflector plate and a light-emitting background plate can eliminate shadows and clearly observe the Z-axis movement after particle co
