Optionally, in this embodiment, the clamping structure includes an elastic fixing arm 21, and the elastic fixing arm 21 can ensure that it enters the connecting tubes 4 with different inner diameters, so as to improve the versatility of the connecting tube dismounting tool. The elastic fixing arm 21 is connected with one end of the lifting structure, so that the elastic fixing arm 21 can be driven to move together when the lifting structure moves upwards, and the aim of lifting the butt joint pipe 4 is fulfilled.

In detail, the elastic fixing arm 21 includes an elastic portion 211 and a hook 212, the hook 212 is disposed toward the inner wall of the adapter tube 4, and the hook 212 can extend out of the adapter tube 4 and abut against the end of the adapter tube 4. Therefore, the draw hook 212 can not slide relative to the end part of the connecting pipe 4 in the process of drawing the connecting pipe 4, and the aim that the draw hook 212 can stably draw the connecting pipe 4 can be achieved. In addition, the distance between the working end of the draw hook 212 and the central axis of the top pressing unit 1 is larger than the radius of the connecting pipe 4, so that the draw hook 212 can be abutted against the end part of the connecting pipe 4 after extending out of the inner hole of the connecting pipe 4.

Of course, in some other embodiments, when the smoothness of the side wall of the inner hole of the connection pipe 4 is relatively poor with respect to the outer side wall, the detachment of the connection pipe 4 can be realized by the abutting mode of the elastic fixing arm 21 and the side wall of the inner hole of the connection pipe 4, at this time, the elastic fixing arm 21 includes the elastic portion 211 and the arc-shaped contact piece, the arc-shaped contact piece is connected with the elastic portion 211, the arc-shaped contact piece is provided with a plurality of protrusions to increase the friction force with the inner hole side wall of the connection pipe 4, the relative sliding displacement between the arc-shaped contact piece and the inner hole of the connection pipe 4 is reduced, the contact area between the arc-shaped contact piece and the inner hole side wall of the connection pipe 4 can be increased by the fitting of the arc-shaped contact piece and the inner side wall of the connection pipe 4, and the friction between the arc-shaped contact piece and the inner hole side wall is further improved.

Alternatively, in the present embodiment, the pulling unit 2 includes a pulling column 22, and one end of the pulling column 22 passes through the pressing unit 1 and is connected to the elastic fixing arm 21. The pulling column 22 can drive the elastic fixing arm 21 to move towards the direction far away from the pipe joint 3 in the pulling process, and the pulling column 22 can be a polished rod, so that the structure is easy to obtain, and the manufacturing cost is reduced.
