The specific embodiment

Shown in Fig. 1,2,3,4, this corrugated tube end pressing instrument comprises first component 1, second component 2.

First component 1 is cylindric, is comprised of the epimere 11 that divides vertically and hypomere 12.

Described epimere 11 is by the first semicolumn 111, the second semicolumn 112 hinged forming, the axially parallel of jointed shaft 13 and first component 1.Be provided with the shoulder hole that is made of roundlet through hole 113 and large round tube hole 114 in the described epimere 11, roundlet through hole 113 is positioned at the top of large round tube hole 114; Described roundlet through hole 113 is formed by the smaller part circular groove fastening that is separately positioned on the first semicolumn 111, the second semicolumn 112, and described large round tube hole 114 is formed by the more than half circular groove fastening that is separately positioned on the first semicolumn 111, the second semicolumn 112.
