The invention discloses a jacking rod type truck rear-end collision protector. The jacking rod type truck rear-end collision protector comprises a sensor, a locking mechanism and a jacking rod mechanism. The sensor is arranged on a rear bumper of a truck. The locking mechanism comprises an electromagnetic tractor and a jacking rod blocking pin, the electromagnetic tractor is fixedly arranged on a truck girder at the bottom of the truck, the input end of the electromagnetic tractor is electrically connected with the output end of the sensor, and the output end of the electromagnetic tractor is connected with the jacking rod blocking pin. The jacking rod mechanism comprises a connecting portion and a jacking rod portion, wherein the connecting portion is hinged to the truck girder, and the jacking rod portion is clamped on the jacking rod blocking pin. The jacking rod type truck rear-end collision protector has the advantages that when rear-end collision happens, the rear bumper of the truck is jacked to be bent by a car, the sensor senses the situation and sends a signal to the electromagnetic tractor, and the electromagnetic tractor drives the jacking rod blocking pin to retract to enable the jacking rod portion to be separated from the truck girder, so that the jacking rod portion rotates around a hinge joint point of the connecting portion and the truck girder clockwise; when the car continues moving ahead, the jacking rod portion jacks the lower middle of a car head, and since the lower middle of the car head is high in strength and capable of bearing high impact force, the car can be stopped from plunging into the bottom of the truck, and car destruction and death of persons are avoided.
