Determine anchor ear 5 to be set with and be fixed on tubing, and is respectively arranged at the both sides of cutting-cylinder 1 with handwheel anchor ear 2.
In specific implementation process, under cut state, fixed anchor ear 5 is respectively arranged at cutting-cylinder 1 with handwheel anchor ear 2
Both sides, fixed anchor ear 5 coordinates with handwheel anchor ear 2 fixes pipeline, prevents pipeline from being moved in cutting process.
As shown in figures 1 to 6, fixed anchor ear 5 includes the 5th semicircular cylinder 51 and the 6th semicircular cylinder 52,51 He of the 5th semicircular cylinder
6th semicircular cylinder 52 can be opened, and tubular structure can be also closed into.It cuts with scissors the side of 5th semicircular cylinder 51 and the 6th semicircular cylinder 52
It connects, the other side is connected by fastener.It needs to open the 5th semicircular cylinder 51 and when six semicircular cylinders 52, removes fastener, make the
Five semicircular cylinders 51 and the 6th semicircular cylinder 52 are rotated around hinged place.Pipeline is placed on the 5th semicircular cylinder 51 or the 6th semicircular cylinder 52
Inside after, be closed the 5th semicircular cylinder 51 and the 6th semicircular cylinder 52, and connect using fastener.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
Present invention has been described in detail with reference to the aforementioned embodiments, it will be understood by those of ordinary skill in the art that：It is still
Either which part or all technical features can be carried out so that technical scheme described in the above embodiments is modified
Equivalent replacement；And these modifications or replacements, it does not separate the essence of the corresponding technical solution various embodiments of the present invention technical side
The range of case.
