The movable end of the electric push rod 9 is fixedly provided with the spreading plate 13. The tightening ring 12 and the spreading plate 13 can be simultaneously driven to work by the transmission mechanism to clamp from the outside of the bar and to tension from the inner side wall of the bar.

[0023] The tightening ring 12 is arranged on the outer surface of the clamping plate 4. The clamping plate 4 and the tightening ring 12 are in contact with each other on the surface, and the contact surface is an inclined surface.
