The invention discloses an unmanned aerial vehicle recovery parachute separation device which comprises an upper connector, a lower connector, a circular ring pin, an explosive bolt and a nut. The upper connector is provided with a connecting seat; an abutting joint hook body is arranged on one side of the upper connector; a through connecting hole is formed in the abutting joint hook body; the structure of the lower connector is the same as that of the upper connector; the abutting joint hook body of the upper connector and an abutting joint hook body of the lower connector are connected in an abutting joint mode; the circular ring pin is inlaid on the connecting hole at the abutting joint position of the abutting joint hook bodies; the explosive bolt penetrates through the connecting hole of the upper connector and a connecting hole of the lower connector; and the nut is fastened with the thread end of the other side of the explosive bolt. The structure is simplified, parts are reduced, load transmitting adopts surface contact, the angle values of an included angle alpha between the load direction and the connector main bodies and an included angle beta between the load direction and the separation surface are rationally arranged, and the unmanned aerial vehicle recovery parachute separation device has the advantages that bearing capacity is large, the weight is small, the structure is simple and reliable, assembling is rapid, and repeatable use is achieved.
