Rod end knuckle bearing connecting structure of electric push rod

The utility model discloses a connecting structure of a rod end joint bearing of an electric push rod, which relates to a driving device and aims to solve the problem that threads of the rod end joint bearing are loosened due to vibration when the rod end joint bearing is used, and is characterized by comprising an inner pipe and the rod end joint bearing, and a mounting cavity is arranged on the end face of the inner pipe. The rod end joint bearing comprises a screw rod in threaded connection with the inner wall of the mounting cavity, the screw rod is in threaded connection with an opposite-vertex nut, and the end face of the inner pipe is provided with anti-skid threads abutting against the opposite-vertex nut. The abutting nut abuts against the anti-skid lines on the end face of the inner pipe, the friction force between the abutting nut and the end face of the inner pipe is increased, and due to the fact that the abutting nut abuts against the screw rod, when the rod end knuckle bearing rotates relative
