Abstract
The utility model discloses a kind of jaw type pipe-expander, including handle 1, tube supporting part 2 and spring assembly 3, compared with prior art, the technology has advantages below:It is laborsaving, traditional manual pipe-expander needs to overcome larger power to complete tube process, and a kind of jaw type pipe-expander disclosed in the utility model needs only to overcome when in use the repulsion of spring, the left support of tube supporting part and right support are agreed with into a cylinder, the pipeline of required tube is placed on tube supporting part, loosing one's grip can be easily accomplished tube process;It is adjustable, by setting the rope of both fixing end A, B and connection on handle, the size of pipeline after tube can be limited, pipeline will not be damaged, can be applied to the tube operation of the pipeline of different-diameter specification;Portable, the pipe-expander overall volume is small, and weight is suitable, can be positioned in tool box, is easy to carry.
Description
Technical field
The utility model designs tube field of tool, particularly a kind of jaw type pipe-expander.
Background technology
At present, pipe-expander has two kinds of Manual pipe increaser and hydraulic pipe expanding device.Wherein Manual pipe increaser structure by grip part and
The one pressure head composition with taper, when in use using hard pressing method, the tapered pressure head press-in pipe of band so as to by pipe
A kind of Manual lever-type tube expander of spreading, such as Publication No. CN201361663, the operation principle of the invention is leverage,
Connecting line of the relative both sides of the upper and lower tube of drive in rear side linear contact lay is rotated for fulcrum rotates using closing up for two handles,
So that the contact surface of upper tube and lower tube in front side opens, the diameter change of the stepped cylindrical structure of a both sides that make to rise and increase
Greatly, so as to the pipe spreading of a certain stepped cylindrical section will be enclosed within, the pipe-expander needs the strength for overcoming larger, and operation is arduously.And
Although hydraulic pipe expanding device tube speed is fast, accessory is more, takes up room big, and the requirement sealing and precision between accessory is all very
Height, cost of manufacture is too high, is unfavorable for popularization and application.
The content of the invention
To overcome the above-mentioned drawback of existing manual and hydraulic pipe expanding device, the invention provides a kind of simple structure, makes
With a kind of laborsaving, cheap jaw type pipe-expander.
To achieve the above object, the utility model uses following technical scheme:
A kind of jaw type pipe-expander, including handle, tube supporting part and spring assembly, it is characterised in that:The handle bag
Left handle and right handles are included, is articulated and connected between the left handle, right handles, the left handle, the upper end of right handles set respectively
There is protruding end, the tube supporting part includes left support and right support, and the tube supporting part is fixedly installed on protruding end, institute
The lower end that spring assembly is installed on protruding end is stated, the pipe-expander also includes being arranged at the fixing end A of left handle, is arranged at right handles
Fixing end B and connection both rope.
Further, when clamping force compresses handle, the protruding end set in the left handle, right handles is agreed with, and is risen
Mutually agree between pipe supporting part.
Further, the left support, right support are corresponding semicylinder.
The beneficial effects of the utility model are as follows:Laborsaving, traditional manual pipe-expander needs to overcome larger power to complete
Tube process, and a kind of jaw type pipe-expander disclosed in the utility model needs only to overcome when in use the repulsion of spring, will rise
The left support of pipe supporting part agrees with into a cylinder with right support, and the pipeline of required tube is placed on into tube supporting part
On, loosing one's grip can be easily accomplished tube process;It is adjustable, by setting both fixing end A, B and connection on handle
Rope, can limit the size of pipeline after tube, will not damage pipeline, can be applied to the tube behaviour of the pipeline of different-diameter specification
Make;Portable, the pipe-expander overall volume is small, and weight is suitable, can be positioned in tool box, is easy to carry.

Specific embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is described in further detail.
A kind of jaw type pipe-expander, including handle 1, tube supporting part 2 and spring assembly 3, it is characterised in that:The handle
1 includes left handle 11 and right handles 12, is articulated and connected between the left handle 11, right handles 12, the left handle 11, right handles
12 upper end is respectively equipped with protruding end 13, and the tube supporting part 2 includes left support 21 and right support 22, the tube supporting part
2 are fixedly installed on protruding end 13, and the spring assembly 3 is installed on the lower end of protruding end 13, and the pipe-expander also includes being arranged at
The rope of both the fixing end A111 of left handle 11, the fixing end B121 for being arranged at right handles 12 and connection.
Further, when clamping force compresses handle, the contract of protruding end 13 set in the left handle 11, right handles 12
Close, mutually agree between left support 21 and right support 22.
Further, the left support 21, right support 22 are corresponding semicylinder.
Above-mentioned implementation method is only for illustration of the utility model, rather than to limitation of the present utility model, relevant technology neck
The those of ordinary skill in domain, in the case of the spirit and scope for not departing from utility model, can also make a variety of changes and become
Type, therefore all equivalent technical schemes fall within category of the present utility model.
