The rotation of the second screw 204 drives the two fixed blocks 303 thereon to move toward each other. The fixed blocks 303 move toward each other and drive the connecting bracket 302 of its outer ring to move. The movement of the connecting bracket 302 drives the support frame 301 to move. The movement of the support frame 301 drives the deflection mechanism 4 thereon to move. Then, the two deflection mechanisms 4 are brought close to each other and the clamps 407 thereon are brought close to each other, so that the two sections of the power cable protection pipe are clamped and fixed. The hot-melt butt-jointing machine 6 is used to perform hot-melt operation on the ends of the two sections of power cable protection tubes that are close to each other.

The rotation of the second drive shaft 105 drives the second sleeve 212 of its outer ring to rotate.
