First moulding 413 of two arrangements that are in the shape of the letter V and the arrangement of the second moulding 414 form " V-frame 412 ", the first moulding 413 and second the angle of moulding 414 can adjust, but since the length of the first moulding 413 and the second moulding 414 is inconsistent, Therefore, not compressible by mutual inhibition when the first moulding 413 and the second moulding 414 are compressed, so as to Enough radial support power is provided for pipe holder 400, that is, " V-frame 412 " has the feature of triangle stability.And the The angle of one moulding 413 and the second moulding 414 can be adjusted, and pipe holder 400 is made to can be realized compression undergauge processing.Elastic strip 422 setting, on the one hand, the connection function between two ring structures 410 of enhancing, to enhance radial support power, another side Face guarantees that V-frame 412 can be made smoothly to realize compression while enhancing radial support power.

In an embodiment of the present embodiment:

As shown in figure 18, the side of the first closed angle end 415 of each V-frame 412 is provided with supplementary structure 430；

Supplementary structure 430 includes two assistant strips 431 of equal length；The length and the second moulding of each assistant strip 431 414 is equal, and each assistant strip 431 is parallel to the setting of assistant strip 431, and one end of each assistant strip 431 and the first closed angle end 415 connect It connects, the other end of each assistant strip 431 is connect with connection strap 421.

Supplementary structure 430 further enhances the radial support power of V-frame 412.

In an embodiment of the present embodiment:

As shown in figure 19, pipe holder 400 is provided with multiple axially spaced internal layer support frames 440；

Support frame 441 of each internal layer support frame 440 including the shape that assumes diamond in shape, center and the pipe holder 400 of support frame 441 Axial line is overlapped, and four angles of support frame 441 are respectively arranged with supported hole 443；

The internal perisporium of pipe holder 400 is provided with the support column 444 that can be correspondingly connected with supported hole 443.

The support frame 441 of shape of assuming diamond in shape plays the role of support to pipe holder 400, to enhance the radial branch of pipe holder 400 Support force；When the pressure of pipe holder 400 is held simultaneously, internal layer support frame 440 also can smoothly compress, and realize the diminution of diameter, so as to It is sent into inside organ after realizing undergauge.

In an embodiment of the present embodiment:

As shown in figure 19, extension and lateral wall energy along the circumferential direction are provided on the outside of four wedge angles of support frame 441 Enough arc-shaped workpieces 442 being bonded with the internal perisporium of pipe holder 400；Supported hole 443 is set to arc-shaped workpiece 442.

Arc-shaped workpiece 442 coincide for realizing internal layer support frame 440 and 400 internal perisporium of pipe holder, to increase internal layer support Effective contact area of frame 440 and pipe holder 400 avoids support force to reduce the size of support force corresponding to unit area It excessively concentrates, so that internal layer support frame 440 can effectively support pipe holder 400.

In an embodiment of the present embodiment:

As shown in figure 19, setting is spaced between the lateral wall of arc-shaped workpiece 442 and the internal perisporium of pipe holder 400.Interval setting, For guaranteeing that internal layer support frame 440 and pipe holder 400 have that enough avoiding spaces smoothly strut and pressure is held, avoid in nature Lower pipe holder 400 oppresses internal layer support frame 440 always, causes the radial support power of internal layer support frame 440 impaired, to influence whole The support force of body.

The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
