Description
Technical field
It the utility model is related to a kind of cutting tool technical field, more particularly to a kind of spiral casing knife.
Background technology
In Hydroelectric Project Construction, it is often necessary to cut the tubing such as plastic cement water pipe, in current construction operation, water power work is often led to
Cross blade directly to cut, such operating method causes the tubing critical point out-of-flatness cut, easily to other after installing
People is damaged and again dangerous when being cut using blade, and existing casing knife is not often portable and complicated.
Utility model content
The purpose of this utility model is to provide a kind of spiral casing knife, to solve proposed in the above background technology ask
Topic.
To achieve the above object, the utility model provides following technical solution：
A kind of spiral casing knife, including tube wall, roller, wing bolt, four square tool, screw hole, groove, shaft, circle are pre-
Box out, open up fluted in the tube wall, the inner wall of the groove is opened up integrally formed with several shafts, the roller both ends
There is circular preformed hole, connecting circular preformed hole by shaft in the groove is installed on roller in the groove in tube wall, described
Screw hole is offered at the top of tube wall, the wing bolt bottom is threaded in spiral shell integrally formed with four square tool, the wing bolt
Kong Shang.
Preferably：The outer surface of tube wall is integrally formed with non-slip texture.
Preferably：The tube wall, roller and shaft are made of mould steel, and the wing bolt and four square tool use
High-speed tool steel makes.
The beneficial effects of the utility model are：The utility model is simple in structure, and design is reasonable, easy to operate and small
Ingeniously so that can be carried with when operator works outside and cutting mouth is neat, adapt to the pipe of a variety of different tube diameters.

Embodiment
The utility model is further elaborated with specific embodiment below in conjunction with the accompanying drawings：
As shown in figures 1 to 6, a kind of spiral casing knife, including tube wall 1, roller 2, wing bolt 3, four square tool 4, screw hole 5,
Groove 6, shaft 7, circular preformed hole 8, open up fluted 6 in the tube wall 1, the inner wall of the groove 6 is integrally formed with some
A shaft 7,2 both ends of roller offer circular preformed hole 8, and connecting circular preformed hole 8 by shaft 7 in the groove 6 will
Roller is installed in the groove 6 in tube wall 1, and the top of tube wall 1 offers screw hole 5, and 3 bottom of wing bolt is integrally formed
There is four square tool 4, the wing bolt 3 is threaded on screw hole 5.1 outer surface of tube wall is integrally formed with non-slip texture.Institute
State tube wall 1, roller 2 and shaft 7 to be made of mould steel, the wing bolt 3 and four square tool 4 use high-speed tool steel
Make.
The utility model application method：Tube wall 1 is inserted in tubing, is adjusted to need the position cut, utilizes butterfly spiral shell
Bolt 3 fasten so that four square tool 4 withstand outer pipe wall, tubing is held on the other hand, the other hand hold tube wall 1 rotate a circle i.e. complete cut
Cut operation.
The utility model is simple in structure, and design is reasonable, easy to operate and compact so that can when operator works outside
To carry with and cutting mouth is neat, the pipe of a variety of different tube diameters is adapted to.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of the spirit or essential attributes without departing substantially from the utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, in all respects, the embodiments should be taken as exemplary, therefore the equal change in equivalency range
All include in the scope of the utility model.
