When the outer side wall of the reducing inner cylinder rotates, the inner diameter of the reducing inner cylinder synchronously changes, and the inner diameters of the protective sleeve and the reducing outer ring synchronously change.

The electric threading pipe port protection device is characterized in that: the hole of protective sheath is the ellipse, and elasticity fastener is the S-shaped, and the crest department on elasticity fastener upper portion is the outside of reducing inner tube dorsad, and the trough department of elasticity fastener lower part supports the lateral surface of reducing inner tube.

The electric threading pipe port protection device is characterized in that: the reducing inner cylinder adopts the following structure to change the size of the inner diameter: the cross section of the reducing inner cylinder is an arc with two overlapped ends, and the central angle corresponding to the arc is positioned atπ～Pi, i.e. the central angle of the overlapping part of the circular arcs isπ～And pi, when the reducing inner cylinder contracts inwards, the overlapped part of the circular arcs is increased, the inner diameter of the reducing inner cylinder is reduced, and when the reducing inner cylinder expands outwards, the overlapped part of the circular arcs is reduced, and the inner diameter of the reducing inner cylinder is increased.

The utility model discloses during the use, adjust the internal diameter of reducing inner tube to match mutually with the external diameter of spool, insert the spool with the reducing inner tube, thereby make the turn-ups of protective sheath cover the terminal surface of spool, thereby the lateral wall that makes the inner of elasticity fastener lower part support the spool under the effect of self elasticity fixes the reducing inner tube on the spool, can wear to establish all kinds of cables in the spool afterwards. The utility model discloses a under the protection, the cable has avoided taking place wearing and tearing with the port of spool, under the fixed of elasticity fastener, the utility model discloses can firmly fix and avoid droing on the spool.

the utility model discloses following beneficial effect has: can effectually form protection architecture at mouth of pipe tip, stop orificial protection architecture and do not have the fixed point and produce and drop, cause the emergence of the damage phenomenon of cable, simultaneously, avoided the cable to cause life's book damage because of wearing and tearing, reduced later stage manual input, practiced thrift the cost.
