Description
Technical field
The utility model relates to a kind of expansion holding meanss.
Background technique
In intraperitoneal hemorrhage operation, when being performed the operation, it usually needs omentum majus is raised with group stick and is removed to one side,
Then blood is removed, but omentum majus is very wet and slippery, often the back sliding removing influenced in operation to blood, is easy delay disease
Feelings.There is presently no practical devices can solve the above problem.
Utility model content
In view of the deficienciess of the prior art, the utility model provides a kind of expansion holding meanss, structure is simple, uses
It is convenient, safety and stability.
To achieve the above object, the utility model provides following technical solution: a kind of expansion holding meanss, including shell
Body, control shaft and two expanded support sticks, the housing forward end are provided with opening, and the control shaft is rotatably arranged in shell, control
Axis front end corresponding housing opening position is provided with screw thread, and control shaft rear end extends and is fixedly and coaxially connected from housing rear end
There is knob, two expanded support stick rear ends are installed with gear, and described two cogged one end of expanded support stick are rotatably provided in shell
At on the inside of front opening and control shaft two sides are located at, control shaft nose threads engage respectively with the gear of two expanded support sticks,
One of expanded support stick is fluted towards opening up on the end face of another expanded support stick, is provided with rotation axis in groove, in rotation axis
Retracting has roll paper, and the roll paper other end is fixedly connected on another expanded support stick.
By adopting the above technical scheme the advantages of is: two expanded support sticks are rotatably set in shell, and control shaft passes through shell
It is engaged with two expanded support sticks, control shaft is fixedly connected with knob, drives control shaft rotation by turning knob, control shaft rotates band
Dynamic two expanded support sticks are swung with realizing the mesh for holding together two expanded support bastinade foldings, and roll paper is arranged between two expanded support sticks,
Roll paper with can rotate releasing when two expanded support sticks are opened together from rotation axis, when use be set to two expanded support sticks it
Between roll paper omentum majus raise removing, raise except when be not easy to have skidded.The utility model structure is simple, easy to use, peace
It is complete to stablize.
As further improvement of the utility model: the rotation axis both ends are provided with reduction torsion spring.
By adopting the above technical scheme the advantages of is: the setting of reduction torsion spring can allow roll paper multiple with utilizing when expanded support axis closes up
The restoring force of position torsional spring can automatically revert to the state before opening by roll paper, and roll paper is opening Shi Nengli with expanded support axis
Roll paper is collapsed tightly with the restoring force of reduction torsion spring.
As further improvement of the utility model: the knob is circumferentially evenly equipped with non-slip groove.
By adopting the above technical scheme the advantages of is: non-slip groove can allow user to be more easier turning knob and prevent from skidding.
As further improvement of the utility model: setting is anti-there are two that can cooperate with housing rear end in the control shaft
The only fixinig plate of control shaft axial displacement.
By adopting the above technical scheme the advantages of is: fixinig plate can allow control shaft to be rotatably fixed on shell, pass through control
The rotation of axis is held together to control two expanded support bastinade foldings, is prevented control shaft from the displacement in axial direction occur, is made its screw thread and expanded support stick
Gear engagement it is more stable, it is not easy to be detached from.

Specific embodiment
The implementation of the expansion holding meanss of the utility model is for example shown in attached drawing 1 to 5: a kind of expansion holding meanss, including
Shell 1, control shaft 2 and two expanded support sticks 3,1 front end of shell are provided with opening, and the control shaft 2 is rotatably arranged on shell 1
Interior, 2 front end corresponding housing of control shaft, 1 opening position is provided with screw thread 4, and 2 rear end of control shaft is extended simultaneously from 1 rear end of shell
It is fixedly and coaxially connected knob 5, two 3 rear ends of expanded support stick are installed with gear 6, and described two expanded support sticks 3 have one end of gear 6
At being rotatably provided on the inside of 1 front opening of shell and it is located at 2 two sides of control shaft, 2 nose threads 4 of control shaft and two expansions
The gear 6 of support stick 3 engages respectively, and one of expanded support stick 3 is towards opening up fluted, groove on the end face of another expanded support stick 3
It is inside provided with rotation axis 7, retracting has roll paper 8 in rotation axis 7, and 8 other end of roll paper is fixedly connected on another expanded support stick 3.
In the present embodiment, 7 both ends of rotation axis are provided with reduction torsion spring 9.
In the present embodiment, the knob 5 is circumferential is evenly equipped with non-slip groove 10.
In the present embodiment, there are two can cooperate to prevent 2 axis of control shaft with 1 rear end of shell for setting in the control shaft 2
To the fixinig plate 11 of displacement.
Above example, only one kind of the utility model preferably specific example, those skilled in the art are practical new at this
The usual variations and alternatives carried out in type technical proposal scope are included in protection scope of the present invention.
