The invention discloses a novel insulating rod connection device. The novel insulating rod connection device is characterized in that the novel insulating rod connection device comprises a front end epoxy insulation rod, a columnar ejecting jaw, a push nut and a multi-groove connection column; the front end epoxy insulating rod is located at the front end of the novel insulating rod connection device; the columnar ejecting jaw is provided with a lantern ring; one end of the push nut is connected with the front end epoxy insulating rod, and the other end of the push rod is connected with the lantern ring; the multi-groove connection column is provided with a reset spring fixing plate; reset springs are arranged between the multi-groove connection column and the reset spring fixing plate; one end of the multi-groove connection column is connected with the front end epoxy insulating rod, and the other end of the multi-groove connection column is connected with an anti-rotation connection body; and the anti-rotation connection body is connected with a rear end epoxy insulating rod. The transmission principle of a screw nut pair is adopted for the novel insulating rod connection device, the push nut is used in cooperation with a thread machined in the front end of the multi-groove connection column for pushing the columnar ejecting jaw to move forwards or backwards, and therefore self-locking and release of connection are achieved, the structure is simple, and the self-locking thread connection reliability is high.
